FUNCTIONAL DESCRIPTION INTRODUCTION FUNCTIONAL DESCRIPTION INTRODUCTION FUNCTIONAL PIN DESCRIPTION CHARGER CHRGRAW 1. Charger input. The charger voltage is measured through an ADC at this pin. The UVBUS pin must be shorted to CHRGRAW in cases where the charger is being supplied from the USB cable. The minimum voltage for this pin depends on BATTMIN threshold value (see Battery Management). 2. Output to battery supplied accessories. The battery voltage can be applied to an accessory by enabling the charge path for the accessory via the CHRGRAW pin. To accomplish this, the charger needs to be configured in reverse supply mode. CHRGCTRL1 Driver output for charger path FET M1. CHRGCTRL2 Driver output for charger path FET M2. CHRGISNS Charge current sensing point 1. The charge current is read by monitoring the voltage drop over the charge current 100 mΩ sense resistor connected between CHRGISNS and BPSNS. BPSNS 1. BP sense point. BP voltage is sensed at this pin and compared with the voltage at CHRGRAW. 2. Charge current sensing point 2. The charge current is read by monitoring the voltage drop over the charge current 100 mΩ sense resistor. This resistor is connected between CHRGISNS and BPSNS. BP This pin is the application supply point, the input supply to the IC core circuitry. The application supply voltage is sensed through an ADC at this pin. BATTFET Driver output for battery path FET M3. If no charging system is required, the pin BATTFET must be floating. When single path is implemented, it must be connected to ground.

BATT Battery positive terminal. Battery current sensing point 2. The supply voltage of the battery is sensed through an ADC on this pin. The current flowing out of and into the battery can be read via the ADC by monitoring the voltage drop over the sense resistor between BATT and BATTISNS. BATTISNSCC Accumulated current counter current sensing point. This is the coulomb counter current sense point. It should be connected directly to the 0.020 Ω sense resistor via a separate route from BATTISNS. The coulomb counter monitors the current flowing in/out of the battery by integrating the voltage drop over the BATTISNCC and the BATT pin. CFP AND CFM Accumulated current filter cap plus and minus terminals respectively. The coulomb counter will require a 10 µF output capacitor connected between these pins to perform a first order filtering of the signal across R1. CHRGSE1B An unregulated wall charger configuration can be built in which case this pin must be pulled low. When charging through USB, it can be left open since it is internally pulled up to VCORE. The recommendation is to place an external FET that can pull it low or left it open, depending on the charge method. CHRGLED Trickle LED driver output 1. Since normal LED control via the SPI bus is not always possible in the standalone operation, a current sink is provided at the CHRGLED pin. This LED is to be connected between this pin and CHRGRAW.

In typical applications, SW1, SW2, and SW3 will both be kept active for the processor modules in state retention, and SW4 retained for the external memory in self refresh mode. SW1, SW2, and SW3 power gating FET drive would typically be connected to PWGTDRV1 (for parallel NMOS switches). SW4 power gating FET drive would typically be connected to PWGTDRV2. When low power Off mode is activated, the power gate drive circuitry will be disabled, turning off the NMOS power gate switches to isolate the maintained supply domains from any peripheral loading.

FUNCTIONAL DESCRIPTION FUNCTIONAL PIN DESCRIPTION WDI To ensure that shared resources are properly powered when required, the system will only be allowed into Standby when both the application processor (which typically controls the STANDBY pin) and peripherals (which typically control the STANDBYSEC pin) allow it. This is referred to as a Standby event. The Standby pins are programmable for Active High or Active Low polarity, and that decoding of a Standby event will take into account the programmed input polarities associated with each pin. Since the Standby pin activity is driven asynchronously to the system, a finite time is required for the internal logic to qualify and respond to the pin level changes. Watchdog input. This pin must be high to stay in the On mode. The WDI IO supply voltage is referenced to SPIVCC (normally connected to SW4=1.8 V). SPIVCC must therefore remain enabled to allow for proper WDI detection. If WDI goes low, the system will transition to the Off state or Cold Start (depending on the configuration). STANDBY AND STANDBYSEC Standby input signal from processor and from peripherals respectively. Table 8. Standby Control Pins STANDBY (PIN) STANDBYINV (SPI BIT) STANDBYSEC (PIN) STANDBYSECINV (SPI BIT) STANDBY CONTROL(42) 0 0 x x 0 x x 0 0 0 1 1 x x 0 x x 1 1 0 0 1 0 1 1 0 1 1 0 1 1 0 0 1 1 1 0 1 0 1 Notes 42. STANDBY = 0: System is not in Standby; STANDBY=1: System is in Standby and Standby programmability is activated. The state of the Standby pins only have influence in the On mode and are therefore ignored during start up and in the Watchdog phase. This allows the system to power up without concern of the required Standby polarities, since software can make adjustments accordingly, as soon as it is running. INT Interrupt to processor. Unmasked interrupt events are signaled to the processor by driving the INT pin high. PWRON1, 2 AND 3 A turn on event can be accomplished by connecting an open drain NMOS driver to the PWRONx pin of the 13892, so that it is in effect a parallel path for the power key. PUMS1 AND PUMS2 Power up mode supply setting. Default start-up of the device is selectable by hardwiring the Power Up Mode Select pins. The Power Up Mode Select pins (PUMS1 and PUMS2) are used to configure the start-up characteristics of the regulators. Supply enabling and output level options are selected by hardworking the PUMS pins for the desired configuration. The following power up defaults table shows the initial setup for the voltage level of the switchers and regulators, and if they get enabled or not, according to the PUMS pins configuration. 13892 Analog Integrated Circuit Device Data Freescale Semiconductor 43 Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not available from Freescale for import or sale in the United States prior to September 2010: MC13892VK and MC13892VL in 139, 186 MAPBGA packages.

SPIVCC Supply for SPI bus and audio bus CS CS held low at Cold Start configures the interface for SPI mode. Once activated, CS functions as the SPI Chip Select. CS tied to VCORE at Cold Start configures the interface for I2C mode; the pin is not used in I2C mode other than for configuration. Because the SPI interface pins can be reconfigured for reuse as an I2C interface, a configuration protocol mandates that the CS pin is held low during a turn on event for the IC (a weak pull-down is integrated on the CS pin). CLK Primary SPI clock input. In I2C mode, this pin is the SCL signal (I2C bus clock). MOSI Primary SPI write input.

When SWBST is configured to supply the UVBUS pin in OTG mode, the feedback will switch to sense the UVBUS pin instead of the SWBSTFB pin. thermistor must be biased with an external pull-up to a voltage rail greater than the ADC input range. In order to save current when the thermistor reading is not required, it can be biased from one of the general purpose IOs such as GPO1. A resistor divider network should assure the resulting voltage falls within the ADC input range, in particular when the thermistor check function is used. VUSB ADIN6 This is the regulator used to provide a voltage to an external USB transceiver IC. ADC generic input channel 6. ADIN6 may be used as a general purpose unscaled input, but in a typical application, the PA thermistor is connected here. VINUSB Input option for VUSB; supplied by SWBST. This pin is internally connected to the UVBUS pin for OTG mode operation (for more details about OTG mode See OTG mode (On the Go) on page 64). Note: When VUSBIN =1 , UVBUS will be connected via internal switches to VINUSB and incur some current drain on that pin, as much as 270uA maximum, so care must be taken to disable this path and set this SPI bit (VUSBIN) to 0 to minimize current drain, even if SWBST and/or VUSB are disabled.

In a typical application, an ambient light sensor is connected here. A second general purpose input ADIN7B is available on channel 7. This input is muxed on the GPO4 pin. In the application, a second ambient light sensor is supposed to be connected here. TSX1 AND TSX2, TSY1 AND TSY2 Note: The TS[xy] [12] inputs must not exceed BP or VCORE.

FUNCTIONAL DEVICE OPERATION FUNCTIONAL DEVICE OPERATION PROCESSOR LOGIC INTERFACING CLOCK GENERATION A system clock is generated for internal digital circuitry as well as for external applications utilizing the clock output pins. A crystal oscillator is used for the 32.768 kHz time base and generation of related derivative clocks. If the crystal oscillator is not running (for example, if the crystal is not present), an internal 32 kHz oscillator will be used instead. Support is also provided for an external Secure Real Time Clock (SRTC), which may be integrated on a companion system processor IC. For media protection in compliance with Digital Rights Management (DRM) system requirements, the CLK32KMCU can be provided as a reference to the SRTC module, where tamper protection is implemented. The internal 32kHz oscillator is an integrated backup for the crystal oscillator and provides a 32.768 kHz nominal frequency at 20% accuracy if running. The internal oscillator only runs if a valid supply is available at BP and would not be used as long as the crystal oscillator is active. In absence of a valid supply at the BP supply node (for instance due to a dead battery), the crystal oscillator continues running supplied from the coin cell battery until the coin cell is depleted. All control functions will run off the crystal derived frequency, occasionally referred to as “32 kHz” for brevity’s sake. The crystal oscillator has been optimized for use in conjunction with the Micro Crystal CC7V-T1A32.768 kHz-9.0 pF-30 ppm or equivalent (such as the Micro Crystal CC5V-T1A or Epson FC135) is capable of handling its parametric variations. The electrical characteristics of the 32 kHz crystal oscillator are given in Tables 4 and 6, taking into account the crystal characteristics noted previously. The oscillator accuracy depends largely on the temperature characteristics of the used crystal. Application circuits can be optimized for required accuracy by adapting the external crystal oscillator network (via component accuracy and/or tuning). Additionally, a clock calibration system is provided to adjust the 32,768 cycle counter that generates the 1.0 Hz timer and RTC registers; see the RTC section for more detail. by connecting an open drain NMOS driver to the PWRON pin of 13892 so that it is in effect a parallel path for the power key. The 13892 will not be able to discern the turn on event from a normal power key initiated turn on, but the processor should have the knowledge since the RTC initiated turn on is generated locally. The VSRTC regulator provides the CLK32KMCU output level. It is also used to bias the Low Power SRTC domain of the SRTC module integrated on certain FSL processors. The VSRTC regulator is enabled as soon as the RTCPORB is detected. The VSRTC cannot be disabled. VSRTC REAL TIME CLOCK A Real Time Clock (RTC) is provided with time and day counters as well as an alarm function. The RTC utilizes the 32.768 kHz crystal oscillator for the time base, and is powered by the coin cell backup supply when BP has dropped below operational range. In configurations where the SRTC is used, the RTC can be disabled to conserve current drain by setting the RTCDIS bit to a 1 (defaults on at power up). TIME AND DAY COUNTERS The 32.768 kHz clock is divided down to a 1.0 Hz time tick which drives a 17 bit Time Of Day (TOD) counter. The TOD counter counts the seconds during a 24 hour period from 0 to 86,399 and will then roll over to 0. When the roll over occurs, it increments the 15 bit DAY counter. The DAY counter can count up to 32767 days. The 1.0 Hz time tick can be used to generate a 1.0 Hz interrupt if unmasked. TIME OF DAY ALARM A Time Of Day Alarm (TODA) function can be used to turn on the application and alert the processor. If the application is already on, the processor will be interrupted. The TODA and DAYA registers are used to set the alarm time. When the TOD counter is equal to the value in TODA and the DAY counter is equal to the value in DAYA, the TODAI interrupt will be generated. TIMER RESET SRTC SUPPORT AND VSRTC When configured for DRM mode (SPI bit DRM=1), the CLK32KMCU driver will be kept enabled through all operational states to ensure that the SRTC module always has its reference clock. If DRM=0, the CLK32KMCU driver will not be maintained in the Off state. It is also necessary to provide a means for the processor to do an RTC initiated wake-up of the system if it has been programmed for such capability. This can be accomplished As long as the supply at BP is valid, the real time clock will be supplied from VCORE. If not, it can be backed up from a coin cell via the LICELL pin. When the backup voltage drops below RTCUVDET, the RTCPORB reset signal is generated and the contents of the RTC will be reset. Additional registers backed up by coin cell will also reset with RTCPORB. To inform the processor that the contents of the RTC are no longer valid due to the reset, a timer reset interrupt function is implemented with the RTCRSTI bit. 13892 48 Analog Integrated Circuit Device Data Freescale Semiconductor Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not available from Freescale for import or sale in the United States prior to September 2010: MC13892VK and MC13892VL in 139, 186 MAPBGA packages. FUNCTIONAL DEVICE OPERATION COIN CELL BATTERY BACKUP The LICELL pin provides a connection for a coin cell backup battery or supercap. If the main battery is deeply discharged, removed, or contact-bounced (i.e., during a power cut), the RTC system and coin cell maintained logic will switch over to the LICELL for backup power. A small capacitor should be placed from LICELL to ground under all circumstances. Coin cells can get damaged and their lifetime reduced when deeply discharged. In order to avoid this, the internal circuitry supplied from LICELL is disconnected for voltages below the coin cell disconnect threshold. This will also cause the ADC reading of the coin cell voltage to yield zero. The coin cell charger circuit will function as a currentlimited voltage source, resulting in the CC/CV taper characteristic typically used for rechargeable Lithium-Ion batteries. The coin cell voltage is programmable from 2.5 to 3.3 V in 0.1 V steps, excepting 2.6 V. The coin cell charger voltage is programmable in the ON state where the charge current is fixed at ICOINHI. When the device is working in any of the low Power Off modes, the coin cell charger will also go into a low power mode in which the current it supplies to the coin cell will be reduced in order to save power.

The majority of registers are accessed through an SPI interface in a typical application. The same register set may be alternatively accessed with an I2C interface that is muxed on SPI pins. The following table describes the muxed pin options for the SPI and I2C interfaces.

FUNCTIONAL DEVICE OPERATION SPI INTERFACE I2C INTERFACE The IC contains a SPI interface port which allows access by a processor to the register set. Via these registers, the resources of the IC can be controlled. The registers also provide status information about how the IC is operating as well as information on external signals. The SPI port utilizes 32-bit serial data words comprised of 1 write/read_b bit, 6 address bits, 1 null bit, and 24 data bits. The addressable register map spans 64 registers of 24 data bits each. When configured for I2C mode, the interface may be used to access the complete register map. Since SPI configuration is more typical, references within this document will generally refer to the common register set as a “SPI map” and bits as “SPI bits”. However, it should be understood that access reverts to I2C mode when configured as such. The SPI pins CLK and MISO are reused for the SCL and SDA lines respectively. Selection of I2C mode for the interface is configured by hardwiring the CS pin to VCORE on the application board. Table 14. Muxed Pin Options for SPI and I2C Interfaces (I2C Functions) PIN NAME I2C Mode Functionality CS Configuration(53) CLK SCL: I2CBUS clock MISO SDA: Bi-directional serial data line MOSI A0 Address Selection(54) Notes 53. CS tied to VCORE at Cold Start configures interface for I2C mode; the pin is not used in I2C mode other than for configuration. 54. In I2C mode, the MOSI pin hard wired to ground or VCORE is used to select between two possible addresses. The I2C mode of the interface is implemented generally following the Fast Mode definition, which supports up to 400 kbits/s operation. (exceptions to the standard are noted to be 7-bit only addressing and no support for General Call addressing). Timing diagrams, electrical specifications, and further details can be found in the I2C specification, which is available for download at: http://www.nxp.com/acrobat_download/literature/9398/ 39340011.pdf INTERRUPT CONTROL The system is informed about important events based on interrupts. Unmasked interrupt events are signaled to the processor by driving the INT pin high; this is true whether the communication interface is configured for SPI or I2C. Each interrupt is latched so that even if the interrupt source becomes inactive, the interrupt will remain set until cleared. Each interrupt can be cleared by writing a 1 to the appropriate bit in the Interrupt Status register. This will also cause the interrupt line to go low. If a new interrupt occurs while the processor clears an existing interrupt bit, the interrupt line will remain high. Each interrupt can be masked by setting the corresponding mask bit to a 1. As a result, when a masked interrupt bit goes high, the interrupt line will not go high. A masked interrupt can still be read from the Interrupt Status register. This gives the processor the option of polling for status from the IC. The IC powers up with all interrupts masked, so the processor must initially poll the device to determine if any interrupts are active. Alternatively, the processor can unmask the interrupt bits of interest. If a masked interrupt bit was already high, the interrupt line will go high after unmasking. Interrupts generated by external events are debounced; therefore, the event needs to be stable throughout the debounce period before an interrupt is generated. Nominal debounce periods for each event are documented in the INT summary table following later in this chapter. Due to the asynchronous nature of the debounce timer the effective debounce time can vary slightly. 13892 50 Analog Integrated Circuit Device Data Freescale Semiconductor Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not available from Freescale for import or sale in the United States prior to September 2010: MC13892VK and MC13892VL in 139, 186 MAPBGA packages. FUNCTIONAL DEVICE OPERATION SUPPLIES A system power scheme for portable devices is provided which includes both switching and linear regulators. Various operational modes are available for the power circuitry, which may be accessible through SPI programming and the state of the STANDBY pins. Programmable Standby mode configuration allows automated system level control to optimize quiescent efficiency without the need for or latency of SPI intervention. The switch mode supply subsystem include a core block for clock generation, 4 step down (buck) switching regulators and two step up (boost) switching regulators. Linear regulators are provided for key power domains not supplied directly by switching regulators or the battery. Pass devices are integrated for most regulators for board area and cost advantages. External PNP pass devices are used selectively to help manage internal power dissipation. A general application of the power tree is illustrated in the Figure 6 diagram. Supply names are suggestive of typical applications, but not restrictive. Figure 6.

FUNCTIONAL DEVICE OPERATION Figure 7. Buck Switch Diagram The Buck switcher topology includes an integrated (DVS) by using SPI driven voltage steps, state machine synchronous rectifier, meaning that the rectifying diode is defined modes, and direct DVSx pin control. SW1 and SW2 implemented on chip as a low ohmic FET. The placement of also include the Switcher Increment/Decrement (SID) an external diode is therefore not required, but overall feature, with which, an increment command will increase the switcher efficiency may benefit from this. The buck set point voltage by a single 25 mV step, and a decrement command will decrease it in the same amount of voltage. The converters permit a 100% duty cycle operation. transition time for the step will be the same as programmed During normal operation several power modes are for the DVS feature. Maximum and minimum voltages are possible, depending on the loading. For medium and full programmable to ensure the switcher voltage does not go out loading, synchronous PWM control is the most efficient while a specific range. Panic mode is also included to quickly return maintaining a constant switching frequency. the switcher voltage to its normal programmed set point. The output voltages of the buck switchers are SPI When initially activated, switcher outputs will apply configurable and two output ranges are available, individually controlled stepping to the programmed value. The soft start programmed with SWxHI for SW2, SW3, and SW4 bucks, feature limits the inrush current at startup. SW1 is limited to only one output range. Presets are available Point of Load feedback is intended for minimizing errors for both the Normal and Standby operation. due to board level IR drops. The first voltage range that applies for all the Buck switchers goes from 0.6 to 1.375 V in 25 mV steps. The MODES OF OPERATION second one does not apply for SW1 and goes from 1.1 to 1.85 V also in 25 mV steps. Two PWM modes are available: SW1 and SW2 include pin controlled Dynamic Voltage PWM-NPS: sacrifices low load efficiency for a continuous Scaling (DVS) operation. When transitioning from one switching operation. voltage to another, the output voltage slope is controlled in PWM-PS: offers better low load efficiency by allowing the steps of 25 mV per time step (time step as defined for DVS absence of switching cycles at low output loading. This pulse stepping for SW1 and SW2, fixed at 4.0 μs for SW3, and SW4). This allows for support of dynamic voltage scaling 13892 52 Analog Integrated Circuit Device Data Freescale Semiconductor Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not available from Freescale for import or sale in the United States prior to September 2010: MC13892VK and MC13892VL in 139, 186 MAPBGA packages. FUNCTIONAL DEVICE OPERATION skipping feature improves efficiency by reducing dynamic switching losses simply by switching less often. In its lowest power mode, the switcher can regulate using hysteresis control known as a Pulse Frequency Modulation (PFM) control scheme. The frequency spectrum will be a function of input and output voltage, loading, and the external components. Due to its spectral variance and lighter drive capability, PFM mode is generally reserved for non-active radio modes and Deep Sleep operation. CURRENT LIMITER A built in current limiter ensures that during normal operation the maximum current through the coil is not exceeded (refer to Electrical Characteristics). This current limiter can be disabled by SPI bits. SWITCHING FREQUENCY A PLL generates the switcher system clocking from the 32.768 kHz crystal oscillator reference. To allow for spectral optimization for reduction of spurious influence in a radion environment, the PLL can be programmed via SPI from a multiplication factor of 84 to 105, in steps of 3. BOOST CONVERTERS SWBST SWBST is a boost switching regulator with a fixed 5.0 V output. It runs at 2/3 of the switcher PLL frequency. SWBST supplies the VUSB regulator for the USB system in OTG mode, as well as the VBUS voltage at the UVBUS pin. When SWBST is configured to supply the UVBUS pin in OTG mode, the feedback will be switched to sense the UVBUS pin instead of the SWBSTFB pin. Therefore, when driving the VBUS for OTG mode, the output of the switcher may rise to 5.75 V to compensate for the voltage drops in the internal switches. Note that the parasitic leakage path for a boost switcher will cause the output voltage SWBSTOUT and SWBSTFB to sit at a Schottky drop below the battery voltage, whenever SWBST is disabled. The switching NMOS transistor is integrated on-chip. An external fly back Schottky diode, inductor, and capacitor are required. Figure 8. 13892 SWBST Block Diagram. 13892 Analog Integrated Circuit Device Data Freescale Semiconductor 53 Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not available from Freescale for import or sale in the United States prior to September 2010: MC13892VK and MC13892VL in 139, 186 MAPBGA packages. FUNCTIONAL DEVICE OPERATION Main characteristics of SWBST are summarized in Tables 4 and 6. SWLED The supply to the serial LEDs is provided by an inductive boost switcher as illustrated in Figure 9. The boost converter is automatically enabled when one or more backlight drivers are enabled. sense resistor which creates a drop that is then compared to a fixed voltage. The output of the comparator is the flag of over-current in the output driver of the boost converter. When an over-current is detected, the PWM cycle is stopped by turning off the internal NMOS, which allows the current in the coil to decrease. Over-voltage Protection The boost converter contains a two phase over-voltage detection to prevent the SWLEDOUT from rising higher than 28V. LDOS Figure 9. The boost converter output voltage is adapted automatically to the load such that the headroom on the active LED drivers is maintained at a sufficient level (output voltage range from BP to 25.5 V). This allows for a very efficient backlighting scheme. The control is time continuous. When accounting for the diode drop and the driver headroom, the total available supply for the LEDs will be sufficient for up to 6 white LEDs in series. The boost converter runs at 2/3 of the switcher PLL generated frequency. PROTECTION FUNCTIONS The following is a description of the linear regulators. For convenience these regulators are named to indicate their typical or possible applications, but the supplies are not limited to these uses, and may be applied to any loads within the specified regulator capabilities. A low power standby mode controlled by STANDBY is provided in which the bias current is aggressively reduced. This mode is useful for deep sleep operations, where certain supplies cannot be disabled, but active regulation can be tolerated with lesser parametric requirements. The output drive capability and performance are limited in this mode. Apart from the integrated linear regulators, there are also GPO output pins provided to enable and disable discrete regulators or functional blocks, or to use as general purpose outputs for any system need. For example, one application may be to enable a battery pack thermistor bias in synchronization with timed ADC conversions. All regulators use the main bandgap as the reference. The main bandgap is bypassed with a capacitor at REFCORE. The bandgap and the rest of the core circuitry is supplied from VCORE. The performance of the regulators is directly dependent on the performance of VCOREDIG and the bandgap. No external DC loading is allowed on VCOREDIG or REFCORE. VCOREDIG is kept powered as long as there is a valid supply and/or coin cell. The following table captures the main characteristics of the core circuitry. Current Limit SWBST has an over-current limit protection of 1.5 A. A portion of the output current is sensed across an internal 13892 54 Analog Integrated Circuit Device Data Freescale Semiconductor Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not available from Freescale for import or sale in the United States prior to September 2010: MC13892VK and MC13892VL in 139, 186 MAPBGA packages.

The core is in On mode when charging, or when the state machine of the IC is not in the Off mode, nor in the power cut mode. Otherwise, the core is in Off mode. The transient load and line response are specified with the waveforms as depicted in Figure 10. Note that where the transient load response refers to the overshoot only, so excluding the DC shift itself, the transient line response refers to the sum of both overshoot and DC shift. This is also valid for the mode transition response. 13892 Analog Integrated Circuit Device Data Freescale Semiconductor 55 Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not available from Freescale for import or sale in the United States prior to September 2010: MC13892VK and MC13892VL in 139, 186 MAPBGA packages. FUNCTIONAL DEVICE OPERATION Figure 10. Transient Response Waveforms VAUDIO AND VVIDEO SUPPLIES The primary applications of these power supplies are for audio, and TV-DAC. These supplies could also be used for other peripherals if one of these functions is not required. Low Power modes and programmable Standby options can be used to optimize power efficiency during deep sleep modes. VAUDIO is implemented with an integrated PMOS pass FET and has a dedicated input supply pin VINAUDIO. The nominal output voltage (VNOM as referred in Table Table 4) of VVIDEO can go from 2.5 to 2.7 V on 0.1 V steps, it also can be programmed to be 2.775 V. Its output current depends on the external pass device. The nominal output voltage (VNOM as referred in Table Table 4) of VAUDIO can be programmed to be 2.3, 2.5, 2.775 or 3.0 V. LOW VOLTAGE SUPPLIES protocol and peripheral needs. Depending on the lineup and power requirements, these supplies may be considered for sharing with other loads, but noise injection must be avoided and filtering added if necessary, to ensure suitable PLL performance. The VDIG and VPLL regulators have a dedicated input supply pin: VINDIG for the VDIG regulator and VINPLL for the VPLL regulator. VINDIG and VINPLL can be connected to either BP or a 1.8 V switched mode power supply rail such as from SW4 for the two lower set points of each regulator (1.2 V and 1.25 V output for VPLL and 1.05 and 1.25 V output for VDIG). In addition, when the two upper set points are used (1.50 V and 1.8 V output for VPLL and 1.65 V and 1.8 V for VDIG) can be connected to either BP or a 2.2 V nominal external switched mode power supply rail to improve power dissipation. The nominal programmable output voltage of VPLL (VNOM as referred in Table 4) could be 1.2, 1.25, 1.50 or 1.8 V, while VDIG can be configured to 1.05, 1.25, 1.65 and 1.8 V. VDIG and VPLL are provided for isolated biasing of the Baseband system PLLs for clock generation in support of 13892 56 Analog Integrated Circuit Device Data Freescale Semiconductor Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not available from Freescale for import or sale in the United States prior to September 2010: MC13892VK and MC13892VL in 139, 186 MAPBGA packages. FUNCTIONAL DEVICE OPERATION PERIPHERAL INTERFACING USB SUPPLY IC interfaces in the lineups generally fall in two categories: low voltage IO primarily associated with the AP IC and certain peripherals at the SPIVCC level (powered from SW4), and a higher voltage interface level associated with other peripherals not compatible with the 1.8 V SPIVCC. VIOHI is provided at a fixed nominal output voltage 2.775 V level (VNOM as referred in Table 4) for such interfaces, and may also be applied to other system needs within the guidelines of the regulator specifications. The input VINIOHI is not only used by the VIOHI regulator, but also by other blocks. Therefore it should always be connected to BP, even if the VIOHI regulator is not used by the system. VIOHI has an internal PMOS pass FET which will support loads up to 100 mA. The VUSB regulator is used to supply a nominal output voltage (VNOM as referred in Table 4) of 3.3 V to the external USB PHY. The UVBUS line of the USB interface is supplied by the host, in the case of host mode operation, or by the integrated VBUS generation circuit, in the case of USB OTG mode operation. The VBUS circuit is powered from the SWBST boost supply, to ensure OTG current sourcing compliance through the normal discharge range of the main battery. The VUSB regulator can be supplied from the VBUS wire of the USB cable (power rail of the USB cable), when supplied by a host, in the case of host mode operation, or by the SWBST voltage for OTG mode operation. The SWBST voltage supplies the VUSB regulator from the VINUSB pin, which is internally connected to SWBST, and also to the UVBUS pin to drive the VBUS on this mode (as long as VBUSEN pin is logic high =1). When UVBUS/CHARGRAW is detected in host mode, the USB regulators, VUSB and VUSB2 should be automatically enabled. It will be up to the processor to determine what type of device is connected, either a USB host or a wall charger, and take appropriate action. The VUSB and VUSB2 regulators can be enabled independent of OTG or Host Mode by setting the individual SPI enable bits, VUSBEN and VUSB2EN respectively. Since UVBUS can be shared with the charger input at the board level, the UVBUS node must be able to withstand the same high voltages as the charger. In over-voltage conditions, the VUSB regulator is disabled. USB supplies characteristics are shown in Tables 4 and 6. Note: When VUSBIN =1 , UVBUS will be connected via internal switches to VINUSB and incur some current drain on that pin, as much as 270 μA maximum, so care must be taken to disable this path and set this SPI bit (VUSBIN) to 0 to minimize current drain, even if SWBST and/or VUSB are disabled. CAMERA The camera module is supplied by the regulator VCAM. This allows for powering the entire module independent of the rest of other parts of the system, as well as to select from a number of VCAM output levels for camera vendor flexibility. In applications with a dual camera, it is anticipated that only one of the two cameras is active at a time, allowing the VCAM supply to be shared between them. VCAM has an internal PMOS pass FET, which will support up to 2Mpixel Camera modules (<65 mA). To support higher resolution cameras, an external PNP is provided. The external PNP configuration is offered to avoid excess on-chip power dissipation at high loads and large differential between BP and output settings. For lower current requirements, an integrated PMOS pass FET is included. The input pin for the integrated PMOS option is shared with the base current drive pin for the PNP option. The nominal output voltage of this regulator (VNOM as referred in Table 4) is SPI configurable, and can be 2.5, 2.6, 2.75, or 3.0 V. The output current when working with the internal pass FET is 65 mA, and could be up to 250 mA when working with an external PNP. MULTI-MEDIA CARD SUPPLY This supply domain is generally intended for user accessible multi-media cards such as Micro-SD (TransFlash), RS-MMC, and the like. An external PNP is utilized for this LDO to avoid excess on-chip power dissipation at high loads and large differential between BP and output settings. The external PNP device is always connected to the BP line in the application. VSD may also be applied to other system needs within the guidelines of the regulator specifications. At the 1.8 V set point, the VSD regulator can be powered from and external buck switcher (2.2 V typ) for an efficiency advantage and reduced power dissipation in the pass devices. This regulator can be configured for nominal output voltages (VNOM as referred in Table 4) of 1.8, 2.00, 2.60, 2.70, 2.8, 2.9, 3.00, and 3.15 V. All of these configurations can draw a current of 250 mA. VUSB REGULATOR VUSB2 is implemented with an integrated PMOS pass FET and has a dedicated supply pin VINUSB2. The pin VINUSB2 should always be connected to BP, even in case the regulators are not used by the application. The nominal output voltage of this regulator (VNOM as referred in Table 4) can be programmed to be 2.400, 2.600, 2.700, and 2.775 V with a load capability of 50 mA. GEN1, GEN2 AND GEN3 REGULATORS General purpose LDOs VGEN1, VGEN2, and VGEN3 are provided for expansion of the power tree, to support peripheral devices which could include WLAN, BT, GPS, or other functional modules. All the regulators include programmable set points for system flexibility. At the 1.2 V and 1.5 V set points, both VGEN1 and VGEN2 can be powered from an external buck switcher (2.2 V typ), for an 13892 Analog Integrated Circuit Device Data Freescale Semiconductor 57 Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not available from Freescale for import or sale in the United States prior to September 2010: MC13892VK and MC13892VL in 139, 186 MAPBGA packages. FUNCTIONAL DEVICE OPERATION efficiency advantage and reduced power dissipation in the pass devices. VGEN1 nominal output voltage (VNOM as referred in Table 4) can be 1.20, 1.50, 2.7775, or 3.15 V, and has a capability of 200 mA. VGEN2 is configurable for 1.20, 1.50, 1.60, 1.80, 2.70, 2.80, 3.00, and 3.15 V, and can supply up to 350 mA. VGEN3 has an internal PMOS pass FET, which will support loads up to 50 mA. For higher current capability, drive for an external PNP is provided. The external PNP configuration is offered to avoid excess on-chip power dissipation at high loads and large differential between BP and output settings. The input pin for the integrated PMOS option is shared with the base current drive pin for the PNP option. This regulator is configurable for nominal output voltages (VNOM as referred in Table 4) of 1.80 and 2.90 V with a capability of 200 mA when working with an external PNP. GENERAL PURPOSE OUTPUTS The GPO drivers included can provide useful system level signaling with SPI enabling and programmable Standby control. Key use cases for GPO outputs include battery pack thermistor biasing and enabling of peripheral devices, such as light sensor(s), camera flash, or even supplemental regulators. SPI enabling can be used for coordinating GPOs with ADC conversions for consumption efficiency and desired settling characteristics. The GPO1 output is intended to be used for battery thermistor biasing. For accurate thermistor reading by the ADC, the output resistance of the GPO1 driver is of importance. Finally, a muxing option is included to allow GPO4 to be configured for a muxed connection into Channel 7 of the GP ADC. As an example for a dual light sensor application, Channel 7 can be toggled between the ADIN7 (ADINSEL7=00) and GPO4 (ADINSEL7=11), for convenient connectivity and monitoring of two sensors. The GPO4 pin is configured for ADC input mode by default (GPO4ADIN=1), so that the GPO driver stage is at high impedance at power up. The GPO4 pin can be configured by software for GPO operation with GPO4ADIN=0.

The short-circuit protection (SCP) system includes debounced fault condition detection, regulator shutdown, and processor interrupt generation to contain failures and minimize chance of product damage. If a short-circuit condition is detected, the LDO will be disabled by resetting its VxEN bit while at the same time an interrupt SCPI will be generated to flag the fault to the system processor. BATTERY MANAGEMENT The 13892 supports single path and serial path charging. In single path charging, the device is always supplied from the battery and therefore always has to be present and valid. In a serial path charging scheme, the device may operate directly from the charger while the battery is removed or deeply discharged. The charger supports charging from a USB host or a wall charger. The charger interface provides linear operation via an integrated DAC at programmable current levels. It incorporates a standalone trickle charge mode, in case of a dead battery with dual LED indicator driver. Over-voltage, short-circuit, and under-voltage detectors are included as well as charger detection and removal. The charger includes the necessary circuitry to allow for USB charging and for reverse supply to an external accessory. The battery management system also provides a battery presence detector, and an A to D converter that serves for measuring the charge current, battery and other supply voltages, as well as for measuring the battery thermistor and die temperature. Finally, a system is included for monitoring the current drawn from, or charged into the main battery for support of a Coulomb Counter function. 13892 58 Analog Integrated Circuit Device Data Freescale Semiconductor Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not available from Freescale for import or sale in the United States prior to September 2010: MC13892VK and MC13892VL in 139, 186 MAPBGA packages.

In order to charging a dead battery. support dead battery operation, a so called “serial path” charging configuration including M3 needs to be used. Then COMPARATORS in case of a dead battery, the transistor M3 is made nonThe charger detection is based on three comparators.

For all but the lowest current setting, a charger removal The UVBUS pin must be shorted to CHRGRAW in cases is detected, based on both the “charger presence” where the charger is being supplied from the USB cable.

The battery current monitoring resistor R1 and the comparators play a role in battery charging. These charge LED indicator are optional. comparators are “BATTMIN”, which monitors BATT for the safe charging battery voltage, “BATTON”, which monitors CHARGE PATH REGULATOR BATT for the safe operating battery voltage, and M1 and M2 are permanently used as a combined pass “BATTCYCL”, which monitors BPSNS for the constant device for a super regulator, with a programmable output current to constant voltage transition.

FUNCTIONAL DEVICE OPERATION CHARGE LED INDICATOR Since normal LED control via the SPI bus is not always possible in the standalone operation, a current sink is provided at the CHRGLED pin. The driver at CHRGLED serves as the trickle (sign of life) LED and will be activated when standalone charging is started, and will remain on also when the device is powered on, until the charger is programmed by SPI. MODES OF OPERATION REVERSE SUPPLY MODE The battery voltage can be applied to an external accessory via the charge path. The path is only established if the normal charge path is disabled. The turn on of M1 and M2 is intentionally slow. The current through the accessory supply path is monitored via the charge path sense resistor R2. It can be read out via the ADC. The accessory supply path is disabled and an interrupt CHGSHORTI is generated when the slow threshold or the fast threshold is crossed. The reverse path is disabled when a current reversal occurs, and an interrupt CHREVI is generated. This function operates up to 40°C. PROTECTION FUNCTIONS OVER-VOLTAGE PROTECTION In order to protect the application, the voltage at the CHRGRAW pin is monitored. When crossing the threshold (16 V high to low and low to high), the charge path regulator will be turned off by opening the mosfets connected to pins CHRGCTRL1 and CHRGCTRL2. An interrupt CHGFAULTI is generated with the associated CHGFAULTM mask bit. In order to ensure immediate protection, the control of M1, M2, and M3 occurs in real time. The UVBUS pin is also protected against over-voltages. This will occur at much lower levels then for CHRGRAW. When a VBUS over-voltage is detected the internal circuitry of the USB block is disconnected. An USBOVI is generated in this case. When the maximum voltage of the IC is exceeded, damage will occur to the IC, and the state of the mosfets connected to pins CHRGCTRL1 and CHRGCTRL2 cannot be guaranteed. If one wants to protect against these failure conditions, additional protection will be required. The same is valid for charger polarity inversion protection. OVER-POWER DISSIPATION PROTECTION STANDALONE CHARGING A standalone charge mode of operation is provided to minimize software interaction. It also allows that a completely discharged battery can be revived without processor control. This is especially important when charging from a USB host or when the optional transistor M3 is not placed. SOFTWARE CONTROLLED CHARGING The charger can also be operated under software control. In this mode, full control of the charger settings is assumed by software; the state machine will no longer determine the mode of charging. FACTORY MODE In factory mode, power is provided to the application with no battery present. It is not a situation which should occur in the field. The factory mode is differentiated from a USB Host by, in addition to a valid VBUS, a UID being pulled high to VBUS level during the attach, See Connectivity (USB Interface) on page 63. USB LOW POWER BOOT USB low power boot allows the application to boot with a dead battery within the 100 mA USB budget, until the processor has negotiated for the full current capability. This mode expedites the charging of the dead battery and allows the software to bring up the LCD display screen with the message “Charging battery”. Since the charge path operates in a linear fashion, the dissipation can be significant and care must be taken to ensure that the external pass FETs M1 and M2 are not over dissipating when charging. By default, the charge system will protect against this by a built in power limitation circuit.This circuit will monitor the voltage drop between CHRGRAW and CHRGISNS, and the current through the external sense resistor connected between CHRGISNS and BPSNS. When required, a duty cycle is applied to the FETs connected on CHRGCTRL1 and CHRGCTRL2, and thus the charge current, in order to stay within the power budget. At the same time the FET connected to BATTFET pin is forced to conduct to keep the application powered. In case of excessive supply conditions, the power limiter minimum duty cycle may not be sufficiently small to maintain the actual power dissipation within budget. In that case, the charge path will be disabled and the CHGFAULTI interrupt generated. The power budget can be programmed by the SPI through the PLIM[1:0] bits, which establishes a power limit from 600 to 1200 mW in 200 mV steps. The power dissipation limiter can be disabled by setting the PLIMDIS bit. In this case, it is advised to use close software control to estimate the dissipated power in the external pass FETs. The power limiter is automatically disabled in serial path factory mode and in reverse mode. Since a charger attachment can be a Turn On event when a product is initially in the Off state, any nondefault settings that are intended for PLIM[1:0] and PLIMDIS should be programmed early in the configuration sequence to ensure proper supply conditions adapted to the application. To avoid any false detection during power up, the power limiter output is blanked at the start of the charge cycle. As a safety 13892 60 Analog Integrated Circuit Device Data Freescale Semiconductor Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not available from Freescale for import or sale in the United States prior to September 2010: MC13892VK and MC13892VL in 139, 186 MAPBGA packages. FUNCTIONAL DEVICE OPERATION precaution, the power dissipation is monitored and the desired duty cycle is estimated. When this estimated duty cycle falls below the power limiter minimum duty cycle, the charger circuit will be disabled. ADC SUBSYSTEM The ADC core is a 10 bit converter. The ADC core and logic run on 2/3 of the switcher PLL generated frequency, so approximately 2.0 MHz. If an ADC conversion is requested while the PLL is not active, it will be automatically enabled by the ADC. A 32.768 kHz equivalent time base is derived from the 2.0 MHz clock to time ADC events. The ADC is supplied from VCORE. The ADC core has an integrated auto calibration circuit which reduces the offset and gain errors. The switcher PLL is programmable, so when the switcher frequency is changed, the frequency applied to the ADC converter will change accordingly. Although the conversion time is inversely proportional to the PLLX[2:0] setting, this will not influence the ADC performance. The locally derived 32.768 kHz will remain constant in order to not influence the different timings depending on this time base. The ADC Subsystem has 8 channels: Channel 0 Battery Voltage: The battery voltage is read at the BATT pin at channel 0. Channel 1 Battery Current: The current flowing out of and into the battery can be read via the ADC by monitoring the voltage drop over the sense resistor between BATT and BATTISNSCC. Channel 2 Application Supply: The application supply voltage is read at the BP pin at channel 2. Channel 3 Charger Voltage: The charger voltage is measured at the CHRGRAW pin at channel 3. Channel 4 Charger Current: The charge current is read by monitoring the voltage drop over the charge current sense resistor. This resistor is connected between CHRGISNS and BPSNS. Channel 5 ADIN5, Battery Thermistor and Battery Detect: On channel 5, ADIN5 may be used as a general purpose input, but in a typical application, ADIN5 is used to read out the battery pack thermistor. The thermistor will have to be biased with an external pull-up to a voltage rail greater than the ADC input range. In order to save current when the thermistor reading is not required, it can be biased from one of the general purpose IOs such as GPO1. A resistor divider network should assure the resulting voltage falls within the ADC input range, especially when the thermistor check function is used. When the application is on and supplied by the charger, a battery removal can be detected by a battery thermistor presence check. When the thermistor terminal becomes high-impedance, the battery is considered being removed. This detection function is available at the ADIN5 input. Channel 6 ADIN6 and Coin Cell Voltage: On channel 6, ADIN6 may be used as a general purpose unscaled input but in a typical application, the PA thermistor is connected here. In addition, on channel 6, the voltage of the coin cell connected to the LICELL pin can be read. Channel 7 ADIN7 and ADIN7B, UID and Die Temperature: On channel 7, ADIN7 may be used as a general purpose input. In a typical application, an ambient light sensor is connected here. A second general purpose input ADIN7B is available. In the application, a second ambient light sensor is supposed to be connected here. In addition, on channel 7, the voltage of the USB ID line connected to the UID pin and the die temperature can be read. COULOMB COUNTER As discussed previously, the current into and from the battery can be read out through the general purpose ADC as a voltage drop over the R1 sense resistor. Together with the battery voltage reading the battery capacity can be estimated. A more accurate battery capacity estimation can be obtained by using the integrated Coulomb Counter. The Coulomb Counter (or CC) monitors the current flowing in/out of the battery by integrating the voltage drop across the battery current sense resistor R1, followed by an A to D conversion. The result of the A to D conversion is used to increase/decrease the contents of a counter that can be read out by software. 13892 Analog Integrated Circuit Device Data Freescale Semiconductor 61 Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not available from Freescale for import or sale in the United States prior to September 2010: MC13892VK and MC13892VL in 139, 186 MAPBGA packages. FUNCTIONAL DEVICE OPERATION Figure 12. 13892 Coulomb Counter Block Diagram. PROTECTIONS AGAINST FAULT CONDITIONS Counter roll over: CCOUT[15:0]=8000HEX This occurs when the contents of CCOUT[15:0] go from a negative to a positive value or vice versa. Software may interpret incorrectly the battery charge by this change in polarity. When CCOUT[15:0] becomes equal to 8000HEX the CCFAULT is set. The counter stays counting so its contents can still be exploited. Battery removal: ‘BP<UVDET’ When removing and replacing the battery, the contents of the counter are no longer valid. A battery removal is characterized by the input supply to the IC dropping below the under-voltage detect threshold, so BP<UVDET. To avoid false detection due to short power cuts, the CCFAULT is set only after a long debounce of 1.0 second. screen X plate is connected to TSX1 and TSX2, while the Y plate is connected to TSY1 and TSY2. A local supply TSREF will serve as a reference. Several readout possibilities are offered. To perform touch screen readings, the processor will have to select the touch screen mode, program the delay between the conversions via the ATO and ATOX settings, trigger the ADC via one of the trigger sources, wait for an interrupt indicating the conversion is done, and then read out the data. In order to reduce the interrupt rate and to allow for easier noise rejection, the touch screen readings are repeated in the readout sequence. The reference for the touch screen is TSREF and is powered from VCORE. In touch screen operation, TSREF is a dedicated regulator that is to say, no other loads than the touch screen should be connected here. Table 17. 13892 Touch Screen ADC Readings Battery removal when charging: BATTDETBS=1 The battery removal detection as described previously is not applicable when charging, since in this case, the charger will continue to supply the application and the BP will not drop below UVDET. To still detect a battery removal, one can use the battery detect function, as described in ADC Subsystem on page 61. When the sense bit BATTDETBS becomes a 1, the CCFAULT is set only after a long debounce of 1.0 second. Touch Screen Interface The touch screen interface provides all circuitry required for the readout of a 4-wire resistive touch screen.

FUNCTIONAL DEVICE OPERATION The dummy conversion inserted between the different readings is to allow the references in the system to be prebiased for the change in touch screen plate polarity and will read out as ‘0’. MODES OF OPERATION In inactive mode, the inputs TSX1, TSX2, TSY1, and TSY2 can be used as general purpose inputs. They are respectively mapped on ADC channels 4, 5, 6, and 7. In interrupt mode, a voltage is applied to the X-plate (TSX2) via a weak current source to VCORE, while the Yplate is connected to ground (TSY1). When the two plates make contact both will be at a low potential. This will generate a pen interrupt TSI to the processor. This detection does not make use of the ADC core or the TSREF regulator, so both can remain disabled. In touch screen mode, the XY coordinate pairs and the contact resistance are read. The X-coordinate is determined by applying TSREF over the TSX1 and TSX2 pins while performing a high-impedance reading on the Y-plate through TSY1. The Y-coordinate is determined by applying TSREF between TSY1 and TSY2 while reading the TSX1 pin. The contact resistance is measured by applying a known current into the TSY1 terminal of the touch screen and through the terminal TSX2, which is grounded. The voltage difference between the two remaining terminals TSY2 and TSX1 is measured by the ADC, and equals the voltage across the contact resistance. Measuring the contact resistance helps in determining if the touch screen is touched with a finger or stylus. 42 mA respectively. This facilitates the current setting, in case two or more serial LED strings are connected in parallel to the same driver, or when using super bright LEDs. The boost switcher SWLED supplying the backlight LEDs is shared between all three backlight drivers. However, a maximum of only two backlight drivers can be activated at the same time, for instance the main display plus keypad. If all three backlight drivers are enabled meaning none of the duty cycles equals 0/32, then none of the drivers will be activated. SIGNALING LED DRIVERS The signaling LED drivers LEDR, LEDG, and LEDB are independent current sink channels. Each driver channel features programmable current levels from 0 to 21 mA as well as programmable PWM duty cycle settings. By a combination of level and PWM settings, each channel provides flexible LED intensity control. By driving LEDs of different colors, color mixing can be achieved. Blue LEDs or bright green LEDs require more headroom than red and normal green signal LEDs. In the application, a 5.0 V or equivalent supply rail is therefore required. This is provided by the integrated boost converter SWBST. As with the backlight driver channels, the signaling LED drivers include ramp up and ramp down patterns are implemented in hardware. In addition, programmable blink rates are provided. Blinking is obtained by lowering the PWM repetition rate of each of the drivers, while the on period is determined by the duty cycle setting. To avoid high frequency spur coupling in the application, the switching edges of the output drivers are softened." LED DRIVERS FOR LIGHTING SYSTEM BACKLIGHT LED DRIVERS The lighting system includes backlight drivers for main display, auxiliary display, and keypad. The backlight LEDs are configured in series and supplied from an inductive boost supply See Boost Converters on page 53. Three additional drivers are provided for RGB or general purpose signaling. Ramp up and ramp down patterns are implemented in hardware to reduce the burden of real time software control via the SPI, to orchestrate dimming and soft start lighting effects. These patterns are guaranteed by design. The current level is programmable in a low range mode and in a high range mode from 0 to 21 mA and from 0 to CONNECTIVITY (USB INTERFACE) The 13892 contains the regulators required to supply the PHY contained in the i.MX51, i.MX37, i.MX35, and i.MX27 processors. The regulators used to power the external PHY in the i.MX51 and i.MX37 are VUSB, VUSB2, and VUSB for the i.MX35 and i.MX27 processors. The IC also provides the 5.0 V supply for USB OTG operation. The USB interface may be used for portable product battery charging. Finally included are comparators/detectors for VBUS and ID detection. VBUS is the power rail of the USB cable that must be connected to the UVBUS pin. The USB interface is illustrated in Figure 13. 13892 Analog Integrated Circuit Device Data Freescale Semiconductor 63 Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not available from Freescale for import or sale in the United States prior to September 2010: MC13892VK and MC13892VL in 139, 186 MAPBGA packages. FUNCTIONAL DEVICE OPERATION Figure 13. 13892 USB Interface Block Diagram OTG MODE (ON THE GO) The ID detector is primarily used to determine if a mini-A or mini-B style plug has been inserted into a mini-AB style receptacle on the application. However, it also supports two additional modes which are outside of the USB standards: a factory mode, and a non-USB accessory mode. The state of the ID detection can be read via the SPI to poll dedicated sense bits for a floating, grounded, or factory mode condition on the UID pin. There are also dedicated maskable interrupts for each UID condition as well. Since portable applications have limited capabilities, this supplement to the USB2.0 specification was developed in order to allow a portable device to take the role of a USB host. In this mode of operation, SWBST is internally switched to Parameter supply the VUSB regulator, and SWBST will drive VBUS from the VUSBIN pin as long as VBUSEN pin is a logic high = 1. According to the USB2.0 specification, the USB host is the device where the USB Host Controller is installed, through which it interacts with the USB devices. The USB host is responsible for: • Detecting the attachment and removal of USB devices. • Managing control flow between the host and USB devices. • Managing data flow between the host and USB devices. • Collecting status and activity statistics. • Providing power to attached USB devices. When working in host mode, VUSB is supplied from the VBUS wire of the USB cable (VBUS).

The power control system interfaces with the processor via different IO signals and the SPI bus. It also uses on chip signals and detector outputs. Figure 14.

FUNCTIONAL DEVICE OPERATION OPERATIONAL MODES OPERATIONAL MODES The following are text descriptions of the power states of the system with additional details of the state machine to complement Figure 14. Note that SPI control is only possible in the Watchdog, On, and User Off Wait states, and that the interrupt line INT is kept low in all states except for Watchdog and On. OFF If the supply at BP is above the UVDET threshold, only the IC core circuitry at VCOREDIG and the RTC module are powered. All other supplies are inactive. To exit the Off mode, a valid turn on event is required. No specific timer is running in this mode. If the supply at BP is below the UVDET threshold, no turn on events are accepted. If a valid coincell is present, the core gets its power from LICELL. The only active circuitry is the RTC module, and the BP greater than UVDET detection. COLD START This is entered upon a Turn On event from Off, Warm Boot, successful PCUT, or Silent System Restart. The first 8.0 ms are used for initialization which includes bias generation, PUMS / configuration latching, and qualification of the input supply level BP. The switchers and regulators are then powered up sequentially to limit the inrush current. The reset signals RESETB and RESETBMCU are kept low. The Reset timer starts running when entering Cold Start. The input control pins WDI and STANDBYx are ignored. WATCHDOG The system is fully powered and under SPI control. RESETB and RESETBMCU are high. The Watchdog timer starts running when entering the Watchdog state. When expired, the system transitions to the On state, where WDI will be checked and monitored. The input control pins WDI and STANDBYx are ignored while in the Watchdog state. ON The system is fully powered and under SPI control. RESETB and RESETBMCU are high. The WDI pin must be high to stay in this mode. USER OFF WAIT The system is fully powered and under SPI control. The WDI pin no longer has control over the part. The Wait mode is entered by a processor request for User Off. The Wait timer starts running when entering User Off Wait mode. This leaves the processor time to suspend or terminate its tasks. MEMORY HOLD AND USER OFF (LOW POWER OFF STATES) As noted in the User Off Wait description, the system is directed into low power Off states, based on a SPI command in response to an intentional Turn Off by the end user. The only exit then will be a Turn On event. To an end user, the Memory Hold and User Off states look like the product has been shut down completely. However, a faster startup is facilitated by maintaining external memory in self-refresh mode (Memory Hold and User Off mode), as well as powering portions of the processor core for state retention (User Off only). MEMORY HOLD RESETB and RESETBMCU are low, and both CLK32K and CLK32KMCU are disabled (CLK32KMCU active if DRM is set). Upon a Turn On event, the Cold Start state is entered, the default power up values are loaded, and the MEMHLDI interrupt bit is set. A Cold Start out of the Memory Hold state will result in shorter boot times compared to starting out of the Off state, since software does not have to be loaded and expanded from flash. The startup out of Memory Hold is also referred to as Warm Boot. No specific timer is running in this mode. USER OFF RESETB is low and RESETBMCU is kept high. The 32 kHz peripheral clock driver CLK32K is disabled; CLK32KMCU (connected to the processor’s CKIL input) is maintained in this mode, if the CLK32KMCUEN and USEROFFCLK bits are both set, or if DRM is set. Any peripheral loading on SW1 and/or SW2 should be isolated from the output node(s) by the PWGT1 switch, which opens in both low power Off modes, due to the RESETB transition. In this way, leakage is minimized from the power domain, maintaining the processor core. Since power is maintained for the core (which is put into its lowest power state), and since MCU RESETBMCU does not trip, the processor’s state may be quickly recovered when exiting USEROFF upon a Turn On event. The CLK32KMCU clock can be used for very low frequency / low power idling of the core(s), minimizing battery drain while allowing a rapid recovery from where the system left off before the USEROFF command. Upon a Turn On event, Warm Start state is entered, and the default power up values are loaded. A Warm Start out of User Off will result in an almost instantaneous startup of the system, since the internal states of the processor were preserved along with external memory. No specific timer is running in this mode. WARM START Entered with a Turn On event from User Off. The first 8.0 ms is used for initialization which includes bias generation, PUMS latching, and qualification of the input 13892 66 Analog Integrated Circuit Device Data Freescale Semiconductor Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not available from Freescale for import or sale in the United States prior to September 2010: MC13892VK and MC13892VL in 139, 186 MAPBGA packages. FUNCTIONAL DEVICE OPERATION OPERATIONAL MODES supply level BP. The switches and regulators are then powered up sequentially to limit the inrush current. RESETB is kept low and RESETBMCU is kept high. CLK32KMCU is kept active if CLK32KMCU was set. The reset timer starts running when entering Warm Start. When expired, the Warm Start state is exited for the Watchdog state, a WARMI interrupt is generated, and RESETB will go high. INTERNAL MEMHOLD POWER CUT Power Cut description: When the supply at BP drops below the UVDET threshold due to battery bounce or battery removal, the Internal MemHold Power Cut mode is entered and a Power Cut (PCUT) timer starts running. The backup coin cell will now supply the RTC as well as the on chip memory registers and some other power control related bits. All other supplies will be disabled. Internal MemHold Power Cut: As previously described, a momentary power interruption will put the system into the Internal MemHold Power Cut state if PCUTs are enabled. The backup coin cell will now supply 13892’s core along with the 32 k crystal oscillator, the RTC system and coin cell backed up registers. All regulators and switchers will be shut down to preserve the coin cell and RTC as long as possible. Both RESETB and RESETBMCU are tripped, bringing the entire system down along with the supplies and external clock drivers, so the only recovery out of a Power Cut state is to reestablish power and initiate a Cold Start. POWER SAVING SYSTEM STANDBY A product may be designed to go into DSM after periods of inactivity, such as if a music player completes a play list and no further activity is detected, or if a gaming interface sits idle for an extended period. Two Standby pins are provided for board level control of timing in and out of such deep sleep modes. When a product is in DSM it may be able to reduce the overall platform current by lowering the switcher output voltage, disabling some regulators, or forcing GPOx low. This can be obtained by SPI configuration of the Standby response of the circuits along with control of the Standby pins. To ensure that shared resources are properly powered when required, the system will only be allowed into Standby when both the application processor (which typically controls the STANDBY pin) and peripherals (which typically control the STANDBYSEC pin) allow it—this is referred to as a Standby event. REGULATOR MODE CONTROL The regulators with embedded pass devices (VDIG, VPLL, VIOHI, VUSB, VUSB2, and VAUDIO) operate in two modes: a normal mode, and a low power mode. The transition between both modes occurs automatically, based on the load current. Therefore, no specific control is required to put these regulators in a low power mode (i.e., “On” implies an adaptive mode control” based on load current). Bits are reserved in case the automatic scheme shows to be insufficient. The regulators with external pass devices (VSD, VVIDEO, VGEN1, and VGEN2) can also operate in a normal and low power mode. However, since a load current detection cannot be performed for these regulators, the transition between both modes is not automatic, and is controlled by setting the corresponding mode bits for the operational behavior desired. The regulators VGEN3, and VCAM can be configured for using the internal pass device or external pass device as explained in LDOs on page 54. Therefore, depending on the configuration selected, the automatic low power mode is or is not available. BUCK SWITCHERS Operational modes of the Buck switchers can be controlled by direct SPI programming, altered by the state of the STANDBY pins, by direct state machine influence (i.e., entering Off or low power Off states, for example), or by load current magnitude when so configured. Available modes include PWM with No Pulse Skipping (PWM), PWM with Pulse Skipping (PWMPS), Pulse Frequency Mode (PFM), and Off. The transition between the two modes PWMPS and PFM can occur automatically based on the load current (auto). Therefore, no specific control is required to put the switchers in a low power mode. When the buck switchers are not configured in the auto mode, power savings may be achieved by disabling the switchers when not needed, or running them in PFM mode, if loading conditions are light enough. SW1, SW2, SW3, and SW4 can be configured for mode switching with STANDBY or autonomously, based on load current with adaptive mode control (Auto). Additionally, provisions are made for maintaining PFM operation in USEROFF and MEMHOLD modes, to support state retention for faster startup from the low power Off modes, for Warm Start or Warm Boot. POWER GATING SYSTEM The low power Off states are provided to allow faster system booting from two pseudo Off conditions: Memory Hold, which keeps external memory powered for self refresh, and User Off, which keeps the processor powered up for state retention. For reduced current drain in low power Off states, parts of the system can benefit from power gating, to isolate the minimum essentials for such operational modes. It is also necessary to ensure that the power budget on backed up domains is within the capabilities of switchers in PFM mode. An additional benefit of power gating peripheral loads during system startup is to enable the processor core to complete booting and begin running software before additional supplies or peripheral devices are powered. This allows system software to bring up the additional supplies and close power gating switches in the most optimum order 13892 Analog Integrated Circuit Device Data Freescale Semiconductor 67 Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not available from Freescale for import or sale in the United States prior to September 2010: MC13892VK and MC13892VL in 139, 186 MAPBGA packages. FUNCTIONAL DEVICE OPERATION OPERATIONAL MODES to avoid problems with supply sequencing or transient current surges. The power gating switch drivers and integrated control are included for optimizing the system power tree. The power gate drivers could be used for other general power gating as well. The text herein assumes the standard application of PWGT1 for core supply power gating and PWGT2 for Memory Hold power gating. USER OFF POWER GATING User Off configuration maintains PFM mode switchers on both the processor and external memory power domains. PWGTDRV1 is provided for power gating peripheral loads sharing the processor core supply domain(s) SW1, and/or SW2, and/or SW3. In addition, PWGTDRV2 provides support to power gate peripheral loads on the SW4 supply domain. In a typical application, SW1, SW2, and SW3 will be kept active for the processor modules in state retention, and SW4 will be retained for the external memory in self refresh mode. SW1, SW2, and SW3 power gating FETs drive would typically be connected to PWGTDRV1 (for parallel NMOS switches). The SW4 power gating FET drive would typically be connected to PWGTDRV2. When low power Off mode is activated, the power gate drive circuitry will be disabled, turning off the NMOS power gate switches, to isolate the maintained supply domains from any peripheral loading. MEMORY HOLD POWER GATING As with the User Off power gating strategy described previously, Memory Hold power gating is intended to allow isolation of the SW4 power domain to selected circuitry in low power modes, while cutting off the switcher domain from other peripheral loads. The only difference is that processor supplies SW1, and/or SW2, and/or SW3 are shut down in Memory Hold, so just the external memory is maintained in self-refresh mode. An external NMOS is to be placed between the directconnected memory supply and any peripheral loading. The PWGTDRV2 pin controls the gate of the external NMOS, and is normally pulled up to a charge pumped voltage (~5.0 V). During Memory Hold or User Off, PWGTDRV2 will go low to turn off the NMOS switch and isolate memory on the SW4 power domain. POWER DISSIPATION During operation, the temperature of the die should not exceed the maximum junction temperature. Depending on the operating ambient temperature and the total internal dissipation, this limit can be exceeded. To optimize the thermal management scheme and avoid overheating, the 13892 provides a thermal management system. The thermal protection is based on a circuit with a voltage output that is proportional to the absolute temperature. This voltage can be read out via the ADC for precise temperature readouts (See Functional Device Operation). THERMAL PROTECTION Thermal protection is integrated to power off the 13892 and disable the charger circuitry in case of over dissipation. This thermal protection will act above the maximum junction temperature to avoid any unwanted power downs. The protection is debounced by one period of the 32kHz clock in order to suppress any (thermal) noise. This protection should be considered as a fail-safe mechanism and therefore the application design should be dimensioned such that this protection is not tripped under normal conditions. The temperature thresholds are listed in the last section of Table 4. 13892 68 Analog Integrated Circuit Device Data Freescale Semiconductor Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not available from Freescale for import or sale in the United States prior to September 2010: MC13892VK and MC13892VL in 139, 186 MAPBGA packages.
