MC13783 Detailed Block Diagram MC13783 Technical Data, Rev. 3.5 Freescale Semiconductor 3 Introduction Audio The audio section is composed of microphone amplifiers and speaker amplifiers, a voice CODEC, and a stereo DAC. Three microphone amplifiers are available for amplification of two handset microphones and of the headset microphone. The feedback networks are fully integrated for a current input arrangement. A line input buffer amplifier is provided for connecting external sources. All microphones have their own stabilized supply with an integrated microphone sensitivity setting. The microphone supplies can be disabled. The headset microphone supply has a fully integrated microphone detection. Several speaker amplifiers are provided. A bridged earpiece amplifier is available to drive an earpiece. Also, a battery supplied bridged amplifier with thermal protection is included to drive a low ohmic speaker for speakerphone and alert functionality. The performance of this amplifier allows it to be used as well for earpiece drive to support applications with a single transducer combining earpiece, speakerphone and alert functionality, thus avoiding the use of multiple transducers. A left audio out is provided which in combination with a discrete power amplifier and the integrated speaker amplifier allows for a stereo speaker application. Two, single-ended amplifiers are included for the stereo headset drive including headset detection. The stereo headset return path is connected to a phantom ground which avoids the use of large DC decoupling capacitors. The additional stereo receive signal outputs can be used for connection to external accessories like a car kit. Via a stereo line in, external sources such as an FM radio or standalone midi ringer can be applied to the receive path. A voice CODEC with a dual path ADC is implemented following GSM audio requirements. Both narrow band and wide band voice is supported. The dual path ADC allows for conversion of two microphone signal sources at the same time for noise cancellation or stereo applications as well as for stereo recording from sources like FM radio. A 16-bit stereo DAC is available which supports multi-clock modes. An on-board PLL ensures proper clock generation. The voice CODEC and the stereo DAC can be operated at the same time via two interchangeable buses supporting master and slave mode, network mode, as well as the different protocols like I2S. Volume control is included in both transmit and receive paths. The latter also includes a balance control for stereo. The mono adder in the receive path allows for listening to a stereo source on a mono transducer. The receive paths for stereo and mono are separated to allow the two sources to be played back simultaneously on different outputs. The different sources can be analog mixed and two sources on the SSI configured in network mode can be mixed as well. 1.2 Switchers and Regulators The MC13783 provides most of the telephone reference and supply voltages. Four down converters and an up converter are included. The down, or buck, converters provide the supply to the processors and to other low voltage circuits such as IO and memory. The four down converters can be combined into two higher power converters. Dynamic voltage scaling is provided on each of the down converters. This allows under close processor control to adapt the output voltage of the converters to minimize processor current drain. The up, or boost, converter supplies the white backlight LEDs and the MC13783 Technical Data, Rev. 3.5 4 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: MC13783 Product Family 1.1 Introduction The regulators are directly supplied from the battery or from the switchers and include supplies for IO and peripherals, audio, camera, multi media cards, SIM cards, memory and the transceivers. Enables for external discrete regulators are included as well as a vibrator motor regulator. A dedicated preamplifier audio output is available for multifunction vibrating transducers. Drivers for power gating with external NMOS transistors are provided including a fully integrated charge pump. This will allow to power down parts of the processor to reduce leakage current. 1.3 Battery Management The MC13783 supports different charging and supply schemes including single path and serial path charging. In single path charging, the phone is always supplied from the battery and therefore always has to be present and valid. In a serial path charging scheme, the phone can operate directly from the charger while the battery is removed or deeply discharged. The charger interface provides linear operation via an integrated DAC and unregulated operation like used for pulsed charging. It incorporates a standalone trickle charge mode in case of a dead battery with 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 is completed by 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. 1.4 Logic The MC13783 is fully programmable via SPI bus. Additional communication is provided by direct logic interfacing. Default startup of the device is selectable by hard-wiring the power up mode select pins. Both the call processor and the applications processor have full access to the MC13783 resources via two independent SPI busses. The primary SPI bus is able to allow the secondary SPI bus to control all or some of the registers. On top of this an arbitration mechanism is built in for the audio, the power and ADC functions. This together will avoid programming conflicts in case of a dual processor type of application. The power cycling of the phone is driven by the MC13783. It has the interfaces for the power buttons and dedicated signaling interfacing with the processor. It also ensures the supply of the memory and other circuits from the coin cell in case of brief power failures. A charger for the coin cell is included as well. Several pre-selectable power modes are provided such as SDRAM self refresh mode and user off mode. The MC13783 provides the timekeeping based on an integrated low power oscillator running with a standard watch crystal. This oscillator is used for internal clocking, the control logic, and as a reference for the switcher PLL. The timekeeping includes time of day, calendar and alarm. The clock is put out to the processors for reference and deep sleep mode clocking.

The boost converter output has a backlight headroom tracking option to reduce overall power consumption. Signal Descriptions Miscellaneous Functions The drivers and comparators for a USB On-the-Go and a CEA-936-A compatible USB carkit including audio routing, as well as RS232 interfaces are provided. Special precautions are taken to allow for specific booting and accessory detection modes. Current sources are provided to drive tricolored funlights and signaling LEDs. The funlights have preprogrammed lighting patterns. The wide programmability of the tricolored LED drivers allows for applications such as audio modulation. Three backlight drivers with auto dimming are included as well for keypad and dual display backlighting. A dedicated interface in combination with the A to D converter allow for precise resistive touchscreen reading. Pen touch wake up is included. 2 Signal Descriptions The below pinout description gives the pin name per functional block with its row-column coordinates, its maximum voltage rating, and a functional description.

Via these registers the MC13783 resources can be controlled. The registers also provide status information about how the MC13783 IC is operating as well as information on external signals. The SPI interface is comprised of the signals listed below. Table 4.

Therefore, all SPI bus names without prefix PRI or SEC correspond to both the PRISPI and SECSPI interfaces. The control bits are organized into 64 fields. Each of these 64 fields contains 32 bits. A maximum of 24 data bits is used per field. In addition, there is one “dead” bit between the data and address fields. The remaining bits include 6 address bits to address the 64 data fields and one write enable bit to select whether the SPI transaction is a read or a write. For each SPI transfer, first a one is written to the read/write bit if this SPI transfer is to be a write. A zero is written to the read/write bit if this is to be a read command only. If a zero is written, then any data sent after the address bits are ignored and the internal contents of the field addressed do not change when the 32nd CLK is sent. Next the 6-bit address is written, MSB first. Finally, data bits are written, MSB first. Once all the data bits are written then the data is transferred into the actual registers on the falling edge of the 32nd CLK.

The CS line must remain active during the entire SPI transfer. In case the CS line goes inactive during a SPI transfer all data is ignored. To start a new SPI transfer, the CS line must go inactive and then go active again. The MISO line will be tri-stated while CS is low. Note that not all bits are truly writable. Refer to the individual subcircuit descriptions to determine the read/write capability of each bit. All unused SPI bits in each register must be written to a zero. SPI readbacks of the address field and unused bits are returned as zero. To read a field of data, the MISO pin will output the data field pointed to by the 6 address bits loaded at the beginning of the SPI sequence.

MC13783 Technical Data, Rev. 3.5 20 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: MC13783 Product Family Tclkper CS Functional Description 4.1.2.1 Clock Generation and Real Time Clock Clock Generation The MC13783 generates a 32.768 kHz clock as well as several 32.768 kHz derivative clocks that are used internally for control. In addition, a 32.768 kHz square wave is output to external pins. 4.1.2.1.1 Clocking Scheme The MC13783 contains an internal RC oscillator powered from VATLAS that delivers a 32 kHz nominal frequency (±20%) at its output when an external 32.768 kHz crystal is not present. The RC oscillator will then be used to run the debounce logic, the PLL for the switchers, the real time clock (RTC) and internal control logic, and can also be output on the CLK32K pin. 4.1.2.2 Real Time Clock This section provides an overview of the Real Time Clock (RTC). 4.1.2.2.1 Time and Day Counters The real time clock runs from the 32 kHz clock. This clock is divided down to a 1 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 1Hz time tick can be used to generate an 1HZI interrupt. The 1HZI can be masked with corresponding 1HZM mask bit. If the TOD and DAY registers are read at a point in time in which DAY is incremented, then care must be taken that, if DAY is read first, DAY has not changed before reading TOD. In order to guarantee stable TOD and DAY data, all SPI reads and writes to TOD and DAY data should happen immediately after the 1HZI interrupt occurs. Alternatively, TOD or DAY readbacks could be double-read and then compared to verify that they haven't changed. This requirement results from the fact that the 32.768 kHz clock is completely independent of the SPI clock and the two cannot be synchronized. 4.1.2.2.2 Time of Day Alarm A Time Of Day (TOD) alarm function can be used to turn on the phone and alert the processor. If the phone 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. MC13783 makes it convenient to schedule multiple daily events, where a single list could be used, or to skip any number of days.

It also uses on-chip signals and detector outputs. It supports a system with different operating modes as described below. Table 8. MC13783 Operating Modes Mode Description Off Only the MC13783 core circuitry at VATLAS and the RTC module are powered. To exit the Off mode requires a turn on event. Cold Start The switchers and regulators are powered up sequentially to limit the inrush current. At the end of the start-up phase, the RESETB and RESETBMCU will be made high and the circuit transitions to On. On The circuit is fully powered and under SPI control. To stay in this mode, the WDI pin has to be high and remain high. If not, the part will transition to Off mode. Memory Hold All switchers and regulators are powered off except for VBKUP1 and VBKUP2. The RESETB and RESETBMCU are low. The MC13783 enters Cold Start mode when a turn on event occurs. User Off All switchers and regulators are powered off except for VBKUP1 and VBKUP2. RESETB is low and RESETBMCU is kept high. The 32 kHz output signal CLK32KMCU can be maintained in this mode as well. The MC13783 enters Warm Start mode when a turn on event occurs. Warm Start The switchers and regulators are powered up sequentially to limit the inrush current. The reset signals RESETB is kept low and RESETBMCU is kept high and CLK32KMCU can be kept active. At the end of the warm start up phase, the RESETB will be made high and the circuit transitions to On. Power Cuts Defined as a momentary loss of power. This can be caused by battery contact bounce or a user-initiated battery swap. The memory and the processor core are automatically backed up in that case by the coin cell depending on the power cut support mode selected. The maximum duration of a power cut as well as the maximum number of power cuts to be supported are programmable. When exiting the power cut mode due to reapplication of power the system will start up again on the main battery and revert back to the battery supplied modes. Turn On Events If the MC13783 is in Off, User Off or Memory Hold mode, the circuit can be powered on via a turn-on event. The turn-on events are listed below. To indicate to the processor which turn-on event occurred, an interrupt bit is associated with each of the turn-on events. ON1B, ON2B or ON3B pulled low, a power on/off button is connected here. • CHRGRAW pulled high which is equivalent to plugging in a charger. • BP crossing the minimum operating threshold which corresponds to attaching a charged battery to the phone. • VBUS pulled high which is equivalent to plugging in a supplied USB cable. • Time of day alarm which allows powering up a phone at a preset time. The default power up state and sequence of the MC13783 is controlled by the power up mode select pins PUMS1, PUMS2 and PUMS3. In total three different sequences and five different default voltage setting combinations are provided. At power up all regulators and switchers are sequentially enabled at equidistant steps of 2ms to limit the inrush current.

The buck switchers are designed to directly supply the processor cores. To reduce overall power consumption, core voltages of processors may be varied depending on the mode the processor is in. The DVS scheme of the buck switchers allows to transition between the different set points in a controlled and smooth manner. For reduced current drain in low power modes, parts of a processor may be power gated, that is to say, the supply to that part of the processor is disabled. To simplify the supply tree and to reduce the number of external components while maintaining flexibility, power gate switch drivers are included.

Regulator General Characteristics (continued) Functional Description 4.3.1 4.3.1.1 Audio Dual Digital Audio Bus Interface The MC13783 is equipped with two independent digital audio busses. Both busses consist of a bit clock, word clock, receive data and transmit data signal lines. Both busses can be redirected to either the voice CODEC or the stereo DAC and can be operated simultaneously. In addition to the afore mentioned signal lines, two system clock inputs are provided which can be selected to drive the voice CODEC or the stereo DAC. In the latter case, a PLL is used to generate the proper internal frequencies. During simultaneous use of the both busses, two different system clocks can be selected by the voice CODEC and the stereo DAC. 4.3.1.2 Voice CODEC protocol The serial interface protocol for the voice CODEC can be used in master and in slave mode. In both modes, it can operate with a short or a long frame sync and data is transmitted and received in a two's compliment format. CDCFS[1:0]=01 Short Frame Sync Length = Bit CDCFSINV=0 CDCBCLINV=0 CDCFS[1:0]=10 Long Frame Sync Length = 16 Bit FS FSync BCL BitCLK TX TX HIGH Z 15 14 13 12 11 10 9 8 7 6 5 4 3 0 0 0 RX Don't Care 15 14 13 12 11 10 9 8 7 6 5 4 3 0 0 0 HIGH Z Don't Care Figure 6. Voice Codec Timing Diagram Example 1 When the voice CODEC is in slave mode, the FS input must remain synchronous to the CLI frequency. In master mode all clocks are internally generated based on the CLI signal. Additional programmability of the interface for both master and slave mode include bus protocol selection and FS and BCL inversion. There is also the possibility to activate the clocking circuitry independent from the voice CODEC. 4.3.1.3 Stereo DAC protocol The serial interface protocol for the stereo DAC supports the industry standard MSB justified mode and an I2S mode. In industry standard mode, FS will be held high for one 16-bit data word and low for the next 16 bits. I2S mode is similar to industry standard mode except that the serial data is delayed one BCL period. Data is received in a two's compliment format. A network mode is also available where the stereo MC13783 Technical Data, Rev. 3.5 26 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: MC13783 Product Family 4.3 DAC will operate in its assigned time slot. A total of maximum 4 time slot pairs are supported depending on the settings of the clock speed. In this case, the sync signal is no longer a word select but a short frame sync. In all modes, the polarity of both FS and BCL is programmable by SPI. There is also the possibility to activate the clocking circuitry independent from the stereo DAC. 4.3.1.4 Audio Port Mixing In network mode, the receive data from two right channel time slots and of two left channel time slots can be added. One left/right time slot pair is considered to represent the main audio flow whereas the other time slot pair represents the secondary flow. The secondary flow can be attenuated with respect to the main flow by 0 dB, 6 dB and 12 dB which should be sufficient to avoid clipping of the composite signal. In addition, the composite signal can be attenuated with 0 dB or 6 dB. 4.3.2 4.3.2.1 Voice CODEC A/D Converters The A/D portion of the voice CODEC consists of two A/D converters which convert two incoming analog audio signals into 13-bit linear PCM words at a rate of 8 kHz or 16 kHz. Following the A/D conversion, the audio signal is digitally band pass filtered. The converted voice is available on the audio bus. If both A/D channels are active, the audio bus is operated in a network mode. Table 12.

Telephone CODEC D/A Performance Specifications Functional Description Clock Modes The stereo DAC incorporates a PLL to generate the proper clocks in master and in slave modes. The PLL requires an external C//RC loop filter. In Master Mode, the PLL of the Stereo DAC generates FS and BCL signal based on the reference frequency applied through one of the CLI inputs. The CLI frequencies supported are 3.6864 MHz, 12 MHz, 13 MHz, 15.36 MHz, 16.8 MHz, 26 MHz and 33.6 MHz. The PLL will also generate its own master clock MCL used by the stereo DAC itself. In Slave Mode, FS and BCL are applied to the MC13783 and the MCL is internally generated by the PLL based on either FS or BCL. A special mode is foreseen where the PLL is bypassed and CLI can be used as the MCL signal. In this mode, MCLK must be provided with the exact ratio to FS, depending on the sample rate selected. In the network mode, it’s possible to select up to 8 time slots (4 time slot pairs).

One circuit supplies up to two handset microphones via the two outputs MC1RB and MC1LB. The second circuit supplies the headset microphone via MC2B. The microphone bias resistors of 2.2 kOhm are included. The bias circuits can be enabled and disabled. The bias MC2B includes a microphone detect circuit which monitors the current flow through the output both when the bias is disabled or enabled. This will generate an interrupt to the processor. In this way the attach and removal of a headset microphone is detected. Also it allows to include a send/end series switch with the microphone for signaling purposes. When the output of the MC2B gets out of regulation, an interrupt is generated. This allows for connecting a switch in parallel to the microphone. Table 16.

The selected channel can be fed into the receive channel for test purposes. In addition a second amplified input channel can be selected for the second handset microphone connected to MC1LIN. The gain towards to voice CODEC can be programmed in 1 dB steps from –8 dB to +23 dB. In addition to the microphone amplifier paths, there is also the possibility to route the stereo line in signal from RXINR and RXINL to the voice CODEC dual ADC section. This allows for 13-bit, 16 kHz sampled stereo recording of an analog source such as FM radio.

Audio Output Section Diagram Four signal sources can be used in the receive path. The voice CODEC receive signal, the voice CODEC transmit signal (for test purposes), the stereo DAC and an external stereo source like an FM radio. The latter can also be routed to the voice CODEC ADC section for recording purposes. Each of the input source signals is amplified via an independently programmable gain amplifier. The amplified signals are fed into a mixer where the different signals can be mixed. The mixed signal goes through a mono adder and balance circuit which can create a mono signal out of the stereo input signals, and allows for balance control. Via the selector, the composite signal is then directed to one or more of the outputs. These are the regular phone earpiece (Asp), the loudspeaker for hands free or ringing (Alsp), the stereo headset (Ahsr, Ahsl) and the stereo line out. The voice CODEC output signal can also follow an independent route to all of the amplifiers via the additional selector inputs. In addition to the amplifiers, low power outputs are available at LSPL and CDCOUT.

The input level from the external stereo source can be pre-amplified by Arxin of 18 dB and the programmable gain amplifier PGArxin to get it at the same level as the other sources before going into the audio input mixer block. The amplifiers are programmable in 3 dB steps from –33 dB to +6 dB. 4.3.5.3 Balance, Mixer, Mono Adder and Selector Block The mixer is a summing amplifier where the different input signals can be summed. The relative level between the input signals is to be controlled via the PGArx, PGAst, and PGArxin amplifiers respectively. The mono adder in the stereo channel can be used in four different modes: stereo (right and left channel independent), stereo opposite (left channel in opposite phase), mono (right and left channel added), mono opposite (as mono but with outputs in opposite phase). The balance control allows for attenuating either the right or the left channel with respect to the other channel. The balance control setting is applied independent of which input channel is selected. The selector opens the audio path to the audio amplifiers and can be seen as an analog switch. 4.3.5.4 Earpiece Speaker Amplifier Asp The Asp amplifier drives the earpiece of the phone in a bridge tied load configuration.

It adopts a fully differential topology in order to be able to reach high PSRR performance while Alsp is powered directly by the telephone battery. The feedback network of the Alsp amplifier is fully integrated. Under worst case conditions the dissipation of Alsp is considerable. To protect the amplifier against overheating, a thermal protection is included which shuts down the amplifier when the maximum allowable junction temperature within Alsp is reached. Table 19.

The feedback networks are fully integrated. The return path of the headset is provided by the phantom ground which is at the same DC voltage as the bias of the headset amplifiers. This avoids the use of large sized capacitors in series with the headset speakers. All outputs withstand shorting to ground or to phantom ground. Table 20.

Amplifiers Ahsr and Ahsl Performance Specifications (continued) Functional Description 4.3.6.1 Audio Control Supply The audio section is supplied from a dedicated regulator VAUDIO, except for the loudspeaker amplifier Alsp which is directly supplied from the battery. A low power standby mode controlled by the standby pins is provided for VAUDIO in which the bias current is reduced. The output drive capability and performance are limited in this mode. The nominal output voltage for VAUDIO is 2.775 V. A 1uF (± 35%) bypass capacitor is needed at the output of the VAUDIO regulator. 4.3.6.2 Bias and Anti-Pop The audio blocks have a bias which can be enabled separately from the rest of the MC13783. When enabled, the audio bias voltages can be ramped fast or slow to make any pop sub audio and therefore not audible. 4.3.6.3 Arbitration Logic The audio functions can be operated by both the primary and secondary SPI. 4.4 4.4.1 Battery Management Battery Interface and Control The battery interface is optimized for single charger input coming from a standard wall charger or from a USB bus. The charger has been designed to support three different configurations where the charger and USB bus share the same input pin (CHRGRAW): these are dual path charging, serial path charging, and single path charging. In addition, provisions have been taken for a separate input configuration where the charger and USB supply are on separate inputs. In all cases except for single path charging, the battery interface allows for so called dead battery operation. An example of serial path charging is shown in Section 4.4.1.1, “Serial Path Configuration Example,” on page 37. This section includes the following subsections: • Section 4.4.1.1, “Serial Path Configuration Example,” on page 37 • Section 4.4.1.2, “Charger Operation,” on page 38 • Section 4.4.1.3, “Coin Cell,” on page 38 The mode of operation for the charger interface is selected via the CHRGMOD1 and CHRGMOD0 pins as given in Table 22.

Transistors M1 and M2 control the charge current and provide a voltage clamping function in case of no battery or in case of a dead battery to allow the application to operate. In both cases transistor M3 is non-conducting and the battery is charged with a trickle charge current internal to the MC13783. The transistor M3 is conducting in case the battery has to be connected to the application like for normal operation or for standalone trickle charging. Transistor M2 is non-conducting in case the charger voltage is too high. A current can be supplied from the battery to an accessory by having all transistors M1, M2 and M3 conducting.

Internal trickle charge current Programmable current from 0 to 84mA in steps of 12mA. 4.4.1.2 4.4.1.2.1 Charger Operation CEA-936-A The CEA-936-A carkit specification allows a USB connection to be used not only as an USB interface but also as a generic supply plus analog audio interface. The purpose is to standardize the carkit interface over a USB connection. The USB VBUS line in this case is used to provide a supply within the USB voltage limits and with at least 500 mA of current drive capability. However, this also opens the possibility to create a range of USB compatible wall chargers, referred to as CEA-936-A charger in the remainder of this chapter. The CEA-936-A standard also allows providing a supply from the phone to the accessory over the VBUS line, just like in the USB on the go case. 4.4.1.2.2 Standalone Trickle Charging The MC13783 has a standalone trickle charge mode of operation in order to ensure that a completely discharged battery can be charged without the Microprocessor's control. Upon plugging a valid charger to the phone, the trickle cycle is started. For battery voltages below 2.7 V, the trickle charge current level is set at 70 mA. When the battery voltage increases above the threshold, the trickle charge level is increased to 266 mA. When the battery voltage rises above the threshold sufficient for phone operation, a power up sequence is automatically initiated. Even after the phone has powered up, the Standalone trickle charge will remain on until software enables charging. If the battery voltage was already greater than the voltage needed for phone operation when a charger is attached, the phone will power up immediately without starting a trickle charge cycle. The trickle charge is terminated upon charge completion, time out, or by software control. For the single path charging configuration, standalone trickle charging is only available for the SE1 = LOW condition. The charge level remains constant at the lower 70 mA threshold through all battery voltage ranges—that is, there is no increased charge current at the 2.7 V threshold. Standalone Trickle charging is not available for the SE1 = HIGH / Single Path charging case. 4.4.1.3 Coin Cell The coin cell charger circuit will function as a current-limited voltage source, resulting in the CC/CV taper characteristic typically used for rechargeable Lithium-Ion batteries. The output voltage is selectable. The coin cell charger voltage is programmable in the ON state. In the User Off modes, or in the Off state, the coincell charger will continue to charge to the predefined voltage setting but at a lower maximum current. In practice, this means that if in Off state the coin cell is fully charged, the coin cell charger will only MC13783 Technical Data, Rev. 3.5 38 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: MC13783 Product Family Table 23. Voltage and Current Settings Functional Description 4.4.2 ADC Subsystem 4.4.2.1 Converter Core The ADC core is a 10 bit successive approximation converter. 4.4.2.2 Input Selector The ADC has two groups of 8 input channels. ADSEL selects between two groups of input signals. If set to zero then group 0 is read and stored, if set to 1 then group 1 is read and stored. This is done to shorten the total read time and to reduce the required storage of converted values. The table below gives an overview of the attribution of the A to D channels. Table 24.

The RTC will run from VATLAS in this case. A capacitor should be placed from LICELL to ground if no coin cell is used. Functional Description Control The ADC parameters are programmed by the processors via SPI. Locally on MC13783, the different ADC requests are arbitrated and executed. When a conversion is finished, an interrupt is generated to the processor which started the conversion. 4.4.2.3.1 Starting Conversions The ADC will have the ability to start a series of conversions based on a rising edge of the ADTRIG signal or directly initiated by SPI. Once conversion is initiated all 8 channels will be sequentially converted and stored in registers or eight conversions on one channel will be performed and stored. The conversion result can digitally be compared with respect to a preset value for threshold detection. The conversion will begin after a delay set between 0 and 8 ms. The delay between conversions can be made equal to this delay. To avoid that the ADTRIG input involuntarily triggers a conversion, a bit can be set which will make the ADC ignores any transition on the ADTRIG pin. 4.4.2.3.2 Reading Conversions Once a series of eight A/D conversions is complete, they are stored in one set of eight internal registers and the values can be read out by software. 4.4.2.4 Pulse Generator A SPI controllable pulse generator is available at ADOUT synchronized with the ADC conversion. This pulse can be used to enable or drive external circuits only during the period of 4 or 8 ADC conversions. 4.4.2.5 4.4.2.5.1 Dedicated Channels Reading Battery Current Traditional battery capacity estimation is based on battery terminal voltage reading combined with estimated phone current drain based on emitted PA power. For improved battery capacity estimation, especially in non transmit mode like gaming, this method is too approximate. To improve the estimation, the current out of the battery must be quantified more accurately. For this, on the MC13783, 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. 4.4.2.5.2 Charge Current The charge current is read by monitoring the voltage drop over the charge current sense resistor. 4.4.2.5.3 Battery Thermistor If a battery is equipped with a battery thermistor, its value can be read out via the ADC input ADIN5. The biasing and sensing circuit is entirely integrated and is only powered during the A to D conversions.

Alternatively, the UID voltage can be read out on the ADIN7 channel. 4.4.2.6 Touch Screen Interface The touchscreen interface provides all circuitry required for the readout of a 4-wire resistive touchscreen. The touchscreen X plate is connected to TSX1 and TSX2 while the Y plate is connected to TSY1 and TSY2. A local supply ADREF will serve as a reference. Several readout possibilities are offered. In interrupt mode, a voltage is applied via a high impedance source to only one of the plates, the other is connected to ground. When the two plates make contact both will be at a low potential. This will generate a pen interrupt to the processor. This detection does not make use of the ADC core. A finger will connect both plates over a wider area then a stylus. To distinguish both sources, in the contact resistance mode the resistance between the plates is measured by applying a voltage difference between the X and the Y plate. The current through the plates is measured. Since the plate resistance varies from screen to screen, measuring its value will improve the pressure measurement. Also, it can help in determining if more than 1 spot is touched on the screen. In the plate measurement mode, a potential is applied across one of the plates while the other plate is left floating. The current through the plate is measured. The contact resistance mode and plate measurement mode are together referred to as resistive mode. To determine the XY coordinate pair, in position mode a voltage difference over the X plate is read out via the Y plate for the X-coordinate and vice versa for the Y- coordinate readout. In the MC13783, during the position mode the contact resistance is read as well in addition to the XY coordinate pair. To perform touchscreen readings, the processor will have to set one of the touchscreen interface readout modes, program the delay between the conversions, 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 touchscreen readings are repeated in the readout sequence. In this way, in total eight results are available per readout. Table 25.

Since the data path is 24 bits wide, results for 2 conversion results (10 bits each) can be read back in each SPI read sequence. For support of queued conversion requests, the SPI has the ability to write to the two sets of ADC control, namely “its own” ADC and “the other” ADC or ADC BIS. The write access to the control of ADC BIS is handled via the ADCBISn bits located at bit position 23 of the ADC control registers. By setting this bit to a 1, the control bits which follow are directed to the ADC BIS. ADCBISn will always read back 0 and there is no read access to the ADCBIS control bits. The read results from the ADC conversions are available in two separate registers ADC result registers ADC0 and ADC1. 4.5 Miscellaneous Functions Miscellaneous functions are described in the following sections: • Section 4.5.1, “Connectivity on page 42 • Section 4.5.2, “Lighting System on page 45 4.5.1 Connectivity This section summarizes the following interface information: • Section 4.5.1.1, “USB Interface on page 42 • Section 4.5.1.2, “RS-232 Interface on page 45 • Section 4.5.1.3, “CEA-936-A Accessory Support on page 45 • Section 4.5.1.4, “Booting Support on page 45 4.5.1.1 4.5.1.1.1 USB Interface Supplies The USB interface is supplied by the VUSB (3.3 V) and the VBUS (5.0 V) regulators. The VBUS regulator takes the boost supply and regulates it down to the required USBOTG level which is provided to VBUS in the case of a USBOTG connection. The transceiver itself is supplied from VUSB. The VUSB regulator by default is supplied by BP and by SPI programming can be boost or VBUS supplied as well. 4.5.1.1.2 Detect Comparators are used to detect a valid VBUS, and to support the USB OTG session request protocol. 4.5.1.1.3 Transceiver The USB transceiver data flow is depicted in below diagram. The processor interface IO level is set to USBVCC.

USB/RS232 Transceiver Data Flow Upon a USB legacy host detection, an interrupt is generated but neither the transceiver nor the VUSB regulator are automatically enabled. This must be done by software before data transmission. The transceiver can also be enabled during boot mode. Via SPI bits DATSE0 and BIDIR, one of the four USB operating modes can be selected. However, when starting up in a boot mode, there is no up front SPI programming possible. The default operating mode is then determined by the setting of the UMOD pin as indicated in Table 26.

To indicate the speed to the host an internal 1.5 kOhm pull up to VUSB is used. Via SPI this resistor can be connected to UDP to indicate full speed, or to UDM to indicate low speed. 4.5.1.1.5 USB Suspend USB suspend mode is enabled through SPI. When set, the USB transceiver enters a low power mode which reduces the transceiver current drain to below 500 µA. In USB suspend mode, the VUSB regulator remains enabled and the VBUS detect comparators remain enabled, while the single ended receivers are switched from a comparator to a Schmitt-trigger buffer. 4.5.1.1.6 USB On-The-Go USBOTG support circuitry is added in order to allow a phone to act as a dual-role USBOTG device. In accordance with USBOTG requirements, the pull down resistors on UDP and UDM can be switched in or out individually via SPI. Furthermore, the pulls down resistors are integrated on-chip. The USBOTG specification requires that during the session request protocol, the D+ (full speed) line is pulled up for a duration of 5 to 10 msec. In order to reduce the SPI traffic, the MC13783 has an integrated timer used for this task. To support VBUS pulsing, there is a programmable current limit and timer on the VBUS regulator. During VBUS pulsing, the lower current limit allows for easier detection of a legacy host device on the far end of the USB cable. It is possible to have the transceiver automatically connect the data pull-up to VUSB any time a SE0 is detected. This enables the phone to meet the USBOTG timing requirements without unduly taxing the software.

MC13783 Lighting System 4.5.2.1 Backlight Drivers The backlight drivers are generally intended for White LED (WLED) backlighting of color LCD displays or white/blue LED backlighting for key pads. The drivers consists of independently programmable current sinking channels. SPI registers control programmable features such as DC current level, auto ramping / dimming and PWM settings. Three zones are provided for typical applications which may include backlighting a main display, auxiliary display, and key pad. However, the drivers can be utilized for other lighting schemes such as an integrated WLED flashlight or even non-LED system applications requiring programmable current sinks. The integrated boost switcher provided on the MC13783 is used to supply the backlights. It automatically adapts its output voltage to allow for power optimized biasing of white and/or blue LEDs. Alternatively, any other available source with sufficient current drive and output voltage for necessary diode headroom may be used (5.5 V should not be exceeded). 4.5.2.2 Tri-Color LED Drivers The tri-color circuitry provides expanded capability for independent lighting control and distribution that supplements the backlight drivers circuitry. The tri-color drivers have the same basic programmability as the backlight drivers, with similar bit control for current level, duty cycle control, and ramping.
