Functional description 8.1 Serial controller The serial controller includes the following functions: • • • • • • I2C-bus slave interface Interrupt generator Mode Control registers OTG registers Interrupt related registers Device identification registers. The serial controller acts as an I2C-bus slave, and uses the SCL and SDA pins to communicate with the OTG controller. For more details on serial controller, see Section 11. 8.2 VBUS charge pump The charge pump supplies current to the VBUS line. It can operate in any of the following modes: • Output 5 V at current greater than 8 mA • Pull-up VBUS to 3.3 V through a resistor (RVBUS(PU)) for initiating VBUS pulsing SRP • Pull-down VBUS to ground through a resistor (RVBUS(PD)) for discharging VBUS before initiating SRP. 8.3 VBUS comparators VBUS comparators provide indications regarding the voltage level on VBUS. 8.3.1 VBUS valid comparator This comparator is used by an A-device to determine whether or not the voltage on VBUS is at a valid level for operation. The minimum threshold for the VBUS valid comparator is 4.4 V. Any voltage on VBUS below this threshold is considered to be a fault. During power up, it is expected that the comparator output will be ignored. 8.3.2 Session valid comparator The session valid comparator is a TTL-level input that determines when VBUS is high enough for a session to start. Both the A-device and the B-device use this comparator to detect when a session is being started. The A-device also uses this comparator to indicate when a session is completed. The session valid threshold of the ISP1301 is between 0.8 V and 2.0 V. 8.3.3 Session end comparator The session end comparator determines when VBUS is below the B-device session end threshold of 0.2 V to 0.8 V. © Koninklijke Philips Electronics N.V. 2004.

The ID detector also has a switch that can be used to ground pin ID. This switch is controlled by bit ID_PULLDOWN in the serial controller. 8.5 Pull-up and pull-down resistors The pull-up and pull-down resistors include the following switchable resistors: • • • • Pin DP pull-up Pin DP pull-down Pin DM pull-up Pin DM pull-down. The pull-up resistor is a context variable as described in the ECN_27%_Resistor document. The variable pull-up resistor hardware is implemented to meet the USB ECN_27% specification. 8.6 USB transceiver (ATX) The behavior of the USB transceiver depends on the operation mode of the ISP1301: • In the USB mode, the USB transceiver block performs USB full-speed or low-speed transceiver functions. This includes differential driver, differential receiver and single-ended receivers. • In the transparent general purpose buffer mode or the UART mode, the USB transceiver block functions as a level shifter between the pins DAT/VP and SE0/VM and the pins DP and DM. 8.7 3.3 V DC-DC regulator The built-in 3.3 V DC-DC regulator conditions the supply voltage (VBAT) for use in the ISP1301: • VBAT = 3.6 V to 4.5 V: the regulator will output 3.3 V ± 10 % • VBAT < 3.6 V: the regulator will be bypassed. The output of the regulator can be monitored on the VREG(3V3) pin. 8.8 Car kit interrupt detector The car kit interrupt detector is a comparator that detects when the DP line is below the car kit interrupt threshold VPH_CR_INT (0.4 V to 0.6 V). The car kit interrupt detector is enabled in the audio mode only (bit AUDIO_EN = 1). © Koninklijke Philips Electronics N.V. 2004.

On reset (including power-on reset), the level on this pin is latched as ADR_REG, which represents the least significant bit (LSB) of the I2C address of the ISP1301. If bit ADR_REG = 0, the I2C-bus address for the ISP1301 is 0101100 (0x2C); if bit ADR_REG = 1, the I2C-bus address for the ISP1301 is 0101101 (0x2D). After reset, the ADR/PSW pin can be programmed as an output. If in the Mode Control 2 register bit PSW_OE = 1, then the ADR/PSW output will be enabled. The logic level will be determined by bit ADR_REG. If bit ADR_REG = 0, then the ADR/PSW pin will drive HIGH. If bit ADR_REG = 1, then the ADR/PSW pin will drive LOW. The ADR/PSW pin can be used to turn on or off the external charge pump. The ISP1301 built-in charge pump supports VBUS current at 8 mA. If the application needs more current support (for example, 50 mA), an external charge pump may be needed. In this case, the ADR/PSW pin can act as a power switch for the external charge pump. Figure 4 shows an example of using external charge pump. +3.3 V 100 kΩ VBAT ADR/PSW VIN VOUT VBUS 4.7 µF CHARGE PUMP ISP1301 ID DM DP VBUS ON/OFF GND 004aaa437 Fig 4. Using external charge pump. 8.9.2 SCL and SDA The SCL (serial clock) and SDA (serial data) signals implement a two-wire serial I2C-bus. 8.9.3 RESET_N Active LOW asynchronous reset for all digital logic. Either connect this pin to VDD_LGC for power-on reset or apply a minimum of 10 µs LOW pulse for hardware reset. 8.9.4 INT_N The INT_N (interrupt) pin is asserted while an interrupt condition exists. It is deasserted when the Interrupt Latch register is cleared. The INT_N pin is open-drain, and, therefore, can be connected using a wired-AND with other interrupt signals. © Koninklijke Philips Electronics N.V. 2004.

When bit TRANSP_EN = 0 and bit UART_EN = 0, the OE_N/INT_N pin controls the direction of DAT/VP, SE0/VM, DP and DM as indicated in Table 4. When suspended (either pin SUSPEND = HIGH or bit SUSPEND_REG = 1) and bit OE_INT_EN = 1, pin OE_N/INT_N becomes a push-pull output (active LOW) to indicate the interrupt condition. 8.9.6 SE0/VM, DAT/VP, RCV, VM and VP The ISP1301 transmits USB data on the USB line under the following conditions: • Bit TRANSP_EN = 0 • Bit UART_EN = 0 • Pin OE_N/INT_N = LOW. Table 10 shows the operation of the SE0/VM and DAT/VP pins during the transmit operation. The RCV pin is not used during transmit. The ISP1301 receives USB data from the USB line under the following conditions: • Bit TRANSP_EN = 0 • Bit UART_EN = 0 • Pin OE_N/INT_N = HIGH. Table 12 shows the operation of the SE0/VM, DAT/VP and RCV pins during the receive operation. The VP and VM pins are single-ended receiver outputs of the DP and DM pins, respectively. 8.9.7 DP and DM The DP (data plus) and DM (data minus) pins implement the USB data signals. When in the transparent general-purpose buffer mode, the ISP1301 operates as a level shifter between the (DAT/VP, SE0/VM) and (DP, DM) pins. 8.9.8 ID The ID (identification) pin is connected to the ID pin on the USB mini receptacle. An internal pull-up resistor (to VREG(3V3)) is connected to this pin. When bit ID_PULLDOWN is set, the ID pin will be shorted to ground. 8.9.9 VBUS This pin acts as an input to the VBUS comparator or an output from the charge pump. When the VBUS_DRV bit of the OTG Control register is asserted, the ISP1301 tries to drive VBUS to a voltage of 4.4 V to 5.25 V with an output current capability of at least 8 mA. © Koninklijke Philips Electronics N.V. 2004.

The ISP1301 operates when VBAT is between 2.7 V and 4.5 V. 8.9.11 C1 and C2 The C1 and C2 pins are for connecting the flying capacitor of the charge pump. The output current capacity of the charge pump depends on the value of the capacitor. For maximum efficiency, place capacitors as close as possible to the pins.

AGND, CGND and DGND AGND, CGND and DGND are ground pins for analog, charge pump and digital circuits, respectively. These pins can be connected separately or together depending on the system performance requirements. © Koninklijke Philips Electronics N.V. 2004.

Modes of operation There are four types of modes in the ISP1301: • • • • Power modes Direct I2C-bus mode USB modes Transparent modes. 9.1 Power modes The power modes of the ISP1301 are as follows: • Active power mode: power is on. • USB suspend mode: to reduce power consumption, the USB differential receiver is powered down. • Global power-down mode: set bit GLOBAL_PWR_DN = 1 of the Mode Control 2 register; the differential transmitter and receiver, clock generator, charge pump, and all biasing circuits are turned off to reduce power consumption to the minimum possible; for details on waking up the clock, see Section 12. 9.2 Direct I2C-bus mode In the direct I2C-bus mode, an external I2C-bus master (OTG controller) directly communicates with the serial controller through the SCL and SDA lines. The serial controller has a built-in I2C-bus slave function. In this mode, an external I2C-bus master can access the internal registers of the device (Status, Control, Interrupt, and so on) through the I2C-bus interface. The supported I2C-bus bit rate is 100 kbit/s (maximum). The ISP1301 is in the direct I2C-bus mode when either bit TRANSP_EN bit = 0 or pin OE_N/INT_N is deasserted. 9.3 USB modes The four USB modes of the ISP1301 are: • • • • VP_VM unidirectional mode VP_VM bidirectional mode DAT_SE0 unidirectional mode DAT_SE0 bidirectional mode. In the VP_VM USB mode, the DAT/VP pin is used for the VP function, the SE0/VM pin is used for the VM function, and the RCV pin is used for the RCV function. In the DAT_SE0 USB mode, the DAT/VP pin is used for the DAT function, the SE0/VM pin is used for the SE0 function, and the RCV pin is not used. In the unidirectional mode, the DAT/VP and SE0/VM pins are always inputs. In the bidirectional mode, the direction of these signals depends on the OE_N/INT_N input. © Koninklijke Philips Electronics N.V. 2004.

The ISP1301 is in the USB mode when both the TRANSP_EN and UART_EN bits are cleared. 9.4 Transparent modes 9.4.1 Transparent general-purpose buffer mode In the transparent general-purpose buffer mode, the DAT/VP and SE0/VM pins are connected to the DP and DM pins, respectively. Using bits TRANSP_BDIR1 and TRANSP_BDIR0 of the Mode Control 2 register as specified in Table 8, you can control the direction of data transfer. The ISP1301 is in the transparent general-purpose buffer mode if bit TRANSP_EN = 1 and bit DAT_SE0 = 1. 9.4.2 Transparent UART mode When in the transparent UART mode, the ATX behaves as two logic level translator between the following pins: • For TxD signal: from SE0/VM (VDD_LGC level) to DM (+3.3 V level) • For RxD signal: from DP (+3.3 V level) to DAT/VP (VDD_LGC level). In the UART mode, the OTG controller is allowed to connect a UART to the DAT/VP and SE0/VM pins of the ISP1301. The UART mode is entered by setting the UART_EN bit in the Mode Control 1 register. The UART mode is equivalent to one of the transparent general purpose buffer mode (bit TRANSP_BDIR1 = 1, bit TRANSP_BDIR0 = 0). 9.4.3 Table 4: Summary tables Device operating modes Mode USB Bit suspend DAT condition[1] _SE0 Pin OE_N/ INT_N Bit Bit TRANSP UART _EN _ EN Description Direct I2C-bus mode Direct I2C-bus mode X X X 0 X X X HIGH 1 X X 1 X 1 X USB modes USB suspend mode 1 X X 0 0 see Table 5 and Table 7 USB functional mode 0 X X 0 0 ATX is fully functional; see Table 6 Transparent general-purpose buffer mode X 1 X 1 0 ATX is not functional; see Table 8 Transparent UART mode X X X X 1 DAT/VP <= DP (RxD signal of UART) Transparent modes SE0/VM => DM (TxD signal of UART); ATX is not functional [1] Conditions: a) bit SPD_SUSP_CTRL = 0 and pin SUSPEND = HIGH, or b) bit SPD_SUSP_CTRL = 1 and bit SUSPEND_REG = 0. © Koninklijke Philips Electronics N.V. 2004.

Any of the signals given in Table 26 can generate an interrupt when the signal becomes either LOW or HIGH. After an interrupt has been generated, the OTG controller should be able to read the status of each signal and the bit that indicates whether or not that signal generated the interrupt. A bit in the Interrupt Latch register is set when any of these occurs: • Writing logic 1 to its set address causes the corresponding bit to be set • The corresponding bit in the Interrupt Enable High register is set, and the associated signal changes from LOW to HIGH • The corresponding bit in the Interrupt Enable Low register is set, and the associated signal changes from HIGH to LOW. © Koninklijke Philips Electronics N.V. 2004. All rights reserved. 9397 750 11355 Product data Rev. 01 — 14 April 2004 22 of 46 ISP1301 Philips Semiconductors USB OTG transceiver The Interrupt Latch register bit is cleared by writing logic 1 to its clear address. 11.3 Autoconnect The Host Negotiation Protocol (HNP) in the OTG supplement specifies the following sequence of events to transfer the role of the host from the A-device to the B-device: 1. The A-device puts the bus in the suspend state 2. The B-device simulates a disconnect by deasserting its DP pull-up 3. The A-device detects SE0 on the bus, and asserts its DP pull-up 4. The B-device detects that the DP line is HIGH, and takes the role of the host. The OTG supplement specifies that the time between the B-device deasserting its DP pull-up and the A-device asserting its pull-up must be less than 3 ms. For an A-device with a slow interrupt response time, 3 ms may not be enough time to write an I2C-bus command to the ISP1301 to assert the DP pull-up. An alternative method is for the A-device transceiver to automatically assert the DP pull-up after detecting an SE0 from the B-device. The sequence of events is as follows: After finishing data transfers between the A-device and the B-device and before suspending the bus, the A-device sends SOFs. The B-device receives these SOFs, and does not transmit any packet back to the A-device. During this time, the A-device sets the BDIS_ACON_EN bit in the ISP1301. This enables the ISP1301 to look for SE0 whenever the A-device is not transmitting (that is, whenever the OE_N/INT_N pin of the ISP1301 is not asserted). After the BDIS_ACON_EN bit is set, the A-device stops transmitting SOFs and allows the bus to go to the idle state. If the B-device disconnects, the bus goes to SE0, and the ISP1301 logic automatically turns on the A-device pull-up. © Koninklijke Philips Electronics N.V. 2004.

Clock wake up scheme This section explains the ISP1301 clock stop timing, events triggering the clock to wake up, and the timing of the clock wake up. 12.1 Power down event The clock is stopped when the GLOBAL_PWR_DN bit is set. It takes approximately 8 ms for the clock to stop from the time the power down condition is detected. The clock always stops at its falling edge. The waveform is given in Figure 6. SCL GLOBAL_PWR_DN CLOCK 8 ms 004aaa217 Fig 6. Clock stopped using the GLOBAL_PWR_DN bit. 12.2 Clock wake up events The clock wakes up when any of the following events occur on the ISP1301 pins: • SCL goes LOW • VBUS goes above the session valid threshold (0.8 V to 2.0 V), provided the SESS_VLD bit in the Interrupt Enable High register is set. • ID changes when mini-A plug is inserted, provided the ID_FLOAT bit in the Interrupt Enable Low register is set. • ID changes when mini-A plug is removed, provided the ID_FLOAT bit in the Interrupt Enable High register is set. • DP goes HIGH, provided the DP_HI bit in the Interrupt Enable High register is set. • DM goes HIGH, provided the DM_HI bit in the Interrupt Enable High register is set. The event triggers the clock to start and a stable clock is guaranteed after about six clock periods, which is approximately 8 µs. The startup analog clock time is 10 µs. Therefore, the total estimated start time after a triggered event is about 20 µs. The clock will always start at its rising edge. Waveforms of the clock wake up because of different events are given in Figure 7, Figure 8, Figure 9, Figure 10 and Figure 11. SCL CLOCK 20 µs 004aaa218 Fig 7.

Clock wake up by data line SRP. When an event is triggered and the clock is started, it will remain active for 8 ms. If the GLOBAL_PWR_DN bit is not cleared within this 8 ms period, the clock will stop. If the clock wakes up because of any event other than SCL going LOW, an interrupt will be generated once the clock is active. © Koninklijke Philips Electronics N.V. 2004.

Soldering 20.1 Introduction to soldering surface mount packages This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our Data Handbook IC26; Integrated Circuit Packages (document order number 9398 652 90011). There is no soldering method that is ideal for all surface mount IC packages. Wave soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch SMDs. In these situations reflow soldering is recommended. In these situations reflow soldering is recommended. 20.2 Reflow soldering Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Driven by legislation and environmental forces the worldwide use of lead-free solder pastes is increasing. Several methods exist for reflowing; for example, convection or convection/infrared heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. Typical reflow peak temperatures range from 215 to 270 °C depending on solder paste material. The top-surface temperature of the packages should preferably be kept: • below 225 °C (SnPb process) or below 245 °C (Pb-free process) – for all BGA, HTSSON..T and SSOP..T packages – for packages with a thickness ≥ 2.5 mm – for packages with a thickness < 2.5 mm and a volume ≥ 350 mm3 so called thick/large packages. • below 240 °C (SnPb process) or below 260 °C (Pb-free process) for packages with a thickness < 2.5 mm and a volume < 350 mm3 so called small/thin packages. Moisture sensitivity precautions, as indicated on packing, must be respected at all times. 20.3 Wave soldering Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. To overcome these problems the double-wave soldering method was specifically developed. If wave soldering is used the following conditions must be observed for optimal results: • Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. © Koninklijke Philips Electronics N.V. 2004. All rights reserved. 9397 750 11355 Product data Rev. 01 — 14 April 2004 42 of 46 ISP1301 Philips Semiconductors USB OTG transceiver • For packages with leads on two sides and a pitch (e): – larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; – smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves at the downstream end. • For packages with leads on four sides, the footprint must be placed at a 45° angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Typical dwell time of the leads in the wave ranges from 3 to 4 seconds at 250 °C or 265 °C, depending on solder material applied, SnPb or Pb-free respectively. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 20.4 Manual soldering Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 °C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 °C. 20.5 Package related soldering information Table 52: Suitability of surface mount IC packages for wave and reflow soldering methods Package[1] Soldering method BGA, HTSSON..T[3], LBGA, LFBGA, SQFP, SSOP..T[3], TFBGA, USON, VFBGA Reflow[2] not suitable suitable DHVQFN, HBCC, HBGA, HLQFP, HSO, HSOP, not suitable[4] HSQFP, HSSON, HTQFP, HTSSOP, HVQFN, HVSON, SMS suitable PLCC[5], SO, SOJ suitable suitable recommended[5][6] suitable LQFP, QFP, TQFP not SSOP, TSSOP, VSO, VSSOP not recommended[7] suitable CWQCCN..L[8], not suitable not suitable [1] [2] PMFP[9], WQCCN..L[8] For more detailed information on the BGA packages refer to the (LF)BGA Application Note (AN01026); order a copy from your Philips Semiconductors sales office. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods. © Koninklijke Philips Electronics N.V. 2004.

The package body peak temperature must be kept as low as possible. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. Wave soldering is suitable for LQFP, QFP and TQFP packages with a pitch (e) larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. Wave soldering is suitable for SSOP, TSSOP, VSO and VSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. Image sensor packages in principle should not be soldered. They are mounted in sockets or delivered pre-mounted on flex foil. However, the image sensor package can be mounted by the client on a flex foil by using a hot bar soldering process. The appropriate soldering profile can be provided on request. Hot bar soldering or manual soldering is suitable for PMFP packages. 21.
