ST-NXP Wireless 34.807IRELESS www.stnwireless.com ISP1583 Hi-Speed USB peripheral controller Rev. 07 — 22 September 2008 Product data sheet 1. General description The ISP1583 is a cost-optimized and feature-optimized Hi-Speed Universal Serial Bus (USB) peripheral controller. It fully complies with Ref. 1 “Universal Serial Bus Specification Rev. 2.0”, supporting data transfer at high-speed (480 Mbit/s) and full-speed (12 Mbit/s). The ISP1583 provides high-speed USB communication capacity to systems based on microcontrollers or microprocessors. It communicates with a microcontroller or microprocessor of a system through a high-speed general-purpose parallel interface. The ISP1583 supports automatic detection of Hi-Speed USB system operation. Original USB fall-back mode allows the device to remain operational under full-speed conditions. It is designed as a generic USB peripheral controller so that it can fit into all existing device classes, such as imaging class, mass storage devices, communication devices, printing devices and human interface devices. The ISP1583 is a low-voltage device, which supports I/O pad voltages from 1.65 V to 3.6 V. The internal generic Direct Memory Access (DMA) block allows easy integration into data streaming applications. In addition, the various configurations of the DMA block are tailored for mass storage applications. The modular approach to implementing a USB peripheral controller allows the designer to select the optimum system microcontroller from the wide variety available. The ability to reuse existing architecture and firmware shortens the development time, eliminates risk and reduces cost. The result is fast and efficient development of the most cost-effective USB peripheral solution. The ISP1583 also incorporates features such as SoftConnect, a reduced frequency crystal oscillator and integrated termination resistors. These features allow significant cost savings in system design and easy implementation of advanced USB functionality into PC peripherals. 2.

All rights reserved. Rev. 07 — 22 September 2008 11 of 99 ISP1583 NXP Semiconductors Hi-Speed USB peripheral controller 8. Functional description The ISP1583 is a high-speed USB peripheral controller. It implements the Hi-Speed USB or the Original USB physical layer, and the packet protocol layer. It concurrently maintains up to 16 USB endpoints (control IN, control OUT, and seven IN and seven OUT configurable) along with endpoint EP0 set up, which accesses the set-up buffer. The Ref. 1 “Universal Serial Bus Specification Rev. 2.0”, Chapter 9 protocol handling is executed using the external firmware. The ISP1583 has a fast general-purpose interface to communicate with most types of microcontrollers and microprocessors. This microcontroller interface is configured using pins BUS_CONF/DA0, MODE1 and MODE0/DA1 to accommodate most interface types. Two bus configurations are available, selected using input BUS_CONF/DA0 during power-up: • Generic processor mode (pin BUS_CONF/DA0 = HIGH): – AD[7:0]: 8-bit address bus (selects target register) – DATA[15:0]: 16-bit data bus (shared by processor and DMA) – Control signals: RW_N and DS_N or RD_N and WR_N (selected using pin MODE0/DA1), CS_N – DMA interface (generic slave mode only): Uses lines DATA[15:0] as data bus, DIOR and DIOW as dedicated read and write strobes • Split bus mode (pin BUS_CONF/DA0 = LOW): – AD[7:0]: 8-bit local microprocessor bus (multiplexed address and data) – DATA[15:0]: 16-bit DMA data bus – Control signals: CS_N, ALE or A0 (selected using pin MODE1), RW_N and DS_N or RD_N and WR_N (selected using pin MODE0/DA1) – DMA interface (master or slave mode): Uses DIOR and DIOW as dedicated read and write strobes For high-bandwidth data transfer, the integrated DMA handler can be invoked to transfer data to or from external memory or devices. The DMA interface can be configured by writing to proper DMA registers (see Section 9.4). The ISP1583 supports Hi-Speed USB and Original USB signaling. The USB signaling speed is automatically detected. The ISP1583 has 8 kB of internal FIFO memory, which is shared among enabled USB endpoints, including control IN and control OUT endpoints, and set-up token buffer. There are seven IN and seven OUT configurable endpoints, and two fixed control endpoints that are 64 bytes long. Any of the seven IN and seven OUT endpoints can be separately enabled or disabled. The endpoint type (interrupt, isochronous or bulk) and packet size of these endpoints can be individually configured, depending on the requirements of the application. Optional double buffering increases the data throughput of these data endpoints. The ISP1583 requires 3.3 V power supply. It has 5 V tolerant I/O pads and an internal 1.8 V regulator to power the digital logic. The I/O voltage can range from 1.65 V to 3.6 V. ISP1583_7 Product data sheet © NXP B.V. 2008.

An integrated 40 × PLL clock multiplier generates the internal sampling clock of 480 MHz. 8.1 DMA interface, DMA handler and DMA registers The DMA block can be subdivided into two blocks: DMA handler and DMA interface. The firmware writes to the DMA Command register to start a DMA transfer (see Table 51). The command opcode determines whether a generic DMA, Parallel I/O (PIO) or Multi-word DMA (MDMA) transfer will start. The handler interfaces to the same FIFO (internal RAM) as used by the USB core. On receiving the DMA command, the DMA handler directs the data from the endpoint FIFO to the external DMA device or from the external DMA device to the endpoint FIFO. The DMA interface configures the timing and the DMA handshake. Data can be transferred using either the DIOR and DIOW strobes or the DACK and DREQ handshakes. DMA configurations are set up by writing to the DMA Configuration register (see Table 56 and Table 57). For an IDE-based storage interface, applicable DMA modes are PIO and MDMA (Multi-word DMA; ATA). For a generic DMA interface, DMA modes that can be used are Generic DMA (GDMA) slave. Remark: The DMA endpoint buffer length must be a multiple of 4 bytes. For details on DMA registers, see Section 9.4. ISP1583_7 Product data sheet © NXP B.V. 2008. All rights reserved. Rev. 07 — 22 September 2008 13 of 99 ISP1583 NXP Semiconductors Hi-Speed USB peripheral controller 8.2 Hi-Speed USB transceiver The analog transceiver directly interfaces to the USB cable through integrated termination resistors. The high-speed transceiver requires an external resistor (12.0 kΩ ± 1 %) between pin RREF and ground to ensure an accurate current mirror that generates the Hi-Speed USB current drive. A full-speed transceiver is integrated as well. This makes the ISP1583 compliant to Hi-Speed USB and Original USB, supporting both the high-speed and full-speed physical layers. After automatic speed detection, the NXP Serial Interface Engine (SIE) sets the transceiver to use either high-speed or full-speed signaling. 8.3 MMU and integrated RAM The Memory Management Unit (MMU) manages the access to the integrated RAM that is shared by the USB, microcontroller handler and DMA handler. Data from the USB bus is stored in the integrated RAM, which is cleared only when the microcontroller has read the corresponding endpoint, or the DMA controller has written all data from the RAM of the corresponding endpoint to the DMA bus. The OUT endpoint buffer can also be forcibly cleared by setting bit CLBUF in the Control Function register. A total of 8 kB RAM is available for buffering. 8.4 Microcontroller interface and microcontroller handler The microcontroller interface allows direct interfacing to most microcontrollers and microprocessors. The interface is configured at power-up through pins BUS_CONF/DA0, MODE1 and MODE0/DA1. When pin BUS_CONF/DA0 = HIGH, the microcontroller interface switches to generic processor mode in which AD[7:0] is the 8-bit address bus and DATA[15:0] is the separate 16-bit data bus. If pin BUS_CONF/DA0 = LOW, the interface is in split bus mode, where AD[7:0] is the local microprocessor bus (multiplexed address and data) and DATA[15:0] is solely used as the DMA bus. When pin MODE0/DA1 = HIGH, pins RW_N/RD_N and DS_N/WR_N are the read and write strobes (8051 mode). If pin MODE0/DA1 = LOW, pins RW_N/RD_N and DS_N/WR_N represent the direction and data strobes (Freescale mode). When pin MODE1 = LOW, pin ALE/A0 is used to latch the multiplexed address on pins AD[7:0]. When pin MODE1 = HIGH, pin ALE/A0 is used to indicate address or data. Pin MODE1 is only used in split bus mode; in generic processor mode, it must be tied to VCC(I/O). The microcontroller handler allows the external microcontroller to access the register set in the NXP SIE, as well as the DMA handler. The initialization of the DMA configuration is done through the microcontroller handler. 8.5 OTG SRP module The OTG supplement defines a Session Request Protocol (SRP), which allows a B-device to request the A-device to turn on VBUS and start a session. This protocol allows the A-device, which may be battery-powered, to conserve power by turning off VBUS when there is no bus activity while still providing a means for the B-device to initiate bus activity. Any A-device, including a PC or laptop, can respond to SRP. Any B-device, including a standard USB peripheral, can initiate SRP. ISP1583_7 Product data sheet © NXP B.V. 2008. All rights reserved. Rev. 07 — 22 September 2008 14 of 99 ISP1583 NXP Semiconductors Hi-Speed USB peripheral controller The ISP1583 is a device that can initiate SRP. 8.6 NXP high-speed transceiver 8.6.1 NXP Parallel Interface Engine (PIE) In the High-Speed (HS) transceiver, the NXP PIE interface uses a 16-bit parallel bidirectional data interface. The functions of the HS module also include bit-stuffing or de-stuffing and Non-Return-to-Zero Inverted (NRZI) encoding or decoding logic. 8.6.2 Peripheral circuit To maintain a constant current driver for HS transmit circuits and to bias other analog circuits, an internal band gap reference circuit and an RREF resistor form the reference current. This circuit requires an external precision resistor (12.0 kΩ ± 1 %) connected to the analog ground. 8.6.3 HS detection The ISP1583 handles more than one electrical state, Full-Speed (FS) or High-Speed (HS), under the USB specification. When the USB cable is connected from the peripheral to the host controller, the ISP1583 defaults to the FS state, until it sees a bus reset from the host controller. During the bus reset, the peripheral initiates an HS chirp to detect whether the host controller supports Hi-Speed USB or Original USB. If the HS handshake shows that there is an HS host connected, then the ISP1583 switches to the HS state. In the HS state, the ISP1583 must observe the bus for periodic activity. If the bus remains inactive for 3 ms, the peripheral switches to the FS state to check for a Single-Ended Zero (SE0) condition on the USB bus. If an SE0 condition is detected for the designated time (100 µs to 875 µs; refer to Ref. 1 “Universal Serial Bus Specification Rev. 2.0”, Section 7.1.7.6), the ISP1583 switches to the HS chirp state to perform an HS detection handshake. Otherwise, the ISP1583 remains in the FS state, adhering to the bus-suspend specification. 8.6.4 Isolation Ensure that the DP and DM lines are maintained in a clean state, without any residual voltage or glitches. Once the ISP1583 is reset and the clock is available, ensure that there are no erroneous pulses or glitches even of very small amplitude on the DP and DM lines. Remark: If there are any erroneous unwanted pulses or glitches detected by the ISP1583 DP and DM lines, there is a possibility of the ISP1583 clocking this state into the internal core, causing unknown behaviors. 8.7 NXP Serial Interface Engine (SIE) The NXP SIE implements the full USB protocol layer. It is completely hardwired for speed and needs no firmware intervention. The functions of this block include: synchronization pattern recognition, parallel or serial conversion, bit-stuffing or de-stuffing, CRC checking or generation, Packet IDentifier (PID) verification or generation, address recognition, handshake evaluation or generation.

Rev. 07 — 22 September 2008 15 of 99 ISP1583 NXP Semiconductors Hi-Speed USB peripheral controller 8.8 SoftConnect The USB connection is established by pulling pin DP (for full-speed devices) to HIGH through a 1.5 kΩ pull-up resistor. In the ISP1583, an external 1.5 kΩ pull-up resistor must be connected between pin RPU and 3.3 V. The RPU pin connects the pull-up resistor to pin DP, when bit SOFTCT in the Mode register is set (see Table 24 and Table 25). After a hardware reset, the pull-up resistor is disconnected by default (bit SOFTCT = 0). The USB bus reset does not change the value of bit SOFTCT. When VBUS is not present, the SOFTCT bit must be set to logic 0 to comply with the back-drive voltage. 8.9 Reconfiguring endpoints The ISP1583 endpoints have a limitation when implementing a composite device with at least two functionalities that require the support of alternate settings, for example, the video class and audio class devices. The ISP1583 endpoints cannot be reconfigured on the fly because it is implemented as a FIFO base. The internal RAM partition will be corrupted if there is a need to reconfigure endpoints on the fly because of alternate settings request, causing data corruption. For details and work-around, refer to Ref. 3 “Using ISP1582/3 in a composite device application with alternate settings (AN10071)”. 8.10 System controller The system controller implements the USB power-down capabilities of the ISP1583. Registers are protected against data corruption during wake-up following a resume (from the suspend state) by locking the write access, until an unlock code is written to the Unlock Device register (see Table 90 and Table 91). 8.11 Modes of operation The ISP1583 has two bus configuration modes, selected using pin BUS_CONF/DA0 at power-up: • Split bus mode (BUS_CONF/DA0 = LOW): 8-bit multiplexed address and data bus, and separate 8-bit or 16-bit DMA bus • Generic processor mode (BUS_CONF/DA0 = HIGH): separate 8-bit address and 16-bit data bus Details of bus configurations for each mode are given in Table 5. Typical interface circuits for each mode are given in Section 14. ISP1583_7 Product data sheet © NXP B.V. 2008. All rights reserved.

All rights reserved. Rev. 07 — 22 September 2008 17 of 99 ISP1583 NXP Semiconductors Hi-Speed USB peripheral controller 8.13 Interrupt 8.13.1 Interrupt output pin The Interrupt Configuration register of the ISP1583 controls the behavior of the INT output pin. The polarity and signaling mode of the INT pin can be programmed by setting bits INTPOL and INTLVL of the Interrupt Configuration register (R/W: 10h); see Table 28. Bit GLINTENA of the Mode register (R/W: 0Ch) is used to enable pin INT; see Table 25. Default settings after reset are active LOW and level mode. When pulse mode is selected, a pulse of 60 ns is generated when the OR-ed combination of all interrupt bits changes from logic 0 to logic 1. Figure 5 shows the relationship between interrupt events and pin INT. Each of the indicated USB and DMA events is logged in a status bit of the Interrupt register and the DMA Interrupt Reason register, respectively. Corresponding bits in the Interrupt Enable register and the DMA Interrupt Enable register determine whether an event will generate an interrupt. Interrupts can be masked globally by means of bit GLINTENA of the Mode register. Field CDBGMOD[1:0] of the Interrupt Configuration register controls the generation of INT signals for the control pipe. Field DDBGMODIN[1:0] of the Interrupt Configuration register controls the generation of INT signals for the IN pipe. Field DDBGMODOUT[1:0] of the Interrupt Configuration register controls the generation of INT signals for the OUT pipe; see Table 29. ISP1583_7 Product data sheet © NXP B.V. 2008. All rights reserved.

The behavior of this bit is given in Figure 6. The following illustrations are only applicable for level trigger. Event A: When an interrupt event occurs (for example, SOF interrupt) with bit GLINTENA set to logic 0, an interrupt will not be generated at pin INT. It will, however, be registered in the corresponding Interrupt register bit. Event B: When bit GLINTENA is set to logic 1, pin INT is asserted because bit SOF in the Interrupt register is already set. Event C: If the firmware sets bit GLINTENA to logic 0, pin INT will still be asserted. The bold line shows the desired behavior of pin INT. Deassertion of pin INT can be achieved either by clearing all the bits in the Interrupt register or the DMA Interrupt Reason register, depending on the event. Remark: When clearing an interrupt event, perform write to all the bytes of the register. For more information on interrupt control, see Section 9.2.2, Section 9.2.5 and Section 9.5.1. A B C INT pin GLINTENA = 0 (during this time, an interrupt event occurs, for example, SOF asserted) GLINTENA = 1 SOF asserted GLINTENA = 0 SOF asserted 004aaa394 Pin INT: HIGH = deassert; LOW = assert (individual interrupts are enabled). Fig 6. Behavior of bit GLINTENA 8.14 VBUS sensing The VBUS pin is one of the ways to wake up the clock when the ISP1583 is suspended with bit CLKAON set to logic 0 (clock off option). To detect whether the host is connected or not, that is VBUS sensing, a 1 MΩ resistor and a 1 µF electrolytic or tantalum capacitor must be added to damp the overshoot on plug in.

The RESET_N pin can either be connected to VCC(3V3) (using the internal POR circuit) or externally controlled (by the microcontroller, ASIC, and so on). When VCC(3V3) is directly connected to the RESET_N pin, internal pulse width tPORP will typically be 200 ns. The power-on reset function can be explained by viewing the dips at t2 to t3 and t4 to t5 on the VCC(POR) curve (Figure 10). t0 — The internal POR starts with a HIGH level. t1 — The detector will see the passing of the trip level and a delay element will add another tPORP before it drops to LOW. t2 to t3 — The internal POR pulse will be generated whenever VCC(POR) drops below Vtrip for more than 11 µs. t4 to t5 — The dip is too short (< 11 µs) and the internal POR pulse will not react and will remain LOW. VCC(POR) Vtrip t0 t1 t4 t3 t2 t5 PORP(1) tPORP tPORP 004aab162 (1) PORP = Power-On Reset Pulse. Fig 10. POR timing Figure 11 shows the availability of the clock with respect to the external POR.

Rev. 07 — 22 September 2008 22 of 99 ISP1583 NXP Semiconductors Hi-Speed USB peripheral controller 8.16 Power supply The ISP1583 can be powered by 3.3 V ± 0.3 V, and from 1.65 V to 3.6 V at the interface. For details, see Figure 12. If the ISP1583 is powered by VCC(3V3) = 3.3 V, an integrated 3.3 V-to-1.8 V voltage regulator provides a 1.8 V supply voltage for the internal logic. In sharing mode (that is, when VCC(3V3) is not present and VCC(I/O) is present), all I/O pins are input type, the interrupt pin is connected to ground, and the suspend pin is connected to VCC(I/O). See Table 7. 61 3.3 V ± 0.3 V VCC(3V3) 0.1 µF 0.01 µF 26 VCC(I/O) 1.65 V to 3.6 V 0.01 µF 41 0.1 µF VCC(I/O) 0.01 µF 0.1 µF ISP1583 54 VCC(I/O) 0.01 µF 56 4.7 µF(1) 32 0.1 µF VCC1V8 0.1 µF VCC1V8 0.1 µF 004aaa271 (1) At the VCC input (3.3 V) to the USB controller, if the ripple voltage is less than 20 mV, then 4.7 µF standard electrolytic or tantalum capacitors (tested ESR up to 10 Ω) should be OK at the VCC1V8 output. If the ripple voltage at the input is higher than 20 mV, then use 4.7 µF LOW ESR capacitors (ESR from 0.2 Ω to 2 Ω) at the VCC1V8 output. This is to improve the high-speed signal quality at the USB side. The figure shows the ISP1583BS pinout. For the ISP1583ET, ISP1583ET1 and ISP1583ET2 ballouts, see Table 3. Fig 12.

Therefore, if the application is bus-powered, a 3.3 V regulator needs to be used. [2] VCC(I/O) can range from 1.65 V to 3.6 V. If the application is bus-powered, a voltage regulator must be used.

Fig 13. Power-sharing mode As can be seen in Figure 13, in power-sharing mode, VCC(3V3) is supplied by the output of the 5 V-to-3.3 V voltage regulator. The input to the regulator is from VBUS. VCC(I/O) is supplied through the power source of the system. When the USB cable is plugged in, the ISP1583 goes through the power-on reset cycle. In this mode, OTG is disabled. The processor will experience continuous interrupt because the default status of the interrupt pin when operating in sharing mode with VBUS not present is LOW. To overcome this, implement external VBUS sensing circuitry. The output from the voltage regulator can be connected to pin GPIO of the processor to qualify the interrupt from the ISP1583. Remark: When the core power is applied, the ISP1583 must be reset using the RESET_N pin. The minimum width of the reset pulse width must be 2 ms.

Logic 0 switches off the internal oscillator and PLL when the device goes into suspend mode. The device will consume less power if this bit is set to logic 0. The clock is stopped about 2 ms after bit GOSUSP is set and then cleared. 6 SNDRSU Send Resume: Writing logic 1, followed by logic 0 will generate a 10 ms upstream resume signal.

Mode register: bit description …continued Bit Symbol Description 3 GLINTENA Global Interrupt Enable: Logic 1 enables all interrupts. Individual interrupts can be masked by clearing the corresponding bits in the Interrupt Enable register. When this bit is not set, an unmasked interrupt will not generate an interrupt trigger on the interrupt pin. If global interrupt, however, is enabled while there is any pending unmasked interrupt, an interrupt signal will be immediately generated on the interrupt pin. (If the interrupt is set to pulse mode, the interrupt events that were generated before the global interrupt is enabled will not appear on the interrupt pin.) 2 WKUPCS Wake-up on Chip selection: Logic 1 enables wake-up from suspend mode through a valid register read on the ISP1583. (A read will invoke the chip clock to restart. If you write to the register before the clock gets stable, it may cause malfunctioning.) 1 PWRON Power On: The SUSPEND pin output control. 0 — The SUSPEND pin is HIGH when the ISP1583 is in the suspend state. Otherwise, the SUSPEND pin is LOW. 1 — When the device is woken up from the suspend state, there will be a 1 ms active HIGH pulse on the SUSPEND pin. The SUSPEND pin will remain LOW in all other states. 0 SOFTCT SoftConnect: Logic 1 enables the connection of the 1.5 kΩ pull-up resistor on pin RPU to the DP pin. The status of the chip is shown in Table 26. Table 26. Status of the chip Bus state SoftConnect = on SoftConnect = off VBUS on pull-up resistor on pin DP pull-up resistor on pin DP is removed; suspend interrupt is generated after 3 ms of no bus activity VBUS off pull-up resistor on pin DP is present; pull-up resistor on pin DP is removed; suspend interrupt is generated after suspend interrupt is generated after 3 ms of 3 ms of no bus activity no bus activity 9.2.3 Interrupt Configuration register (address: 10h) This 1-byte register determines the behavior and polarity of the INT output. The bit allocation is shown in Table 27. When the USB SIE receives or generates an ACK, NAK or NYET, it will generate interrupts, depending on three Debug mode fields. CDBGMOD[1:0] — interrupts for control endpoint 0 DDBGMODIN[1:0] — interrupts for DATA IN endpoints 1 to 7 DDBGMODOUT[1:0] — interrupts for DATA OUT endpoints 1 to 7 The Debug mode settings for CDBGMOD, DDBGMODIN and DDBGMODOUT allow you to individually configure when the ISP1583 sends an interrupt to the external microprocessor. Table 29 lists available combinations. Bit INTPOL controls the signal polarity of the INT output: active HIGH or LOW, rising or falling edge. For level-triggering, bit INTLVL must be made logic 0. By setting INTLVL to logic 1, an interrupt will generate a pulse of 60 ns (edge-triggering). ISP1583_7 Product data sheet © NXP B.V. 2008. All rights reserved.

OTG register: bit description Bit Symbol Description[1] 7 to 6 - reserved 5 DP Data Pulsing: Used for data-line pulsing to toggle DP to generate the required data-line pulsing signal. The default value of this bit is logic 0. This bit must be cleared when data-line pulsing is completed. 4 BSESS VALID B-Session Valid: The device can initiate another VBUS discharge sequence after data-line pulsing and VBUS pulsing, and before it clears this bit and detects a session valid. This bit is latched to logic 1 once VBUS exceeds the B-device session valid threshold. Once set, it remains at logic 1. To clear this bit, write logic 1. (The ISP1583 continuously updates this bit to logic 1 when the B-session is valid. If the B-session is valid after it is cleared, it is set back to logic 1 by the ISP1583). 0 — It implies that SRP has failed. To proceed to a normal operation, the device can restart SRP, clear bit OTG or proceed to an error handling process. 1 — It implies that the B-session is valid. The device clears bit OTG, goes into normal operation mode, and sets bit SOFTCT (DP pull-up) in the Mode register. The OTG host has a maximum of 5 s before it responds to a session request. During this period, the ISP1583 may request to suspend. Therefore, the device firmware must wait for some time if it wishes to know the SRP result (success: if there is minimum response from the host within 5 s; failure: if there is no response from the host within 5 s). 3 INIT COND Initial Condition: Write logic 1 to clear this bit. Wait for more than 2 ms and check the bit status. If it reads logic 0, it means that VBUS remains lower than 0.8 V, and DP or DM are at SE0 during the elapsed time. The device can then start a B-device SRP. If it reads logic 1, it means that the initial condition of SRP is violated. So, the device must abort SRP. The bit is set to logic 1 by the ISP1583 when initial conditions are not met, and only writing logic 1 clears the bit. (If initial conditions are not met after this bit has been cleared, it will be set again). Remark: This implementation does not cover the case if an initial SRP condition is violated when this bit is read and data-line pulsing is started. 2 DISCV Discharge VBUS: Set to logic 1 to discharge VBUS. The device discharges VBUS before starting a new SRP. The discharge can take as long as 30 ms for VBUS to be charged less than 0.8 V. This bit must be cleared (write logic 0) before a session end. 1 VP VBUS Pulsing: Used for VBUS pulsing to toggle VP to generate the required VBUS pulsing signal. This bit must be set for more than 16 ms and must be cleared before 26 ms. 0 OTG On-The-Go: 1 — Enables the OTG function. The VBUS sensing functionality will be disabled. 0 — Normal operation. All OTG control bits will be masked. Status bits are undefined. [1] No interrupt is designed for OTG. The VBUS interrupt, however, may assert as a side effect during the VBUS pulsing. When OTG is in progress, the VBUS interrupt may be set because VBUS is charged over the VBUS sensing threshold or the OTG host has turned on the VBUS supply to the device. Even if the VBUS interrupt is found during SRP, the device must complete data-line pulsing and VBUS pulsing before starting the B_SESSION_VALID detection. OTG implementation applies to the device with self-power capability. If the device works in sharing mode, it must provide a switch circuit to supply power to the ISP1583 core during SRP.

Rev. 07 — 22 September 2008 35 of 99 ISP1583 NXP Semiconductors Hi-Speed USB peripheral controller 9.2.4.1 Session Request Protocol (SRP) The ISP1583 can initiate an SRP. The B-device initiates SRP by data-line pulsing, followed by VBUS pulsing. The A-device can detect either data-line pulsing or VBUS pulsing. The ISP1583 can initiate the B-device SRP by performing the following steps: 1. Set the OTG bit to start SRP. 2. Detect initial conditions by following the instructions given in bit INITCOND of the OTG register. 3. Start data-line pulsing: set bit DP of the OTG register to logic 1. 4. Wait for 5 ms to 10 ms. 5. Stop data-line pulsing: set bit DP of the OTG register to logic 0. 6. Start VBUS pulsing: set bit VP of the OTG register to logic 1. 7. Wait for 10 ms to 20 ms. 8. Stop VBUS pulsing: set bit VP of the OTG register to logic 0. 9. Discharge VBUS for about 30 ms: optional by using bit DISCV of the OTG register. 10. Detect bit BSESSVALID of the OTG register for a successful SRP with bit OTG cleared. 11. Once bit BSESSVALID is detected, turn on the SOFTCT bit to start normal bus enumeration. The B-device must complete both data-line pulsing and VBUS pulsing within 100 ms. Remark: When disabling OTG, data-line pulsing bit DP and VBUS pulsing bit VP must be cleared by writing logic 0. 9.2.5 Interrupt Enable register (address: 14h) This register enables or disables individual interrupt sources. The interrupt for each endpoint can individually be controlled using the associated bits IEPnRX or IEPnTX, here n represents the endpoint number. All interrupts can be globally disabled using bit GLINTENA in the Mode register (see Table 24). An interrupt is generated when the USB SIE receives or generates an ACK or NAK on the USB bus. The interrupt generation depends on Debug mode settings of bit fields CDBGMOD[1:0], DDBGMODIN[1:0] and DDBGMODOUT[1:0] in the Interrupt Configuration register. All data IN transactions use the Transmit buffers (TX), which are handled by bits DDBGMODIN[1:0]. All data OUT transactions go through the Receive buffers (RX), which are handled by bits DDBGMODOUT[1:0]. Transactions on control endpoint 0 (IN, OUT and SETUP) are handled by bits CDBGMOD[1:0]. Interrupts caused by events on the USB bus (SOF, suspend, resume, bus reset, set up and high-speed status) can also be individually controlled. A bus reset disables all enabled interrupts, except bit IEBRST (bus reset), which remains logic 1. The Interrupt Enable register consists of 4 bytes. The bit allocation is given in Table 32.

The following registers are indexed: • • • • • • Buffer length Buffer status Control function Data port Endpoint MaxPacketSize Endpoint type For example, to access the OUT data buffer of endpoint 1 using the Data Port register, the Endpoint Index register must first be written with 02h. Remark: The Endpoint Index register and the DMA Endpoint register must not point to the same endpoint, irrespective of IN and OUT. Remark: The delay time from the Write Endpoint Index register to the Read Data Port register must be at least 190 ns. Remark: The delay time from the Write Endpoint Index register to the Write Data Port register must be at least 100 ns. Table 34.

The RX buffer is automatically cleared once the endpoint is completely read. This bit is set only when it is necessary to forcefully clear the buffer. CLBUF Remark: If using double buffer, to clear both the buffers issue the CLBUF command two times. For details on clearing buffers, refer to Ref. 5 “ISP1582/83 and ISP1761 clearing an IN buffer (AN10045)”. 3 VENDP Validate Endpoint: Logic 1 validates data in the TX FIFO of an IN endpoint to send on the next IN token. In general, the endpoint is automatically validated when its FIFO byte count has reached endpoint MaxPacketSize. This bit is set only when it is necessary to validate the endpoint with the FIFO byte count, which is below endpoint MaxPacketSize. Remark: Use either bit VENDP or register Buffer Length to validate endpoint FIFO with FIFO bytes. 2 DSEN Data Stage Enable: This bit controls the response of the ISP1583 to a control transfer. After the completion of the set-up stage, firmware must determine whether a data stage is required. For control OUT, firmware will set this bit and the ISP1583 goes into the data stage. Otherwise, the ISP1583 will NAK the data stage transfer. For control IN, firmware will set this bit before writing data to the TX FIFO and validate the endpoint. If no data stage is required, firmware can immediately set the STATUS bit after the set-up stage. Remark: The DSEN bit is cleared once the OUT token is acknowledged by the device and the IN token is acknowledged by the PC host. This bit cannot be read back and reading this bit will return logic 0. 1 STATUS Status Acknowledge: Only applicable for control IN or OUT. This bit controls the generation of ACK or NAK during the status stage of a SETUP transfer. It is automatically cleared when the status stage is completed, or when a SETUP token is received. No interrupt signal will be generated. 0 — Sends NAK 1 — Sends an empty packet following the IN token (peripheral-to-host) or ACK following the OUT token (host-to-peripheral) Remark: The STATUS bit is cleared to zero once the zero-length packet is acknowledged by the device or the PC host. Remark: Data transfers preceding the status stage must first be fully completed before the STATUS bit can be set. 0 STALL Stall Endpoint: Logic 1 stalls the indexed endpoint. This bit is not applicable for isochronous transfers. Remark: Stalling a data endpoint will confuse the Data Toggle bit about the stalled endpoint because the internal logic picks up from where it is stalled. Therefore, the Data Toggle bit must be reset by disabling and re-enabling the corresponding endpoint (by setting bit ENABLE to logic 0, followed by logic 1 in the Endpoint Type register) to reset the PID. 9.3.3 Data Port register (address: 20h) This 2-byte register provides direct access for a microcontroller to the FIFO of the indexed endpoint. The bit allocation is shown in Table 39. Peripheral-to-host (IN endpoint): After each write action, an internal counter is auto incremented (by two for a 16-bit access, by one for an 8-bit access) to the next location in the TX FIFO. When all bytes are written (FIFO byte count = endpoint MaxPacketSize), the ISP1583_7 Product data sheet © NXP B.V. 2008. All rights reserved. Rev. 07 — 22 September 2008 40 of 99 ISP1583 NXP Semiconductors Hi-Speed USB peripheral controller buffer is automatically validated. The data packet will then be sent on the next IN token. When it is necessary to validate the endpoint whose byte count is less than MaxPacketSize, it can be done using the Control Function register (bit VENDP) or the Buffer Length register. Remark: The buffer can automatically be validated by using the Buffer Length register (see Table 41). Host-to-peripheral (OUT endpoint): After each read action, an internal counter is auto decremented (by two for a 16-bit access, by one for an 8-bit access) to the next location in the RX FIFO. When all bytes are read, buffer contents are automatically cleared. A new data packet can then be received on the next OUT token. Buffer contents can also be cleared using the Control Function register (bit CLBUF), when it is necessary to forcefully clear contents. Remark: The delay time from the Write Endpoint Index register to the Read Data Port register must be at least 190 ns. Remark: The delay time from the Write Endpoint Index register to the Write Data Port register must be at least 100 ns. Table 39.

The bit allocation is given in Table 41. The Buffer Length register is automatically loaded with the FIFO size, when the Endpoint MaxPacketSize register is written (see Table 45). A smaller value can be written when required. After a bus reset, the Buffer Length register is made zero. IN endpoint: When data transfer is performed in multiples of MaxPacketSize, the Buffer Length register is not significant. This register is useful only when transferring data that is not a multiple of MaxPacketSize. The following two examples demonstrate the significance of the Buffer Length register. ISP1583_7 Product data sheet © NXP B.V. 2008. All rights reserved. Rev. 07 — 22 September 2008 41 of 99 ISP1583 NXP Semiconductors Hi-Speed USB peripheral controller Example 1: Consider that the transfer size is 512 bytes and the MaxPacketSize is programmed as 64 bytes, the Buffer Length register need not be filled. This is because the transfer size is a multiple of MaxPacketSize, and MaxPacketSize packets will be automatically validated because the last packet is also of MaxPacketSize. Example 2: Consider that the transfer size is 510 bytes and the MaxPacketSize is programmed as 64 bytes, the Buffer Length register must be filled with 62 bytes just before the microprocessor writes the last packet of 62 bytes. This ensures that the last packet, which is a short packet of 62 bytes, is automatically validated. Use bit VENDP in the Control register if you are not using the Buffer Length register. This is applicable only to PIO mode access. OUT endpoint: The DATACOUNT value is automatically initialized to the number of data bytes sent by the host on each ACK. Remark: When using a 16-bit microprocessor bus, the last byte of an odd-sized packet is output as the lower byte (LSByte). Remark: Buffer Length is valid only after an interrupt is generated for the OUT endpoint. Table 41.

The endpoint index must first be set before accessing this register for the corresponding endpoint. It reflects the status of the double buffered endpoint FIFO. Remark: This register is not applicable to the control endpoint. Remark: For endpoint IN data transfer, firmware must ensure a 200 ns delay between writing of the data packet and reading the Buffer Status register. For endpoint OUT data transfer, firmware must also ensure a 200 ns delay between receiving the endpoint interrupt and reading the Buffer Status register.

The register contains 2 bytes, and the bit allocation is given in Table 45. Each time the register is written, the Buffer Length register of the corresponding endpoint is re-initialized to the FFOSZ field value.

Applies to both high-speed and full-speed operations. The ISP1583 supports all the transfers given in Ref. 1 “Universal Serial Bus Specification Rev. 2.0”. Each programmable FIFO can be independently configured using its Endpoint MaxPacketSize register (R/W: 04h), but the total physical size of all enabled endpoints (IN plus OUT), including set-up token buffer, control IN and control OUT, must not exceed 8192 bytes. 9.3.7 Endpoint Type register (address: 08h) This register sets the endpoint type of the indexed endpoint: isochronous, bulk or interrupt. It also serves to enable the endpoint and configure it for double buffering. Automatic generation of an empty packet for a zero-length TX buffer can be disabled using bit NOEMPKT. The register contains 2 bytes, and the bit allocation is shown in Table 47. Table 47.

Endpoint Type register: bit description Bit Symbol Description 15 to 5 - reserved 4 NOEMPKT No Empty Packet: Logic 0 causes the ISP1583 to return a null length packet for the IN token after the DMA IN transfer is complete. For ATA mode or the DMA IN transfer, which does not require a null length packet after DMA completion, set to logic 1 to disable the generation of the null length packet. 3 ENABLE Endpoint Enable: Logic 1 enables the FIFO of the indexed endpoint. The memory size is allocated as specified in the Endpoint MaxPacketSize register. Logic 0 disables the FIFO. Remark: Stalling a data endpoint will confuse the Data Toggle bit on the stalled endpoint because the internal logic picks up from where it has stalled. Therefore, the Data Toggle bit must be reset by disabling and re-enabling the corresponding endpoint (by setting bit ENABLE to logic 0, followed by logic 1 in the Endpoint Type register) to reset the PID. 2 DBLBUF Double Buffering: Logic 1 enables double buffering for the indexed endpoint. Logic 0 disables double buffering. Remark: When performing a write to two empty buffers, ensure that a minimum of 200 ns delay is provided from the last write of the first buffer to the first write of the second buffer. Otherwise, the first few data bytes may not be written to the second buffer, causing data corruption. 1 to 0 ENDPTYP[1:0] Endpoint Type: These bits select the endpoint type. 00 — not used 01 — Isochronous 10 — Bulk 11 — Interrupt 9.4 DMA registers Two types of Generic DMA transfers and three types of IDE-specified transfers can be done by writing the proper opcode in the DMA Command register. Control bits are given in Table 49 (Generic DMA transfers) and Table 50 (IDE-specified transfers). GDMA read/write (opcode = 00h/01h) — Generic DMA slave mode. Depending on the MODE[1:0] bits set in the DMA Configuration register, the DACK, DIOR or DIOW signal strobes data. These signals are driven by the external DMA controller. GDMA slave mode can operate in either counter mode or EOT-only mode. In counter mode, bit DIS_XFER_CNT in the DMA Configuration register must be set to logic 0. The DMA Transfer Counter register must be programmed before any DMA command is issued. The DMA transfer counter is set by writing from the LSByte to the MSByte (address: 34h to 37h). The DMA transfer count is internally updated only after the MSByte is written. Once the DMA transfer is started, the transfer counter starts decrementing and on reaching 0, bit DMA_XFER_OK is set and an interrupt is generated by the ISP1583. If the DMA master wishes to terminate the DMA transfer, it can issue an EOT signal to the ISP1583. This EOT signal overrides the transfer counter and can terminate the DMA transfer at any time.

Rev. 07 — 22 September 2008 45 of 99 ISP1583 NXP Semiconductors Hi-Speed USB peripheral controller In EOT-only mode, DIS_XFER_CNT must be set to logic 1. Although the DMA transfer counter can still be programmed, it will not have any effect on the DMA transfer. The DMA transfer will start once the DMA command is issued. Any of the following three ways will terminate this DMA transfer: • Detecting an external EOT • Detecting an internal EOT (short packet on an OUT token) • Issuing a GDMA stop command There are three interrupts programmable to differentiate the method of DMA termination: bits INT_EOT, EXT_EOT and DMA_XFER_OK in the DMA Interrupt Reason register (see Table 74). MDMA (master) read/write (opcode = 06h/07h) — Generic DMA master mode. Depending on the MODE[1:0] bits set in the DMA Configuration register, the DACK, DIOR or DIOW signal strobes data. These signals are driven by the ISP1583. In master mode, BURSTCOUNTER[12:0] in the DMA Burst Counter register, DIS_XFER_CNT in the DMA Configuration register and the external EOT signal are not applicable. The DMA transfer counter is always enabled and bit DMA_XFER_OK is set to 1 once the counter reaches 0. MDMA read/write (opcode = 06h/07h) — Multi-word DMA mode for IDE transfers. The specification of this mode can be obtained from Ref. 4 “AT Attachment with Packet Interface Extension (ATA/ATAPI-4), ANSI INCITS 317-1998 (R2003)”. DIOR and DIOW are used as data strobes, while DREQ and DACK serve as handshake signals. Table 49.

Before issuing this command, the task file byte count must be programmed at address 1F4h (LSByte) and 1F5h (MSByte). 0Bh Poll BSY Poll BSY status bit for ATAPI device: Starts repeated PIO read commands to poll the BSY status bit of the ATAPI device. When BSY = 0, polling is terminated and an interrupt is generated. The interrupt can be masked but the interrupt bit will still be set. Therefore, you can manually poll this interrupt bit. 0Ch Read Task Files Read Task Files: Reads all task files. When Task File Index is set to logic 0, this command reads all registers, except 1F0h and 1F7h. If Task File Index is not logic 0, the Task register of the address set in the Task File register will be read. When the reading is completed, an interrupt is generated. The interrupt can be masked off, however, the interrupt bit will still be set. Therefore, you can manually poll this interrupt bit. 0Dh - reserved 0Eh Validate Buffer Validate Buffer (for debugging only): Request from the microcontroller to validate the endpoint buffer, following an ATA-to-USB data transfer. 0Fh Clear Buffer Clear Buffer: Request from the microcontroller to clear the endpoint buffer, after a DMA-to-USB data transfer. Logic 1 clears the TX buffer of the indexed endpoint; the RX buffer is not affected. The TX buffer is automatically cleared once data is sent on the USB bus. This bit is set only when it is necessary to forcefully clear the buffer. Remark: If using double buffer, to clear both the buffers issue the Clear Buffer command two times, that is, set and clear this bit two times. 10h Restart Restart: Request from the microcontroller to move the buffer pointers to the beginning of the endpoint FIFO.

DMA commands …continued Code Name Description 11h Reset DMA Reset DMA: Initializes the DMA core to its power-on reset state. Remark: When the DMA core is reset during the Reset DMA command, the DREQ, DACK, DIOW and DIOR handshake pins will temporarily be asserted. This can confuse the external DMA controller. To prevent this, start the external DMA controller only after the DMA reset. 12h MDMA stop MDMA stop: This command immediately stops the MDMA data transfer. This is applicable for commands 06h and 07h only. 13h GDMA stop GDMA stop: This command stops the GDMA data transfer. Any data in the OUT endpoint that is not transferred by the DMA will remain in the buffer. The FIFO data for the IN endpoint will be written to the endpoint buffer. An interrupt bit will be set to indicate the completion of the DMA Stop command. Remark: For the DMA OUT transfer, if the DMA Burst Counter register is programmed to some value, for example 512 bytes, and if a GDMA Stop command is issued in the middle of a transfer, the transfer will continue until the end of the burst size (512 bytes). Issuing a GDMA Stop command does not allow the ISP1583 to stop in the middle of the burst. It can only be stopped in between bursts. 14h to 20h - reserved 21h Read Task File register 1F1h Read Task File register 1F1h: When reading is completed, an interrupt is generated. 22h Read Task File register 1F2h Read Task File register 1F2h: When reading is completed, an interrupt is generated. 23h Read Task File register 1F3h Read Task File register 1F3h: When reading is completed, an interrupt is generated. 24h Read Task File register 1F4h Read Task File register 1F4h: When reading is completed, an interrupt is generated. 25h Read Task File register 1F5h Read Task File register 1F5h: When reading is completed, an interrupt is generated. 26h Read Task File register 1F6h Read Task File register 1F6h: When reading is completed, an interrupt is generated. 27h Read Task File register 3F6h Read Task File register 3F6h: When reading is completed, an interrupt is generated. 28h Read Task File register 3F7h Read Task File register 3F7h: When reading is completed, an interrupt is generated. 29h to FFh - reserved 9.4.2 DMA Transfer Counter register (address: 34h) This 4-byte register sets up the total byte count for a DMA transfer (DMACR). It indicates the remaining number of bytes left for transfer. The bit allocation is given in Table 54. For IN endpoint — Because there is a FIFO in the ISP1583 DMA controller, some data may remain in the FIFO during the DMA transfer. The maximum FIFO size is 8 bytes, and the maximum delay time for data to be shifted to endpoint buffer is 60 ns. For OUT endpoint — Data will not be cleared from the endpoint buffer, until all the data is read from the DMA FIFO. ISP1583_7 Product data sheet © NXP B.V. 2008. All rights reserved.

It is used to determine the assertion and deassertion of DREQ. 9.5 General registers 9.5.1 Interrupt register (address: 18h) The Interrupt register consists of 4 bytes. The bit allocation is given in Table 82. When a bit is set in the Interrupt register, it indicates that the hardware condition for an interrupt has occurred. When the Interrupt register content is nonzero, the INT output will be asserted corresponding to the Interrupt Enable register. On detecting the interrupt, the external microprocessor must read the Interrupt register and mask it with the corresponding bits in the Interrupt Enable register to determine the source of the interrupt. Each endpoint buffer has a dedicated interrupt bit (EPnTX, EPnRX). In addition, various bus states can generate an interrupt: resume, suspend, pseudo SOF, SOF and bus reset. The DMA controller only has one interrupt bit: the source for a DMA interrupt is shown in the DMA Interrupt Reason register (see Table 72 and Table 73). ISP1583_7 Product data sheet © NXP B.V. 2008.

In this case, when the chip resumes, the Unlock Device command must first be issued to this register before attempting to write to the rest of the registers. This is done by writing unlock code (AA37h) to this register. The bit allocation of the Unlock Device register is given in Table 90. Table 90.

When bit PWRON in the Mode register is logic 1, the chip is powered. In such a case, you do not need to issue the Unlock command because the microprocessor is powered and therefore, the RW_N/RD_N, DS_N/WR_N and CS_N signals maintain their states. When bit PWRON is logic 0, the RW_N/RD_N, DS_N/WR_N and CS_N signals are floating because the microprocessor is not powered. To protect the ISP1583 registers from being corrupted during suspend, register write is locked when the chip goes into suspend. Therefore, you need to issue the Unlock command to unlock the ISP1583 registers. 9.5.6 Test Mode register (address: 84h) This 1-byte register allows the firmware to set the DP and DM pins to predetermined states for testing purposes. The bit allocation is given in Table 92. Remark: Only one bit can be set at a time. Either bit FORCEHS or FORCEFS must be set to logic 1 at a time. Of the four bits PRBS, KSTATE, JSTATE and SE0_NAK only one bit must be set at a time. This must be implemented for the Hi-Speed USB logo compliance testing. To exit test mode, power cycle is required. ISP1583_7 Product data sheet © NXP B.V. 2008. All rights reserved.

Minimum timing requirements for Tcy1, tw1 and tw2 must all be met. As Tcy1(min) is greater than the sum of tw1(min) and tw2(min), a host implementation must lengthen tw1 and/or tw2 to ensure that Tcy1 is equal to or greater than the value reported in the IDENTIFY DEVICE data. A device implementation shall support any legal host implementation. [2] td2 specifies the time after DIOR is negated, when the data bus is no longer driven by the device (3-state). [3] If READY/IORDY is LOW at tsu4, the host waits until READY/IORDY is made HIGH before the PIO cycle is completed. In that case, tsu5 must be met for reading (tsu3 does not apply). When READY/IORDY is HIGH at tsu4, tsu3 must be met for reading (tsu5 does not apply). ISP1583_7 Product data sheet © NXP B.V. 2008. All rights reserved.

(2) The data bus width depends on the PIO access command used. The Task File register access uses 8 bits (DATA[7:0]), except for Task File register 1F0 that uses 16 bits (DATA[15:0]). DMA commands 04h and 05h also use a 16-bit data bus. (3) The device can negate READY/IORDY to extend the PIO cycle with wait states. The host determines whether or not to extend the current cycle after tsu4, following the assertion of DIOR or DIOW. The following three cases are distinguished: a) Device keeps READY/IORDY released (high-impedance): no wait state is generated. b) Device negates READY/IORDY during tsu4, but re-asserts READY/IORDY before tsu4 expires: no wait state is generated. c) Device negates READY/IORDY during tsu4 and keeps READY/IORDY negated for at least 5 ns after tsu4 expires: a wait state is generated. The cycle is completed as soon as READY/IORDY is re-asserted. For extended read cycles (DIOR asserted), the read data on lines DATAn must be valid at td1 before READY/IORDY is asserted. (4) DIOR and DIOW have a programmable polarity: shown here as active LOW signals. Fig 31. PIO mode timing ISP1583_7 Product data sheet © NXP B.V. 2008. All rights reserved.

A more in-depth account of soldering ICs can be found in Application Note AN10365 “Surface mount reflow soldering description”. 17.1 Introduction to soldering Soldering is one of the most common methods through which packages are attached to Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both the mechanical and the electrical connection. There is no single soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high densities that come with increased miniaturization. 17.2 Wave and reflow soldering Wave soldering is a joining technology in which the joints are made by solder coming from a standing wave of liquid solder. The wave soldering process is suitable for the following: • Through-hole components • Leaded or leadless SMDs, which are glued to the surface of the printed circuit board Not all SMDs can be wave soldered. Packages with solder balls, and some leadless packages which have solder lands underneath the body, cannot be wave soldered. Also, leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered, due to an increased probability of bridging. The reflow soldering process involves applying solder paste to a board, followed by component placement and exposure to a temperature profile. Leaded packages, packages with solder balls, and leadless packages are all reflow solderable. Key characteristics in both wave and reflow soldering are: • • • • • • Board specifications, including the board finish, solder masks and vias Package footprints, including solder thieves and orientation The moisture sensitivity level of the packages Package placement Inspection and repair Lead-free soldering versus SnPb soldering 17.3 Wave soldering Key characteristics in wave soldering are: • Process issues, such as application of adhesive and flux, clinching of leads, board transport, the solder wave parameters, and the time during which components are exposed to the wave • Solder bath specifications, including temperature and impurities ISP1583_7 Product data sheet © NXP B.V. 2008. All rights reserved. Rev. 07 — 22 September 2008 89 of 99 ISP1583 NXP Semiconductors Hi-Speed USB peripheral controller 17.4 Reflow soldering Key characteristics in reflow soldering are: • Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to higher minimum peak temperatures (see Figure 42) than a SnPb process, thus reducing the process window • Solder paste printing issues including smearing, release, and adjusting the process window for a mix of large and small components on one board • Reflow temperature profile; this profile includes preheat, reflow (in which the board is heated to the peak temperature) and cooling down. It is imperative that the peak temperature is high enough for the solder to make reliable solder joints (a solder paste characteristic). In addition, the peak temperature must be low enough that the packages and/or boards are not damaged. The peak temperature of the package depends on package thickness and volume and is classified in accordance with Table 111 and 112 Table 111. SnPb eutectic process (from J-STD-020C) Package thickness (mm) Package reflow temperature (°C) Volume (mm3) < 350 ≥ 350 < 2.5 235 220 ≥ 2.5 220 220 Table 112.

Studies have shown that small packages reach higher temperatures during reflow soldering, see Figure 42. ISP1583_7 Product data sheet © NXP B.V. 2008. All rights reserved.
