EZ-USB FX3 also provides interfaces to connect to serial peripherals such as UART, SPI, I2C, and I2S. Cypress EZ-USB FX3 is the next generation USB3.0 peripheral controller providing highly integrated and flexible features that enable developers to add USB3.0 functionality to any system. EZ-USB FX3 comes with the easy to use EZ-USB tools providing a complete solution for fast application development. The software development kit comes with application examples for accelerating time to market. EZ-USB FX3 has a fully configurable, parallel, General Programmable Interface called GPIF II, which can connect to any processor, ASIC, or FPGA. The General Programmable Interface GPIF II is an enhanced version of the GPIF in FX2LP, Cypress’s flagship USB2.0 product. It provides easy and glueless connectivity to popular interfaces such as asynchronous SRAM, asynchronous and synchronous Address Data Multiplexed interface, parallel ATA, and so on. EZ-USB FX3 is fully compliant to USB3.0 v1.0 specification and is also backward compatible with USB2.0. It is also complaint with the Battery Charging Specification v1.1 and USB2.0 OTG Specification v2.0. Application Examples EZ-USB FX3 has integrated USB3.0 and USB2.0 physical layer (PHYs) along with a 32-bit ARM926EJ-S microprocessor for powerful data processing and for building custom applications. It implements an ingenious architecture which enables data transfers of 320 MBps[1] from GPIF II to USB interface. Figure 1 and Figure 2 show typical application diagrams for EZ-USB FX3. Figure 1 shows a typical application diagram in which EZ-USB FX3 functions as a co-processor and connects to an external processor responsible for various system level functions. Figure 2 shows a typical application diagram when EZ-USB FX3 functions as the main processor in the system. An integrated USB2.0 OTG controller enables applications that need dual role usage scenarios, for example EZ-USB FX3 may function as OTG Host to MSC and HID class devices. Figure 1.

USB Interface Signals EZ-USB FX3 EZ-USB FX3 supports USB peripheral functionality compliant with USB 3.0 Specification Revision 1.0 and is also backward compatible with the USB 2.0 Specification. VBATT VBUS OTG_ID SSRXSSRX+ SSTXSSTX+ DD+ EZ-USB FX3 is compliant with On-The-Go Supplement Revision 2.0. It supports Hi-Speed, Full-Speed, and Low Speed OTG dual role device capability. It is SuperSpeed, High-Speed, and Full-Speed capable as a peripheral and High-Speed, Full-Speed, and Low-Speed capable as a host. EZ-USB FX3 supports Carkit Pass-Through UART functionality on USB D+/D- lines based on the CEA-936A specification. USB Interface USB Interface EZ-USB FX3 supports up to 16 IN and 16 OUT endpoints. EZ-USB FX3 fully supports the USB3.0 Streams feature. It also supports USB Attached SCSI (UAS) device class to optimize mass storage access performance. As a USB peripheral, EZ-USB FX3 supports UAS, USB Video Class (UVC), Mass Storage Class (MSC), and Media Transfer Protocol (MTP) USB peripheral classes. As a USB peripheral, all other device classes are supported only in pass through mode when handled entirely by a host processor external to the device. As an OTG host, EZ-USB FX3 supports MSC and HID device classes. When the USB port is not in use, the PHY and transceiver may be disabled for power savings. Document Number 001-52136 Rev. *I OTG EZ-USB FX3 is compliant with the On-The-Go (OTG) Specification Revision 2.0 . In OTG mode, EZ-USB FX3 supports both A and B device mode and supports Control, Interrupt, Bulk, and Isochronous data transfers. EZ-USB FX3 requires an external charge pump (either stand alone or integrated into a PMIC) to power VBUS in OTG A-device mode. The Target Peripheral List for OTG host implementation consists of MSC and HID class devices. Attach Detection Protocol (ADP) is not supported by EZ-USB FX3. Page 4 of 38 PRELIMINARY CYUSB3014 OTG Connectivity VBUS Overvoltage Protection In OTG mode, EZ-USB FX3 can be configured to be A, B, or dual role device. It is able to connect to: ■ ACA device ■ Targeted USB peripheral ■ SRP capable USB peripheral The maximum input voltage on EZ-USB FX3's VBUS pin is 6V. A charger can supply up to 9V on VBUS, in this case, it is necessary to have an external Over voltage Protection (OVP) device to protect EZ-USB FX3 from damage on VBUS. Figure 4 shows the system application diagram with an OVP device connected on VBUS. Please refer to Table 7DC Specifications for the operating range of VBUS and VBATT. ■ HNP capable USB peripheral Figure 4. System Diagram with OVP Device For VBUS ■ OTG host ■ HNP capable host ■ OTG device EZ-Dtect EZ-USB FX3 supports USB Charger and accessory detection (EZ-Dtect). The charger detection mechanism is in compliance with the Battery Charging Specification Revision 1.1. In addition to supporting this version of the specification EZ-USB FX3 also provides hardware support to detect the resistance values on the ID pin. The following are the resistance ranges that EZ-USB FX3 can detect: ■ Less than 10 ■ Less than 1 k ■ 65 k to 72 k ■ 35 kto 39 k ■ 99.96 k to 104.4 k (102 k2%) ■ 119 k to 132 k ■ Higher than 220 k ■ 431.2 k to 448.8 k (440 k2%) VIO5 AVDD VDD VIO4 CVDDQ VIO3 EZ-USB FX3 OVP device 2 SSRXSSRX+ SSTXSSTX+ DD+ 3 4 5 6 7 8 9 VBUS OTG_ID USB-Port 1 USB Connector When first plugged into USB, EZ-USB FX3 enumerates automatically with the Cypress Vendor ID (0x04B4) and downloads firmware and USB descriptors over the USB interface. The downloaded firmware executes a electrical disconnect and connect. EZ-USB FX3 enumerates again, this time as a device defined by the downloaded information. This patented two step process called ReNumeration happens instantly when the device is plugged in. VIO2 Because EZ-USB FX3's configuration is soft, one chip can take on the identities of multiple distinct USB devices. VIO1 ReNumeration U3TXVDDQ U3RXVDDQ POWER SUBSYSTEM GND Carkit UART Mode The USB interface supports Carkit UART mode (UART over D+/D-) for non-USB serial data transfer. This is based on the CEA-936A specification. In Carkit UART mode, the output signaling voltage is 3.3V. When configured for Carkit UART mode, TXD of UART (output) is mapped to D- line, and RXD of UART (input) is mapped to D+ line. In Carkit mode, EZ-USB FX3 disables the USB transceiver and D+ and D- pins serve as pass through pins to connect to the UART of the host processor. The Carkit UART signals may be routed to the GPIF II interface or to GPIO[48] and GPIO[49] as shown in Figure 5 on page 6. A rate of up to 9600 bps is supported by EZ-USB FX3 in this mode. EZ-USB FX3's charger detection feature detects a dedicated wall charger, Host/Hub charger, and Host/Hub. Document Number 001-52136 Rev. *I Page 5 of 38 PRELIMINARY CYUSB3014 Figure 5.

This interface enables functionality similar to but more advanced than FX2LP's GPIF and Slave FIFO interfaces. Note: Access to all 32 buffer is also supported over Slave FIFO interface. For details, please contact Cypress Applications Support. Figure 6. Slave FIFO Interface SLCS# PKTEND FLAGB FLAGA The GPIF II is a programmable state machine that enables a flexible interface that may function either as a master or slave in industry standard or proprietary interfaces. Both parallel and serial interfaces may be implemented with GPIF II. External Processor The features of the GPIF II are summarized as follows: A[1:0] D[31:0] EZ-USB FX3 SLWR# ■ Functions as master or slave SLRD# ■ Provides 256 firmware programmable states SLOE# ■ Supports 8 bit, 16 bit and 32 bit parallel data bus ■ Enables interface frequencies up to 100 MHz. ■ Supports 14 configurable control pins when 32 bit data bus is used. All control pins can be either input/output or bidirectional. CPU ■ Supports 16 configurable control pins when 16/8 data bus is used. All control pins can be either input/output or bidirectional. EZ-USB FX3 has an on chip 32-bit, 200 MHz ARM926EJ-S core CPU. The core has direct access to 16kB of Instruction Tightly Coupled Memory (TCM) and 8kB of Data TCM. The ARM926EJ-S core provides a JTAG interface for firmware debugging. GPIFII state transitions occur based on control input signals. The control output signals are driven as a result of GPIFII state transitions. The behavior of the GPIFII state machine is defined by a GPIFII descriptor. The GPIFII descriptor is designed such that the required interface specifications are met. 8kB of memory (separate from the 512kB of embedded SRAM) is dedicated as GPIF II Waveform memory where the GPIF II descriptor is stored in a specific format. Cypress’ GPIFII Designer Tool enables fast development of GPIFII descriptors and includes examples for common interfaces. Example implementations of GPIF II are the Asynchronous Slave FIFO and Synchronous Slave FIFO interfaces. Slave FIFO interface The Slave FIFO interface signals are shown in Figure 6. This interface allows an external processor to directly access upto 4 buffers internal to EZ-USB FX3. Further details of the Slave FIFO interface are described on page 19 Document Number 001-52136 Rev. *I Note: Multiple Flags may be configured. EZ-USB FX3 also integrates 512 kB of embedded SRAM for code and data, and 8kB of Instruction cache and Data cache. EZ-USB FX3 implements highly efficient and flexible DMA connectivity between the various peripherals (i.e. USB, GPIF II, I2S, SPI,UART), requiring firmware to only configure data accesses between peripherals which are then managed by the DMA fabric. EZ-USB FX3 allows for easy application development on industry standard development tools for ARM926EJ-S. Examples of EZ-USB FX3 firmware are available with the Cypress EZ-USB FX3 Development Kit. Software APIs that can be ported to an external processor are available with the Cypress EZ-USB FX3 Software Development Kit. Page 6 of 38 PRELIMINARY CYUSB3014 JTAG Interface EZ-USB FX3’s JTAG interface provides a standard five-pin interface for connecting to a JTAG debugger to debug firmware through the CPU-core's on-chip-debug circuitry. Industry standard debugging tools for the ARM926EJ-S core can be used for EZ-USB FX3 application development. Other Interfaces EZ-USB FX3 supports the following serial peripherals: Both SCL and SDA signals of the I2C interface require external pull-up resistors. The pull-up resistors must be connected to VIO5. I2S Interface EZ-USB FX3 has an I2S port to support external audio codec devices. EZ-USB FX3 functions as I2S Master as transmitter only. The I2S interface consists of four signals: clock line (I2S_CLK), serial data line (I2S_SD), word select line (I2S_WS), and master system clock (I2S_MCLK). EZ-USB FX3 can generate the system clock as an output on I2S_MCLK or accept an external system clock input on I2S_MCLK. ■ UART ■ I2C The sampling frequencies supported by the I2S interface are 32 kHz, 44.1 kHz, and 48 kHz. ■ I2S SPI Interface ■ SPI The SPI, UART and I2S interfaces are multiplexed on the Serial Peripheral port. EZ-USB FX3 supports an SPI Master interface on the Serial Peripherals port.The maximum frequency of operation is 33 MHz. UART Interface The SPI controller supports four modes of SPI communication with Start-Stop clock. The SPI controller is a single master controller with a single automated SSN control. It supports transaction sizes from 4-bit to 32 bits long. The UART interface of EZ-USB FX3 supports full duplex communication. It includes the signals noted in Table 1. Boot Options Table 1. UART Interface Signals EZ-USB FX3 can load boot images from various sources, selected by the configuration of the PMODE pins. The boot options for EZ-USB FX3 are listed as follows: The Pin List on page 32 shows details of how these interfaces are multiplexed. Signal Description TX Output signal RX Input signal CTS Flow control RTS Flow control The UART is capable of generating a range of baud rates from 300 bps to 4608 Kbps selectable by the firmware. 2 I C Interface I2C I 2C EZ-USB FX3 has an interface compatible with the Bus Specification Revision 3. EZ-USB FX3’s I2C interface is capable of operating as I2C Master only, hence may be used to communicate with other I2C slave devices. For example, EZ-USB FX3 may boot from an EEPROM connected to the I2C interface, as a selectable boot option. I2C EZ-USB FX3’s Master Controller also supports Multi-master mode functionality. The power supply for the I2C interface is VIO5, which is a separate power domain from the other serial peripherals. This is to allow the I2C interface the flexibility to operate at a different voltage than the other serial interfaces. ■ Boot from USB ■ Boot from I2C ■ Boot from SPI (SPI devices supported are M25P16 (16 Mbit), M25P80 (8 Mbit), and M25P40 (4 Mbit)) or their equivalents ■ Boot from GPIF II ASync ADMUX mode ■ Boot from GPIF II Sync ADMUX mode ■ Boot from GPIF II ASync SRAM mode Table 2.

When VIO5 is 1.2V, the maximum operating frequency supported is 100 kHz. When VIO5 is 1.8 V, 2.5 V or 3.3 V, the operating frequencies supported are 400 kHz and 1 MHz. Note 2. F indicates Floating. Document Number 001-52136 Rev. *I Page 7 of 38 PRELIMINARY CYUSB3014 Reset Clocking Hard Reset EZ-USB FX3 allows either a crystal to be connected between the XTALIN and XTALOUT pins or an external clock to be connected at the CLKIN pin. A hard reset is initiated by asserting the Reset# pin on EZ-USB FX3. The specific reset sequence and timing requirements are detailed in Figure 17 and Table 15. Soft Reset Soft Reset involves the processor setting the appropriate bits in the PP_INIT control register. There are two types of Soft Reset: ■ CPU Reset - The CPU Program Counter is reset. Firmware does not need to be reloaded following a CPU Reset. ■ Whole Device Reset - This reset is identical to Hard Reset. The firmware must be reloaded following a Whole Device Reset. Crystal frequency supported is 19.2 MHz, while the external clock frequencies supported are 19.2, 26, 38.4, and 52 MHz. EZ-USB FX3 has an on-chip oscillator circuit that uses an external 19.2 MHz (±100 ppm) crystal (when the crystal option is used). The FSLC[2:0] pins must be configured appropriately to select the crystal option/clock frequency option. The configuration options are shown in Table 3. Clock inputs to EZ-USB FX3 must meet the phase noise and jitter requirements specified in Table 4. The input clock frequency is independent of the clock/data rate of EZ-USB FX3 core or any of the device interfaces (including P-Port and S-Port). The internal PLL applies the appropriate clock multiply option depending on the input frequency. Table 3.

The watchdog timer can be used to interrupt the ARM926EJ-S core, auto wakeup EZ-USB FX3 in Standby mode and reset the ARM926EJ-S core. The watch dog timer runs off a 32 kHz clock. This 32 kHz clock may optionally be supplied from an external source on a dedicated pin of EZ-USB FX3. The watchdog timer can be disabled by firmware.

Contact Cypress Applications/Marketing for details. EZ-USB FX3 meets EMI requirements outlined by FCC 15B (USA) and EN55022 (Europe) for consumer electronics. EZ-USB FX3 can tolerate reasonable EMI conducted by aggressor outlined by these specifications and continue to function as expected. Digital I/Os EZ-USB FX3 provides firmware controlled pull up or pull down resistors internally on all digital I/O pins. The pins can be pulled high through an internal 50 k resistor or can be pulled low through an internal 10 k resistor to prevent the pins from floating. The I/O pins may have the following states: ■ Tristated (High-Z) ■ Weak Pull up (via internal 50 k) ■ Pull down (via internal 10 k) ■ Hold (I/O hold its value) when in low power modes ■ The JTAG signals TDI, TMC, TRST# signals have fixed 50 k internal pull-ups & the TCK signal has a fixed 10 kpull down resistor. GPIOs EZ-USB allows for a flexible pin configuration both on the GPIF II and the serial peripheral interfaces. Any unused control pins on the GPIF II interface may be used as GPIOs. Similarly, any unused pins on the serial peripheral interfaces may be configured as GPIOs. Please refer to the Pin List for pin configuration options.

After a propagation delay of tco (measured from the rising edge of PCLK) the new data value is present. N is the first data value read from the FIFO. To have data on the FIFO data bus, SLOE must also be asserted. Note For burst mode, the SLRD# and SLOE# are left asserted during the entire duration of the read.
