GPIF™ II Designer
The GPIF II Designer is a graphical software that allows designers to configure the GPIF II interface of the EZ-USB FX3 USB 3.0
Device Controller.
The tool allows users the ability to select from one of five Cypress supplied interfaces, or choose to create their own GPIF II interface
from scratch. Cypress has supplied industry standard interfaces such as asynchronous and Synchronous Slave FIFO, Asynchronous
and Synchronous SRAM, and Asynchronous SRAM. Designers who already have one of these pre-defined interfaces in their system
can simply select the interface of choice, choose from a set of standard parameters such as bus width (x8, 16, x32) endianess, clock
settings, and compile the interface. The tool has a streamlined three step GPIF interface development process for users who need a
customized interface. Users are able to first select their pin configuration and standard parameters. Secondly, they can design a virtual
state machine using configurable actions. Finally, users can view output timing to verify that it matches the expected timing. Once the
three step process is complete, the interface can be compiled and integrated with FX3.

Functional Overview
Cypress’s EZ-USB FX3S is the next-generation USB 3.0
peripheral controller, providing integrated and flexible features.
FX3S has a fully configurable, parallel, general programmable
interface called GPIF II, which can connect to any processor,
ASIC, or FPGA. GPIF II is an enhanced version of the GPIF in
FX2LP, Cypress’s flagship USB 2.0 product. It provides easy and
glueless connectivity to popular interfaces, such as
asynchronous SRAM, asynchronous and synchronous address
data multiplexed interfaces, and parallel ATA. FX3S has
integrated the USB 3.0 and USB 2.0 physical layers (PHYs)
along with a 32-bit ARM926EJ-S microprocessor for powerful
data processing and for building custom applications. It
implements an architecture that enables 185-MBps data transfer
from GPIF II to the USB interface.
FX3S features an integrated storage controller and can support
up to two independent mass storage devices on its storage ports.
It can support SD 3.0 and eMMC 4.41 memory cards. It can also
support SDIO 3.0 on these ports. FX3 has built in RAID with
support for RAID 0 and RAID 1 using either SD or eMMC.
An integrated USB 2.0 OTG controller enables applications in
which FX3S may serve dual roles; for example, EZ-USB FX3S
may function as an OTG Host to MSC as well as HID-class
devices. FX3S contains 512 KB or 256 KB of on-chip SRAM for
code and data. EZ-USB FX3S also provides interfaces to
connect to serial peripherals such as UART, SPI, I2C, and I2S.
FX3S comes with application development tools. The software
development kit comes with application examples for
accelerating time to market.
FX3S complies with the USB 3.0 v1.0 specification and is also
backward compatible with USB 2.0. It also complies with
USB 2.0 OTG Specification v2.0.
Application Examples
In a typical application (see Figure 1), FX3S functions as a
coprocessor and connects to an external processor, which
manages system-level functions. Figure 2 shows a typical
application diagram when FX3S functions as the main
processor.

OTG
FX3S is compliant with the OTG Specification Revision 2.0. In
the OTG mode, FX3S supports both A and B device modes and
supports Control, Interrupt, Bulk, and Isochronous data
transfers.
FX3S requires an external charge pump (either standalone or
integrated into a PMIC) to power VBUS in the OTG A-device
mode.
The Target Peripheral List for OTG host implementation consists
of MSC- and HID-class devices.
FX3S does not support Attach Detection Protocol (ADP).
As an OTG host, FX3S supports MSC and HID device classes.

ReNumeration
Because of FX3S’s soft configuration, one chip can take on the
identities of multiple distinct USB devices.
When first plugged into USB, FX3S enumerates automatically
with the Cypress Vendor ID (0x04B4) and downloads firmware
and USB descriptors over the USB interface. The downloaded
firmware executes an electrical disconnect and connect. FX3S
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.
VBUS Overvoltage Protection
The maximum input voltage on FX3S’s VBUS pin is 6 V. A
charger can supply up to 9 V on VBUS. In this case, an external
overvoltage protection (OVP) device is required to protect FX3S
from damage on VBUS. Figure 4 shows the system application
diagram with an OVP device connected on VBUS. Refer to the
DC Specifications table for the operating range of VBUS and
VBATT.

Carkit UART Mode
The USB interface supports the Carkit UART mode (UART over
D+/D–) for non-USB serial data transfer. This mode is based on
the CEA-936A specification.
In the Carkit UART mode, the output signaling voltage is 3.3 V.
When configured for the Carkit UART mode, TXD of UART
(output) is mapped to the D– line, and RXD of UART (input) is
mapped to the D+ line.
In the Carkit UART mode, FX3S 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.
In this mode, FX3S supports a rate of up to 9600 bps.

The following sections describe these P-Port interfaces.
GPIF II
The high-performance GPIF II interface enables functionality
similar to, but more advanced than, FX2LP’s GPIF and Slave
FIFO interfaces.
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.
Here are a list of GPIF II features:
■
Functions as master or slave
■
Provides 256 firmware programmable states
■
Supports 8-bit and 16-bit parallel data bus
■
Enables interface frequencies up to 100 MHz
■
Supports 16 configurable control pins when a 16/8 data bus is
used. All control pins can be either input/output or bi-directional.
GPIF II state transitions are based on control input signals. The
control output signals are driven as a result of the GPIF II state
transitions. The INT# output signal can be controlled by GPIF II.
Refer to the GPIFII Designer tool. The GPIF II state machine’s
behavior is defined by a GPIF II descriptor. The GPIF II
descriptor is designed such that the required interface
specifications are met. 8 kB of memory (separate from the
512 kB of embedded SRAM) is dedicated to the GPIF II
waveform where the GPIF II descriptor is stored in a specific
format.

SLRD#
Note: Multiple Flags may be configured.
Asynchronous SRAM
This interface consists of standard asynchronous SRAM
interface signals as shown in Figure 7. This interface is used to
access both the configuration registers and buffer memory of
FX3S. Both single-cycle and burst accesses are supported by
asynchronous interface signals.
The most significant address bit, A[7], determines whether the
configuration registers or buffer memory are accessed. When
the configuration registers are selected by asserting the address
bit A[7], the address bus bits A[6:0] point to a configuration
register. When A[7] is deasserted, the buffer memory is
accessed as indicated by the P-Port DMA transfer register and
the transfer size is determined by the P-Port DMA transfer size
register.
Application processors with a DMA controller that use address
auto-increment during DMA transfers, can override this by
connecting any higher-order address line (such as
A[15]/A[23]/A[31]) of the application processor to FX3S’s A[7].
In the asynchronous SRAM mode, when reading from a buffer
memory, FX3S supports two methods of reading out next data
from the buffer. The next data may be read out on the rising edge
of OE# or by toggling the least significant address bit A[0].
In this mode, the P-Port interface works with a 32.5-ns minimum
access cycle providing an interface data rate of up to 61.5 MB
per second.

For read operations, assert both CE# and OE#.
For write operations, assert both CE# and WE#. OE# is “Don’t

phase of the write cycle). The input data is latched on the rising
edge of WE# or CE#, whichever occurs first. Latch the addresses
prior to the write operation by toggling Address Valid (ADV#).
Assert Address Valid (ADV#) during the address phase of the
write operation, as shown in Figure 19 on page 30.
ADV# must be LOW during the address phase of a read/write
operation. ADV# must be HIGH during the data phase of a
read/write operation, as shown in Figure 18 on page 30 and
Figure 19 on page 30.
FX3S’s P-Port supports a synchronous address/data
multiplexed interface. This operates at an interface frequency of
up to 100 MHz and supports a 16-bit data bus.
The RDY output signal from the FX3S device indicates a data
valid for read transfers and is acknowledged for write transfers.

CPU
FX3S has an on-chip 32-bit, 200-MHz ARM926EJ-S core CPU.
The core has direct access to 16 kB of Instruction Tightly
Coupled Memory (TCM) and 8 kB of Data TCM. The
ARM926EJ-S core provides a JTAG interface for firmware
debugging.
FX3S offers the following advantages:
■
Integrates 512 KB of embedded SRAM for code and data and
8 KB of Instruction cache and Data cache.
■
Implements efficient and flexible DMA connectivity between the
various peripherals (such as, USB, GPIF II, I2S, SPI, UART),
requiring firmware only to configure data accesses between
peripherals, which are then managed by the DMA fabric.
■
Allows easy application development on industry-standard
development tools for ARM926EJ-S.
Examples of the FX3S firmware are available with the Cypress
EZ-USB FX3S Development Kit. Software APIs that can be
ported to an external processor are available with the Cypress
EZ-USB FX3S Software Development Kit.
Storage Port (S-Port)
FX3S has two independent storage ports (S0-Port and S1-Port).
Both storage ports support the following specifications:
■
MMC-system specification, MMCA Technical Committee,
Version 4.41
■
SD specification, Version 3.0
■
SDIO host controller compliant with SDIO Specification Version
3.00
Both storage ports support the following features:
SD/MMC Clock Stop
FX3S supports the stop clock feature, which can save power if
the internal buffer is full when receiving data from the
SD/MMC/SDIO.
SD_CLK Output Clock Stop
During the data transfer, the SD_CLK clock can be enabled (on)
or disabled (stopped) at any time by the internal flow control
mechanism.
■
100 MHz – For a card with 0- to 100-MHz frequency
If the DDR mode is selected, data is clocked on both the rising
and falling edge of the SD clock. DDR clocks run up to 52 MHz.
Card Insertion and Removal Detection
FX3S supports the two-card insertion and removal detection
mechanisms.
■
Use of SD_D[3] data: During system design, this signal must
have an external 470-k pull-down resistor connected to
SD_D[3]. SD cards have an internal 10-k pull-up resistor.
When the card is inserted or removed from the SD/MMC
connector, the voltage level at the SD_D[3] pin changes and
triggers an interrupt to the CPU. The older generations of MMC
cards do not support this card detection mechanism.
■
Use of the S0/S1_INS pin: Some SD/MMC connectors facilitate
a micro switch for card insertion/removal detection. This micro
switch can be connected to S0/S1_INS. When the card is
inserted or removed from the SD/MMC connector, it turns the
micro switch on and off. This changes the voltage level at the
pin that triggers the interrupt to the CPU. The card-detect micro
switch polarity is assumed to be the same as the write-protect
micro switch polarity. A low indicates that the card is inserted.
This S0/S1_INS pin is shared between the two S-Ports.
Register configuration determines which port gets to use this
pin. This pin is mapped to the S1VDDQ power domain; if
S0VDDQ and S1VDDQ are at different voltage levels, this pin
cannot be used as S1_INS.
Write Protection (WP)
The S0_WP/S1_WP (SD Write Protection) on S-Port is used to
connect to the WP micro switch of SD/MMC card connector. This
pin internally connects to a CPU-accessible GPIO for firmware
to detect the SD card write protection.
SDIO Interrupt
The SDIO interrupt functionality is supported as specified in the
SDIO specification Version 2.00 (January 30, 2007).
SDIO Read-Wait Feature
FX3S supports the optional read-wait and suspend-resume
features as defined in the SDIO specification Version 2.00
(January 30, 2007).
SD_CLK output frequency is dynamically configurable using a
clock divisor from a system clock. The clock choice for the divisor
is user-configurable through a register. For example, the
following frequencies may be configured:
■
400 kHz – For the SD/MMC card initialization
■
20 MHz – For a card with 0- to 20-MHz frequency
■
24 MHz – For a card with 0- to 26-MHz frequency
■
48 MHz – For a card with 0- to 52-MHz frequency
(48-MHz frequency on SD_CLK is supported when the clock
input to FX3S is 19.2 MHz or 38.4 MHz)
■
52 MHz – For a card with 0- to 52-MHz frequency
(52-MHz frequency on SD_CLK is supported when the clock
input to FX3S is 26 MHz or 52 MHz)

JTAG Interface
I2C Interface
FX3S’s JTAG interface has a standard five-pin interface to
connect to a JTAG debugger in order to debug firmware through
the CPU-core’s on-chip-debug circuitry.
FX3S’s I2C interface is compatible with the I2C Bus Specification
Revision 3. This I2C interface is capable of operating only as I2C
master; therefore, it may be used to communicate with other I2C
slave devices. For example, FX3S may boot from an EEPROM
connected to the I2C interface, as a selectable boot option.
Industry-standard debugging tools for the ARM926EJ-S core
can be used for the FX3S application development.
Other Interfaces
FX3S supports the following serial peripherals:
■
UART
■
I2C
2
■I S
■
SPI
The SPI, UART, and I2S interfaces are multiplexed on the serial
peripheral port.
UART Interface
The UART interface of FX3S supports full-duplex
communication. It includes the signals noted in Table 1.
Table 1. UART Interface Signals
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. If flow control
is enabled, then FX3S’s UART only transmits data when the CTS
input is asserted. In addition to this, FX3S's UART asserts the
RTS output signal, when it is ready to receive data.
Document Number: 001-84160 Rev. *J
FX3S’s I2C 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
gives the I2C interface the flexibility to operate at a different
voltage than the other serial interfaces.
The I2C controller supports bus frequencies of 100 kHz,
400 kHz, and 1 MHz. When VIO5 is 1.2 V, 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. The I2C controller supports the clock-stretching
feature to enable slower devices to exercise flow control.
The I2C interface’s SCL and SDA signals require external pull-up
resistors. The pull-up resistors must be connected to VIO5.
I2S Interface
FX3S has an I2S port to support external audio codec devices.
FX3S 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). FX3S can generate the system clock
as an output on I2S_MCLK or accept an external system clock
input on I2S_MCLK.
The sampling frequencies supported by the I2S interface are
8 kHz, 16 kHz, 32 kHz, 44.1 kHz, 96 kHz and 192 kHz.
SPI Interface
FX3S supports an SPI Master interface on the Serial Peripherals
port. The maximum operation frequency is 33 MHz.
The SPI controller supports four modes of SPI communication
(see SPI Timing Specification on page 47 for details on the
modes) with the Start-Stop clock. This controller is a
single-master controller with a single automated SSN control. It
supports transaction sizes ranging from 4 bits to 32 bits.

specific reset sequence and timing requirements are detailed in
Figure 31 on page 49 and Table 27 on page 49. All I/Os are
tristated during a hard reset.
Soft Reset
In a soft reset, the processor sets the appropriate bits in the
PP_INIT control register. There are two types of Soft Reset:

Clocking
Clock inputs to FX3S must meet the phase noise and jitter
requirements specified in Table 4.
FX3S allows either a crystal to be connected between the
XTALIN and XTALOUT pins or an external clock to be connected
at the CLKIN pin. The XTALIN, XTALOUT, CLKIN, and
CLKIN_32 pins can be left unconnected if they are not used.
The input clock frequency is independent of the clock and data
rate of the FX3S 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.
Crystal frequency supported is 19.2 MHz, while the external
clock frequencies supported are 19.2, 26, 38.4, and 52 MHz.
Table 3. Crystal/Clock Frequency Selection
FX3S has an on-chip oscillator circuit that uses an external
19.2-MHz (±100 ppm) crystal (when the crystal option is used).
An appropriate load capacitance is required with a crystal. Refer
to the specification of the crystal used to determine the
appropriate load capacitance. The FSLC[2:0] pins must be
configured appropriately to select the crystal- or clock-frequency
option. The configuration options are shown in Table 3.

32-kHz Watchdog Timer Clock Input
FX3S includes a watchdog timer. The watchdog timer can be
used to interrupt the ARM926EJ-S core, automatically wake up
the FX3S in Standby mode, and reset the ARM926EJ-S core.
The watchdog timer runs a 32-kHz clock, which may be
optionally supplied from an external source on a dedicated FX3S
pin.
The firmware can disable the watchdog timer.

Power
transceiver through FX3S’s internal voltage regulator. VBATT
is internally regulated to 3.3 V.
FX3S has the following power supply domains:
■
■
IO_VDDQ: This is a group of independent supply domains for
digital I/Os. The voltage level on these supplies is 1.8 V to 3.3 V.
FX3S provides six independent supply domains for digital I/Os
listed as follows (see Pin Description on page 17 for details on
each of the power domain signals):
❐ VIO1: GPIF II I/O
❐ VIO2: S0-Port Supply
❐ VIO3: S1-Port Supply
❐ VIO4: S1-Port and Low Speed Peripherals (UART/SPI/I2S)
Supply
2
❐ VIO5: I C and JTAG (supports 1.2 V to 3.3 V)
❐ CVDDQ: Clock
❐ VDD: This is the supply voltage for the logic core. The nominal
supply-voltage level is 1.2 V. This supplies the core logic
circuits. The same supply must also be used for the following:
• AVDD: This is the 1.2-V supply for the PLL, crystal
oscillator, and other core analog circuits
• U3TXVDDQ/U3RXVDDQ: These are the 1.2-V supply
voltages for the USB 3.0 interface.
VBATT/VBUS: This is the 3.2-V to 6-V battery power supply for
the USB I/O and analog circuits. This supply powers the USB
Note: No specific power-up sequence for FX3S power domains.
Minimum power on reset time of 1 ms should be met and the
power domains must be stable for FX3S operation.
Power Modes
FX3S supports the following power modes:
■
Normal mode: This is the full-functional operating mode. The
internal CPU clock and the internal PLLs are enabled in this
mode.
❐ Normal operating power consumption does not exceed the
sum of ICC Core max and ICC USB max (see the DC
Specifications table for current consumption specifications).
❐ The I/O power supplies VIO2, VIO3, VIO4, and VIO5 can be
turned off when the corresponding interface is not in use.
VIO1 cannot be turned off at any time if the GPIF II interface
is used in the application.
■
Low-power modes (see Table 6):
❐ Suspend mode with USB 3.0 PHY enabled (L1)
❐ Suspend mode with USB 3.0 PHY disabled (L2)
❐ Standby mode (L3)

Configuration Options
Configuration options are available for specific usage models.
Contact Cypress Applications or Marketing for details.
Digital I/Os
FX3S has internal firmware-controlled pull-up or pull-down
resistors on all digital I/O pins. An internal 50-k resistor pulls
the pins high, while an internal 10-k resistor pulls the pins low
to prevent them 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 TDI, TMC, and TRST# signals have fixed 50-k
internal pull-ups, and the TCK signal has a fixed 10-k
pull-down resistor.
All unused I/Os should be pulled high by using the internal
pull-up resistors. All unused outputs should be left floating. All
I/Os can be driven at full-strength, three-quarter strength,
half-strength, or quarter-strength. These drive strengths are
configured separately for each interface.
GPIOs
EZ-USB enables a flexible pin configuration both on the GPIF II
and the serial peripheral interfaces. Any unused control pins
(except CTL[15]) on the GPIF II interface can be used as GPIOs.
Document Number: 001-84160 Rev. *J
Similarly, any unused pins on the serial peripheral interfaces may
be configured as GPIOs. See the Pin Description on page 17 for
pin configuration options.
All GPIF II and GPIO pins support an external load of up to 16 pF
for every pin.
EMI
FX3S meets EMI requirements outlined by FCC 15B (USA) and
EN55022 (Europe) for consumer electronics. FX3S can tolerate
reasonable EMI, conducted by the aggressor, outlined by these
specifications and continue to function as expected.
System-level ESD
FX3S has built-in ESD protection on the D+, D–, and GND pins
on the USB interface. The ESD protection levels provided on
these ports are:
■
±2.2-KV human body model (HBM) based on JESD22-A114
Specification
■
±6-KV contact discharge and ±8-KV air gap discharge based
on IEC61000-4-2 level 3A
■
± 8-KV Contact Discharge and ±15-KV Air Gap Discharge
based on IEC61000-4-2 level 4C.
This protection ensures the device continues to function after
ESD events up to the levels stated in this section.
The SSRX+, SSRX–, SSTX+, and SSTX– pins only have up to
±2.2-KV HBM internal ESD protection.

3. Slave FIFO is an example configuration of GPIF II Interface. The Slave FIFO control signal assignments can be modified using GPIF-II designer tool.
4. For 8-bit data bus configuration, GPIO[8] and GPIO[9] act as address lines.
5. GPIF II can also be configured as a serial interface. The DQ[15] pin becomes a serial output and DQ[14] becomes a serial input in this mode.

Slave FIFO Interface
Socket Switching Delay (Tssd):
Synchronous Slave FIFO Sequence Description
■
FIFO address is stable and SLCS is asserted
■
FLAG indicates FIFO not empty status
■
SLOE is asserted. SLOE is an output-enable only, whose sole
function is to drive the data bus.
■
SLRD is asserted
The FIFO pointer is updated on the rising edge of the PCLK,
while the SLRD is asserted. This starts the propagation of data
from the newly addressed location to the data bus. 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.
The same sequence of events is shown for a burst read.
FLAG Usage:
The socket-switching delay is measured from the time
EPSWITCH# is asserted by the master, with the new socket
address on the address bus, to the time the Current_Thread_DMA_Ready flag is asserted. For the Producer socket, the flag is
asserted when it is ready to receive data in the DMA buffer. For
the Consumer socket, the flag is asserted when it is ready to
drive data out of the DMA buffer. For a synchronous slave FIFO
interface, the switching delay is measured in the number of GPIF
interface clock cycles; for an asynchronous slave FIFO interface,
in PIB clock cycles. This is applicable only for the 5-bit Slave
FIFO interface; there is no socket-switching delay in FX3’s 2-bit
Slave FIFO interface, which makes use of thread switching in the
GPIF™ II state machine.
Note For burst mode, the SLRD# and SLOE# are asserted
during the entire duration of the read. When SLOE# is asserted,
the data bus is driven (with data from the previously addressed
FIFO). For each subsequent rising edge of PCLK, while the
SLRD# is asserted, the FIFO pointer is incremented and the next
data value is placed on the data bus.
The FLAG signals are monitored for flow control by the external
processor. FLAG signals are outputs from FX3S that may be
configured to show empty, full, or partial status for a dedicated
thread or the current thread that is addressed.

Short Packet: A short packet can be committed to the USB host
by using the PKTEND#. The external device or processor should
be designed to assert the PKTEND# along with the last word of
data and SLWR# pulse corresponding to the last word. The
FIFOADDR lines must be held constant during the PKTEND#
assertion.
Synchronous Slave FIFO Write Sequence Description
■
FIFO address is stable and the signal SLCS# is asserted
■
External master or peripheral outputs the data to the data bus
■
SLWR# is asserted
■
While the SLWR# is asserted, data is written to the FIFO and
on the rising edge of the PCLK, the FIFO pointer is incremented
■
The FIFO flag is updated after a delay of t WFLG from the rising
edge of the clock
Zero-Length Packet: The external device or processor can
signal a Zero-Length Packet (ZLP) to FX3S simply by asserting
PKTEND#, without asserting SLWR#. SLCS# and address must
be driven as shown in Figure 25.
The same sequence of events is also shown for burst write
Note For the burst mode, SLWR# and SLCS# are asserted for
the entire duration, during which all the required data values are
written. In this burst write mode, after the SLWR# is asserted, the
data on the FIFO data bus is written to the FIFO on every rising
edge of PCLK. The FIFO pointer is updated on each rising edge
of PCLK.

Asynchronous Slave FIFO Read Sequence
Description
■
FIFO address is stable and the SLCS# signal is asserted.
In Figure 26 on page 38, data N is the first valid data read from
the FIFO. For data to appear on the data bus during the read
cycle, SLOE# must be in an asserted state. SLRD# and SLOE#
can also be tied.
■
SLOE# is asserted. This results in driving the data bus.
The same sequence of events is also shown for a burst read.
■
SLRD # is asserted.
■
Data from the FIFO is driven after assertion of SLRD#. This
data is valid after a propagation delay of tRDO from the falling
edge of SLRD#.
Note In the burst read mode, during SLOE# assertion, the data
bus is in a driven state (data is driven from a previously
addressed FIFO). After assertion of SLRD# data from the FIFO
is driven on the data bus (SLOE# must also be asserted). The
FIFO pointer is incremented after deassertion of SLRD#.
■
FIFO pointer is incremented on deassertion of SLRD#

Asynchronous Slave FIFO Write Sequence
Description
■
FIFO address is driven and SLCS# is asserted
■
SLWR# is asserted. SLCS# must be asserted with SLWR# or
before SLWR# is asserted
■
Data must be present on the tWRS bus before the deasserting
edge of SLWR#
■
Deassertion of SLWR# causes the data to be written from the
data bus to the FIFO, and then the FIFO pointer is incremented
■
The FIFO flag is updated after the tWFLG from the deasserting
edge of SLWR.
The same sequence of events is shown for a burst write.
Short Packet: A short packet can be committed to the USB host
by using the PKTEND#. The external device or processor should
be designed to assert the PKTEND# along with the last word of
data and SLWR# pulse corresponding to the last word. The
FIFOADDR lines must be held constant during the PKTEND#
assertion.
Zero-Length Packet: The external device or processor can
signal a zero-length packet (ZLP) to FX3S simply by asserting
PKTEND#, without asserting SLWR#. SLCS# and the address
must be driven as shown in Figure 27 on page 39.
FLAG Usage: The FLAG signals are monitored by the external
processor for flow control. FLAG signals are FX3S outputs that
can be configured to show empty, full, and partial status for a
dedicated address or the current address.
Note that in the burst write mode, after SLWR# deassertion, the
data is written to the FIFO, and then the FIFO pointer is
incremented.

1. Turning off VIO1 during Normal, Suspend, and Standby modes causes the FX3S to stop working.
■Problem
Definition
Turning off the VIO1 during Normal, Suspend, and Standby modes will cause the FX3S to stop working.
■Parameters
N/A
Affected
■Trigger
Conditions
This condition is triggered when the VIO1 is turned off during Normal, Suspend, and Standby modes.
■Scope
Of Impact
FX3S stops working.
■Workaround
VIO1 must stay on during Normal, Suspend, and Standby modes.
■Fix
Status
No fix. Workaround is required.
2. USB enumeration failure in USB boot mode when FX3S is self-powered.
■Problem
Definition
When FX3S is self-powered and not connected to the USB host, it enters low-power mode and does not wake up when connected
to USB host afterwards. This is because the bootloader does not check the VBUS pin on the connector to detect USB connection.
It expects that the USB bus is connected to the host when it is powered on.
■Parameters
N/A
Affected
■Trigger
Conditions
This condition is triggered when FX3S is self-powered in USB boot mode.
■Scope
Of Impact
Device does not enumerate
■Workaround
Reset the device after connecting to USB host.
■Fix
Status
No fix. Workaround is required.
3. Extra ZLP is generated by the COMMIT action in the GPIF II state.
■Problem
Definition
When COMMIT action is used in a GPIF-II state without IN_DATA action then an extra Zero Length Packet (ZLP) is committed
along with the data packets.
■Parameters
N/A
Affected
■Trigger
Conditions
This condition is triggered when COMMIT action is used in a state without IN_DATA action.
■Scope
Of Impact
Extra ZLP is generated.
■Workaround
Use IN_DATA action along with COMMIT action in the same state.
■Fix
Status
No fix. Workaround is required.

4. Invalid PID Sequence in USB 2.0 ISOC data transfer.
■Problem
Definition
When the FX3S device is functioning as a high speed USB device with high bandwidth isochronous endpoints, the PID sequence
of the ISO data packets is governed solely by the isomult setting. The length of the data packet is not considered while generating
the PID sequence during each microframe. For example, even if a short packet is being sent on an endpoint with MULT set to 2;
the PID used will be DATA2
■Parameters
N/A
Affected
■Trigger
Conditions
This condition is triggered when high bandwidth ISOC transfer endpoints are used.
■Scope
Of Impact
ISOC data transfers failure.
■Workaround
This problem can be worked around by reconfiguring the endpoint with a lower isomult setting prior to sending short packets, and
then switching back to the original value.
■Fix
Status
No fix. Workaround is required.
5. USB data transfer errors are seen when ZLP is followed by data packet within same microframe.
■Problem
Definition
Some data transfer errors may be seen if a Zero Length Packet is followed very quickly (within one microframe or 125 µs) by
another data packet on a burst enabled USB IN endpoint operating at super speed.
■Parameters
N/A
Affected
■Trigger
Conditions
This condition is triggered in SuperSpeed transfer with ZLPs
■Scope
Of Impact
Data failure and lower data speed.
■Workaround
The solution is to ensure that some time is allowed to elapse between a ZLP and the next data packet on burst enabled USB IN
endpoints. If this cannot be ensured at the data source, the CyU3PDmaChannelSetSuspend() API can be used to suspend the
corresponding USB DMA socket on seeing the EOP condition. The channel operation can then be resumed as soon as the
suspend callback is received.
■Fix
Status
No fix. Workaround is required.
6. Bus collision is seen when the I2C block is used as a master in the I2C Multi-master configuration.
■Problem
Definition
When FX3S is used as a master in the I2C multi-master configuration, there can be occasional bus collisions.
■Parameters
NA
Affected
■Trigger
Conditions
This condition is triggered only when the FX3S I2C block operates in Multi-master configuration.
■Scope
Of Impact
The FX3S I2C block can transmit data when the I2C bus is not idle leading to bus collision.
■Workaround
Use FX3S as a single master.
■Fix
Status
No fix.

7. Low Power U1 Fast-Exit Issue with USB3.0 host controller.
■Problem
Definition
When FX3S device transitions from Low power U1 state to U0 state within 5 µs after entering U1 state, the device sometimes
fails to transition back to U0 state, resulting in USB Reset.
■Parameters
N/A
Affected
■Trigger
Conditions
This condition is triggered during low power transition mode.
■Scope
Of Impact
Unexpected USB warm reset during data transfer.
■Workaround
This problem can be worked around in the FW by disabling LPM (Link Power Management) during data transfer.
■Fix
Status
FW workaround is proven and reliable.
8. USB data corruption when operating on hosts with poor link quality.
■Problem
Definition
If FX3S is operating on a USB 3.0 link with poor signal quality, the device could send corrupted data on any of the IN endpoints
(including the control endpoint).
■Parameters
N/A
Affected
■Trigger
Conditions
This condition is triggered when the USB3.0 link signal quality is very poor.
■Scope
Of Impact
Data corruption in any of the IN endpoints (including the control endpoint).
■Workaround
The application firmware should perform an error recovery by stalling the endpoint on receiving CYU3P_USBEPSS_RESET_EVT
event, and then stop and restart DMA path when the CLEAR_FEATURE request is received.
Note: SDK versions 1.3.3 and above internally manages the DMA transfers and performs the endpoint reset when potential error
conditions are seen. For more details in application firmware, please refer to GpiftoUsb example available with SDK.
■Fix
Status
FW workaround is proven and reliable.

9. Device treats Rx Detect sequence from the USB 3.0 host as a valid U1 exit LFPS burst.
■Problem
Definition
The USB 3.0 PHY in the FX3S device uses an electrical idle detector to determine whether LFPS is being received. The duration
for which the receiver does not see an electrical idle condition is timed to detect various LFPS bursts. This implementation causes
the device to treat an Rx Detect sequence from the USB host as a valid U1 exit LFPS burst.
■Parameters
NA
Affected
■Trigger
Conditions
This condition is triggered when the USB host is initiating an Rx Detect sequence while the USB 3.0 Link State Machine on the
FX3S is in the U1 state. Since the host will only perform Rx Detect sequence in the RX Detect and U2 states, the error condition
is seen only in cases where the USB link on the host has moved into the U2 state while the link on FX3S is in the U1 state.
■Scope
Of Impact
FX3S moves into Recovery prematurely leading to a Recovery failure followed by Warm Reset and USB re-enumeration. This
sequence can repeat multiple times resulting in data transfer failures.
■Workaround
FX3S can be configured to transition from U1 to U2 a few microseconds before the host does so. This will ensure that the link
will be in U2 on the device side before the host attempts any Rx Detect sequence; thereby preventing a false detection of U1 exit.
■Fix
Status
Workaround is implemented in FX3S SDK library 1.3.4 and above.
10. I2C Data Valid (tVD:DAT) specification violation at 400 kHz with a 40/60 duty cycle.
■Problem
2
Definition
I C Data Valid (tVD:DAT) parameter at 400 kHz with a 40/60 duty cycle is 1.0625 µs, which exceeds the I2C specification limit of
0.9 µs.
■Parameters
N/A
Affected
■Trigger
Conditions
This violation occurs only at 400 kHz with a 40/60 duty cycle of the I2C clock.
■Scope
Of Impact
Setup time (tSUDAT) is met with a huge margin for the transmitted data for 400 kHz and so tvd:DAT violation will not cause any data
integrity issues.
■Workaround
No workaround needed.
■Fix
Status
No fix needed.

11. FX3S Device does not respond correctly to Port Capability Request from Host after multiple power cycles.
■Problem
Definition
During multiple power cycles, sometimes the FX3S device does not respond correctly to the Port Capability request (Link Packet)
from the USB Controller. In view of this, FX3S does not get the subsequent Port Configuration request from the USB controller,
resulting in SS.Disabled state. The device fails to recover from this state and finally results in enumeration failure.
■Parameters
N/A
Affected
■Trigger
Conditions
This condition is triggered when the FX3S provides an incorrect response to the Port Capability request from the host.
■Scope
Of Impact
Device fails to enumerate after multiple retries.
■Workaround
Since the host does not send the Port Configuration request to the FX3S device, it causes a Port Configuration request timeout
interrupt to be triggered in the device. This interrupt is handled in the FX3 SDK 1.3.4 onwards to generate and signal CY_U3P_USB_EVENT_LMP_EXCH_FAIL event to the application. This event should be handled in the user application such that it does a
USB Interface Block Restart. Refer the Knowledge Base Article (KBA225778) for more details and the firmware workaround
example project.
■Fix
Status
Suggested firmware work-around is proven and reliable.
