Cypress’s EZ-USB® FX2LP (CY7C68013A/14A) is a
low-power version of the EZ-USB FX2(CY7C68013), which is
a highly integrated, low-power USB 2.0 microcontroller. By
integrating the USB 2.0 transceiver, serial interface engine (SIE),
enhanced 8051 microcontroller, and a programmable peripheral
interface in a single chip, Cypress has created a cost-effective
solution that provides superior time-to-market advantages with
low power to enable bus-powered applications.
With EZ-USB FX2LP, the Cypress Smart SIE handles most of
the USB 1.1 and 2.0 protocol in hardware, freeing the embedded
microcontroller for application-specific functions and decreasing
the development time to ensure USB compatibility.
The ingenious architecture of FX2LP results in data transfer
rates of over 53 Mbytes per second (the maximum allowable
USB 2.0 bandwidth), while still using a low-cost 8051
microcontroller in a package as small as a 56 VFBGA (5 mm x
5 mm). Because it incorporates the USB 2.0 transceiver, the
FX2LP is more economical, providing a smaller-footprint solution
than a USB 2.0 SIE or external transceiver implementations.
The FX2LP draws less current than the FX2 (CY7C68013), has
double the on-chip code/data RAM, and is fit, form, and function
compatible with the 56-, 100-, and 128-pin FX2.
Document Number: 38-08032 Rev. *X
The general programmable interface (GPIF) and Master/Slave
Endpoint FIFO (8-bit or 16-bit data bus) provide an easy and
glueless interface to popular interfaces such as ATA, UTOPIA,
EPP, PCMCIA, and most DSP/processors.
Five packages are defined for the family: 56 VFBGA, 56 SSOP,
56 QFN, 100 TQFP, and 128 TQFP.

FX2LP contains two standard 8051 USARTs, addressed through
Special Function Register (SFR) bits. The USART interface pins
are available on separate I/O pins, and are not multiplexed with
port pins.
FX2LP operates at two of the three rates defined in the USB
Specification Revision 2.0, dated April 27, 2000:
UART0 and UART1 can operate using an internal clock at
230 KBaud with no more than 1% baud rate error. 230 KBaud
operation is achieved by an internally derived clock source that
generates overflow pulses at the appropriate time. The internal
clock adjusts for the 8051 clock rate (48 MHz, 24 MHz, and
12 MHz) such that it always presents the correct frequency for
the 230-KBaud operation.[1]

■

Certain 8051 SFR addresses are populated to provide fast
access to critical FX2LP functions. These SFR additions are
shown in Table 1 on page 6. Bold type indicates nonstandard,
enhanced 8051 registers. The two SFR rows that end with “0”
and “8” contain bit-addressable registers. The four I/O ports A to
D use the SFR addresses used in the standard 8051 for ports 0
to 3, which are not implemented in FX2LP. Because of the faster
and more efficient SFR addressing, the FX2LP I/O ports are not
addressable in external RAM space (using the MOVX
instruction).
2. Functional Overview
2.1 USB Signaling Speed
FX2LP does not support the Low Speed signaling mode of
1.5 Mbps.
2.2 8051 Microprocessor
The 8051 microprocessor embedded in the FX2LP family has
256 bytes of register RAM, an expanded interrupt system, three
timer/counters, and two USARTs.
2.2.1 8051 Clock Frequency
FX2LP has an on-chip oscillator circuit that uses an external
24-MHz (±100 ppm) crystal with the following characteristics:
2.3 I2C Bus
■
Parallel resonant
■
Fundamental mode
FX2LP supports the I2C bus as a master only at 100/400 kHz.
SCL and SDA pins have open-drain outputs and hysteresis
inputs. These signals must be pulled up to 3.3 V, even if no I2C
device is connected.
■
500-W drive level
2.4 Buses
■
12-pF (5% tolerance) load capacitors
All packages, 8-bit or 16-bit “FIFO” bidirectional data bus,
multiplexed on I/O ports B and D. 128-pin package: adds 16-bit
output-only 8051 address bus, 8-bit bidirectional data bus.
An on-chip PLL multiplies the 24-MHz oscillator up to 480 MHz,
as required by the transceiver/PHY; internal counters divide it
down for use as the 8051 clock. The default 8051 clock
frequency is 12 MHz. The clock frequency of the 8051 can be
changed by the 8051 through the CPUCS register, dynamically.
Note
1. 115-KBaud operation is also possible by programming the 8051 SMOD0 or SMOD1 bits to a “1” for UART0, UART1, or both respectively.

2.5 USB Boot Methods
During the power-up sequence, internal logic checks the I2C port
for the connection of an EEPROM whose first byte is either 0xC0
or 0xC2. If found, it uses the VID/PID/DID values in the EEPROM
in place of the internally stored values (0xC0), or it boot-loads the
EEPROM contents into internal RAM (0xC2). If no EEPROM is
detected, FX2LP enumerates using internally stored descriptors.
The default ID values for FX2LP are VID/PID/DID (0x04B4,
0x8613, 0xAxxx where xxx = Chip revision).[2]
Table 2. Default ID Values for FX2LP
Vendor ID

Device release
Default VID/PID/DID
0x04B4 Cypress Semiconductor
0x8613 EZ-USB FX2LP
0xAnnn Depends on chip revision
(nnn = chip revision where first
silicon = 001)
2.6 ReNumeration
Because the FX2LP’s configuration is soft, one chip can take on
the identities of multiple distinct USB devices.
When first plugged into USB, the FX2LP enumerates
automatically and downloads firmware and USB descriptor
tables over the USB cable. Next, the FX2LP 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, without a hint that the
initial download step has occurred.
GPIFSGLDATH
GPIFSGLDATLX
GPIFSGLDATLNOX
Two control bits in the USBCS (USB Control and Status) register
control the ReNumeration process: DISCON and RENUM. To
simulate a USB disconnect, the firmware sets DISCON to 1. To
reconnect, the firmware clears DISCON to 0.
Before reconnecting, the firmware sets or clears the RENUM bit
to indicate whether the firmware or the Default USB Device
handles device requests over endpoint zero: if RENUM = 0, the
Default USB Device handles device requests; if RENUM = 1, the
firmware services the requests.
2.7 Bus-Powered Applications
The FX2LP fully supports bus-powered designs by enumerating
with less than 100 mA as required by the USB 2.0 specification.
2.8 Interrupt System
2.8.1 INT2 Interrupt Request and Enable Registers
FX2LP implements an autovector feature for INT2 and INT4.
There are 27 INT2 (USB) vectors, and 14 INT4 (FIFO/GPIF)
vectors. See EZ-USB Technical Reference Manual (TRM) for
more details.
2.8.2 USB Interrupt Autovectors
The main USB interrupt is shared by 27 interrupt sources. To
save the code and processing time that is required to identify the
individual USB interrupt source, the FX2LP provides a second
level of interrupt vectoring, called Autovectoring. When a USB
interrupt is asserted, the FX2LP pushes the program counter to
its stack, and then jumps to the address 0x0043 where it expects
to find a “jump” instruction to the USB interrupt service routine.
Note
2. The I2C bus SCL and SDA pins must be pulled up, even if an EEPROM is not connected. Otherwise this detection method does not work properly.

If Autovectoring is enabled (AV2EN = 1 in the INTSET-UP register), the FX2LP substitutes its INT2VEC byte. Therefore, if the high
byte (“page”) of a jump table address is preloaded at the location 0x0044, the automatically inserted INT2VEC byte at 0x0045 directs
the jump to the correct address out of the 27 addresses within the page.
2.8.3 FIFO/GPIF Interrupt (INT4)
Just as the USB Interrupt is shared among 27 individual USB interrupt sources, the FIFO/GPIF interrupt is shared among 14 individual
FIFO/GPIF sources. The FIFO/GPIF Interrupt, similar to the USB Interrupt, can employ autovectoring. Table 4 on page 8 shows the
priority and INT4VEC values for the 14 FIFO/GPIF interrupt sources.

If Autovectoring is enabled (AV4EN = 1 in the INTSET-UP
register), the FX 2LP substitutes its INT4VEC byte. Therefore, if
the high byte (“page”) of a jump-table address is preloaded at
location 0x0054, the automatically inserted INT4VEC byte at
0x0055 directs the jump to the correct address out of the 14
addresses within the page. When the ISR occurs, the FX2LP
pushes the program counter to its stack then jumps to address
0x0053, where it expects to find a “jump” instruction to the ISR
Interrupt service routine.
Note
3. Errata: In Slave FIFO Asynchronous Word Wide mode, if a single word data is transferred from the USB host to EP2, configured as OUT Endpoint (EP) in the first
transaction, then the Empty flag behaves incorrectly. This does not happen if the data size is more than one word in the first transaction. For more information, see
the “Errata” on page 67.

2.9 Reset and Wakeup
2.9.1 Reset Pin
The input pin, RESET#, resets the FX2LP when asserted. This
pin has hysteresis and is active LOW. When a crystal is used with
the CY7C680xxA, the reset period must enable stabilization of
the crystal and the PLL. This reset period must be approximately
5 ms after VCC reaches 3.0 V. If the crystal input pin is driven by
a clock signal, the internal PLL stabilizes in 200 s after VCC has
reached 3.0 V.[4]
Figure 2-2 on page 9 shows a power-on reset condition and a
reset applied during operation. A power-on reset is defined as
the time reset that is asserted while power is being applied to the
circuit. A powered reset is when the FX2LP is powered on and
operating and the RESET# pin is asserted.
Cypress provides an application note which describes and
recommends power-on reset implementation. For more
information about reset implementation for the FX2 family of
products, visit http://www.cypress.com.

External logic asserts the PA3/WU2 pin
The 8051 puts itself and the rest of the chip into a power-down
mode by setting PCON.0 = 1. This stops the oscillator and PLL.
When WAKEUP is asserted by external logic, the oscillator
restarts after the PLL stabilizes, and the 8051 receives a wakeup
The second wakeup pin, WU2, can also be configured as a
general-purpose I/O pin. This enables a simple external R-C
network to be used as a periodic wakeup source. WAKEUP is by
default active LOW.
Note
4. If the external clock is powered at the same time as the CY7C680xxA and has a stabilization wait period, it must be added to the 200 s.

enables the user to connect a 64 KB memory without requiring
address decodes to keep clear of internal memory spaces.
2.10.1 SizeThe FX2LP has 16 KB of internal program/data RAM,
where PSEN#/RD# signals are internally ORed to enable
the 8051 to access it as both program and data memory.
No USB control registers appears in this space.
Only the internal 16 KB and scratch pad 0.5 KB RAM spaces
have the following access:
Two memory maps are shown in the following diagrams:

2.13 External FIFO Interface
2.13.1 Architecture
The FX2LP slave FIFO architecture has eight 512-byte blocks in
the endpoint RAM that directly serve as FIFO memories and are
controlled by FIFO control signals (such as IFCLK, SLCS#,
SLRD, SLWR, SLOE, PKTEND, and flags).
In operation, some of the eight RAM blocks fill or empty from the
SIE, while the others are connected to the I/O transfer logic. The
transfer logic takes two forms: the GPIF for internally generated
control signals and the slave FIFO interface for externally
controlled transfers.
2.13.2 Master/Slave Control Signals
The FX2LP endpoint FIFOs are implemented as eight physically
distinct 25616 RAM blocks. The 8051/SIE can switch any of the
RAM blocks between two domains, the USB (SIE) domain and
the 8051-I/O Unit domain. This switching is done virtually
instantaneously, giving essentially zero transfer time between
“USB FIFOs” and “Slave FIFOs.” Because they are physically
the same memory, no bytes are actually transferred between
buffers.
At any time, some RAM blocks are filling/emptying with the USB
data under SIE control, while other RAM blocks are available to
the 8051, the I/O control unit, or both. The RAM blocks operates
as single-port in the USB domain, and dual-port in the 8051-I/O
domain. The blocks can be configured as single-, double-, triple-,
or quad-buffered as previously shown.
The I/O control unit implements either an internal master (M for
Master) or external master (S for Slave) interface.
In Master (M) mode, the GPIF internally controls FIFOADR[1..0]
to select a FIFO. The RDY pins (two in the 56-pin package, six
in the 100-pin and 128-pin packages) can be used as flag inputs
from an external FIFO or other logic if desired. The GPIF can be
run from either an internally derived clock or externally supplied
clock (IFCLK), at a rate that transfers data up to 96 MBytes/s (48
MHz IFCLK with 16-bit interface).
In the Slave (S) mode, FX2LP accepts either an internally
derived clock or externally supplied clock (IFCLK, max frequency
48 MHz) and SLCS#, SLRD, SLWR, SLOE, PKTEND signals
from external logic. When using an external IFCLK, the external
clock must be present before switching to the external clock with
the IFCLKSRC bit. Each endpoint can individually be selected
for byte or word operation by an internal configuration bit and a
Slave FIFO Output Enable signal (SLOE)that enables data of the
selected width. External logic must ensure that the output enable
signal is inactive when writing data to a slave FIFO. The slave
interface can also operate asynchronously, where the SLRD and
SLWR signals act directly as strobes, rather than a clock qualifier
as in synchronous mode. The signals SLRD, SLWR, SLOE, and
PKTEND are gated by the signal SLCS#.
Notes
5. “0” means “not implemented.”
6. “2×” means “double buffered.”
7. Even though these buffers are 64 bytes, they are reported as 512 for USB 2.0 compliance. The user must never transfer packets larger than 64 bytes to EP1.

CY7C68015A, CY7C68016A
2.13.3 GPIF and FIFO Clock Rates
2.15 ECC Generation[8]
An 8051 register bit selects one of two frequencies for the
internally supplied interface clock: 30 MHz and 48 MHz.
Alternatively, an externally supplied clock of 5 MHz–48 MHz
feeding the IFCLK pin can be used as the interface clock. IFCLK
can be configured to function as an output clock when the GPIF
and FIFOs are internally clocked. An output enable bit in the
IFCONFIG register turns this clock output off, if desired. Another
bit within the IFCONFIG register inverts the IFCLK signal
whether internally or externally sourced.
The EZ-USB can calculate ECCs (Error Correcting Codes) on
data that passes across its GPIF or Slave FIFO interfaces. There
are two ECC configurations: Two ECCs, each calculated over
256 bytes (SmartMedia Standard); and one ECC calculated over
512 bytes.
2.14 GPIF
ECCM = 0
The GPIF is a flexible 8-bit or 16-bit parallel interface driven by
a user-programmable finite state machine. It enables the
CY7C68013A/15A to perform local bus mastering and can
implement a wide variety of protocols such as ATA interface,
printer parallel port, and Utopia.
Two 3-byte ECCs, each calculated over a 256-byte block of data.
This configuration conforms to the SmartMedia Standard.
The GPIF has six programmable control outputs (CTL), nine
address outputs (GPIFADRx), and six general-purpose ready
inputs (RDY). The data bus width can be 8 or 16 bits. Each GPIF
vector defines the state of the control outputs, and determines
what state a ready input (or multiple inputs) must be before
proceeding. The GPIF vector can be programmed to advance a
FIFO to the next data value, advance an address, etc. A
sequence of the GPIF vectors make up a single waveform that
is executed to perform the desired data move between the
FX2LP and the external device.
2.14.1 Six Control OUT Signals
The 100-pin and 128-pin packages bring out all six Control
Output pins (CTL0-CTL5). The 8051 programs the GPIF unit to
define the CTL waveforms. The 56-pin package brings out three
of these signals, CTL0–CTL2. CTLx waveform edges can be
programmed to make transitions as fast as once per clock
(20.8 ns using a 48-MHz clock).
2.14.2 Six Ready IN Signals
The 100-pin and 128-pin packages bring out all six Ready inputs
(RDY0–RDY5). The 8051 programs the GPIF unit to test the
RDY pins for GPIF branching. The 56-pin package brings out two
of these signals, RDY0–1.
2.14.3 Nine GPIF Address OUT Signals
Nine GPIF address lines are available in the 100-pin and 128-pin
packages, GPIFADR[8..0]. The GPIF address lines enable
indexing through up to a 512-byte block of RAM. If more address
lines are needed, then I/O port pins are used.
2.14.4 Long Transfer Mode
In the master mode, the 8051 appropriately sets GPIF
transaction count registers (GPIFTCB3, GPIFTCB2, GPIFTCB1,
or GPIFTCB0) for unattended transfers of up to 232 transactions.
The GPIF automatically throttles data flow to prevent under or
overflow until the full number of requested transactions
complete. The GPIF decrements the value in these registers to
represent the current status of the transaction.
The ECC can correct any one-bit error or detect any two-bit error.
2.15.1 ECC Implementation
The two ECC configurations are selected by the ECCM bit:
Write any value to ECCRESET, then pass data across the GPIF
or Slave FIFO interface. The ECC for the first 256 bytes of data
is calculated and stored in ECC1. The ECC for the next 256 bytes
is stored in ECC2. After the second ECC is calculated, the values
in the ECCx registers do not change until ECCRESET is written
again, even if more data is subsequently passed across the
interface.
ECCM = 1
One 3-byte ECC calculated over a 512-byte block of data.
Write any value to ECCRESET then pass data across the GPIF
or Slave FIFO interface. The ECC for the first 512 bytes of data
is calculated and stored in ECC1; ECC2 is unused. After the
ECC is calculated, the values in ECC1 do not change even if
more data is subsequently passed across the interface, till
ECCRESET is written again.
2.16 USB Uploads and Downloads
The core has the ability to directly edit the data contents of the
internal 16-KB RAM and of the internal 512-byte scratch pad
RAM via a vendor-specific command. This capability is normally
used when soft downloading the user code and is available only
to and from the internal RAM, only when the 8051 is held in reset.
The available RAM spaces are 16 KB from 0x0000–0x3FFF
(code/data) and 512 bytes from 0xE000–0xE1FF (scratch pad
data RAM).[9]
2.17 Autopointer Access
FX2LP provides two identical autopointers. They are similar to
the internal 8051 data pointers but with an additional feature:
they can optionally increment after every memory access. This
capability is available to and from both internal and external
RAM. Autopointers are available in external FX2LP registers
under the control of a mode bit (AUTOPTRSET-UP.0). Using the
external FX2LP autopointer access (at 0xE67B – 0xE67C)
enables the autopointer to access all internal and external RAM
to the part.
Also, autopointers can point to any FX2LP register or endpoint
buffer space. When the autopointer access to external memory
is enabled, locations 0xE67B and 0xE67C in XDATA and code
space cannot be used.
Notes
8. To use the ECC logic, the GPIF or Slave FIFO interface must be configured for byte-wide operation.
9. After the data is downloaded from the host, a “loader” can execute from internal RAM to transfer downloaded data to external memory.

2.18 I2C Controller
2
FX2LP has one I C port that is driven by two internal controllers,
the one that automatically operates at boot time to load
VID/PID/DID and configuration information, and another that the
8051 uses when running to control external I2C devices. The I2C
port operates in master mode only.
Table 8. Part Number Conversion Table
2.18.1 I2C Port Pins
The I2C pins SCL and SDA must have external 2.2-k pull-up
resistors even if no EEPROM is connected to the FX2LP.
External EEPROM device address pins must be configured
properly. See Table 7 for configuring the device address pins.
Table 7. Strap Boot EEPROM Address Lines to These Values
Bytes
For designers migrating from the FX2 to the FX2LP, a change in
the bill of material and review of the memory allocation (due to
increased internal memory) is required. For more information
about migrating from EZ-USB FX2 to EZ-USB FX2LP, see the
application note titled Migrating from EZ-USB FX2 to EZ-USB
FX2LP available in the Cypress web site.

2.18.2 I2C Interface Boot Load Access
At power-on reset, the I2C interface boot loader loads the
VID/PID/DID configuration bytes and up to 16 KB of
program/data. The available RAM spaces are 16 KB from
0x0000–0x3FFF and 512 bytes from 0xE000–0xE1FF. The 8051
is in reset. I2C interface boot loads only occur after power-on
reset.

CY7C68013A is identical to CY7C68014A in form, fit, and
functionality. CY7C68015A is identical to CY7C68016A in form,
fit, and functionality. CY7C68014A and CY7C68016A have a
lower suspend current than CY7C68013A and CY7C68015A
respectively and are ideal for power-sensitive battery
applications.
The 8051 can control peripherals connected to the I2C bus using
the I2CTL and I2DAT registers. FX2LP provides I2C master
control only; it is never an I2C slave.
CY7C68015A and CY7C68016A are available in 56-pin QFN
package only. Two additional GPIO signals are available on the
CY7C68015A and CY7C68016A to provide more flexibility when
neither IFCLK or CLKOUT are needed in the 56-pin package.
2.19 Compatible with Previous Generation
EZ-USB FX2
USB developers wanting to convert their FX2 56-pin application
to a bus-powered system directly benefit from these additional
signals. The two GPIOs give developers the signals they need
for the power-control circuitry of their bus-powered application
without pushing them to a high-pincount version of FX2LP.
The EZ-USB FX2LP is form-, fit-, and with minor exceptions,
functionally-compatible with its predecessor, the EZ-USB FX2.
This makes for an easy transition for designers wanting to
upgrade their systems from the FX2 to the FX2LP. The pinout
and package selection are identical and a vast majority of
firmware previously developed for the FX2 functions in the
FX2LP.
The CY7C68015A is only available in the 56-pin QFN package

3. Pin Assignments
Figure 3-1 on page 17 identifies all signals for the five package
types. The following pages illustrate the individual pin diagrams,
plus a combination diagram showing which of the full set of
signals are available in the 128-pin, 100-pin, and 56-pin
packages.
The signals on the left edge of the 56-pin package in Figure 3-1
on page 17 are common to all versions in the FX2LP family with
the noted differences between the CY7C68013A/14A and the
CY7C68015A/16A.
The 128-pin package adds the 8051 address and data buses
plus control signals. Note that two of the required signals, RD#
and WR#, are present in the 100-pin version.
In the 100-pin and 128-pin versions, an 8051 control bit can be
set to pulse the RD# and WR# pins when the 8051 reads
from/writes to PORTC. This feature is enabled by setting the
PORTCSTB bit in the CPUCS register.
Section 9.5 displays the timing diagram of the read and write
strobing function on accessing PORTC.
Three modes are available in all package versions: Port, GPIF
master, and Slave FIFO. These modes define the signals on the
right edge of the diagram. The 8051 selects the interface mode
using the IFCONFIG[1:0] register bits. Port mode is the power on
default configuration.
The 100-pin package adds functionality to the 56-pin package by
adding these pins:
■
PORTC or alternate GPIFADR[7:0] address signals
■
PORTE or alternate GPIFADR[8] address signal and seven
additional 8051 signals
■
Three GPIF Control signals
■
Four GPIF Ready signals
■
Nine 8051 signals (two USARTs, three timer inputs, INT4, and
INT5#)
■
BKPT, RD#, WR#.

USB D+ Signal. Connect to the USB D+ signal.
8051 Address Bus. This bus is driven at all times.
When the 8051 is addressing internal RAM it reflects
the internal address.
8051 Data Bus. This bidirectional bus is
high impedance when inactive, input for bus reads,
and output for bus writes. The data bus is used for
external 8051 program and data memory. The data
bus is active only for external bus accesses, and is
driven LOW in suspend.
Program Store Enable. This active LOW signal
indicates an 8051 code fetch from external memory.
It is active for program memory fetches from
0x4000–0xFFFF when the EA pin is LOW, or from
0x0000–0xFFFF when the EA pin is HIGH.
Notes
11. Unused inputs must not be left floating. Tie either HIGH or LOW as appropriate. Outputs should only be pulled up or down to ensure signals at power up and in standby.
Note also that no pins should be driven while the device is powered down.
12. The Reset column indicates the state of signals during reset (RESET# asserted) or during Power on Reset (POR).

Description
Output
L
L
Breakpoint. This pin goes active (HIGH) when the
8051 address bus matches the BPADDRH/L
registers and breakpoints are enabled in the
BREAKPT register (BPEN = 1). If the BPPULSE bit
in the BREAKPT register is HIGH, this signal pulses
HIGH for eight 12-/24-/48-MHz clocks. If the
BPPULSE bit is LOW, the signal remains HIGH until
the 8051 clears the BREAK bit (by writing 1 to it) in
the BREAKPT register.
RESET#
Input
N/A
N/A
Active LOW Reset. Resets the entire chip. See
section 2.9 ”Reset and Wakeup” on page 9 for more

EA
Input
N/A
N/A
External Access. This pin determines where the
8051 fetches code between addresses 0x0000 and
0x3FFF. If EA = 0 the 8051 fetches this code from
its internal RAM. IF EA = 1 the 8051 fetches this
code from external memory.

It is also correct to drive XTALIN with an external
24-MHz square wave derived from another clock
source. When driving from an external source, the
driving signal should be a 3.3-V square wave.

Where,
P = Power
Ja = Junction to ambient temperature (Jc + Ca)
a = Ambient temperature (70 °C)
The case temperature c, can be calculated using the following equation: c = P*Ca + a
where,
P = Power
Ca = Case to ambient temperature
a = Ambient temperature (70 °C)
Note
17. Do not power I/O with the chip power OFF.

When using the AUTPOPTR1 or AUTOPTR2 to address external memory, the address of AUTOPTR1 is only active while either
RD# or WR# is active. The address of AUTOPTR2 is active throughout the cycle and meets the address valid time for which is
based on the stretch value.
Notes
21. The stretch memory cycle feature enables EZ-USB firmware to adjust the speed of data memory accesses not the program memory accesses. Details including
typical strobe width timings can be found in the section 12.1.2 of the Technical Reference Manual. The address cycle width can be interpreted from these.
22. tACC2 and tACC3 are computed from these parameters as follows:
tACC2(24 MHz) = 3*tCL – tAV –tDSU = 106 ns
tACC2(48 MHz) = 3*tCL – tAV – tDSU = 43 ns
tACC3(24 MHz) = 5*tCL – tAV –tDSU = 190 ns
tACC3(48 MHz) = 5*tCL – tAV – tDSU = 86 ns

9.5 PORTC Strobe Feature Timings
The RD# and WR# are present in the 100-pin version and the
128-pin package. In these 100-pin and 128-pin versions, an
8051 control bit can be set to pulse the RD# and WR# pins when
the 8051 reads from or writes to PORTC. This feature is enabled
by setting PORTCSTB bit in CPUCS register.
The RD# signal prompts the external logic to prepare the next
data byte. Nothing gets sampled internally on assertion of the
RD# signal itself; it is just a prefetch type signal to get the next
data byte prepared. So, using it with that in mind easily meets the
setup time to the next read.
The RD# and WR# strobes are asserted for two CLKOUT cycles
when PORTC is accessed.
The purpose of this pulsing of RD# is to allow the external
peripheral to know that the 8051 is done reading PORTC and the
data was latched into PORTC three CLKOUT cycles before
asserting the RD# signal. After the RD# is pulsed, the external
logic can update the data on PORTC.
The WR# strobe is asserted two clock cycles after PORTC is
updated and is active for two clock cycles after that, as shown in
Figure 9-4.
As for read, the value of PORTC three clock cycles before the
assertion of RD# is the value that the 8051 reads in. The RD# is
pulsed for two clock cycles after three clock cycles from the point
when the 8051 has performed a read function on PORTC.
Following is the timing diagram of the read and write strobing
function on accessing PORTC. Refer to Section 9.3 and Section
9.4 for details on propagation delay of RD# and WR# signals.

caused the last byte or word to be clocked into the previous auto
committed packet. Figure 9-12 shows this scenario. X is the
value the AUTOINLEN register is set to when the IN endpoint is
configured to be in auto mode.
There is no specific timing requirement that should be met for
asserting the PKTEND pin to asserting SLWR. PKTEND can be
asserted with the last data value clocked into the FIFOs or
thereafter. The setup time tSPE and the hold time tPEH must be
met.
Figure 9-12 shows a scenario where two packets are committed.
The first packet gets committed automatically when the number
of bytes in the FIFO reaches X (value set in AUTOINLEN
register) and the second one byte/word short packet being
committed manually using PKTEND.
Although there are no specific timing requirements for PKTEND
assertion, there is a specific corner-case condition that needs
attention while using the PKTEND pin to commit a one byte or
word packet. There is an additional timing requirement that
needs to be met when the FIFO is configured to operate in auto
mode and it is required to send two packets back to back: a full
packet (full defined as the number of bytes in the FIFO meeting
the level set in AUTOINLEN register) committed automatically
followed by a short one byte or word packet committed manually
using the PKTEND pin. In this scenario, the user must ensure to
assert PKTEND, at least one clock cycle after the rising edge that
Note that there is at least one IFCLK cycle timing between the
assertion of PKTEND and clocking of the last byte of the previous
packet (causing the packet to be committed automatically).
Failing to adhere to this timing results in the FX2 failing to send
the one byte or word short packet.

Figure 9-18 on page 52 shows the timing relationship of the
SLAVE FIFO signals during a synchronous FIFO read using
IFCLK as the synchronizing clock. The diagram illustrates a
single read followed by a burst read.
■
At t = 0, the FIFO address is stable and the signal SLCS is
asserted (SLCS may be tied LOW in some applications). Note
that tSFA has a minimum of 25 ns. This meansthat when IFCLK
is running at 48 MHz, the FIFO address setup time is more than
one IFCLK cycle.
■
At t = 1, SLOE is asserted. SLOE is an output enable only,
whose sole function is to drive the data bus. The data that is
driven on the bus is the data that the internal FIFO pointer is
currently pointing to. In this example it is the first data value in
the FIFO. Note: the data is prefetched and is driven on the bus
when SLOE is asserted.
■
At t = 2, SLRD is asserted. SLRD must meet the setup time of
tSRD (time from asserting the SLRD signal to the rising edge of
the IFCLK) and maintain a minimum hold time of tRDH (time
from the IFCLK edge to the deassertion of the SLRD signal).
If the SLCS signal is used, it must be asserted before SLRD is
asserted (The SLCS and SLRD signals must both be asserted
to start a valid read condition).
The FIFO pointer is updated on the rising edge of the IFCLK,
while SLRD is asserted. This starts the propagation of data
from the newly addressed location to the data bus. After a
propagation delay of tXFD (measured from the rising edge of
IFCLK) 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 are shown for a burst read and
are marked with the time indicators of T = 0 through 5.
Note For the burst mode, the SLRD and SLOE are left asserted
during the entire duration of the read. In the burst read mode,
when SLOE is asserted, data indexed by the FIFO pointer is on
the data bus. During the first read cycle, on the rising edge of the
clock, the FIFO pointer is updated and incremented to point to
address N+1. For each subsequent rising edge of IFCLK, while
the SLRD is asserted, the FIFO pointer is incremented and the
next data value is placed on the data bus.

Figure 9-20 shows the timing relationship of the SLAVE FIFO
signals during a synchronous write using IFCLK as the
synchronizing clock. The diagram illustrates a single write
followed by burst write of three bytes and committing all four
bytes as a short packet using the PKTEND pin.
■
At t = 0 the FIFO address is stable and the signal SLCS is
asserted. (SLCS may be tied LOW in some applications) Note
that tSFA has a minimum of 25 ns. This means when IFCLK is
running at 48 MHz, the FIFO address setup time is more than
one IFCLK cycle.
■
At t = 1, the external master/peripheral must outputs the data
value onto the data bus with a minimum set up time of tSFD
before the rising edge of IFCLK.
■
At t = 2, SLWR is asserted. The SLWR must meet the setup
time of tSWR (time from asserting the SLWR signal to the rising
edge of IFCLK) and maintain a minimum hold time of tWRH (time
from the IFCLK edge to the deassertion of the SLWR signal).
If the SLCS signal is used, it must be asserted with SLWR or
before SLWR is asserted (The SLCS and SLWR signals must
both be asserted to start a valid write condition).
■
While the SLWR is asserted, data is written to the FIFO and on
the rising edge of the IFCLK, the FIFO pointer is incremented.
The FIFO flag is also updated after a delay of tXFLG from the
rising edge of the clock.
There is no specific timing requirement that should be met for
asserting PKTEND signal with regards to asserting the SLWR
signal. PKTEND can be asserted with the last data value or
thereafter. The only requirement is that the setup time tSPE and
the hold time tPEH must be met. In the scenario of Figure 9-20,
the number of data values committed includes the last value
written to the FIFO. In this example, both the data value and the
PKTEND signal are clocked on the same rising edge of IFCLK.
PKTEND can also be asserted in subsequent clock cycles. The
FIFOADDR lines should be held constant during the PKTEND
assertion.
Although there are no specific timing requirement for the
PKTEND assertion, there is a specific corner-case condition that
needs attention while using the PKTEND to commit a one
byte/word packet. Additional timing requirements exist when the
FIFO is configured to operate in auto mode and it is desired to
send two packets: a full packet (‘full’ defined as the number of
bytes in the FIFO meeting the level set in the AUTOINLEN
register) committed automatically followed by a short one byte or
word packet committed manually using the PKTEND pin.
In this case, the external master must ensure to assert the
PKTEND pin at least one clock cycle after the rising edge that
caused the last byte or word that needs to be clocked into the
previous auto committed packet (the packet with the number of
bytes equal to what is set in the AUTOINLEN register). Refer to
Figure 9-12 on page 50 for further details on this timing.
The same sequence of events are also shown for a burst write
and are marked with the time indicators of T = 0 through 5.
Note For the burst mode, SLWR and SLCS are left asserted for
the entire duration of writing all the required data values. 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
IFCLK. The FIFO pointer is updated on each rising edge of
IFCLK. In Figure 9-20, after the four bytes are written to the
FIFO, SLWR is deasserted. The short 4 byte packet can be
committed to the host by asserting the PKTEND signal.

Figure 9-21 shows the timing relationship of the SLAVE FIFO
signals during an asynchronous FIFO read. It shows a single
read followed by a burst read.
■
The data that is driven, after asserting SLRD, is the updated
data from the FIFO. This data is valid after a propagation delay
of tXFD from the activating edge of SLRD. In Figure 9-21, data
N is the first valid data read from the FIFO. For data to appear
on the data bus during the read cycle (SLRD is asserted), SLOE
must be in an asserted state. SLRD and SLOE can also be tied
together.
■
At t = 0, the FIFO address is stable and the SLCS signal is
asserted.
■
At t = 1, SLOE is asserted. This results in the data bus being
driven. The data that is driven on to the bus is the previous
data, the data that was in the FIFO from anearlier read cycle.
The same sequence of events is also shown for a burst read
marked with T = 0 through 5.
At t = 2, SLRD is asserted. The SLRD must meet the minimum
active pulse of tRDpwl and minimum de-active pulse width of
tRDpwh. If SLCS is used, then SLCS must be asserted before
SLRD is asserted (The SLCS and SLRD signals must both be
asserted to start a valid read condition.)
Note In the burst read mode, during SLOE is asserted, the data
bus is in a driven state and outputs the previous data. After SLRD
is asserted, the data from the FIFO is driven on the data bus
(SLOE must also be asserted) and then the FIFO pointer is
incremented.

Figure 9-23 shows the timing relationship of the SLAVE FIFO
write in an asynchronous mode. The diagram shows a single
write followed by a burst write of 3 bytes and committing the
4byte short packet using PKTEND.
■
At t = 0 the FIFO address is applied, ensuring that it meets the
setup time of tSFA. If SLCS is used, it must also be asserted
(SLCS may be tied LOW in some applications).
■
At t = 1 SLWR is asserted. SLWR must meet the minimum
active pulse of tWRpwl and minimum de-active pulse width of
tWRpwh. If the SLCS is used, it must be asserted with SLWR or
before SLWR is asserted.
■
At t = 2, data must be present on the bus tSFD before the
deasserting edge of SLWR.
■
At t = 3, deasserting SLWR causes the data to be written from
the data bus to the FIFO and then increments the FIFO pointer.
The FIFO flag is also updated after tXFLG from the deasserting
edge of SLWR.
Document Number: 38-08032 Rev. *X
The same sequence of events is shown for a burst write and is
indicated by the timing marks of T = 0 through 5.
Note In the burst write mode, after SLWR is deasserted, the data
is written to the FIFO and then the FIFO pointer is incremented
to the next byte in the FIFO. The FIFO pointer is post
incremented.
In Figure 9-23, after the four bytes are written to the FIFO and
SLWR is deasserted, the short 4-byte packet can be committed
to the host using PKTEND. The external device should be
designed to not assert SLWR and the PKTEND signal at the
same time. It should be designed to assert the PKTEND after
SLWR is deasserted and met the minimum deasserted pulse
width. The FIFOADDR lines have to held constant during the
PKTEND assertion.

12. PCB Layout Recommendations
Follow these recommendations to ensure reliable
highperformance operation:[29]
■
Bypass and flyback caps on VBUS, near connector, are
recommended.
■
Four-layer, impedance-controlled boards are required to
maintain signal quality.
■
■
Specify impedance targets (ask your board vendor what they
can achieve).
DPLUS and DMINUS trace lengths should be kept to within
2 mm of each other in length, with preferred length of 20 to
30 mm.
■
Maintain a solid ground plane under the DPLUS and DMINUS
traces. Do not allow the plane to split under these traces.
■
Do not place vias on the DPLUS or DMINUS trace routing.
■
Isolate the DPLUS and DMINUS traces from all other signal
traces by no less than 10 mm.
■
To control impedance, maintain trace widths and trace spacing.
■
Minimize stubs to minimize reflected signals.
■
Connections between the USB connector shell and signal
ground must be near the USB connector.

13. Quad Flat Package No Leads (QFN) Package Design Notes
Electrical contact of the part to the PCB is made by soldering the
leads on the bottom surface of the package to the PCB.
Therefore, special attention is required to the heat transfer area
below the package to provide a good thermal bond to the circuit
board. Design a copper (Cu) fill in the PCB as a thermal pad
under the package. Heat is transferred from the FX2LP through
the device’s metal paddle on the bottom side of the package.
Heat from here is conducted to the PCB at the thermal pad. It is
then conducted from the thermal pad to the PCB inner ground
plane by a 5 × 5 array of via. A via is a plated-through hole in the
PCB with a finished diameter of 13 mil. The QFN’s metal die
paddle must be soldered to the PCB’s thermal pad. Solder mask
is placed on the board top side over each via to resist solder flow
into the via. The mask on the top side also minimizes outgassing
during the solder reflow process.
For further information on this package design, refer to
application notes for Surface Mount Assembly of Amkor's
MicroLeadFrame (MLF) Packages. You can find this on Amkor's
website http://www.amkor.com.
This application note provides detailed information about
boardmounting guidelines, soldering flow, rework process, etc.
Figure 13-1 shows a cross-sectional area underneath the
package. The cross section is of only one via. The solder paste
template should be designed to allow at least 50% solder
coverage. The thickness of the solder paste template should be
5 mil. Use the No Clean type 3 solder paste for mounting the part.
Nitrogen purge is recommended during reflow.
Figure 13-2 is a plot of the solder mask pattern and Figure 13-3
displays an X-Ray image of the assembly (darker areas indicate
solder).

[1] Empty Flag Assertion
1. Empty Flag Assertion
■
Problem Definition
In Slave FIFO Asynchronous Word Wide mode, if a single word data is transferred from the USB host to EP2, configured as OUT
Endpoint (EP) in the first transaction, then the Empty flag behaves incorrectly. This does not happen if the data size is more than
one word in the first transaction.
■
Parameters Affected
NA
■
Trigger Condition(S)
In Slave FIFO Asynchronous Word Wide Mode, after firmware boot and initialization, EP2 OUT endpoint empty flag indicates the
status as ‘Empty’. When data is received in EP2, the status changes to ‘Not-Empty’. However, if data transferred to EP2 is a single
word, then asserting SLRD with FIFOADR pointing to any other endpoint changes ‘Not-Empty’ status to ‘Empty’ for EP2 even
though there is a word data (or it is untouched). This is noticed only when the single word is sent as the first transaction and not if
it follows a multi-word packet as the first transaction.
■
Scope of Impact
External interface does not see data available in EP2 OUT endpoint and can end up waiting for data to be read.
■
Workaround
One of the following workarounds can be used:
• Send a pulse signal to the SLWR pin, with FIFOADR pins pointing to an endpoint other than EP2, after firmware initialization
and before or after transferring the data to EP2 from the host
• Set the length of the first data to EP2 to be more than a word
• Prioritize EP2 read from the Master for multiple OUT EPs and single word write to EP2
• Write to an IN EP, if any, from the Master before reading from other OUT EPs (other than EP2) from the Master.
■
Fix Status
There is no silicon fix planned for this currently; use the workarounds provided.
