FX2LP18 supports the I C 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 either
Two control bits in the USBCS (USB Control and Status)
register control the ReNumeration process: DISCON and

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 does.

USB Boot Methods

Bus-powered Applications
2
During the power-up sequence, internal logic checks the I C
port for the connection of an EEPROM whose first byte is
0xC2. If found, it boot-loads the EEPROM contents into
internal RAM (0xC2 load). If no EEPROM is present, an
external processor must emulate an I C slave. The FX2LP18
does not enumerate using internally stored descriptors (for
example, Cypress’ VID/PID/DID is not used for enumer-

ReNumeration™
FX2LP18 implements an autovector feature for INT2. There
are 27 INT2 (USB) vectors. See the MoBL-USB™ Technical
Reference Manual (TRM) for more details.
Because the FX2LP18’s configuration is soft, one chip can
take on the identities of multiple distinct USB devices.
When first plugged into USB, the FX2LP18 enumerates
automatically and downloads firmware and USB descriptor
tables over the USB cable. Next, the FX2LP18 enumerates
again, this time as a device defined by the downloaded infor-
3.8.2
USB Interrupt Autovectors
The main USB interrupt is shared by 27 interrupt sources. To
save the code and processing time that is normally required to
identify the individual USB interrupt source, the FX2LP18
provides a second level of interrupt vectoring, called ‘Autovec-
toring.’ When a USB interrupt is asserted, the FX2LP18

pushes the program counter onto its stack then jumps to
address 0x0043, where it expects to find a ‘jump’ instruction to
the USB interrupt service routine.
If Autovectoring is enabled (AV2EN = 1 in the INTSET-UP
register), the FX2LP18 substitutes its INT2VEC byte.
Therefore, if the high byte (‘page’) of a jump-table address is
preloaded at location 0x0044, the automatically-inserted
INT2VEC byte at 0x0045 directs the jump to the correct
address out of the 27 addresses within the page.
The FX2LP18 jump instruction is encoded as shown in

The FX2LP18 exits the power-down (USB suspend) state
using one of the following methods:
3.9
Reset and Wakeup
The reset and wakeup pins are described in detail in this
section.
• USB bus activity (if D+/D– lines are left floating, noise on
these lines may indicate activity to the FX2LP18 and initiate
a wakeup)
3.9.1
Reset Pin
• External logic asserts the WAKEUP pin
• External logic asserts the PA3/WU2 pin
The input pin, RESET#, resets the FX2LP18 when asserted.
This pin has hysteresis and is active LOW. When a crystal is
used with the CY7C68053, the reset period must allow for the
stabilization of the crystal and the PLL. This reset period must
be approximately 5 ms after VCC has reached 3.0V. If the
crystal input pin is driven by a clock signal the internal PLL
The second wakeup pin, WU2, can also be configured as a
general purpose IO pin. This allows a simple external R-C
network to be used as a periodic wakeup source. Note that
WAKEUP is by default active LOW.
shows a power on reset condition and a reset applied during
operation. A power on reset is defined as the time reset is
asserted while power is being applied to the circuit. A powered
reset is defined to be when the FX2LP18 has previously been
powered on and operating and the RESET# pin is asserted.
3.9.3
Lowering Suspend Current
Good design practices for CMOS circuits dictate that any
unused input pins must not be floating between V and V .
Floating input pins will not damage the chip, but can substan-
tially increase suspend current. To achieve the lowest suspend
current, any unused port pins must be configured as outputs.
Any unused input pins must be tied to ground. Some examples
of pins that need attention during suspend are:

• CLKOUT. If CLKOUT is not used, it must be tri-stated during
normal operation, but driven during suspend.
3.9.2 Wakeup Pins
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 then the 8051 receives a
wakeup interrupt. This applies whether or not FX2LP18 is
connected to the USB.

pulled to V or GND or driven by another chip.

This mode implements the internal 16-kByte block of RAM
(starting at 0) as combined code and data memory. Only the
internal 16 kBytes and scratch pad 0.5 kBytes RAM spaces
have the following access:
• Bidirectional endpoint zero, 64-byte buffer
• EP1IN, EP1OUT
• USB download

3.12.3 Set-up Data Buffer
A separate 8-byte buffer at 0xE6B8-0xE6BF holds the set-up
data from a CONTROL transfer.
3.12.4 Endpoint Configurations (High-speed Mode)
Endpoints 0 and 1 are the same for every configuration.
Endpoint 0 is the only CONTROL endpoint, and endpoint 1 can
be either BULK or INTERRUPT. The endpoint buffers can be
configured in any one of the 12 configurations shown in the
Document # 001-06120 Rev *F
Page 6 of 39
CY7C68053
BULK mode only the first 64 bytes of each buffer are used. For
example, in high-speed the maximum packet size is 512 bytes,
but in full-speed it is 64 bytes. Even though a buffer is
configured to be a 512 byte buffer, in full-speed only the first
64 bytes are used. The unused endpoint buffer space is not
available for other operations. An example endpoint configu-
ration is:
EP2–1024 double buffered; EP6–512 quad buffered
(column 8).

In Slave (S) mode, the FX2LP18 accepts either an internally
derived clock or externally supplied clock (IFCLK, maximum
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) enables data of the selected width. External
logic must insure 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#.
3.13
External FIFO Interface
The architecture, control signals, and clock rates are
presented in this section.
3.13.1 Architecture
The FX2LP18 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 IO transfer logic.
The transfer logic takes two forms: the GPIF for internally
generated control signals or the slave FIFO interface for exter-
nally controlled transfers.
3.13.3 GPIF and FIFO Clock Rates
3.13.2 Master/Slave Control Signals
An 8051 register bit selects one of two frequencies for the inter-
nally supplied interface clock: 30 MHz and 48 MHz. Alterna-
tively, 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 FIFO’s are internally clocked. An output enable bit in the
IFCONFIG register turns this clock output off. Another bit
within the IFCONFIG register will invert the IFCLK signal
whether internally or externally sourced.
The FX2LP18 endpoint FIFO’s are implemented as eight
physically distinct 256x16 RAM blocks. The 8051/SIE can
switch any of the RAM blocks between two domains, the USB
(SIE) domain and the 8051-IO Unit domain. This switching is
instantaneous, giving zero transfer time between ‘USB FIFO’s’
and ‘Slave FIFO’s.’ Since they are physically the same
memory, no bytes are actually transferred between buffers.
At any given time, some RAM blocks are filling and emptying
with USB data under SIE control, while other RAM blocks are
available to the 8051 and/or the IO control unit. The RAM
blocks operate as single port in the USB domain, and dual port
in the 8051-IO domain. The blocks can be configured as
single, double, triple, or quad buffered as previously shown.
3.14
GPIF
The GPIF is a flexible 8- or 16-bit parallel interface driven by a
user programmable finite state machine. It allows the
CY7C68053 to perform local bus mastering, and can
implement a wide variety of protocols such as ATA interface,
parallel printer port, and Utopia.
The IO 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 two RDY pins can be
used as flag inputs from an external FIFO or other logic. 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 Megabytes/s (48 MHz IFCLK with 16-bit interface).
The GPIF has three programmable control outputs (CTL), and
two 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, and so on. A sequence of the GPIF
vectors make up a single waveform that is executed to perform
the desired data move between the FX2LP18 and the external
device.
Notes

3.14.1 Three Control OUT Signals
3.16
USB Uploads and Downloads
The 56-pin package brings out three of these signals,
CTL0–CTL2. The 8051 programs the GPIF unit to define the
CTL waveforms. CTLx waveform edges can be programmed
to make transitions as fast as once per clock cycle (20.8 ns
using a 48 MHz clock).
The core has the ability to directly edit the data contents of the
internal 16-kByte RAM and of the internal 512-byte scratch
pad RAM via a vendor-specific command. This capability is
normally used when ‘soft’ downloading user code and is
available only to and from internal RAM, only when the 8051
is held in reset. The available RAM spaces are 16 kBytes from
0x0000–0x3FFF (code/data) and 512 bytes from
3.14.2 Two Ready IN Signals
0xE000–0xE1FF (scratch pad data RAM).
The FX2LP18 package brings out all two Ready inputs
(RDY0–RDY1). The 8051 programs the GPIF unit to test the
RDY pins for GPIF branching.
3.17
Autopointer Access
FX2LP18 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.The autopointers are available in external FX2LP18
registers, under control of a mode bit (AUTOPTRSET-UP.0).
Using the external FX2LP18 autopointer access (at 0xE67B –
0xE67C) allows the autopointer to access all RAM. Also, the
autopointers can point to any FX2LP18 register or endpoint
buffer space.
3.14.3 Long Transfer Mode
In master mode, the 8051 appropriately sets GPIF transaction
count registers (GPIFTCB3, GPIFTCB2, GPIFTCB1, or
GPIFTCB0) for unattended transfers of up to 2 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.

ECC Generation[6]
3.18
I C Controller
2
FX2LP18 has one I C port that is driven by two internal
controllers. One automatically operates at boot time to load the
VID/PID/DID, configuration byte, and firmware and a second
controller that the 8051, once running, uses to control external
The MoBL-USB can calculate Error Correcting Codes (ECC’s)
on data that passes across its GPIF or Slave FIFO interfaces.
There are two ECC configurations: two ECC’s, each calculated
over 256 bytes (SmartMedia Standard) and one ECC calcu-
lated over 512 bytes.

I C devices. The I C port operates in master mode only.
The ECC can correct any 1-bit error or detect any 2-bit error.

EEPROM. The pull up resistors used must be such that when
the EEPROM pulls SDA low, the voltage level meets the V

This configuration writes any value to ECCRESET, then
passes 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.

depending on the devices being run on the I C pins. Refer to
2
the I C specifications for details.
External EEPROM device address pins must be configured
pins.
2
If no EEPROM is connected to the I C port, EEPROM
emulation is required by an external processor.This is because
the FX2LP18 comes out of reset with the DISCON bit set, so
the device will not enumerate without an EEPROM (C2 load)
or EEPROM emulation.
3.15.1.2 ECCM = 1
One 3-byte ECC is calculated over a 512-byte block of data.
This configuration writes any value to ECCRESET then
passes 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 value
in ECC1 does not change until ECCRESET is written again,
even if more data is subsequently passed across the interface.
Notes
6. To use the ECC logic, the GPIF or Slave FIFO interface must be configured for byte-wide operation.
7. After the data has been downloaded from the host, a ‘loader’ can execute from internal RAM in order to transfer downloaded data to external memory.

and interrupts the 8051 to allow it to exit the suspend mode. Asserting this
pin inhibits the chip from suspending, if WU2EN = 1.
Note
9. 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

There is no specific timing requirement that needs to be met
for asserting the PKTEND pin with regards to asserting SLWR.
PKTEND can be asserted with the last data value clocked into
the FIFO’s or thereafter. The only consideration is that the set-
one clock cycle after the rising edge that caused the last
byte/word to be clocked into the previous auto committed
AUTOINLEN register is set to when the IN endpoint is
configured to be in auto mode.
up time t
and the hold time t
must be met.
SPE
PEH
Although there are no specific timing requirements 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. There is an additional timing requirement
that needs to be met when the FIFO is configured to operate
in auto mode and you want 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/word packet
committed manually using the PKTEND pin. In this particular
scenario, the user must make sure to assert PKTEND at least
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 is committed manually using PKTEND. 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 FX2LP18 failing to send the
one byte/word short packet.

data bus, SLOE MUST also be asserted.
• At t = 1, SLOE is asserted. SLOE is an output enable only

Figure 9-15 shows the timing relationship of the SLAVE FIFO
signals during a synchronous write using IFCLK as the

followed by burst write of 3 bytes and committing all 4 bytes as
a short packet using the PKTEND pin.
of IFCLK. The FIFO pointer is updated on each rising edge of
FIFO, SLWR is deasserted. The short 4-byte packet can be
committed to the host by asserting the PKTEND signal.
There is no specific timing requirement that needs to be met
for asserting the 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 set-up time

Figure 9-15, 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 must be held constant
during the PKTEND assertion.
• At t = 1, the external master/peripheral must outputthe data
value onto the data bus with a minimum set-up time of t

Although there are no specific timing requirements 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 you want
to send two packets: 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/word packet committed manually using the PKTEND pin.
In this case, the external master must make sure to assert the
PKTEND pin at least one clock cycle after the rising edge that
caused the last byte/word 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 9-7
for further details on this timing.

PCB Layout Recommendations
The following recommendations must be followed to ensure
reliable high-performance operation.
• DPLUS and DMINUS trace lengths must be kept to within
2 mm of each other in length, with preferred length of
20–30 mm.
• At least a four-layer impedance controlled board is required
to maintain signal quality.
• Maintain a solid ground plane under the DPLUS and
DMINUS traces. Do not allow the plane to be split under
these traces.
• Specify impedance targets (ask your board vendor what
they can achieve).
• To control impedance, maintain trace widths and trace spac-
ing to within specifications.
• It is preferable to have no vias placed on the DPLUS or
DMINUS trace routing.
• Minimize stubs to minimize reflected signals.
• Isolate the DPLUS and DMINUS traces from all other signal
traces by no less than 10 mm.
• Connections between the USB connector shell and signal
ground must be done near the USB connector.
