I C™ Bus

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

may be more convenient.)

CC_IO

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.

Buses

This 56-pin package has an 8- or 16-bit ‘FIFO’ bidirectional

data bus, multiplexed on IO ports B and D.

Bus-powered Applications

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-

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

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.

[2]

stabilizes in 200 µs after VCC has reached 3.0V . Figure 3-2

shows a power on reset condition and a reset app lied 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:

Cypress provides an application note which describes and

recommends power on reset implementation and can be found

on the Cypress web site. For more information on reset imple-

mentation for the MoBL-USB™ family of products, visit the

Cypress web site at http://www.cypress.com.

• Port pins. For Port A, B, D pins, extra care must be taken in

shared bus situations.

— Completely unused pins must be pulled to V

GND.

• 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.

• IFCLK, RDY0, RDY1. These pins must be pulled to V

or GND or driven by another chip.

CC_IO

• CTL0-2. If tri-stated via GPIFIDLECTL, these pins must be

pulled to V or GND or driven by another chip.

CC_IO

• RESET#, WAKEUP#. These pins must be pulled to V

or GND or driven by another chip during suspend.

2. If the external clock is powered at the same time as the CY7C680xx and has a stabilization wait period, it must be added to the 200 µs.

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

5. 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.

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

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.

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

the I C specifications for details.

External EEPROM device address pins must be configured

properly. See T a ble 3-6 for configuring the device address

pins.

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.

The 8051 can control peripherals connected to the I C bus

using the I2CTL and I2DAT registers. FX2LP18 provides I C

master control only, it is never an I C slave.

Figure 4-1 identifies all signals for the package. It is followed

by the pin diagram.Three modes are available: 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.

3.18.2 I C Interface Boot Load Access

At power on reset the I C interface boot loader loads the

VID/PID/DID and configuration bytes and up to 16 kBytes of

program/data. The available RAM spaces are 16 kBytes from

mental mode crystal and load capacitor to GND.

If an external clock is used to drive XTALIN, leave this pin open.

12 MHz CLKOUT. 12-, 24- or 48-MHz clock, phase locked to the 24 MHz input

clock. The 8051 defaults to 12 MHz operation. The 8051 may tri-state this

output by setting CPUCS.1 = 1.

Port A

PA0 or

INT0#

I/O/Z

Multiplexed pin whose function is selected by PORTACFG.0

PA0 is a bidirectional IO port pin.

INT0# is the active LOW 8051 INT0 interrupt input signal, which is either

edge triggered (IT0 = 1) or level triggered (IT0 = 0).

(PA0)

PA1 or

INT1#

Multiplexed pin whose function is selected by:

PORTACFG.1

PA1 is a bidirectional IO port pin.

INT1# is the active LOW 8051 INT1 interrupt input signal, which is either

edge triggered (IT1 = 1) or level triggered (IT1 = 0).

(PA1)

PA2 or

SLOE

I/O/Z

Multiplexed pin whose function is selected by two bits:

IFCONFIG[1:0].

PA2 is a bidirectional IO port pin.

SLOE is an input-only output enable with programmable polarity

(FIFOPINPOLAR.4) for the slave FIFO’s connected to FD[7:0] or FD[15:0].

(PA2)

PA3 or

WU2

Multiplexed pin whose function is selected by:

WAKEUP.7 and OEA.3

(PA3)

PA3 is a bidirectional IO port pin.

WU2 is an alternate source for USB Wakeup, enabled by WU2EN bit

(WAKEUP.1) and polarity set by WU2POL (WAKEUP.4). If the 8051 is in

suspend and WU2EN = 1, a transition on this pin starts up the oscillator

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

packet. Figure 9-7 shows this scenario. X is the value the

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

Figure 9-7 shows a scenario where two packets are being

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.

valid read condition).

from the newly addressed location to the data bus. After a

of IFCLK) the new data value is present. N is the first data

value read from the FIFO. In order to have data on the FIFO

data bus, SLOE MUST also be asserted.

• 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

The same sequence of events is shown for a burst read and is

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 increments 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 9-15 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 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

IFCLK. In Figure 9-15, once 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.

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

• At t = 0 the FIFO address is stable and the signal SLCS is

asserted. (SLCS may be tied low in some applications)

Note t

has a minimum of 25 ns. This means that when

IFCLK is running at 48 MHz, the FIFO address set-up time

is more than one IFCLK cycle.

and the hold time t

must be met. In the scenario of

SPE

PEH

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

before the rising edge of IFCLK.

• At t = 2, SLWR is asserted. The SLWR must meet the set-

up time of t (time from asserting the SLWR signal to the

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

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.

Figure 9-16 illustrates 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 t

from the activating edge of SLRD. In Figure 9-

XFD

16, data N is the first valid data read from the FIFO. For data

t o appearonthedatabusduringthereadcycle(forexample,

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 inthe data bus being

driven. The data that is driven on to the bus is previous data;

it is data that was in the FIFO from a prior read cycle.

The same sequence of events is also shown for a burst read

marked with T = 0 through 5. Note In burst read mode, during

SLOE assertion, the data bus is in a driven state and outputs

the previous data. Once 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.

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.
