CY7C4425V/4235V/4245V

64/256/512/1K/2K/4K x18 Low-Voltage Synchronous FIFOs

Features

Functional Description

• 3.3V operation for low power consumption and easy

integration into low-voltage systems

The CY7C42X5V are high-speed, low-power, first-in first-out

(FIFO) memories with clocked read and write interfaces. All

are 18 bits wide. The CY7C42X5V can be cascaded to

increase FIFO depth. Programmable features include Almost

Full/Almost Empty flags. These FIFOs provide solutions for a

wide variety of data buffering needs, including high-speed data

acquisition, multiprocessor interfaces, and communications

buffering.

• High-speed, low-power, first-in first-out (FIFO)

memories

• 64 x 18 (CY7C4425V)

• 256 x 18 (CY7C4205V)

• 512 x 18 (CY7C4215V)

• 1K x 18 (CY7C4225V)

• 2K x 18 (CY7C4235V)

• 4K x 18 (CY7C4245V)

• 0.65µ CMOS

These FIFOs have 18-bit input and output ports that are

controlled by separate clock and enable signals. The input port

is controlled by a Free-Running Clock (WCLK) and a Write

Enable pin (WEN).

When WEN is asserted, data is written into the FIFO on the

rising edge of the WCLK signal. While WEN is held active, data

is continually written into the FIFO on each cycle. The output

port is controlled in a similar manner by a Free-Running Read

Clock (RCLK) and a Read Enable pin (REN). In addition, the

CY7C42X5V have an Output Enable pin (OE). The read and

write clocks may be tied together for single-clock operation or

the two clocks may be run independently for asynchronous

read/write applications. Clock frequencies up to 66 MHz are

achievable.

• High-speed 67-MHz operation (15-ns read/write cycle

times)

• Low power

— I_CC= 30 mA

• 5V tolerant inputs (V_{IH MAX}= 5V)

• Fully asynchronous and simultaneous read and write

operation

Retransmit and Synchronous Almost Full/Almost Empty flag

features are available on these devices.

• Empty, Full, HalfFull, andprogrammableAlmostEmpty

and Almost Full status flags

Depth expansion is possible using the Cascade Input (WXI,

RXI), Cascade Output (WXO, RXO), and First Load (FL) pins.

The WXO and RXO pins are connected to the WXI and RXI

pins of the next device, and the WXO and RXO pins of the last

device should be connected to the WXI and RXI pins of the

first device. The FL pin of the first device is tied to V_SSand the

• TTL-compatible

• Retransmit function

• Output Enable (OE) pin

• Independent read and write enable pins

• Supports free-running 50% duty cycle clock inputs

• Width-Expansion Capability

FL pin of all the remaining devices should be tied to V_CC

The CY7C42X5V provides five status pins. These pins are

decoded to determine one of five states: Empty, Almost Empty,

Half Full, Almost Full, and Full (see Table 2). The Half Full flag

shares the WXO pin. This flag is valid in the stand-alone and

width-expansion configurations. In the depth expansion, this

pin provides the expansion out (WXO) information that is used

to signal the next FIFO when it will be activated.

• Depth-Expansion Capability

• 64-pin 14 × 14 TQFP and 64-pin 10 × 10 STQFP

• Pb-Free packages available

The Empty and Full flags are synchronous, i.e., they change

state relative to either the Read Clock (RCLK) or the write

clock (WCLK). When entering or exiting the Empty states, the

flag is updated exclusively by the RCLK. The flag denoting Full

states is updated exclusively by WCLK. The synchronous flag

architecture guarantees that the flags will remain valid from

one clock cycle to the next. As mentioned previously, the

Almost Empty/Almost Full flags become synchronous if the

_CC/SMODE is tied to V_SS. All configurations are fabricated

using an advanced 0.65µ P-Well CMOS technology. Input

ESD protection is greater than 2001V, and latch-up is

prevented by the use of guard rings.
