Functional Description

The CY7C42X1V are high-speed, low-power, FIFO memories

with clocked read and write interfaces. All are nine bits wide.

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, multi-

processor interfaces, and communications buffering.

These FIFOs have 9-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 two Write

Enable pins (WEN1, WEN2/LD).

• High-speed 66-MHz operation (15-ns read/write cycle

time)

• Low power (I_CC= 20 mA)

When WEN1 is LOW and WEN2/LD is HIGH, data is written

into the FIFO on the rising edge of the WCLK signal. While

WEN1, WEN2/LD is held active, data is continually written into

the FIFO on each WCLK cycle. The output port is controlled in

a similar manner by a Free-Running Read Clock (RCLK) and

two Read Enable Pins (REN1, REN2). In addition, the

CY7C42X1V has an Output Enable Pin (OE). The Read

(RCLK) and Write (WCLK) clocks may be tied together for

single-clock operation or the two clocks may be run indepen-

dently for asynchronous read/write applications. Clock

frequencies up to 66 MHz are achievable.

• 3.3V operation for low power consumption and easy

integration into low-voltage systems

• 5V-tolerant inputs V_{IH max}= 5V

• Fully asynchronous and simultaneous read and write

operation

• Empty, Full, and Programmable Almost Empty and

Almost Full status flags

• TTL compatible

• Output Enable (OE) pin

Depth expansion is possible using one enable input for system

control, while the other enable is controlled by expansion logic

to direct the flow of data.

• Independent read and write enable pins

• Center power and ground pins for reduced noise

• Width expansion capability
