CY7C419/21/25/29/33256/512/1K/2K/4K

x 9 Asynchronous FIFO

CY7C419/21/25/29/33

256/512/1K/2K/4K x 9 Asynchronous FIFO

600-mil wide and 300-mil wide packages. They are, respec-

tively, 256, 512, 1,024, 2,048, and 4,096 words by 9-bits wide.

Features

• Asynchronous first-in first-out (FIFO) buffer memories

• 256 x 9 (CY7C419)

Each FIFO memory is organized such that the data is read in

the same sequential order that it was written. Full and Empty

flags are provided to prevent overrun and underrun. Three

additional pins are also provided to facilitate unlimited

expansion in width, depth, or both. The depth expansion

technique steers the control signals from one device to

another in parallel, thus eliminating the serial addition of

propagation delays, so that throughput is not reduced. Data is

steered in a similar manner.

• 512 x 9 (CY7C421)

• 1K x 9 (CY7C425)

• 2K x 9 (CY7C429)

• 4K x 9 (CY7C433)

• Dual-ported RAM cell

The read and write operations may be asynchronous; each

can occur at a rate of 50.0 MHz. The write operation occurs

when the write (W) signal is LOW. Read occurs when read (R)

goes LOW. The nine data outputs go to the high-impedance

state when R is HIGH.

• High-speed 50.0-MHz read/write independent of

depth/width

• Low operating power: I_CC= 35 mA

• Empty and Full flags (Half Full flag in standalone)

• TTL compatible

A Half Full (HF) output flag is provided that is valid in the

standalone and width expansion configurations. In the depth

expansion configuration, this pin provides the expansion out

(XO) information that is used to tell the next FIFO that it will be

activated.

• Retransmit in standalone

• Expandable in width

• PLCC, 7x7 TQFP, SOJ, 300-mil and 600-mil DIP

• Pb-Free Packages Available

In the standalone and width expansion configurations, a LOW

on the retransmit (RT) input causes the FIFOs to retransmit

the data. Read enable (R) and write enable (W) must both be

HIGH during retransmit, and then R is used to access the data.

• Pin compatible and functionally equivalent to IDT7200,

IDT7201, IDT7202, IDT7203, IDT7204, AM7200, AM7201,

AM7202, AM7203, and AM7204

The CY7C419, CY7C420, CY7C421, CY7C424, CY7C425,

CY7C428, CY7C429, CY7C432, and CY7C433 are fabricated

using an advanced 0.65-micron P-well CMOS technology.

Input ESD protection is greater than 2000V and latch-up is

prevented by careful layout and guard rings.

Functional Description

The CY7C419, CY7C420/1, CY7C424/5, CY7C428/9, and

CY7C432/3 are first-in first-out (FIFO) memories offered in
