CY7C419/21/25/29/33

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

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

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

Features

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

• 256 x 9 (CY7C419)

• 512 x 9 (CY7C421)

• 1K x 9 (CY7C425)

• 2K x 9 (CY7C429)

flags are provided to prevent overrun and underrun. Three ad-

ditional 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.

• 4K x 9 (CY7C433)

• Dual-ported RAM cell

• 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

• Retransmit in standalone

• Expandable in width

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

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.

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

dalone and width expansion configurations. In the depth ex-

pansion configuration, this pin provides the expansion out

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

activated.

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

Functional Description

The CY7C419, CY7C420, CY7C421, CY7C424, CY7C425,

CY7C428, CY7C429, CY7C432, and CY7C433 are fabricated

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

put ESD protection is greater than 2000V and latch-up is pre-

vented by careful layout and guard rings.

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

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

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.
