CMOS SyncFIFO

64 x 8, 256 x 8, 512 x 8,

1024 x 8, 2048 x 8 and 4096 x 8

Integrated Device Technology, Inc.

FEATURES:

• 64 x 8-bit organization (IDT72420)

• 256 x 8-bit organization (IDT72200)

• 512 x 8-bit organization (IDT72210)

DESCRIPTION:

The IDT72420/72200/72210/72220/72230/72240

SyncFIFO are very high-speed, low-power First-In, First-

Out (FIFO) memories with clocked read and write controls.

The IDT72420/72200/72210/72220/72230/72240 have a 64,

256, 512, 1024, 2048, and 4096 x 8-bit memory array, respec-

tively. These FIFOs are applicable for a wide variety of data

buffering needs, such as graphics, Local Area Networks

(LANs), and interprocessor communication.

These FIFOs have 8-bit input and output ports. The input

port is controlled by a free-running clock (WCLK), and a write

enable pin (WEN). Data is written into the Synchronous FIFO

on every clock when WEN is asserted. The output port is

controlled by another clock pin (RCLK) and a read enable pin

(REN). The read clock can be tied to the write clock for single

clock operation or the two clocks can run asynchronous of one

another for dual clock operation. An output enable pin (OE) is

provided on the read port for three-state control of the output.

TheseSynchronousFIFOshavetwoend-pointflags, Empty

(EF) and Full (FF). Two partial flags, Almost-Empty (AE) and

Almost-Full (AF), are provided for improved system control.

Thepartial(AE)flagsaresettoEmpty+7andFull-7forAE and

AF respectively.

• 1024 x 8-bit organization (IDT72220)

• 2048 x 8-bit organization (IDT72230)

• 4096 x 8-bit organization (IDT72240)

• 12 ns read/write cycle time (IDT72420/72200/72210)

• 15 ns read/write cycle time (IDT72220/72230/72240)

• Read and write clocks can be asynchronous or

coincidental

• Dual-Ported zero fall-through time architecture

• Empty and Full flags signal FIFO status

• Almost-empty and almost-full flags set to Empty+7 and

Full-7, respectively

• Output enable puts output data bus in high-impedance

state

• Produced with advanced submicron CMOS technology

• Available in 28-pin 300 mil plastic DIP and 300 mil

ceramic DIP

• For surface mount product please see the IDT72421/

72201/72211/72221/72231/72241 data sheet

• Military product compliant to MIL-STD-883, Class B

• Industrial temperature range (-40^OC to +85^OC) is

available, tested to military electrical specifications

The IDT72420/72200/72210/72220/72230/72240 are fabri-

cated using IDT’s high-speed submicron CMOS technology.

Military grade product is manufactured in compliance with the

latest revision of MIL-STD-883, Class B.
