DESCRIPTION:

•

First-In/First-Out dual-port memory

256 x 9 organization (IDT7200)

512 x 9 organization (IDT7201)

1K x 9 organization (IDT7202)

The IDT7200/7201/7202 are dual-port memories that load

and empty data on a first-in/first-out basis. The devices use

Full and Empty flags to prevent data overflow and underflow

andexpansionlogictoallowforunlimitedexpansioncapability

in both word size and depth.

Low power consumption

— Active: 770mW (max.)

—Power-down: 2.75mW (max.)

Ultra high speed—12ns access time

Asynchronous and simultaneous read and write

Fully expandable by both word depth and/or bit width

Pin and functionally compatible with 720X family

Status Flags: Empty, Half-Full, Full

The reads and writes are internally sequential through the

use of ring pointers, with no address information required to

loadandunloaddata. Dataistoggledinandoutofthedevices

through the use of the Write (W) and Read (R) pins.

The devices utilizes a 9-bit wide data array to allow for

control and parity bits at the user’s option. This feature is

especially useful in data communications applications where

it is necessary to use a parity bit for transmission/reception

error checking. It also features a Retransmit (RT) capability

that allows for reset of the read pointer to its initial position

when RT is pulsed low to allow for retransmission from the

beginning of data. A Half-Full Flag is available in the single

device mode and width expansion modes.

The IDT7200/7201/7202 are fabricated using IDT’s high-

speed CMOS technology. They are designed for those

applications requiring asynchronous and simultaneous read/

writes in multiprocessing and rate buffer applications. Military

grade product is manufactured in compliance with the latest

revision of MIL-STD-883, Class B.
