DESCRIPTION:

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

and expansion logic to allow for unlimited expansion capability

in both word size and depth.

The reads and writes are internally sequential through the

use of ring pointers, with no address information required to

load and unload data. Data is toggled in and out of the devices

through the use of the Write (

) and Read (

) pins.

The devices utilize 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 (

) capability

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

when

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.

These FIFOs are fabricated using IDT’s high-speed CMOS

technology. They are designed for those applications requir-

ing asynchronous and simultaneous read/writes in multiproc-

essing and rate buffer applications. Military grade product is

manufactured in compliance with the latest revision of MIL-

STD-883, Class B.
