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 (W) and Read

(R) 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 (RT) 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 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 MIL-STD-883, Class B.
