7202/7203/7204. These devices load and empty data on a

first-in/first-out basis. They 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.

FEATURES:

• 3.3V family uses 70% less power than the 5 Volt 7201/

02/03/04 family

• 512 x 9 organization (72V01)

• 1024 x 9 organization (72V02)

The reads and writes are internally sequential through the

use of ring pointers, with no address information required to

loadandunloaddata. Dataistoggledinandoutofthedevices

throughtheuseoftheWrite(W)andRead(R)pins. Thedevices

have a maximum data access time as fast as 25 ns.

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

errorchecking. TheyalsofeatureaRetransmit(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.

• 2048 x 9 organization (72V03)

• 4096 X 9 organization (72V04)

• Functionally compatible with 720x family

• 25 ns access time

• Asynchronous and simultaneous read and write

• Fully expandable by both word depth and/or bit width

• Status Flags: Empty, Half-Full, Full

• Auto-retransmit capability

• Available in 32-pin PLCC and 28-pin SOIC Package (to

be determined)

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

able, tested to military electrical specifications

DESCRIPTION:

The IDT72V01/72V02/72V03/72V04 is fabricated using

IDT’shigh-speedCMOStechnology. Ithasbeendesignedfor

those applications requiring asynchronous and simultaneous

read/writes in multiprocessing and rate buffer applications.

The IDT72V01/72V02/72V03/72V04 are dual-port FIFO

memories that operate at a power supply voltage (Vcc)

between 3.0V and 3.6V. Their architecture, functional opera-

tionandpinassignmentsareidenticaltothoseoftheIDT7201/
