FEATURES:

DESCRIPTION:

• High-speed clock-to-data output times

— Military: 20/25/30ns (max.)

— Commercial: 15/20/25ns (max.)

• Low-power operation

The IDT7099 is a high-speed 4K x 9 bit synchronous Dual-

Port RAM. The memory array is based on Dual-Port memory

cells toallowsimultaneousaccessfrombothports. Registers

on control, data, and address inputs provide low set-up and

hold times. The timing latitude provided by this approach

allow systems to be designed with very short realized cycle

times. With an input data register, this device has been

optimized for applications having unidirectional data flow or

bi-directionaldataflowinbursts. Changingdatadirectionfrom

— IDT7099S

Active: 900 mW (typ.)

Standby: 50 mW (typ.)

• Architecture based on Dual-Port RAM cells

— Allows full simultaneous access from both ports

— Independent bit/byte Read and Write inputs for control reading to writing normally requires one dead cycle.

functions

• Synchronous operation

— 4ns setup to clock, 1ns hold on all control, data, and

address inputs

— Data input, address, and control registers

— Fast 15ns clock to data out

These Dual-Ports typically operate on only 900mW of

power at maximum high-speed clock-to-data output times as

fast as 15ns. An automatic power down feature, controlled

by CE,permitstheon-chipcircuitryofeachport toenteravery

low standby power mode.

The IDT7099 is packaged in a 68-pin PGA, 68-pin PLCC,

and a 80-pin TQFP. Military grade product is manufactured in

compliance with the latest revision of MIL-STD-883, Class B,

making it ideally suited to military temperature applications

demanding the highest level of performance and reliability.

— 20ns cycle times, 50MHz operation

• Clock enable feature

• Guaranteed data output hold times

• Available in 68-pin PGA, 68-pin PLCC, and 80-pin TQFP

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

• Industrial temperature range (–40°C to +85°C) is avail-

able, tested to military electrical specifications
