IDT71128

Description

The IDT71128 is a 1,048,576-bit high-speed static RAM

organized as 256K x 4. It is fabricated using IDT’s high-perfor-

mance, high-reliability CMOS technology. This state-of-the-art

technology, combined with innovative circuit design techniques,

provides a cost-effective solution for high-speed memory needs.

The JEDEC centerpower/GND pinout reduces noise generation

and improves system performance.

The IDT71128 has an output enable pin which operates as fast

as 6ns, with address access times as fast as 12ns available. All

bidirectional inputs and outputs of the IDT71128 are TTL-compat-

ible and operation is from a single 5V supply. Fully static asyn-

chronous circuitry is used; no clocks or refreshes are required for

operation.

The IDT71128 is packaged in a 32-pin 400 mil Plastic SOJ.

◆

256K x 4 advanced high-speed CMOS static RAM

JEDEC revolutionary pinout (center power/GND) for

reduced noise.

Equal access and cycle times

— Commercial and Industrial: 12/15/20ns

One Chip Select plus one Output Enable pin

Bidirectional inputs and outputs directly

TTL-compatible

Low power consumption via chip deselect

Available in a 32-pin 400 mil Plastic SOJ.
