DESCRIPTION:

The IDT6198 is a 65,536-bit high-speed static RAM orga-

nized as 16K x 4. It is fabricated using IDT鈥檚 high-perfor-

mance, high-reliability technology鈥擟MOS. This state-of-the-

art technology, combined with innovative circuit design tech-

niques, provides a cost-effective approach for memory inten-

sive applications. Timing parameters have been specified to

meet the speed demands of the IDT79R3000 RISC proces-

sors.

Access times as fast as 15ns are available. The IDT6198

offers a reduced power standby mode, I

SB1

, which is activated

when

goes HIGH. This capability significantly decreases

system, while enhancing system reliability. The low-power

version (L) also offers a battery backup data retention capa-

bility where the circuit typically consumes only 30碌W when

operating from a 2V battery.

All inputs and outputs are TTL-compatible and operate

from a single 5V supply.

The IDT6198 is packaged in either a 24-pin 300 mil CERDIP,

28-pin leadless chip carrier or 24-pin J-bend small outline IC.

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.
