DESCRIPTION:
The IDT6198 is a 65,536-bit high-speed static RAM orga-
nized as 16K x 4. It is fabricated using IDT’s high-perfor-
mance, high-reliability technology—CMOS. 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
CS
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
μ
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.
