Description
The lDT61298SA is a 262,144-bit high-speed static RAM organized
as 64K x 4. It is fabricated using IDT’s high-performance, high-reliability
CMOS technology. This state-of-the-art technology, combined with inno-
vative circuit design techniques, provides a cost-effective approach for
memory intensive applications.
The IDT61298SA features two memory control functions: Chip Select
(CS) and Output Enable (OE). These two functions greatly enhance the
IDT61298SA's overall flexibility in high-speed memory applications.
Access times as fast as 12ns are available. The IDT61298SA offers
a reduced power standby mode, ISB1, which enables the designer to
considerably reduce device power requirements. This capability signifi-
cantly decreases system power and cooling levels, while greatly enhanc-
ing system reliability.
All inputs and outputs are TTL-compatible and the device operates from
a single 5V supply. Fully static asynchronous circuitry, along with matching
access and cycle times, favor the simplified system design approach.
The IDT61298SA is packaged in a 300 mil, 28-pin SOJ, providing
improved board-level packing densities.
