High-Speed 3.3V 8K x 8 Dual-Port Static RAM Industrial and Commercial Temperature Ranges

Description
The IDT70V05 is a high-speed 8K x 8 Dual-Port Static RAM. The
IDT70V05 is designed to be used as a stand-alone 64K-bit Dual-Port
SRAM or as a combination MASTER/SLAVE Dual-Port SRAM for 16-bit-
or-more word systems. Using the IDT MASTER/SLAVE Dual-Port SRAM
approach in 16-bit or wider memory system applications results in full-
speed, error-free operation without the need for additional discrete logic.
This device provides two independent ports with separate control,
address, and I/O pins that permit independent, asynchronous access for
reads or writes to any location in memory. An automatic power down
feature controlled by CE permits the on-chip circuitry of each port to enter
a very low standby power mode.
Fabricated using IDT’s CMOS high-performance technology, these
devices typically operate on only 400mW of power.
The IDT70V05 is packaged in a ceramic 68-pin PGA and PLCC
and a 64-pin thin quad flatpack (TQFP).
