70V05L
HIGH-SPEED 3.3V
8K x 8 DUAL-PORT
STATIC RAM
70V05S/L
Features
True Dual-Ported memory cells which allow simultaneous
reads of the same memory location
High-speed access
– Commercial: 15ns (max.)
– Industrial: 20ns (max.)

High-Speed 3.3V 8K x 8 Dual-Port Static RAM
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-morewordsystems. UsingtheIDTMASTER/SLAVEDual-PortSRAM
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
Industrial and Commercial Temperature Ranges
reads or writes to any location in memory. An automatic power down
featurecontrolledby CEpermitstheon-chipcircuitryofeachporttoenter
a very low standby power mode.
Fabricated using CMOS high-performance technology, these de-
vices 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).
