High-Speed 3.3V 16K x 8 Dual-Port Static RAM
Industrial and Commercial Temperature Ranges
The IDT70V06 is a high-speed 16K x 8 Dual-Port Static RAM. The
IDT70V06 is designed to be used as a stand-alone 128K-bit Dual-Port
Static RAM or as a combination MASTER/SLAVE Dual-Port Static RAM
for 16-bit-or-more word systems. Using the IDT MASTER/SLAVE Dual-
Port Static RAM approach in 16-bit or wider memory system applications
results in full-speed, error-free operation without the need for additional
discrete logic.
Description
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 CMOS high-performance technology, these de-
vices typically operate on only 400mW of power.
The IDT70V06 is packaged in a 68-pin PLCC and a 64-pin thin quad
flatpack (TQFP).
