IDT70V08S/L
High-Speed 3.3.V 64K x 8 Dual-Port Static RAM
Description
The IDT70V08 is a high-speed 64K x 8 Dual-Port Static RAM. The
IDT70V08 is designed to be used as a stand-alone 512K-bit Dual-Port
RAM or as a combination MASTER/SLAVE Dual-Port RAM for 16-bit-
or-more word system. Using the IDT MASTER/SLAVE Dual-Port
RAM 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
Industrial and Commercial Temperature Ranges
for reads or writes to any location in memory. An automatic power
down feature controlled by the chip enables (either CE0 or CE1)
permit the on-chip circuitry of each port to enter a very low standby
power mode.
Fabricated using CMOS high-performance technology,
these devices typically operate on only 550mW of power.
The IDT70V08 is packaged in a 100-pin Thin Quad Flatpack
(TQFP).
