Description
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.
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 IDT70V06 is packaged in a ceramic 68-pin PGA and PLCC
and a 64-pin thin quad flatpack (TQFP).
Pin Configurations

NOTES:
1. All V
CC
pins must be connected to power supply.
2. All GND pins must be connected to ground supply.
3. J68-1 package body is approximately .95 in x .95 in x .17 in
PN-64 package body is approximately 14mm x 14mm x 1.4mm.
4. This package code is used to reference the package diagram.
5. This text does not indicate orientation of the actual part marking.
