Description

The IDT70V38 is a high-speed 64K x 18 Dual-Port Static RAM.

The IDT70V38 is designed to be used as a stand-alone 1152K-bit

Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM

for 36-bit-or-more word system. Using the IDT MASTER/SLAVE

Dual-Port RAM approach in 36-bit or wider memory system applica-

tions 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

permit 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 440mW of power.

The IDT70V38 is packaged in a 100-pin Thin Quad Flatpack

(TQFP).

NOTES:

1. All Vcc pins must be connected to power supply.

2. All GND pins must be connected to ground.

3. 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.
