Description

The IDT70V35/34 (IDT70V25/24) is a high-speed 8/4K x 18 (8/4K

x16) Dual-Port Static RAM. The IDT70V35/34 (IDT70V25/24) is de-

signed to be used as a stand-alone Dual-Port RAM or as a combination

MASTER/SLAVE Dual-Port RAM for 36-bit (32-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

CEpermitstheon-chipcircuitryofeachporttoenter

a very low standby power mode.

Fabricated using IDT’s CMOS high-performance technology, these

devices typically operate on only 430mW (IDT70V35/34) and 400mW

(IDT70V25/24) of power.

The IDT70V35/34 (IDT70V25/24) is packaged in a plastic 100-pin

Thin Quad Flatpack. The IDT70V25/24 is packaged in a ceramic 84-pin

PGA and 84-Pin PLCC.

Pin Configurations(1,2,3,4)

NOTES:

1.

A12 is a NC for IDT70V34.

2. All VDD pins must be connected to power supply.

3. All VSS pins must be connected to ground.

4. PN100-1 package body is approximately 14mm x 14mm x 1.4mm.

5. This package code is used to reference the package diagram.

6. This text does not indicate orientation of the actual part marking.
