IDT70V35/34S/L (IDT70V25/24S/L)

High-Speed 3.3V 8/4K x 18 (8/4K x 16) Dual-Port Static RAM

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

Industrial and Commercial Temperature Ranges

feature controlled by CE permits the on-chip circuitry of each port to enter

a very low standby power mode.

Fabricated using IDTâs 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.
