Description

The IDT70T35/34L (IDT70T25/24L) is a high-speed 8/4K x 18

(8/4K x 16) Dual-Port Static RAM. The IDT70T35/34L (IDT70T25/24L)

is designed 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 200mW of power.

The IDT70T35/34L (IDT70T25/24L) is packaged in a plastic 100-pin

Thin Quad Flatpack and a 100-pin fine pitch Ball Grid Array.
