Description

The IDT70V16/5 is a high-speed 16/8K x 9 Dual-Port Static RAM.

The IDT70V16/5 is designed to be used as stand-alone Dual-Port RAMs

or as a combination MASTER/SLAVE Dual-Port RAM for 18-bit-or-more

wider systems. Using the IDT MASTER/SLAVE Dual-Port RAM ap-

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

a very low standby power mode.

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

devices typically operate on only 430mW of power.

The IDT70V16/5 is packaged in a 64-pin PLCC (Plastic Leaded

Chip Carriers) and an 80-pinTQFP (Thin Quad Flatpack).
