70V3379S

HIGH-SPEED 3.3V 32K x 18

SYNCHRONOUS PIPELINED

DUAL-PORT STATIC RAM

WITH 3.3V OR 2.5V INTERFACE

Features:

– Data input, address, byte enable and control registers

– Self-timedwriteallowsfastcycletime

Separate byte controls for multiplexed bus and bus

matching compatibility

LVTTL- compatible, single 3.3V (±150mV) power supply for

core

LVTTL- compatible, selectable 3.3V (±150mV)/2.5V (±125mV)

power supply for I/Os and control signals on each port

Industrial temperature range (-40°C to +85°C) is

available for selected speeds

Available in a 128-pin Thin Quad Plastic Flatpack (TQFP)

and 208-pin fine pitch Ball Grid Array, and 256-pin

Ball Grid Array

◆

True Dual-Port memory cells which allow simultaneous

access of the same memory location

High-speed clock to data access

◆

– Commercial:4.2/5/6ns(max.)

– Industrial: 5ns (max)

Pipelined output mode

◆

Counter enable and reset features

Dual chip enables allow for depth expansion without

additional logic
