HIGH-SPEED 64K x 9

IDT709189L

SYNCHRONOUS PIPELINED

DUAL-PORT STATIC RAM

Features

◆

True Dual-Ported memory cells which allow simultaneous

access of the same memory location

High-speed clock to data access

– Commercial: 7.5/9/12ns (max.)

Low-power operation

Full synchronous operation on both ports

– 4ns setup to clock and 0ns hold on all control, data, and

address inputs

◆

– Data input, address, and control registers

– Fast 7.5ns clock to data out in the Pipelined output mode

– Self-timed write allows fast cycle time

– IDT709189L

Active: 1.2W (typ.)

Standby: 2.5mW (typ.)

– 12ns cycle time, 83MHz operation in Pipelined output mode

TTL- compatible, single 5V (±10%) power supply

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

available for selected speeds

◆

Flow-Through or Pipelined output mode on either Port via

the FT/PIPE pins

Counter enable and reset features

Dual chip enables allow for depth expansion without

additional logic

◆

Available in a 100-pin Thin Quad Flatpack (TQFP) package
