HIGH-SPEED 3.3V

64K x18/x16

SYNCHRONOUS PIPELINED

DUAL-PORT STATIC RAM

Features:

◆

IDT70V9389/289L

◆

True Dual-Ported memory cells which allow simultaneous

access of the same memory location

High-speed clock to data access

– Commercial: 6/7.5/9/12ns (max.)

– Industrial: 9ns (max.)

Low-power operation

– IDT70V9389/289L

Active: 500mW (typ.)

Standby: 1.5mW (typ.)

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

◆

Full synchronous operation on both ports

– 3.5ns setup to clock and 0ns hold on all control, data, and

address inputs

– Data input, address, and control registers

– Fast 6.5ns clock to data out in the Pipelined output mode

– Self-timed write allows fast cycle time

– 10ns cycle time, 100MHz operation in Pipelined output mode

Separate upper-byte and lower-byte controls for

multiplexed bus and bus matching compatibility

LVTTL- compatible, single 3.3V (±0.3V) power supply

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

available for selected speeds

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

100-pin Thin Quad Flatpack (TQFP)

Green parts available, see ordering information
