HIGH-SPEED 8/4K x 18

SYNCHRONOUS PIPELINED

DUAL-PORT STATIC RAM

IDT709359/49L

Features

◆

True Dual-Ported memory cells which allow simultaneous

access of the same memory location

High-speed clock to data access

– Commercial:6.5/7.5/9ns(max.)

– Industrial: 7.5ns (max.)

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

◆

Low-power operation

– IDT709359/49L

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

Separate upper-byte and lower-byte controls for

multiplexed bus and bus matching compatibility

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

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

available for 83 MHz

◆

Active:925mW(typ.)

Standby: 2.5mW (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

◆

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

Green parts available, see ordering informaiton
