HIGH-SPEED 3.3V 256K x 18

SYNCHRONOUS

BANK-SWITCHABLE

DUAL-PORT STATIC RAM

WITH 3.3V OR 2.5V INTERFACE

Features:

◆

IDT70V7319S

◆

256K x 18 Synchronous Bank-Switchable Dual-ported SRAM

Architecture

–

64 independent 4K x 18 banks

– 4 megabits of memory on chip

Bank access controlled via bank address pins

High-speed data access

– Commercial: 3.4ns (200MHz)/3.6ns (166MHz)/

4.2ns (133MHz) (max.)

– Industrial: 3.6ns (166MHz)/4.2ns (133MHz) (max.)

Selectable Pipelined or Flow-Through output mode

Counter enable and repeat features

Dual chip enables allow for depth expansion without

additional logic

Full synchronous operation on both ports

– 5ns cycle time, 200MHz operation (14Gbps bandwidth)

– Fast 3.4ns clock to data out

◆

– 1.5ns setup to clock and 0.5ns hold on all control, data, and

address inputs @ 200MH

– Data input, address, byte enable and control registers

– Self-timed write allows fast cycle time

Separate byte controls for multiplexed bus and bus match-

ing compatibility

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

for core

LVTTL compatible, selectable 3.3V (±150mV) or 2.5V

(±100mV) power supply for I/Os and control signals on each

port

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

available at 166MHz and 133MHz

Available in a 208-pin fine pitch Ball Grid Array (fpBGA) and

256-pin Ball Grid Array (BGA)

Supports JTAG features compliant with IEEE 1149.1

Green parts available, see ordering information

NOTE:

1. The Bank-Switchable dual-port uses a true SRAM core

instead of the traditional dual-port SRAM core. As a result, it

has unique operating characteristics. Please refer to the
