HIGH-SPEED 3.3V

256/128K x 18

IDT70V3319/99S

SYNCHRONOUS

DUAL-PORT STATIC RAM

WITH 3.3V OR 2.5V INTERFACE

Features:

◆

– Data input, address, byte enable and control registers

True Dual-Port memory cells which allow simultaneous

access of the same memory location

High-speed data access

– Self-timedwriteallowsfastcycletime

Separate byte controls for multiplexed bus and bus

matching compatibility

Dual Cycle Deselect (DCD) for Pipelined Output mode

LVTTL- compatible, single 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 133MHz.

Available in a 128-pin Thin Quad Flatpack, 208-pin fine

pitch Ball Grid Array, and 256-pin Ball

GridArray

Supports JTAG features compliant to IEEE 1149.1

– Due to limited pin count, JTAG is not supported on the

128-pin TQFP package.

◆

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

– Industrial: 4.2ns (133MHz) (max.)

Selectable Pipelined or Flow-Through output mode

– Due to limited pin count PL/FToption is not supported

on the 128-pin TQFP package. Device is pipelined

outputs only on each port.

Counter enable and repeat features

Dual chip enables allow for depth expansion without

additional logic

◆

Full synchronous operation on both ports

– 6ns cycle time, 166MHz operation (6Gbps bandwidth)

– Fast 3.6ns clock to data out

◆

– 1.7ns setup to clock and 0.5ns hold on all control, data, and

address inputs @ 166MHz
