HIGH-SPEED 2.5V

256/128/64K x 36

IDT70T3519/99/89S

SYNCHRONOUS

DUAL-PORT STATIC RAM

WITH 3.3V OR 2.5V INTERFACE

Features:

– Data input, address, byte enable and control registers

– Self-timedwriteallowsfastcycletime

Separate byte controls for multiplexed bus and bus

matching compatibility

Dual Cycle Deselect (DCD) for Pipelined Output Mode

2.5V (±100mV) 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 256-pin Ball Grid Array (BGA), a 208-pin

Plastic Quad Flatpack (PQFP) and 208-pin fine pitch Ball

Grid Array (fpBGA)

Supports JTAG features compliant with IEEE 1149.1

Due to limited pin count JTAG is not supported on the 208-

pin PQFP package

◆

True Dual-Port memory cells which allow simultaneous

access of the same memory location

High-speed data access

◆

– Commercial: 3.4 (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

Interrupt and Collision Detection Flags

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 @ 200MHz

NOTES:

1. Address A17 is a NC for the IDT70T3599. Also, Addresses A17 and A16 are NC's for the IDT70T3589.

2. The sleep mode pin shuts off all dynamic inputs, except JTAG inputs, when asserted. All static inputs, i.e., PL/FTx and OPTx

APRIL 2004

and the sleep mode pins themselves (ZZx) are not affected during sleep mode.
