Features:

◆

HIGH-SPEED 2.5V

512/256/128K X 18

IDT70T3339/19/99S

SYNCHRONOUS

DUAL-PORT STATIC RAM

WITH 3.3V OR 2.5V INTERFACE

◆

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

◆

– Data input, address, byte enable and control registers

– Self-timed write allows fast cycle time

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 144-pin Thin

Quad Flatpack (TQFP) and 208-pin fine pitch Ball Grid Array

(fpBGA)

Supports JTAG features compliant with IEEE 1149.1

Due to limited pin count JTAG, Collision Detection and

Interrupt are not supported on the 144-pin TQFP package

NOTES:

1. Address A

is a NC for the IDT70T3319. Also, Addresses A

and A

are NC's for the IDT70T3399.

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

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