HIGH-SPEED 2.5V

512/256/128K X 18

SYNCHRONOUS

PRELIMINARY

IDT70T3339/19/99S

DUAL-PORT STATIC RAM

WITH 3.3V OR 2.5V INTERFACE

– Data input, address, byte enable and control registers

Features:

◆

– 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 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

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, 200MHzoperation(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 A18 is a NC for the IDT70T3319. Also, Addresses A18 and A17 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

NOVEMBER 2003

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