HIGH-SPEED 3.3V 512K x 18

SYNCHRONOUS

BANK-SWITCHABLE

IDT70V7339S

DUAL-PORT STATIC RAM

WITH 3.3V OR 2.5V INTERFACE

Features:

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

address inputs @ 200MHz

◆

512K x 18 Synchronous Bank-Switchable Dual-ported

– Data input, address, byte enable and control registers

– Self-timedwriteallowsfastcycletime

Separate byte controls for multiplexed bus and bus

matching 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 144-pin Thin Quad Flatpack (TQFP),

208-pin fine pitch Ball Grid Array (fpBGA), and 256-pin Ball

GridArray(BGA)

Supports JTAG features compliant with IEEE 1149.1

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

144-pin TQFP package.

SRAM Architecture

– 64 independent 8K x 18 banks

– 9 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, 200MHzoperation(14Gbps bandwidth)

– Fast 3.4ns clock to data out

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 functional description on page 19
