HIGH-SPEED

IDT7005S/L

8K x 8 DUAL-PORT

STATIC RAM

Features

◆

True Dual-Ported memory cells which allow simultaneous

reads of the same memory location

High-speed access

M/S = H for BUSY output flag on Master,

M/S = L for BUSY input on Slave

Interrupt Flag

◆

– Military:20/25/35/55/70ns(max.)

– Industrial:20/35/55ns(max.)

– Commercial:15/17/20/25/35/55ns(max.)

Low-power operation

On-chip port arbitration logic

Full on-chip hardware support of semaphore signaling

between ports

◆

Fully asynchronous operation from either port

Devices are capable of withstanding greater than 2001V

electrostatic discharge

– IDT7005S

Active:750mW(typ.)

◆

Standby: 5mW (typ.)

Battery backup operation—2V data retention

TTL-compatible, single 5V (±10%) power supply

Available in 68-pin PGA, PLCC and a 64-pin thin quad

flatpack

– IDT7005L

Active:700mW(typ.)

Standby: 1mW (typ.)

◆

IDT7005 easily expands data bus width to 16 bits or more

using the Master/Slave select when cascading more than

one device

Industrial temperature range (-40°C to +85°C) is available for

selectedspeeds

Green parts available, see ordering information
