IDT70V05S/L

HIGH-SPEED 3.3V

8K x 8 DUAL-PORT

STATIC RAM

Features

◆

using the Master/Slave select when cascading more than

one device

M/S = VIH for BUSY output flag on Master

M/S = VIL for BUSY input on Slave

Interrupt Flag

On-chip port arbitration logic

Full on-chip hardware support of semaphore signaling

between ports

Fully asynchronous operation from either port

TTL-compatible, single 3.3V (±0.3V) power supply

Available in 68-pin PGA and PLCC, and a 64-pin TQFP

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

for selected speeds

True Dual-Ported memory cells which allow simultaneous

reads of the same memory location

High-speed access

◆
