HIGH-SPEED

IDT7007S/L

32K x 8 DUAL-PORT

STATIC RAM

Features

◆

using the Master/Slave select when cascading more than

one device

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

M/S = L for BUSY input on Slave

Interrupt Flag

On-chip port arbitration logic

True Dual-Ported memory cells which allow simultaneous

reads of the same memory location

High-speed access

◆

– Military:25/35/55ns(max.)

◆

– Industrial:20/25/35/55ns(max.)

– Commercial:15/20/25/35/55ns(max.)

Low-power operation

◆

Full on-chip hardware support of semaphore signaling

between ports

– IDT7007S

◆

Fully asynchronous operation from either port

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

Available in 68-pin PGA and PLCC and a 80-pin TQFP

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

for selected speeds

Active:850mW(typ.)

Standby: 5mW (typ.)

– IDT7007L

Active:850mW(typ.)

Standby: 1mW (typ.)

IDT7007 easily expands data bus width to 16 bits or more
