IDT70V05S/L

HIGH-SPEED 3.3V

8K x 8 DUAL-PORT

STATIC RAM

Integrated Device Technology, Inc.

• 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

FEATURES:

• True Dual-Ported memory cells which allow simulta-

neous access of the same memory location

• High-speed access

— Commercial: 25/35/55ns (max.)

• Low-power operation

• Battery backup operation—2V data retention

— IDT70V05S

•

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

Active: 350mW (typ.)

Standby: 3.5mW (typ.)

— IDT70V05L

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

TQFP

Active: 350mW (typ.)

Standby: 1mW (typ.)

DESCRIPTION:

• IDT70V05 easily expands data bus width to 16 bits or

more 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

• Busy and Interrupt Flags

The IDT70V05 is a high-speed 8K x 8 Dual-Port Static

RAM. The IDT70V05 is designed to be used as a stand-alone

Dual-Port RAM or as a combination MASTER/SLAVE Dual-

Port RAM for 16-bit-or-more word systems. Using the IDT

MASTER/SLAVE Dual-Port RAM approach in 16-bit or wider

memory system applications results in full-speed, error-free
