HIGH-SPEED

2K x 8 DUAL-PORT

STATIC RAM

Integrated Device Technology, Inc.

FEATURES:

DESCRIPTION:

• High-speed access

The IDT7132/IDT7142 are high-speed 2K x 8 Dual-Port

Static RAMs. The IDT7132 is designed to be used as a stand-

alone 8-bit Dual-Port RAM or as a “MASTER” Dual-Port RAM

together with the IDT7142 “SLAVE” Dual-Port in 16-bit-or-

more word width systems. Using the IDT MASTER/SLAVE

Dual-Port RAM approach in 16-or-more-bit memory system

applications results in full-speed, error-free operation without

the need for additional discrete logic.

— Military: 25/35/55/100ns (max.)

— Commercial: 25/35/55/100ns (max.)

— Commercial: 20ns only in PLCC for 7132

• Low-power operation

— IDT7132/42SA

Active: 550mW (typ.)

Standby: 5mW (typ.)

— IDT7132/42LA

Both devices provide two independent ports with separate

control, address, and l/O pins that permit independent, asyn-

chronousaccessforreadsorwritestoanylocationinmemory.

An automatic power down feature, controlled by CE permits

Active: 550mW (typ.)

Standby: 1mW (typ.)

• Fully asynchronous operation from either port

• MASTER IDT7132 easily expands data bus width to 16-or- the on-chip circuitry of each port to enter a very low standby

more bits using SLAVE IDT7142

power mode.

• On-chip port arbitration logic (IDT7132 only)

• BUSY output flag on IDT7132; BUSY input on IDT7142

• Battery backup operation —2V data retention

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

• Available in popular hermetic and plastic packages

• Military product compliant to MIL-STD, Class B

• Standard Military Drawing # 5962-87002

Fabricated using IDT’s CMOS high-performance technol-

ogy, these devices typically operate on only 550mW of power.

Low-power (LA) versions offer battery backup data retention

capability, with each Dual-Port typically consuming 200µW

from a 2V battery.

The IDT7132/7142 devices are packaged in a 48-pin

sidebraze or plastic DIPs, 48-pin LCCs, 52-pin PLCCs, and

• Industrial temperature range (–40°C to +85°C) is available, 48-lead flatpacks. Military grade product is manufactured in

tested to miliary electrical specifications

compliance with the latest revision of MIL-STD-883, Class B,

making it ideally suited to military temperature applications

demanding the highest level of performance and reliability.
