IDT7130SA/LA and IDT7140SA/LA

High-Speed 1K x 8 Dual-Port Static SRAM

Description

The IDT7130/IDT7140 are high-speed 1K x 8 Dual-Port Static

RAMs. The IDT7130 is designed to be used as a stand-alone 8-bit

Dual-Port RAM or as a "MASTER" Dual-Port RAM together with the

IDT7140 "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.

Both devices provide two independent ports with separate con-

trol, address, and I/O pins that permit independent asynchronous

access for reads or writes to any location in memory. An automatic

power down feature, controlled by CE, permits the on chip circuitry

Military, Industrial and Commercial Temperature Ranges

of each port to enter a very low standby power mode.

Fabricated using CMOS high-performance technology, these de-

vices 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 IDT7130/IDT7140 devices are packaged in 48-pin sidebraze

or plastic DIPs, LCCs, flatpacks, 52-pin PLCC, and 64-pin TQFP

and STQFP. Military grade products are manufactured in compli-

ance with the latest revision of MIL-PRF-38535 QML, making it

ideally suited to military temperature applications demanding the

highest level of performance and reliability.
