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 MAS-

TER/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 sepa-

rate control, 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 of each port to enter a very

low standby power mode.

Fabricated using IDT's CMOS high-performance tech-

nology, these devices typically operate on only 550mW of

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

retention capability, with each Dual-Port typically consum-

ing 200µW from a 2V battery.

The IDT7130/IDT7140 devices are packaged in 48-pin

sidebraze or plastic DIPs, LCCs, or flatpacks, 52-pin PLCC,

and 64-pin TQFP and STQFP. Military grade product is

manufactured in compliance with the latest revision of MIL-

STD-883, Class B, making it ideally suited to military tem-

perature applications demanding the highest level of per-

formance and reliability.
