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

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.
