IDT7130SA/LA and IDT7140SA/LA
High-Speed 1K x 8 Dual-Port Static SRAM
Military, Industrial and Commercial Temperature Ranges
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.
