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 Fabricated using CMOS high-performance technology, these de- vices typically operate on only 550mW of power. Low-power (LA) Dual-Port RAM or as aMASTE Dual-Port RAM together with the versions offer battery backup data retention capability, with each Dual- IDT7140SLAV Dual-Port in 16-bit-or-more word width systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 16-or- Port typically consuming 200W from a 2V battery. The IDT7130/IDT7140 devices are packaged in 48-pin sidebraze more-bit memory system applications results in full-speed, error- or plastic DIPs, LCCs, flatpacks, 52-pin PLCC, and 64-pin TQFP free operation without the need for additional discrete logic. Both devices provide two independent ports with separate con- and STQFP. Military grade products are manufactured in compli- ance with the latest revision of MIL-PRF-38535 QML, making it trol, address, and I/O pins that permit independent asynchronous ideally suited to military temperature applications demanding the access for reads or writes to any location in memory. An automatic power down feature, controlled by CE, permits the on chip circuitry highest level of performance and reliability.
