FEBRUARY 2013 DSC-2720/14 IDT7134SA/LA High-Speed 4K x 8 Dual-Port Static SRAM Military, Industrial and Commercial Temperature Ranges The IDT7134 is a high-speed 4K x 8 Dual-Port Static RAM designed to be used in systems where on-chip hardware port arbitration is not needed. This part lends itself to those systems which cannot tolerate wait states or are designed to be able to externally arbitrate or withstand contention when both sides simultaneously access the same Dual-Port RAM location. The IDT7134 provides two independent ports with separate control, address, and I/O pins that permit independent, asynchronous access for reads or writes to any location in memory. It is the user’s responsibility to ensure data integrity when simultaneously accessing the same memory location from both ports. 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 DualPorts typically operate on only 700mW of power. Low-power LA versions offer battery backup data retention capability, with each port typically consuming 200µW from a 2V battery. The IDT7134 is packaged on either a sidebraze or plastic 48-pin DIP, 48-pin LCC, 52-pin PLCC and 48-pin Flatpack. Military grade product is manufactured in compliance with MIL-PRF-38535 QML, making it ideally suited to military temperature applications demanding the highest level of performance and reliability.
