MARCH 2018 1 DSC 2738/19 2018 Integrated Device Technology, Inc.IDT7005S/L High-Speed 8K x 8 Dual-Port Static RAM Military, Industrial and Commercial Temperature Ranges Description The IDT7005 is a high-speed 8K x 8 Dual-Port Static RAM. The IDT7005 is designed to be used as a stand-alone 64K-bit Dual-Port RAM Fabricated using CMOS high-performance technology, these de- or as a combination MASTER/SLAVE Dual-Port RAM for 16-bit-or- vices typically operate on only 750mW of power. Low-power (L) versions more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM offer battery backup data retention capability with typical power consump- tion of 500W from a 2V battery. approach in 16-bit or wider memory system applications results in full- The IDT7005 is packaged in a ceramic 68-pin PGA, 68-pin PLCC speed, error-free operation without the need for additional discrete logic. This device provides two independent ports with separate control, and a 64-pin thin quad flatpack, (TQFP). Military grade product is address, and I/O pins that permit independent, asynchronous access for manufactured in compliance with MIL-PRF-38535 QML making it ideally suited to military temperature applications demanding the highest level of reads or writes to any location in memory. An automatic power down performance and reliability. feature controlled by CE permits the on-chip circuitry of each port to enter a very low standby power mode.
