An automatic power down The IDT7133/7143 are high-speed 2K x 16 Dual-Port Static RAMs. feature, controlled by CE, permits the on-chip circuitry of each port to enter The IDT7133 is designed to be used as a stand-alone 16-bit Dual-Port a very low standby power mode. RAM or as a MASTER Dual-Port RAM together with the IDT7143 Fabricated using CMOS high-performance technology. Low-power SLAVE Dual-Port in 32-bit-or-more word width systems. Using the IDT (LA) versions offer battery backup data retention capability, with each port MASTER/SLAVE Dual-Port RAM approach in 32-bit-or-wider memory typically consuming 200W for a 2V battery. system applications results in full-speed, error-free operation without the The IDT7133/7143 devices have identical pinouts. Each is packed in need for additional discrete logic. a 68-pin ceramic PGA, 68-pin flatpack, 68-pin PLCC and 100-pin TQFP. Both devices provide two independent ports with separate control, Military grade product is manufactured in compliance with the latest revision of MIL-PRF-38535 QML, making it ideally suited to military temperature (1,2,3,4) applications demanding the highest level of performance and reliability.
