3.3V Single Data Rate (SDR) Synchronous DRAM

ISSI 3.3V Single Data Rate (SDR) Synchronous DRAM provides a wide selection of SDR SDRAM with densities from 16Mbit to 512Mbit in 1Mx16, 4Mx16, and 8Mx16 organizations. Each device features a single supply voltage (3.3V +/-0.3V), standard SDRAM clock timing, LVTTL compatible inputs, programmable burst length of 1, 2, 4, 8, or full page, auto-refresh and self-refresh modes. ISSI 3.3V SDR Synchronous DRAM has a programmable CAS latency of 2 or 3. Typical applications for these devices include wireless access points, base stations, routers, network storage, energy management, industrial controls, car infotainment, and automotive telematics.
