ISSI IS62WVS Serial SRAMs
ISSI IS62WVS Serial SRAMs are fabricated using high-performance CMOS technology to provide a 4µA standby current. These SRAMs are 512K, 1M, or 2M bit-serial static RAMs organized as 64K, 128K, or 256K bytes respectively by 8 bits. The I62WVS serial SRAMs offer a 20MHz clock rate, Serial Peripheral Interface (SPI) compatible bus interface, and support unlimited reads and writes to the memory array. The additional interfaces supported are Serial Dual Interface (SDI) and Serial Quad Interface (SQI) for the faster data rate requirements. These SRAMs operate within the -40°C to +85°C temperature range and are available in a lead-free 8-pin SOIC package. Typical applications include industrial IoT, advanced driver assistance systems, and the medical industry.
