CY7C1049G-10VXI is a 4-Mbit (512K × 8) asynchronous CMOS SRAM with embedded ECC for single-bit error correction. The -10 grade supports 10 ns access time and operates from 4.5 V to 5.5 V over the industrial -40°C to +85°C range. It uses CE/WE/OE control, supports 1.0 V data retention, and draws 38 mA typ operating current (45 mA max at 100 MHz). It is offered in a Pb-free 36-pin molded SOJ (V) package.
