CY621472G30-45ZSXA is a 4-Mbit (256K × 16) CMOS asynchronous SRAM with embedded ECC for single-bit error correction. This dual chip-enable device operates from 2.2 V to 3.6 V with 45 ns access time, and supports -40°C to +85°C Automotive-A range. It features typical 3.5 µA standby current, 1.0-V data retention, and byte write/read via BLE and BHE. Housed in a Pb-free 44-pin TSOP II package.
