The CY7C1041GE30-10ZSXI is a 4-Mbit (256K × 16) fast asynchronous CMOS SRAM with embedded ECC for single-bit error correction and an ERR output to flag correction events. It operates from 2.2 V to 3.6 V over -40°C to 85°C and supports 10 ns access time. Automatic CE power-down, 45 mA max operating current (100 MHz), and byte enables (BHE/BLE) in a 44-pin TSOP II package suit reliable memory buffering.
