CY62147G30-55ZSXET is a 4-Mbit (256K × 16) asynchronous CMOS SRAM with embedded ECC for single-bit error correction. The 3.0 V device operates from 2.2 V to 3.6 V over –40°C to +85°C and offers a 55 ns access time. It supports byte reads/writes via BLE/BHE, TTL-compatible I/O, and automatic power-down standby (ISB2 typ 3.5 µA, max 8.7 µA), for buffer memory in embedded systems. 44-pin TSOP II tape-and-reel.
