CY621472GN30-45ZSXI is a 4-Mbit (256K × 16) CMOS MoBL SRAM with dual chip enable (CE1/CE2), 16-bit I/O, and byte control via BHE and BLE. It runs from 2.2 V to 3.6 V across −40°C to +85°C and supports 45 ns access. Automatic power-down draws 3.5 µA typical and 8.7 µA max, with Byte Power Down when both byte enables are disabled and HI-Z outputs when deselected. Packaged in 44-pin TSOP II.
