CY14B256LA-ZS25XIT

CY14B256LA-ZS25XIT is a 256-Kbit (32 K × 8) parallel nvSRAM combining fast SRAM with QuantumTrap nonvolatile storage. It operates from 2.7 V to 3.6 V over -40°C to 85°C with 25 ns access. Data is saved automatically on power-down using a 61–180 µF VCAP capacitor, or by HSB pin or software command. Rated for 1 million STORE cycles and 20-year retention in a 44-pin TSOP II package.
