CY14B116N-ZSP25XIT is a 16-Mbit nvSRAM organized as 1024K × 16 with QuantumTrap nonvolatile storage. It operates from 2.7 V to 3.6 V over -40°C to 85°C and delivers 25 ns access in a 54-pin TSOP II package (tape-and-reel). Data is automatically stored on power-down using an external 19.8 µF to 82.0 µF VCAP capacitor and recalled on power-up, with 1,000,000 STORE cycles and 20-year retention.
