CY14B104LA-BA25XIT is a 4-Mbit (512K × 8) nvSRAM combining fast SRAM with QuantumTrap nonvolatile storage. It runs from 2.7 V to 3.6 V over -40°C to 85°C with 25 ns access and up to 70 mA ICC1 at 25 ns. Power-loss data protection uses AutoStore to nonvolatile cells via a 61–180 µF VCAP capacitor, with software or HSB pin STORE and software/power-up RECALL. It supports 1M STORE cycles and 20-year retention.
