CY14B104NA-BA45XET

CY14B104NA-BA45XET is a 4-Mbit (256K × 16) automotive nvSRAM that combines fast SRAM with QuantumTrap nonvolatile storage per cell. It operates from 3.0 V to 3.6 V over –40°C to +125°C, supports 45 ns access, and delivers infinite SRAM reads and writes. Data is automatically STOREd on power-down using a 61–180 µF VCAP capacitor and RECALLed on power-up, with optional software or HSB pin control.
