CY14B104NA-BA45XE

CY14B104NA-BA45XE is a 4-Mbit (256K × 16) automotive nvSRAM that combines fast SRAM with QuantumTrap nonvolatile cells. It operates from 3.0 V to 3.6 V across −40°C to +125°C with 45 ns access time. Data is automatically stored on power-down via a 61 µF to 180 µF VCAP capacitor and recalled on power-up; it supports 100K nonvolatile STORE cycles and 1-year data retention for configuration data.
