CY14B104NA-ZS45XE is a 4-Mbit (256K × 16) automotive parallel nvSRAM that combines fast SRAM with QuantumTrap nonvolatile storage. It operates from 3.0 V to 3.6 V over –40°C to +125°C, supports 45 ns access, and performs hands-off AutoStore on power-down using a 61 µF to 180 µF VCAP capacitor. It is available in a 44-pin TSOP II package; STORE/RECALL can be initiated by software or the HSB pin.
