CY14MB064Q2A-SXQ

CY14MB064Q2A-SXQ is a 64-Kbit (8K × 8) SPI nvSRAM that combines SRAM with QuantumTrap nonvolatile storage for automatic data STORE on power-down and RECALL on power-up, with infinite SRAM read/write cycles. It operates from 2.7 V to 3.6 V over -40°C to +105°C, supports 40 MHz SPI (modes 0 and 3), and offers 250 µA max standby and 20 µA max sleep current plus write/block protection.
