CY14B064PA-SFXI

Active and preferred

CY14B064PA-SFXI is a 64-Kbit (8 K × 8) SPI nvSRAM with integrated real-time clock, combining SRAM with QuantumTrap nonvolatile storage. It supports 40 MHz SPI plus 104 MHz fast-read instructions, AutoStore on power-down and RECALL on power-up, and software/hardware STORE via HSB. 20-year retention and 1M STORE cycles. Operates from 2.7 V to 3.6 V over -40°C to 85°C in a 16-pin SOIC.
