CY14B101Q2A-SXI

Active and preferred

CY14B101Q2A-SXI is a 1-Mbit (128K × 8) SPI nvSRAM combining SRAM with QuantumTrap nonvolatile storage to retain data through power loss. It operates from 2.7 V to 3.6 V over -40°C to 85°C, supports AutoStore on power-down, and allows software STORE/RECALL over SPI. The device offers 40 MHz SPI with mode 0/3, 150 µA standby, hardware WP write protection, and an 8-byte serial number.
