CY14E101Q2A-SXIT is a 1-Mbit (128K × 8) serial (SPI) nvSRAM combining SRAM with QuantumTrap nonvolatile storage per cell. It operates from 4.5 V to 5.5 V over -40°C to 85°C and supports AutoStore on power-down and RECALL on power-up, plus software STORE/RECALL via SPI. SPI mode 0/3 at 40 MHz. Max ICC1 4 mA at 40 MHz, standby 150 µA, sleep 8 µA. 8-pin SOIC with VCAP, tape-and-reel.
