CY14B108K-ZS45XI is an 8-Mbit (1024 K × 8) nvSRAM with integrated real-time clock, combining SRAM with QuantumTrap nonvolatile storage. It operates from 2.7 V to 3.6 V over -40°C to 85°C with 45 ns access time in a 44-pin TSOPII package. Data retention is 20 years with 1 million STORE cycles. AutoStore on power-down plus software or HSB pin STORE/RECALL preserve data and timekeeping.
