CY14B108M-ZSP45XI is an 8-Mbit nvSRAM (512 K × 16) with integrated real-time clock, combining SRAM with QuantumTrap nonvolatile storage. It supports 45 ns access and 2.7 V to 3.6 V operation over -40°C to 85°C in a 54-pin TSOPII. Hands-off AutoStore on power-down and RECALL on power-up protect data without firmware. It specifies 20-year data retention and 1M STORE cycles, plus alarm and watchdog timer.
