CY14B104M-ZSP45XIT

Active and preferred

CY14B104M-ZSP45XIT is a 4-Mbit nvSRAM (256 K × 16) 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 and supports AutoStore on power-down plus software or HSB pin STORE/RECALL. Data retention is 20 years with 1,000 K STORE cycles, and RTC backup runs from 1.8 V to 3.6 V. 45 ns access, 54-pin TSOP II.
