MCP794XX Microchip Real-Time Clock/Calendar ICs

Microchip Technology MCP794XX Microchip Real-Time Clock/Calendar (RTCC) ICs offer low-cost system timekeeping solutions with 64 bytes of SRAM and up to 2 Kbits of EEPROM, including a user-lockable section of EEPROM that can be factory-programmed with a MAC address. Features include digital trimming, power-fail time stamp, and battery-switchover. MCP794XX RTCCs are ideally suited for smart energy, home appliance, automotive, and consumer electronic applications.
