Datasheet Summary
Powered by GS/AI

The MCP79410/MCP79411/MCP79412 series is a battery-backed I²C real-time clock/calendar designed for industrial applications with an operating temperature range of -40°C to +85°C. It features a comprehensive timekeeping capability, tracking hours, minutes, seconds, day of the week, day, month, and year, with leap year compensation up to the year 2399. The device supports both 12-hour and 24-hour clock formats and is optimized for use with 32.768 kHz crystals. This series includes dual programmable alarms and a versatile output pin that can be configured for clock output, alarm output, or general-purpose output. The MCP7941X also logs power-fail events, ensuring accurate timekeeping and SRAM content retention during power loss. The device operates within a voltage range of 1.8V to 5.5V, with a low typical timekeeping current of 1.2 µA at 3.3V when powered from VCC, and 925 nA at 3.0V when powered from the backup battery. It includes 64 bytes of battery-backed SRAM and 1 Kbit of EEPROM memory, with features such as software write protection and a robust unlock sequence for critical data storage. The MCP7941X series is available in multiple package types, including 8-lead SOIC, MSOP, TSSOP, and 2x3 TDFN, making it suitable for various design requirements.
