MCP79400T-I/SN - High-Performance I2C RTC with Battery Backup: Reliable Timekeeping with Advanced Memory Features

The MCP79400T-I/SN is a highly integrated I2C-compatible real-time clock/calendar (RTCC) designed for precise timekeeping and robust data storage. Equipped with a built-in battery switchover circuit, this device ensures uninterrupted operation during power failures. It features a timestamp function to log power interruptions, along with digital trimming for enhanced accuracy. The MCP79400T-I/SN operates using a low-cost 32.768 kHz crystal or other clock sources, tracking time in both 12-hour and 24-hour formats with an AM/PM indicator. Its multifunction open-drain output can be configured as an Alarm Out or a Clock Out, supporting four selectable frequencies for versatile applications.

Designed for reliability and efficiency, this RTCC integrates both SRAM and EEPROM memory, allowing secure data storage with a unique ID section that can be unlocked and programmed by users. With its precise timekeeping, memory integration, and advanced features typically found in premium devices, the MCP79400T-I/SN is an ideal solution for embedded systems, industrial automation, and power-sensitive applications requiring consistent and accurate time tracking.

Key Features:

  • Battery Backup for Uninterrupted Operation – Integrated battery switchover circuit ensures seamless power transition during outages.
  • Accurate Timekeeping – Tracks seconds, minutes, hours, day of the week, day, month, and year in 12-hour or 24-hour formats with an AM/PM indicator.
  • Integrated Memory – Built-in SRAM and EEPROM memory with a unique ID section, providing secure and programmable data storage.
  • Power Failure Timestamp – Logs power interruptions for enhanced system reliability and monitoring.
  • Digital Trimming for Precision – Adjustable digital trimming ensures accurate clock performance over time.
  • Multifunction Output – Open-drain output configurable as Alarm Out or Clock Out, supporting four selectable frequencies.
  • I2C Compatibility – Operates over an I2C bus for seamless integration into embedded systems.
  • Low-Cost Crystal Support – Designed to work with a standard 32.768 kHz crystal or alternative clock sources.
