Description

The Microchip MCP79401-I/MS is a highly integrated Real-Time Clock/Calendar (RTCC) optimized for time tracking and data logging solutions. This compact, feature-rich component is housed in an 8-pin MSOP (Micro Small Outline Package) and is designed to maintain accurate timekeeping with minimal power consumption, making it ideal for a wide range of applications including smart energy, industrial, consumer electronics, and networking.

Key Features:

  • Accurate Timekeeping: The MCP79401-I/MS includes a built-in digital trimming circuit that compensates for crystal frequency drift, ensuring high accuracy in timekeeping.
  • Battery Backup: With a battery backup input pin, the device maintains timekeeping in the event of a main power failure, making it reliable for critical applications that require continuous time tracking.
  • EERAM: An integrated Electrically Erasable RAM (EERAM) provides reliable data storage that can be used to store important system data that needs to be preserved during power loss.
  • Programmable Clock Output: The device features a programmable clock output that can be used for clock generation and can be set to a variety of frequencies, providing flexibility for system design.
  • Alarm Function: A versatile alarm function allows users to set alarms on a variety of time scales, from seconds to days, making it adaptable for different scheduling needs.
  • I2C Interface: The MCP79401-I/MS communicates via the industry-standard I2C bus, allowing for easy integration into most microcontroller-based systems.
  • Power Management: Low-power consumption is a hallmark of this device, with a wide voltage range and low current draw in battery-backup mode.
  • Unique ID: The chip provides a factory-programmed, unique MAC address, which can be used for networked device identification, eliminating the need for external EEPROM for MAC storage.

This RTCC is a perfect solution for systems that require an accurate time base for various functions, such as time-stamping, event scheduling, and data logging. Its small footprint and comprehensive set of features make the Microchip MCP79401-I/MS a versatile choice for designers looking to enhance their applications with reliable timekeeping capabilities.
