Microchip MCP79410T-I/MNY Real-Time Clock/Calendar with EEPROM

The MCP79410T-I/MNY is a highly integrated real-time clock/calendar (RTCC) with additional memory features, manufactured by the renowned semiconductor company, Microchip Technology. Designed to provide precise time and date tracking, this component is ideal for a wide range of applications in consumer electronics, industrial systems, and network infrastructure that require accurate timekeeping.

This RTCC is equipped with a built-in 64 x 8-bit EEPROM, which can be used for data storage purposes. The non-volatile memory ensures that data is retained even when the main power is lost, thanks to the onboard battery backup capability. The MCP79410T-I/MNY operates over a standard voltage range of 1.8V to 5.5V, making it versatile for various design specifications.

One of the key features of this product is its I2C communication interface, which allows for easy integration into most microcontroller-based systems. The device also includes a unique ID with a pre-programmed MAC address, simplifying network node identification and reducing the need for external components.

The MCP79410T-I/MNY provides a multitude of timekeeping features, such as seconds, minutes, hours, day, date, month, and year information. It also accommodates leap year correction and offers selectable frequency outputs. The integrated alarms can be programmed to trigger on a minute, hour, day, or date basis, providing flexibility for various time-based events.

Additional features include a digital trimming capability that allows fine-tuning of the oscillator for precise timekeeping, a power-fail time-stamp that logs the time when power is lost, and an automatic switchover to battery backup. The compact design of the MCP79410T-I/MNY, available in a TSSOP-8 package, ensures minimal footprint on the PCB, making it an excellent choice for space-constrained applications.

Overall, the MCP79410T-I/MNY from Microchip Technology is a feature-rich RTCC that provides robust timekeeping solutions with the added benefit of integrated memory, making it a solid choice for designers looking to enhance their systems with reliable time and data management capabilities.
