Microchip Technology's MCP79410T-I/SN Real-Time Clock/Calendar

The MCP79410T-I/SN is a highly integrated Real-Time Clock/Calendar (RTCC) from Microchip Technology, designed to provide precise time and date tracking, down to the second. It is an essential component for applications requiring time-stamping, calendar functions, or time-based operation in embedded systems.

This RTCC is equipped with 64 bytes of battery-backed SRAM, as well as an additional 1 Kbit of EEPROM for data storage that can be easily accessed via an I2C interface. This feature makes it perfect for applications that require data or settings to be preserved during power loss.

The device comes in an 8-pin SOIC (SN) package, making it suitable for space-constrained applications. It operates over the standard temperature range of -40°C to +85°C, ensuring reliable performance across various environments.

The MCP79410T-I/SN includes a built-in digital trimming/calibration circuit that can compensate for crystal frequency drift due to temperature or other factors, ensuring accurate timekeeping. Additionally, it features a multi-functional alarm that can be programmed to trigger on a minute, hour, day of the week, date, or month basis, as well as a power-fail timestamp that logs the time when a power failure occurs.

An integrated 64-bit unique ID is provided, which can be used for network node identification, access control, or other applications requiring a unique serial number. The device also supports battery backup with a coin cell or a supercapacitor, allowing the RTCC to continue keeping time and date while the main power is off.

The MCP79410T-I/SN is ideal for a wide range of applications, including smart energy (e.g., thermostats, power meters), home appliances, automotive electronics, and office equipment. Its rich feature set and ease of integration make it a go-to solution for developers looking to add reliable timekeeping to their projects.
