An increasing number of applications that involve time
measurement are requiring a Real-Time Clock device.
The MCP79410 is a feature-rich RTCC that incorpo-
rates EEPROM, SRAM, unique ID and time-stamp.
This application note describes how to compensate the
parabolic thermal drift of some crystals in RTCC-based
projects, using the Calibration register. AN1413
