Title:
Run-Time Calibration of Watch Crystals
Name:
AN1155
Date:
08/25/2008
Author:
Kantesh Kudapali
Description:
In this application note, we discuss errors associated with low-cost watch crystals used in Real-Time Clock and Calendar (RTCC) applications and methods to overcome these errors. We also discuss a unique built-in calibration feature in Microchip Technology?s Real-Time Clock and Calendar circuits, which minimizes these errors during run time.
Keywords:
Run-Time, Calibration, Watch Crystals, RTCC, Real-Time Clock and Calendar
