PIC16F628 Digital Clock Timer circuit and explanation

Posted on Feb 6, 2014

This clock timer uses a PIC16F628 microcontroller to display 3 and 1/2 digit time and control an external load. It can be programmed to time from 1 to 59 minutes. The clock includes a calendar with leap year and optional daylight savings adjustments. The timer output can be set from 1 to 59 minutes and manually switched on and off. The clock also

has a correction feature that allows an additional second to be added every so many hours to compensate for a slightly slow running oscillator. The oscillator uses a common 32. 768 KHz watch crystal and the frequency can be adjusted slightly with the 24pF capacitor on the right side of the crystal.
