资 源 简 介
Typical embedded control applications place demandssuch as low power consumption, small size, low costand reduced component count onto the microcontroller.This application note implements a 24-hour digitalclock, alarm and 99 minute 59 second count downtimer, yet operates on two “AA” batteries. ThePIC16C54A is perfect for this application, due to it’ssmall size, high current I/Os with direct LED drive, lowcost, fast instruction throughput and low frequency/currentoperation.
