Real time clock

[gadelhas]

I am using a PIC18F2450 and need real time clock to schedule events, is this possible in the PIC? if not, is there a 28pin PIC with PIC18F2450 specs and real time clock? Is there an external chip that I could interface with?

Hi;
There are various external RTC Chips. One that is very easy to interface and there are several exemples in this forum is the DS1307. There are some PICs with RTC, go to Microchip site and use the chip selector.
