Could anybody advise me which is better solution:

 

1)       To put battery on board and put additional circuit for putting PIC
into sleep mode after it detects power failure

 

Or

 

2)       Design some sort of circuit that would store data in PIC's EEPROM
after power failure. I assume you would have to put some capacitor to store
enough power for PIC to save data to EEPROM. Am I right?

 

 

Thank you,

Sam
