Microchip’s PIC18F14K50 is fantastic: almost anything you need in a small footprint for a low price! Absorbed in many good features of this chip, I neglected a special requirement for its flash programming when I was designing a small USB board. Unlike many other PICs, you have to drive two programming pins of this micro with 3.3v even if you are using a 5v supply. This was not a good news for me and probably many other people who want to use low cost hand made programmers. But don’t be worry! If your programmer is a PICPgm LVISP then you can program PIC18F14K50 by a applying small modification to the programmer circuit and using the latest version of PICPgm.
