More Hobby PIC18 Devices

The best hobby chips are: (spaces added in part numbers for readability)

  • PIC 18 F 26/46 20 – Very robust, but a bit more expensive ($5.50), 100 K flash write cycles (the two below only have 10 K flash write cycles)
  • PIC 18 F 26/46 K 20 – Low power
  • PIC 18 F 26/46 J 50 – Low cost ($3.30), 2 – 3.3 V, 5.5 V tolerant digital inputs, USB, peripheral pin select, RTCC
  • PIC 18 F 2550 – USB

The 18F26J50 definitely seems cool. Note that the 46 models (as opposed to the 26 models) have higher pin counts and therefore, more ADC channels. Both come in DIP packages – very hobby friendly. The only trouble with the 18F26J50 is that it has a maximum voltage of 3.3 V.
