I use these chips interchangeably all the time. I believe the 10-bit vs 8-bit A/D modules were the only difference I had to worry about. -- Lawrence Lile Richard Prosser Sent by: pic microcontroller discussion list 11/21/02 03:36 PM Please respond to pic microcontroller discussion list To: PICLIST@MITVMA.MIT.EDU cc: Subject: Re: [PIC]: 16F873 and 16F73 I have been told that the 16F73 is a drop-in replacement for the 'C73 (except for programming). And so far I can't dispute that. So for basic features & capabilities the 16C73(B?) datasheet should be OK although things like current consumption etc may be slightly off. The main difference that effects me from the 'F873 is that the '873 has a 10bit ADC while the 'F73 has the 8bit one. There are probably other differences from the 873 also - I haven't had much to do with the 'F8xx series as yet. Richard P Hello everyone, I4d like to know wich are the differences between 16F73 and 16F873. I can not download the 16F73 pdf4s, so that4s why I ask.
