Hello Srigopal,

s>>I have previously used a 8051 microcontroller to perform most if not all of my processing needs. I have recently been introduced to the Microchip PIC microcontrollers. I was wondering if it is possible to replace the entire 8051 chip and have the PIC do the same exact things.<<

Definitely... the 80C51 microprocessors are what I used to program. Personally the PICS are a heck of a lot cheaper, nicer to work with, and IMO just as solid or even more.

Since the pin count is different than, and the VSS and VCC are different, I seriously doubt if there is a direct "PLUG-IN" chip that will match up.

I think I still have a dozen or so 750's and 752's , programmer, and emulator I don't know what I am going to do with <g>
