Hi,

I use PIC's and 8051's.  In both cases I program in C, so the
instruction set doesn't matter too much to me.

I tend to go for PIC's for my smaller projects because the I/O
structure is much more felexible.  8051 I/O usually outputs logic
high during reset which can be a pain, as well as having weak pull
ups all the time, and this can mean more external hardware
considerations.  On chip WDT and reset also assists these small
projects, making them much more a one chip design, but the new
8051 compatible Philips 87LPC764 is worth a mention.

My 8051 designs mostly use Atmel Flash devices now, which are
exceptionally great for development.

 which are the pros and cons of selecting a PIC over a member of the 8051
