Hello all, I often have designs that need rs-485 with some relatively 
simple microcontroller code, and it is always been a two-chip solution: 
75176 (or equivalent with improvements) and a PIC of some sort.

Does anyone know of a microcontroller with a built-in RS-485 
transceiver?  Ideally it would have a UART (pretty much a necessity, but 
not absolutely required), 16 pins or less, and a decent C compiler 
available from the vendor or 3rd party that doesn't cost a kilobuck. 
Freeware versions limited to say 4K codespace are acceptable.

I haven't done an exhaustive search but I've never seen rs-485 built-in 
to a micro, which is a bit surprising in a way.

Anyway, love to hear anyone's experiences.
Thanks-
Jesse
