I've never used them myself but have always been fascinated by them. The application notes make it sound fairly straightforward to use. Maybe someone that has used them can chime in with their experience with them. I believe the older rfPIC12C509 windowed devices are DIP. They were about $10 a pop a few months ago. The newer flash devices are SMD only.

I suppose I could use rfPICs for my project, are they hard to use? I wasn't sure if they made thru hole versions of the chips so I never bothered ordering samples. I refuse to use SMT parts for prototyping, too much pain in the butt. With these rfPICs, is it just a matter of hooking up an antenna or is there all kinds of external circuitry required? In any case, I will go to microchip.com and read over some datasheets. Thanks for the info guys... Peace MJ Brush -- http://www.piclist.com#nomail Going offline?
