About the one cpu I have designed with actually has all of that stuff. The PIC16F877 (now obsolete, I believe. Use PIC16F877A). When it comes to CPUs, a lot of your effectiveness is what you are familiar with. Don't rush to a new cpu family unless you have to, or you love suffering. When I got to it, I printed the Datasheet, got the flu, and took the Datasheet to bed for three days. It proved to be the ideal preparation. Free Programmers (Notably the Trivial Low Voltage Programmer) and software under windoze or linux are available. There is also gpsim, a reasonable linux simulator, and free Linux ICD software might also be available by now.
