Yes to all those questions. I use the 8052 microcontroller which has been
around for ages and is available in lots of different versions. There are
plenty of free and evaluation tools including all sorts of emulators some
of which will simulate external circuits too. A google search will bring up
lots of sites. You could do worse than start at www.8052.com which has
tutorials and many links.
