Hello,
For a small project, which should be very cost oriented, I need a simple microcontroller whos main task should be implementing SMI serial interface. This means it should heve at least 2 I/O pins which are TRI-STATE enabled. It should have a very small on-chip RAM for data and small on-chip memory (can be even OTP) for the code.
I would also want it to have a nice development environment (actualy, ANSI-C compiler should be ok).
Do you know of a good enough microcontroller (its cost and how do I get it)? Do you think I should go for those 8-bit ones for their simplicity (cheap chip but expensive tools) or for the 8051-compatible for their well spread and tools support?
