Re: AVR question
well, try 90s8515 (it comes with DIP package too). interface to external memory, UART. the 2 MPUs could communicate via UART: 1 MPU is connected to keyboard and communicates with the other MPU via UART. if you want to reserve UART for an external rs232, then you can use...
Re: AVR question
it depends on the detailed system... why you do not whant to use atmega? is it too expensive? of course, sometimes it's better to use 2 MPUs, 1 deals with basic tasks the other is for some peripherial tasks, but again, it's better to discuss a circuit in details, not just a...
hello, you can try MSCOMM module, it is well described in MSDN or
use standard windows APIs for controlling a serial port

Re: AVR question
well, it depends on a certain system you are going to develop of course. but i suppose that atmega128 could suit your needs, it has six (8pin) ports including multiplex data and address ports, and port g (alternative, i.e. instead of ALE, WR, RD, etc).

Re: C or Matlab?
Matlab allows you to check your ideas faster and convert the result to C/C++ code, on the other hand, if you design takes resources, then you can write it in C, after verification in Matlab, for example
