I am looking for a microcontroller that will serve as the main processing unit for a range of 4-20mA instrument sensors. It must have at least 90% of the following spec:
2 x 12-bit analog inputs
2 x 12-bit analog outputs
4 x digital inputs
12 x digital outputs
At least one RS232 port
Preferably ethernet ability
Driver for a graphical LCD display 128 x 64
Keypad input
I have found a number of single board computer manufacturers but none that offer all of this capability on one board. The problem tends to be lack of analog I/O.
Has anyone come across a microcontroller/SBC with these capabilities? If so could you tell me who manufactures them?
