I have been looking at the Dallas/Maxim DS80C400 uC as an alternative to the rabbit processor which my company currently use.

Our current rabbit application uses
TCP/IP,
CAN (external SPI controller),
1-Wire (via DS2480, on a serial post),
Serial Flash (on SPI, for file storage) and
3 External serial ports (multiplexed via a single serial port).

This device looks like it may reduce the component count considerably, and also the software overhead for driving CAN and 1-Wire coms, thus making the product more viable / profitable.

I would very much apreciate if anybody has used this part with reference to the above, what is your opinion on using the device?

Rob.
