Yes. They are 8051 cores so you can use the open-source compiler
SDCC. Fairly nice crossbar based IO so you can bring pretty much
any peripheral out on any pin. They're not the cheapest, though,
and their power consumption doesn't stand out quite so much these
days.<br>

You mentioned the cube is Atmel. The part number was slightly
obscured in the photo but given the Ethernet I assume it is a SAM7X,
which is ARM7. Again no problem developing for these with FOSS
tools (GCC, GDB, openocd), and again I have used them.<br>
