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.

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.
