I think I saw these chips before but today I took a closer look. It’s a very interesting 16bit CPU running at 48MHz (or 12/24 when saving power). This chip (maybe) has 2.5 times the power of an AVR. I like these small DIP boards. The official site contains a lot of information. Unfortunately I haven’t found (yet) any information about the instruction set.
A binutils and gcc port for this chip would be nice. I don’t want to use a strange IDE, especially not on WinDoS.
