The AT91SAM9G45 would need a 1.0V core power supply. The AT73C246 design can be tweaked in the factory for this or other devices. These designs are made in a 0.35u mixed signal process, which is very different from the processes used for the MCUs. I have had development boards since early this year, and it is in production for the driving customer. The part is intended for multi-market applications. -- Best Regards Ulf Samuelsson These are my own personal opinions, which may or may not be shared by my employer Atmel Nordic AB

Is that a correct number? The search function says, "Your search - AT32UC2A0 - did not match any documents" Rick

It includes ADCs, stereo audio out, ARM 926 core, available in a QFP (with reduced features from the BGA), and fairly low cost. I haven't used it, but am considering it for a product refresh in the future.
