However I got some very high-powered HP supplies with several of these microcontrollers that I wish to re-purpose (the supplies, I mean). Does anybody have tips on how to program these chips with simple tools? Given that I...

    Fake 24/32-bit ADC, is that possible??

    24bit would do, actually i would be quite happy with 22 and I frankly don't really understand how anyone finds the voltage references to work with much more. But, the price for the 32 bit version just seemed bizarre to me. Btw the chips don't look de-soldered at all - if they send what they...
