I've done a couple of projects with PIC32MM. Quite a nice cheap entry level 32-bit device family, must always check errata though.

would have become my goto if not for the ADC errata. Crazy cheap and good performance with USB. why would anyone use a M0+ is besides me. (unless for the ADC errata :( )

Code: [Select]
ADC 12-Bit Conversion The ADC may miss one or more of the following codes in 12-bit mode: 1023, 2046, 2047, 3070 and 3071.

ADC Format Options 32-bit signed format option is the same as the 16-bit signed format option.

These seem to be the remaining ADC errata as of revision A4.  Would you mind sharing what makes these a deal breaker for you?  I've been evaluating the pic32mm with a usb dev board and just curious what your thoughts are, thanks!

Different applications have different requirements.
For many applications a few missing ADC codes would not be an issue, but yeh, it's not ideal.
Peruse the errata and datasheet then you can decide if it meets your application requirements.

With Microchip parts its often worth reading the errata first :P
