I have not yet read the errata. I was looking for a very small=20 (physically) uC with 18 I/O pins and as much speed as I can get, and=20 this is the best option so far at 4mm x 4mm in a QFN package. Don't really want to learn to use a new processor at this time, but=20 there are few other options. Next closest options were a QFN20 (3mm x=20 3mm, sweet!) STM32L011, but no one seems to stock it, and then it goes=20 down to a PIC161459 but get much slower at 25Mhz (~6.25 MIPS). I've actually gone the other way with Atmel, in that I'm more open to it=20 now since I have my Microchip FAE on tap who will usually chase down=20 answers for me when online support fails me (sadly often). Cheers, -Neil.
