Hi everyone,
I searched at the Microchip's web side but I didn't manage to find the pic that I want. So I am asking if there is any PIC that makes the analog to digital conversion of 8 channels at most at 20usec all of them and can achieve 230400 baud rate of the usart.

I am sure there are many that will fit the criteria. The PIC24FJ64GA002 and related family members are one example. These PICs feature an A/D capable of sampling at 500Ksps (2us per sample). In addition you can automate the process. Basically you establish a mask of the A/D inputs you want sampled and start the conversion process. The PIC will sample all channels as identified in the mask and store each value in registers dedicated for this function.

Sorry for my mistake. I forgot to mention that I want to be 8-bit. Have you something in your mind?
