According to the website it comes with a couple of PIC24's, a dsPIC33
and a PIC32.  The PIC32 is a PIC32MX250F128B which is one killer part.
83 MIPS, 128K flash, 32K RAM, so memory is practically unlimited.  It
has PPS so your can direct the peripherals to most pins (not total
flexibility but it is hard to think of a situation you couldn't
handle).=20

What I don't understand is how they get 83 MIPS out of a 50 MHz part.

Oh yeah, and Josh, the dsPICs and PIC32s have a combination of multiply
and divide PLLs so the frequency flexibility is much greater than the 8
bit parts.  I don't use the 24's all that much but I think they aren't
quite as flexible, but still a lot more than the PIC16s or PIC18s.

I'm using a PIC32MX250F128B in a project involving serial, and a 20MHz
crystal which doesn't divide nicely into a baud rate.  But after all the
PLLs the clock is fast enough that there are lots of divisor choices for
the baud rate generator, and I can get close enough, at least for 38.4.
I am communicating with a dsPIC30F4011 and a PIC16F87, both of which
have 7.3728 crystals which DO divide evenly.
