here you have the datasheet.
Its an 28 pin device so its a bit big for this thing.
I wod go whith the PIC16F88.It has PWM,ADC,and some pins for meaby brightnes setting.
You can also check the TC4422 (2A load driver whith CMOS/TTL input)
They have all kinds of datashets here:

Cod you jay (or anyone) send me the PIC16F876A.dev and PIC12F675.dev from MPLAB.Tipe it in serach and send them to me (I need them for WinPIC but i cant download MPLAB)
