The K series form Microchip are one of the fastest series of microcontrollers with a lot of good changes at the peripheral level, and I will refer further at the 5Vcc microcontroller, PIC18F46K22, as a very good alternative to ATmega644P microcontroller.
So, to learn about it, I built a new development board. This will help me compare it with the ATMEL rival but the same time, it will help me in developing new libraries and applications using one (or all) of the free compilers available.I had from the start an annoying restriction regarding board size: it couldn't be bigger than 100x75 mm. I had to decide what peripherals and how many could place on the board. So initially this one "popped" out:
