dsPIC Controller

Figure 2: dsPIC33FJ128MC708 pin assignment

The dsPIC Controller used is mounted on as 80-PIN so it is easy to solder. The board is targeted to dsPIC33FJ128MC708 but also a Pin compatibles can be used. In figure 2 the pin assignment is shown. The Reset is connected to button and also is used by the ICSP¹. The board is derived from the microchip development board Explorer 16 with the PICtail Ethernet interface.

The PIC can be clocked with a Oscillator, which is also used for the Ethernet processor ENC28J60, therefore 25MHz is used, but also the internal RC can be used. I recommend the oscillator since seems to be the most stable solution. The frequency can be choosen with internals PLLs and Prescaler.
