dsPIC33FJ12MC202
The dsPIC33FJ12MC202 PIM is designed to demon-
strate the capabilities of the dsPIC33FJ12MC202
family of general purpose devices using the
Explorer 16 Development Board and the PICtail™
Plus daughter boards.
The dsPIC33FJ12MC202 is a high-performance 16-bit
digital signal controller within a small 28-pin 6x6 mm
QFN package.
The dsPIC33FJ12MC202 is equipped with Peripheral
Pin Select (PPS), which allows many of the digital
peripherals to be remapped to use any number of pins
on the device.
The PIM takes advantage of PPS by using zero ohm
resistors to connect the I/O to the 100-pin Explorer 16
Development Board. Simply removing the zero ohm
resistors and using the test points associated with each
I/O pin (i.e., RP0, RP1, etc.), allows the designer to
reroute the pin to any of the available pins on the
Explorer 16 Development Board. This capability
enables easier and faster design times.
Table 1 shows the mapping between the Explorer 16
functions and the device pins.
