dsPIC33FJ32GP204
The dsPIC33FJ32GP204 PIM is designed to demon-
strate the capabilities of the dsPIC33FJ32GP204
family of general purpose devices using the
Explorer 16 Development Board and the PICtail™
Plus daughter boards.
The dsPIC33FJ32GP204 is a high-performance 16-bit
digital signal controller within a small 44-pin QFN
package.
The dsPIC33FJ32GP204 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., Pin1, Pin2, 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.
