The PIC24FJ256GB110 is specifically designed to be used in conjunction with the USB PICtail Plus Daughter Board to allow development of USB applications. Because a few pins on the device are dedicated to the USB module, several of the existing features of the Explorer 16 must be rerouted on the PIC24FJ256GB110 PIM. The Peripheral Pin Select (PPS) feature, available on this device, allows the existing peripherals to be remapped to the new I/O pins. Features • Enables designs for USB device, embedded host and On-The-Go (OTG) when used in conjunction with the USB PICtail Plus Daughter Board. Hardware Options The PIC24FJ256GB110 PIM has been configured to run with the core voltage regulator enabled and the USB voltage regulator disabled. • Disabling the core voltage regulator – R4 pulls ENVREG high enabling the core voltage regulator. In order to modify the board such that the device runs with the voltage regulator disabled, populate R3 with a zero ohm resistor. Once the core voltage regulator is disabled, a voltage of 2.0V-2.7V needs to be applied to the VDDCORE pin. R2 has been added such that a zero ohm resistor that is populated here will short VDDCORE to VDD. This would require that the Explorer 16 be run from an external power supply of the correct voltage and not from the on-board voltage regulators. Alternatively, this pad can be used to attach an external power supply just to VDDCORE such that the pads will still operate at the Explorer 16 VDD, but the PIC24FJ256GB110 core will run at the lower supplied voltage. Signal Interface Below is a table of all the pins on the device that are remapped.
