PIC32MX460F512L Pin Out
|
||||||
|
=======================
|
||||||
|
|
||||||
|
PIC32MX460F512L 100-Pin TQFP (USB) Pin Out. The mapping to the pins on
|
||||||
|
the PCL Logic board are very simple, each pin is brought out to a connector
|
||||||
|
label with the PIC32MX460F512L pin number.
|
||||||
|
|
||||||
|
On board logic only manages power, crystal, and USB signals.
