Memory and peripheral allocation
The 47 general-purpose I/O lines are shared with the serial interfaces — I²C, SPI, SSP, and two UARTs — so the pin allocation must be planned early in the layout. The internal oscillator saves an external crystal for non-critical timing, though a precision clock is advisable if the ADC or DAC accuracy is pushed to its 10-bit limit.
