Design Notes
Ensure all VDD pins are decoupled with 100nF ceramic capacitors placed as close to the pins as possible. Additionally, use a 10uF bulk capacitor on the main supply. The device has an internal voltage regulator for the core; connect the VCAP pin with a 10uF capacitor as specified in the datasheet. Proper decoupling is critical for stable operation at 200MHz.
For the 64-VQFN package, use a thermal pad connected to ground with multiple vias for heat dissipation. Ensure the PCB layout follows Microchip's recommendations for high-speed ADC and PWM signals, keeping analog and digital grounds separate. Route high-speed signals with controlled impedance and minimize trace lengths to reduce noise.
When programming via ICSP, use a single PGECx/PGEDx pair consistently. Do not mix pairs. Also, ensure the device is properly reset with a pull-up resistor on MCLR. For functional safety applications, enable the built-in self-test and ECC features. Avoid exceeding the absolute maximum ratings on any pin.
