Key Differentiators
- Integrated USB 2.0 PHY (vs PIC24FJ128GA008-I/PT)
- Ultra-low-power architecture (vs PIC24FJ128GA008-I/PT)
- Higher ADC resolution (vs PIC24FJ128GA008-I/PT)
Design Notes
Decouple the VCC and AVCC pins with 100nF and 10uF capacitors placed as close to the pins as possible. The AVCC pin should have a separate 10uF capacitor to filter analog noise. Use a low-ESR ceramic capacitor for high-frequency decoupling. Ensure the power supply can handle the peak current during Flash programming or USB operation, which can be higher than the average current.
For USB operation, route the D+ and D- traces as a differential pair with controlled impedance (90 ohms). Keep the traces short and avoid vias to minimize signal integrity issues. Place the USB PHY components close to the MCU. For the crystal oscillator, place the crystal and load capacitors close to the XIN/XOUT pins and keep the traces short to reduce parasitic capacitance.
Ensure the RST/NMI pin is properly pulled up with a 47k ohm resistor and a 100nF capacitor to ground to prevent spurious resets. Do not leave unused I/O pins floating; configure them as outputs or enable internal pull-ups. When using the ADC, ensure the reference voltage is stable and bypassed with a capacitor. Also, verify that the supply voltage does not exceed the absolute maximum rating of 4.1V.
