Design Notes
Ensure proper decoupling of VDD and VDD_HV pins with 100nF ceramic capacitors placed as close to the pins as possible. Use a 10uF bulk capacitor on the main power rail. The device operates from 3.3V to 5V, so verify the supply voltage is within this range under all load conditions.
For the crystal oscillator circuit, place the crystal and load capacitors close to the OSC pins to minimize parasitic capacitance and ensure stable startup. Use a ground plane under the MCU to reduce noise and improve EMC performance.
Do not exceed the absolute maximum ratings for VDD and VDD_HV. Ensure the reset pin is properly pulled up and that the watchdog timer is configured correctly to avoid unintended resets. When programming flash, follow the recommended sequence to prevent corruption.
