Design Notes
Ensure proper decoupling of the VDD pins with 100 nF capacitors placed as close as possible to the MCU, and a bulk capacitor (e.g., 4.7 µF) on the main supply. For the analog supply (VDDA), use a separate 100 nF capacitor and, if possible, a ferrite bead to isolate from digital noise. The VREF+ pin should be connected to a stable reference voltage for accurate ADC readings.
For the 48-pin LQFP package, ensure adequate copper pour for the ground pins to minimize inductance. Place the crystal oscillator (if used) close to the OSC_IN/OSC_OUT pins with proper load capacitors. Keep high-speed communication lines (SPI, USART) short and avoid routing them near the analog section to reduce crosstalk.
Do not exceed the absolute maximum ratings for VDD (3.6V) and VDDA. Ensure the NRST pin is properly pulled up with a 100 nF capacitor to ground for reliable reset. When using the ADC, avoid floating input pins by configuring them as analog inputs and connecting to a known potential. For low-power modes, disable unused peripherals and clocks to achieve the specified current consumption.
