Design Notes

Decouple each VDD pin with a 100nF ceramic capacitor placed as close to the pin as possible. Additionally, connect a 4.7uF bulk capacitor to the main power rail. The VDDA pin should be connected to a clean analog supply, and VREF+ should be bypassed with a 1uF capacitor to ensure accurate ADC conversions. For battery-powered designs, use the VBAT pin for backup supply and connect a 100nF capacitor to it.

For reliable operation at 170 MHz, ensure a solid ground plane and minimize trace lengths for high-speed signals. Place the crystal oscillator (if used) close to the OSC_IN/OSC_OUT pins and keep the load capacitors within 5mm. Route the SWD interface (PA13/PA14) with proper impedance control to avoid signal integrity issues. Separate analog and digital ground planes and connect them at a single point near the VDDA pin.

Do not leave the NRST pin floating; connect a 100nF capacitor to ground and a 10k pull-up resistor to VDD. Ensure the BOOT0 pin is properly configured to select the desired boot mode. When using the ADC, avoid exceeding the maximum input voltage on any analog pin, and ensure VREF+ is within the specified range. Also, verify that the total current drawn from VDD does not exceed the maximum ratings.
