Design Notes
Ensure adequate decoupling on all VDD and VDDA pins. Use 100nF ceramic capacitors close to each power pin and a 4.7uF bulk capacitor. The VDDA pin should have a dedicated 1uF capacitor and a ferrite bead to isolate analog noise.
For high-speed USB and SDIO interfaces, maintain controlled impedance traces and keep trace lengths short. Use a ground plane to minimize EMI and ensure signal integrity. Place the crystal oscillator close to the MCU with proper load capacitors.
Do not exceed the absolute maximum ratings for VDD (3.6V). Ensure the BOOT0 pin is properly configured to avoid unintended boot modes. When using the ART Accelerator, verify Flash wait states are correctly set for the clock frequency.
Compliance Information
RoHS compliant per STMicroelectronics product page. Not AEC-Q100 qualified.
