Design Notes
Decouple each VDD pin with a 100nF ceramic capacitor placed as close as possible to the pin. Add a 4.7uF bulk capacitor on the main supply. For VDDA, use a ferrite bead and a 1uF capacitor to filter analog noise. Ensure VDD and VDDA are connected through a low-impedance path.
For the LQFP144 package, use a 4-layer PCB with a solid ground plane. Route high-speed signals (Ethernet, USB) with controlled impedance (e.g., 90 ohms differential for USB). Keep crystal oscillator traces short and away from noisy signals. Place the decoupling capacitors on the bottom side directly under the MCU if possible.
Ensure the BOOT0 pin is correctly configured to boot from Flash (tied low). Do not leave NRST floating; connect a 100nF capacitor to ground. For Ethernet, use a magnetics module with proper termination. When using the cryptographic accelerator, ensure the clock is enabled and the TRNG is seeded correctly.
Compliance Information
