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. Connect VDDA to a clean analog supply through a ferrite bead and add a 1uF capacitor to VSSA. Ensure VREF+ is filtered with a 1uF capacitor for accurate ADC conversions.
For the LQFP144 package, use a 4-layer PCB with dedicated power and ground planes. Keep high-speed signals (Ethernet, USB) impedance-controlled and routed over a solid ground plane. Place the crystal oscillator close to the OSC_IN/OSC_OUT pins with short traces and a ground guard ring to minimize noise.
Ensure the BOOT0 pin is configured correctly to boot from Flash (pull-down for main Flash). The NRST pin requires a 100nF capacitor to ground and a 10k pull-up resistor. Do not leave unused I/O pins floating; configure them as outputs or enable internal pull-ups to avoid excessive current consumption.
Compliance Information
RoHS compliant per STMicroelectronics product page. Not AEC-Q100 qualified; for automotive, consider STM32F405ZGT7 with extended temperature range.
