Ghi chú thiết kế
Ensure proper decoupling of the power supply. Place a 100 nF ceramic capacitor close to each VDD pin and a 4.7 uF bulk capacitor near the power input. The VDDA pin should be filtered with a ferrite bead and a 1 uF capacitor to reduce analog noise. This is critical for ADC accuracy and stable operation.
For the LQFP100 package, use a 4-layer PCB with a solid ground plane. Route high-speed signals (Ethernet, USB) with controlled impedance (e.g., 50 ohm for Ethernet). Keep crystal oscillator traces short and away from high-current traces. Add a ground pour around the MCU to reduce EMI.
Ensure the BOOT0 pin is configured correctly for the desired boot mode (Flash, system memory, or SRAM). A floating BOOT0 pin can cause unexpected boot behavior. Also, the NRST pin should have a 100 nF capacitor to ground for reliable reset. Do not exceed the absolute maximum ratings for supply voltage (3.6V) to avoid damage.
