设计说明
Decouple the VDD and VDDA pins with 100 nF ceramic capacitors placed as close to the pins as possible. Additionally, use a 4.7 uF capacitor on VDDA for analog noise filtering. The VBAT pin should be connected to a backup battery or tied to VDD if not used.
For the UFQFPN-48 package, ensure the exposed pad is soldered to a ground plane for proper thermal dissipation. Use thermal vias under the pad to improve heat transfer. Follow the recommended land pattern in the datasheet for reliable soldering.
When using the STM32F401CEU6, ensure the BOOT0 pin is properly configured to select the desired boot mode. Also, note that the PF0 and PF1 pins are used for the external crystal oscillator; if not used, they can be configured as GPIO. Avoid exceeding the absolute maximum ratings for supply voltage and I/O pins.
