Design Notes
Ensure proper decoupling of the VDD and VDDA pins with 100 nF ceramic capacitors placed as close to the pins as possible. Additionally, use a 4.7 µF capacitor on VDDA for analog noise filtering. The supply voltage range is 2.0V to 3.6V; do not exceed these limits to avoid damage.
For the LQFP-48 package, follow the recommended land pattern in the datasheet. Provide a solid ground plane under the MCU to minimize noise and improve thermal performance. Keep high-speed signals (SPI, USART) away from the crystal oscillator pins to reduce interference.
When using the internal RC oscillator, be aware of its accuracy (±1% typical). For applications requiring precise timing, use an external crystal. Also, configure the boot pins correctly to select the desired boot mode; incorrect settings can prevent the MCU from starting.
Compliance Information
