Key Differentiators
- Integrated 12-bit DAC (vs STM32G031F8P6)
- Hardware RNG and CRC (vs STM32G031F8P6)
- Higher clock frequency (vs LPC812M101JDH20)
Design Notes
Decouple the VDD and VDDA pins with 100nF ceramic capacitors placed as close to the pins as possible. Additionally, add a 4.7Β΅F bulk capacitor on VDD. For VDDA, use a ferrite bead in series with the supply to filter high-frequency noise, especially when using the ADC. Ensure the ground connections are low-impedance to minimize noise coupling.
For the TSSOP-20 package, ensure the PCB land pattern matches the recommended dimensions in the datasheet. Use a 0.65mm pitch with appropriate pad sizes. Provide a solid ground plane under the device to reduce EMI and improve thermal performance. Keep high-speed signals (SPI, USART) away from the crystal oscillator pins to avoid interference.
When using the internal HSI oscillator, note that its accuracy is Β±1% after calibration. For applications requiring precise timing, use an external crystal (HSE) or calibrate the HSI using the RTC. Also, ensure the NRST pin is properly pulled up with a 100nF capacitor to ground to prevent spurious resets. Do not leave unused GPIO pins floating; configure them as outputs or enable internal pull-ups.
