Ghi chú thiết kế
Ensure proper decoupling of the VDD pins with 100nF ceramic capacitors placed as close as possible to each VDD pin. Additionally, use a 4.7uF bulk capacitor on the main power rail. The STM32G070RBT6 operates from 2.0V to 3.6V, so verify that the power supply stays within this range during all operating conditions, including transients.
For the LQFP64 package, ensure adequate copper pour for the ground pins to minimize inductance. Place the decoupling capacitors on the same side of the PCB as the MCU, close to the pins. If using an external crystal, place it near the OSC_IN/OSC_OUT pins (PF0/PF1) with proper load capacitors as specified in the datasheet. Keep high-speed communication lines (SPI, USART) away from noisy power traces.
Do not leave the NRST pin floating; connect it to VDD through a 100nF capacitor and a 10kOhm pull-up resistor. Ensure the BOOT0 pin is properly configured for the desired boot mode. When using the ADC, avoid exceeding the maximum input voltage (VDD+0.3V) on any analog pin. Also, note that the STM32G070RBT6 does not have a DAC, so if your application requires analog output, consider the STM32G071RBT6 instead.
