Design Notes
The STM32G030F6P6 operates from 2.0V to 3.6V. Use a 100nF decoupling capacitor close to each VDD/VSS pair and a 1uF capacitor on VDDA. For battery-powered designs, consider the low-power modes (Sleep, Stop, Standby) to minimize current consumption. Ensure the power supply is stable and within the specified range to avoid brown-out resets.
For the 20-pin TSSOP package, ensure proper PCB layout with a solid ground plane. Keep analog and digital grounds separate and connect them at a single point. Place the crystal (if used) close to the OSC pins with proper load capacitors. For high-speed I2C (Fm+), minimize trace length and capacitance to maintain signal integrity.
Do not exceed the absolute maximum ratings, especially on supply voltage and I/O pins. Ensure the NRST pin is properly pulled up with a 100nF capacitor to ground for reliable reset. When using the ADC, avoid floating input pins and use appropriate sampling time. For I2C, ensure pull-up resistors are correctly sized for the bus speed.
