Catatan Desain
Ensure proper decoupling of the VDD pins with 100nF ceramic capacitors placed as close as possible to each VDD pin. Additionally, use a 4.7µF or larger bulk capacitor near the power input. For battery-powered designs, consider using the low-power modes to reduce average current consumption. The STM32L010RBT6 supports a supply voltage range of 1.8V to 3.6V, so verify that the power supply remains within this range under all load conditions.
Use a solid ground plane and keep high-frequency traces short to minimize EMI. For the crystal oscillator pins (PF0/PF1), place the crystal and load capacitors close to the MCU and ensure a clean ground connection. Follow the layout guidelines in the STM32L0 reference manual (RM0377) for optimal performance. Avoid routing high-speed signals near the oscillator circuit to prevent interference.
When using the RTC, ensure the VBAT pin is connected to a backup battery or a capacitor to maintain timekeeping during main power loss. Also, configure the RTC clock source correctly (LSE or LSI) to avoid unexpected behavior. For programming, use the SWD interface (PA13/PA14) and ensure the BOOT0 pin is set correctly for boot mode. Do not leave unused GPIO pins floating; configure them as outputs or enable pull-ups/pull-downs to reduce leakage current.
