Design Notes

For ultra-low-power operation, configure unused GPIOs as analog inputs to avoid leakage currents. Use the low-power modes (Stop 2, Standby, Shutdown) to minimize power consumption. The shutdown mode consumes only 100 nA, making it ideal for battery-powered devices. Ensure the power supply is stable and decoupled with 100 nF capacitors close to each VDD pin and a 4.7 uF capacitor at the main supply.

Place decoupling capacitors (100 nF) as close as possible to each VDD pin, and a 4.7 uF bulk capacitor at the main supply. For the crystal oscillator, place the crystal and load capacitors close to the OSC_IN/OSC_OUT pins to minimize parasitic capacitance. Use a ground plane to reduce noise and improve EMC performance.

Ensure the BOOT0 pin is properly configured to select the correct boot mode. For SWD programming, connect PA13 (SWDIO) and PA14 (SWCLK) with pull-up/pull-down resistors as recommended in the datasheet. Avoid driving the VBAT pin with more than 3.6V to prevent damage to the backup domain.
