Design Notes

Decouple each VDD pin with a 100 nF ceramic capacitor placed as close as possible to the pin, and add a 1 µF capacitor at the main power entry. For the VDDA pin, use a 1 µF and 100 nF pair to ensure stable ADC reference. The VBAT pin should be connected to a backup battery or tied to VDD through a diode to maintain RTC operation during main power loss.

For the LQFP-100 package, ensure a solid ground plane under the device. Route the crystal oscillator (OSC_IN/OSC_OUT) with short traces and keep them away from high-speed digital lines. Place the decoupling capacitors for the crystal as close as possible to the pins. Use a 4-layer PCB with dedicated power and ground planes for optimal EMC performance.

Do not leave unused GPIO pins floating; configure them as outputs or enable internal pull-ups/pull-downs to avoid excessive leakage. When using the LCD controller, ensure the LCD voltage (VLCD) is properly generated and decoupled. For low-power modes, disable unused peripherals and clocks to achieve the specified standby current. Also, note that the BOOT0 pin must be tied to a defined level to avoid accidental boot mode changes.
