- Wide supply voltage range (1.71V to 3.6V) (vs GD32F450VGT6)
Design Notes
Decouple each VDD pin with a 100 nF ceramic capacitor placed as close as possible to the pin. Additionally, place a 4.7 uF bulk capacitor on the main supply. For VDDA, use a 1 uF capacitor and a ferrite bead to isolate analog noise. Ensure the ground plane is solid and continuous to minimize noise.
For the 100-LQFP package, use a 0.5 mm pitch land pattern. Provide a thermal pad on the PCB for the exposed pad (if present) to improve heat dissipation. Route high-speed signals (USB, SPI) with controlled impedance and keep traces short. Place the crystal oscillator close to the OSC_IN/OSC_OUT pins with proper load capacitors.
Do not exceed the absolute maximum ratings for supply voltage (3.6V) or I/O pins. Ensure the BOOT0 pin is properly configured to avoid accidental boot from system memory. When using low-power modes, configure all unused GPIOs to analog mode to reduce leakage current. Also, verify that the RTC backup domain is powered correctly if using VBAT.
Compliance Information
