Notes

• Package: 60-pin QFN (Quad Flat No-Lead)
• Power pins: IOVDD (I/O supply), DVDD (digital core supply), ADC_AVDD (ADC analog supply), and GND (ground) are distributed around the package
• ADC pins: GPIO26–GPIO29 have dual function as ADC channels (ADC0–ADC3)
• Debug pins: SWDIO and SWCLK appear at multiple locations (pins 23–24 and 52–53) for routing flexibility
• Crystal pins: XOUT appears at pins 22 and 54 for oscillator connection
• Pin numbering follows standard QFN convention: starting at pin 1 (top-left), proceeding counterclockwise around the perimeter
