Notes
- Package: QFN-20-EP(3x3) with exposed pad (EP)
- Pin 9 (NRST): Active-low reset input; typically requires external pull-up and decoupling capacitor
- Pin 10 (VSS): Ground; multiple ground connections recommended for proper layout
- Pin 11 (VCC): Main power supply; requires decoupling capacitor (typically 100 nF ceramic + 10 µF bulk)
- Exposed Pad (EP): Should be connected to ground (VSS) for thermal and electrical performance
- Port A (PA0–PA15): 16 GPIO pins with multiple alternate functions (SPI, USART, TIM1, ADC, comparator)
- Port B (PB0–PB7): 8 GPIO pins with alternate functions (SPI, I2C, timers)
- Port F (PF0–PF4): Not present in QFN-20 package (available only in larger packages like LQFP32/QFN32)
- SWD Debug: PA13 (SWD_IO) and PA14 (SWD_CLK) support serial wire debug interface
- All GPIO pins support external interrupts (EXTI) and are 5V-tolerant when operating at 5V supply
