Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | PD4 | bidirectional | Port D I/O that is 5 V tolerant (FT); alternate functions include MCO, ADC_ETR, I2C_SMBA, UART1_TX, UART2_TX, SPI_MOSI, TIM1_CH4, TIM2_CH1 and EXTI4, and all I/O are in analog mode during and after reset unless stated otherwise. |
| 2 | PD5 | bidirectional | Port D I/O that is not 5 V tolerant; alternate functions include SWDIO (debug data), MCO, ADC_ETR, UART1_TX, UART2_TX, SPI_MISO, TIM1_ETR, TIM2_ETR, EXTI5 and analog input ADC_AIN0. |
| 3 | PD6 | bidirectional | Port D I/O that is not 5 V tolerant; alternate functions include MCO, ADC_ETR, I2C_SMBA, UART1_RX, UART2_RX, SPI_MISO, TIM1_CH2, TIM2_CH2, EXTI6 and analog input ADC_AIN1. |
| 4 | NRST_PA0 | bidirectional | 5 V tolerant (FT) pin that serves as the active-low external reset input NRST (internal pull-up; low pulses shorter than 80 ns are ignored) or as GPIO PA0, with alternate functions I2C_SMBA, UART1_TX, UART2_TX, SPI_NSS, TIM1_BKIN, TIM2_CH3, ADC_ETR and EXTI0. |
| 5 | PA1 | bidirectional | 5 V tolerant (FT) GPIO that can also act as external clock input EXTCLK1 (GPIO external clock up to 32 MHz), with alternate functions I2C_SCL, UART1_TX, UART2_TX, SPI_SCK, TIM1_CH1N, TIM2_ETR, ADC_ETR and EXTI1. |
| 6 | PA2 | bidirectional | 5 V tolerant (FT) GPIO with alternate functions I2C_SMBA, UART1_RX, UART2_RX, SPI_SCK, TIM1_CH2N, TIM2_CH4, ADC_ETR and EXTI2, and additional wake-up function WKUP3. |
| 7 | VSS/VSSA | power_in | Ground pin; all VDD and VSS pins must be connected to the external supply system, and the voltage difference between different ground pins must not exceed 50 mV. |
| 8 | PD7 | bidirectional | 5 V tolerant (FT) GPIO with alternate functions I2C_SMBA, UART1_RX, UART2_RX, SPI_NSS, TIM1_BKIN, TIM1_CH3, TIM2_CH1, EXTCLK2_MCO, ADC_ETR and EXTI7, where the TIM1_CH3/TIM1_BKIN choice requires additional IOMUX register configuration. |
| 9 | VDD/VDDA | power_in | Single supply pin for the digital and analog circuits (VDD and VDDA are tied together internally), specified at 2.4 V to 5.5 V. |
| 10 | PA3 | bidirectional | 5 V tolerant (FT) GPIO with alternate functions MCO, ADC_ETR, I2C_SDA, UART1_TX, UART2_TX, SPI_NSS, TIM1_CH3N, TIM2_CH3 and EXTI3. |
| 11 | PB5 | bidirectional | 5 V tolerant (FT) GPIO with SWCLK (SWD clock) as an alternate function, plus ADC_ETR, I2C_SDA, UART1_RX, UART2_RX, SPI_NSS, TIM1_BKIN, TIM2_CH2, EXTCLK3 and EXTI5. |
| 12 | PB4 | bidirectional | 5 V tolerant (FT) GPIO with alternate functions ADC_ETR, I2C_SCL, UART1_RX, UART2_RX, SPI_MISO, TIM1_CH2N, TIM2_ETR and EXTI4. |
| 13 | PC3 | bidirectional | 5 V tolerant (FT) GPIO with alternate functions MCO, ADC_ETR, I2C_SCL, UART1_TX, UART2_TX, SPI_MOSI, TIM1_CH1N, TIM1_CH3, TIM2_CH1 and EXTI3, where the TIM1 CH3/CH1N choice requires additional IOMUX configuration. |
| 14 | PC4 | bidirectional | Port C I/O that is not 5 V tolerant; alternate functions include ADC_ETR, I2C_SDA, UART1_RX, UART2_RX, SPI_MISO, TIM1_CH2N, TIM1_CH4, TIM2_CH4, WKUP1 and EXTI4, and analog input ADC_AIN2. |
| 15 | PC5 | bidirectional | 5 V tolerant (FT) GPIO with alternate functions ADC_ETR, I2C_SDA, UART1_TX, UART2_TX, SPI_SCK, TIM1_ETR, TIM2_CH1, EXTCLK4 and EXTI5. |
| 16 | PC6 | bidirectional | Port C I/O that is not 5 V tolerant; alternate functions include ADC_ETR, I2C_SCL, UART1_RX, UART2_RX, SPI_MOSI, TIM1_CH1, TIM2_CH3 and EXTI6, and analog input ADC_AIN6. |
| 17 | PC7 | bidirectional | 5 V tolerant (FT) GPIO with alternate functions ADC_ETR, I2C_SCL, UART1_RX, UART2_RX, SPI_MISO, TIM1_CH2, TIM2_ETR and EXTI7, and additional wake-up function WKUP2. |
| 18 | PD1 | bidirectional | Port D I/O that is not 5 V tolerant; alternate functions include ADC_ETR, I2C_SMBA, UART1_TX, UART2_TX, SPI_MOSI, TIM1_CH1, TIM2_CH4 and EXTI1, and analog input ADC_AIN5. |
