Pinout

Pin Name Type Function
1 PB04 bidirectional General-purpose I/O (TTa type, analog-capable) with digital alternates UART2_TXD, RTC_OUT, ADC_SAM, BTIM1_ETR, BTIM2_TOGP, GTIM_CH3, ATIM_CH1 and analog inputs ADC_IN11 and VC2_CH3.
2 PB05 bidirectional General-purpose I/O (TTa type, analog-capable) with digital alternates UART2_TXD, RTC_TAMP, SPI_MISO, I2C_SDA, GTIM_ETR, GTIM_CH2, ATIM_CH5 and analog inputs ADC_IN12 and VC1_CH0.
3 PB06 bidirectional General-purpose I/O (TTa type, analog-capable) with digital alternates UART2_RXD, RTC_OUT, SPI_MOSI, I2C_SCL, ATIM_ETR, GTIM_CH1, ATIM_CH5N and analog inputs ADC_IN13 and VC2_CH0.
4 PB07/NRST input Default function is the chip reset input (NRST, RST type, input only); it can alternatively be used as a GPIO that is input-only, selected via the SYSCTRL_CR2.RSTIO bit field.
5 PA00 bidirectional General-purpose I/O (TTa type, analog-capable) with digital alternates UART1_RXD, I2C_SDA, SPI_SCK, BTIM1_TOGP, BTIM3_ETR, ATIM_BK2, ATIM_CH4 and analog functions ADC_IN0, VC1_CH1, OSC_IN.
6 PA01 bidirectional General-purpose I/O (TTa type, analog-capable) with digital alternates UART1_TXD, I2C_SCL, SPI_CS, BTIM1_TOGN, GTIM_CH3, ATIM_BK, ATIM_CH4N and analog functions ADC_IN1, OSC_OUT.
7 VSS power_in Ground pin of the device.
8 Vcore power_out Internal regulator supply output; it must be connected to ground through a 100nF to 470nF capacitor and is for internal circuit use only.
9 VDD power_in Power supply pin; the operating voltage range is 1.62V to 5.5V and all VDD pins must be supplied at the same voltage.
10 PA02 bidirectional General-purpose I/O (TTa type, analog-capable) with digital alternates PCLK_OUT, SPI_CS, VC1_OUT, IR_OUT, ATIM_ETR, ATIM_CH1N and analog input ADC_IN2.
11 PB00 bidirectional General-purpose I/O (TTa type, analog-capable) with digital alternates UART1_RXD, UART2_CTS, SPI_SCK, I2C_SDA, LVD_OUT, BTIM3_TOGP, ATIM_CH1 and analog functions ADC_IN7, OSC32_OUT.
12 PB01 bidirectional General-purpose I/O (TTa type, analog-capable) with digital alternates UART1_TXD, UART2_RTS, SPI_CS, I2C_SCL, ADC_SAM, BTIM3_TOGN, ATIM_CH2 and analog functions ADC_IN8, OSC32_IN.
13 PA03 bidirectional General-purpose I/O (TTa type, analog-capable) with digital alternates UART2_TXD, LPTIM_CH1, SPI_MISO, BTIM1_ETR, IR_OUT, GTIM_CH4, ATIM_CH3 and analog functions ADC_IN3, VC1_CH2, LVD_CH1.
14 PA04 bidirectional General-purpose I/O (TTa type, analog-capable) with digital alternates UART2_RXD, LPTIM_CH2, SPI_MOSI, MCO_OUT, VC2_OUT, GTIM_CH3, ATIM_CH1N and analog input ADC_IN4.
15 PA05 bidirectional General-purpose I/O (TTa type, analog-capable) with digital alternates UART1_RXD, LPTIM_OUT, SPI_SCK, I2C_SDA, HEXEN, GTIM_CH2, ATIM_CH2N and analog functions ADC_IN5, VC2_CH1.
16 PA06 bidirectional General-purpose I/O (TTa type, analog-capable) with digital alternates UART1_TXD, LPTIM_ETR, SPI_MOSI, I2C_SCL, BTIM2_ETR, GTIM_CH1, ATIM_CH3N and analog input ADC_IN6.
17 PA07/SWDIO bidirectional Standard I/O (TC type) with digital alternates UART1_RXD, I2C_SDA, SPI_MISO, LPTIM_OUT, BTIM2_TOGP, ATIM_BK, ATIM_CH6; after reset it is configured as the SWDIO debug function with the internal pull-up enabled.
18 PA08/SWCLK bidirectional Standard I/O (TC type) with digital alternates UART1_TXD, I2C_SCL, MCO_OUT, VC1_OUT, BTIM2_TOGN, ATIM_BK2, ATIM_CH6N; after reset it is configured as the SWCLK debug function with the internal pull-up enabled.
