CW32L010F8U6 from CW, in a QFN-20-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | PB07/NRST | input | Default function is the chip reset input (RST type); it can alternatively be configured as a GPIO that is input-only, selected by SYSCTRL_CR2.RSTIO. |
| 2 | PA00 | bidirectional | TTa I/O 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. |
| 3 | PA01 | bidirectional | TTa I/O with digital alternates UART1_TXD, I2C_SCL, SPI_CS, BTIM1_TOGN, GTIM_CH3, ATIM_BK, ATIM_CH4N and analog functions ADC_IN1, OSC_OUT. |
| 4 | VSS | power_in | Ground reference pin for the device; all voltages are specified relative to VSS. |
| 5 | 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. |
| 6 | VDD | power_in | Main power supply pin with a standard operating range of 1.62 V to 5.5 V; all VDD pins must be supplied at the same voltage. |
| 7 | PA02 | bidirectional | TTa I/O with digital alternates PCLK_OUT, SPI_CS, VC1_OUT, IR_OUT, ATIM_ETR, ATIM_CH1N and analog function ADC_IN2. |
| 8 | PB00 | bidirectional | TTa I/O with digital alternates UART1_RXD, UART2_CTS, SPI_SCK, I2C_SDA, LVD_OUT, BTIM3_TOGP, ATIM_CH1 and analog functions ADC_IN7, OSC32_OUT. |
| 9 | PB01 | bidirectional | TTa I/O with digital alternates UART1_TXD, UART2_RTS, SPI_CS, I2C_SCL, ADC_SAM, BTIM3_TOGN, ATIM_CH2 and analog functions ADC_IN8, OSC32_IN. |
| 10 | PA03 | bidirectional | TTa I/O 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. |
| 11 | PA04 | bidirectional | TTa I/O with digital alternates UART2_RXD, LPTIM_CH2, SPI_MOSI, MCO_OUT, VC2_OUT, GTIM_CH3, ATIM_CH1N and analog function ADC_IN4. |
| 12 | PA05 | bidirectional | TTa I/O with digital alternates UART1_RXD, LPTIM_OUT, SPI_SCK, I2C_SDA, HEXEN, GTIM_CH2, ATIM_CH2N and analog functions ADC_IN5, VC2_CH1. |
| 13 | PA06 | bidirectional | TTa I/O with digital alternates UART1_TXD, LPTIM_ETR, SPI_MOSI, I2C_SCL, BTIM2_ETR, GTIM_CH1, ATIM_CH3N and analog function ADC_IN6. |
| 14 | PA07/SWDIO | bidirectional | TC standard I/O that after reset is configured as the SWDIO function with internal pull-up enabled; digital alternates include UART1_RXD, I2C_SDA, SPI_MISO, LPTIM_OUT, BTIM2_TOGP, ATIM_BK, ATIM_CH6. |
| 15 | PA08/SWCLK | bidirectional | TC standard I/O that after reset is configured as the SWCLK function with internal pull-up enabled; digital alternates include UART1_TXD, I2C_SCL, MCO_OUT, VC1_OUT, BTIM2_TOGN, ATIM_BK2, ATIM_CH6N. |
