GD32E230K8U6 from GigaDevice Semicon Beijing, in a QFN-32-EP(5x5). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Digital supply, 2.6-3.6 V. Bypass with 100 nF close to the pin (share bulk cap with pin 17).
2 PF0/OSCIN bidirectional Muxed GPIO PF0 / HXTAL oscillator input (OSCIN) / I2C0_SDA alternate function. 5 V tolerant when used as digital I/O; drive from a crystal or external clock when configured as OSCIN.
3 PF1/OSCOUT bidirectional Muxed GPIO PF1 / HXTAL oscillator output (OSCOUT) / I2C0_SCL alternate function. 5 V tolerant when used as digital I/O.
4 NRST bidirectional Active-low system reset, bi-directional open-drain with internal pull-up. Drive low externally to reset the MCU; pulled low internally during a power-on / watchdog / software reset.
5 VDDA power_in Analog supply for ADC and comparator, 2.6-3.6 V. Must be tied to VDD (through a ferrite/filter for best ADC performance) and bypassed with 100 nF + 1 µF.
6 PA0/WKUP bidirectional General-purpose I/O PA0 with multiple alternate functions: USART0_CTS / USART1_CTS, CMP_OUT, I2C1_SCL; additional analog ADC_IN0, CMP_IM6, RTC_TAMP1, and WKUP0 wake-up source.

9 PA3 bidirectional General-purpose I/O PA3. Alternate: USART0_RX, USART1_RX, TIMER14_CH1. Additional: ADC_IN3.
10 PA4 bidirectional General-purpose I/O PA4. Alternate: SPI0_NSS, I2S0_WS, USART0_CK, USART1_CK, TIMER13_CH0, SPI1_NSS. Additional: ADC_IN4, CMP_IM4.
11 PA5 bidirectional General-purpose I/O PA5. Alternate: SPI0_SCK, I2S0_CK. Additional: ADC_IN5, CMP_IM5.
12 PA6 bidirectional General-purpose I/O PA6. Alternate: SPI0_MISO, I2S0_MCK, TIMER2_CH0, TIMER0_BRKIN, TIMER15_CH0, EVENTOUT, CMP_OUT. Additional: ADC_IN6.
13 PA7 bidirectional General-purpose I/O PA7. Alternate: SPI0_MOSI, I2S0_SD, TIMER2_CH1, TIMER13_CH0, TIMER0_CH0_ON, TIMER16_CH0, EVENTOUT. Additional: ADC_IN7.
14 PB0 bidirectional General-purpose I/O PB0. Alternate: TIMER2_CH2, TIMER0_CH1_ON, USART1_RX, EVENTOUT. Additional: ADC_IN8.
15 PB1 bidirectional General-purpose I/O PB1. Alternate: TIMER2_CH3, TIMER13_CH0, TIMER0_CH2_ON, SPI1_SCK. Additional: ADC_IN9.
16 PB2 bidirectional General-purpose I/O PB2. 5 V tolerant. Alternate: TIMER2_ETI.
17 VDD power_in Second digital supply pin, 2.6-3.6 V. Tie to the same rail as pin 1 and bypass locally with 100 nF.
18 PA8 bidirectional General-purpose I/O PA8. 5 V tolerant. Alternate: USART0_CK, TIMER0_CH0, CK_OUT, USART1_TX, EVENTOUT.
19 PA9 bidirectional General-purpose I/O PA9. 5 V tolerant. Alternate: USART0_TX, TIMER0_CH1, TIMER14_BRKIN, I2C0_SCL, CK_OUT.
20 PA10 bidirectional General-purpose I/O PA10. 5 V tolerant. Alternate: USART0_RX, TIMER0_CH2, TIMER16_BRKIN, I2C0_SDA.
21 PA11 bidirectional General-purpose I/O PA11. 5 V tolerant. Alternate: USART0_CTS, TIMER0_CH3, CMP_OUT, EVENTOUT, SPI1_IO2, I2C0_SMBA, I2C1_SCL.
22 PA12 bidirectional General-purpose I/O PA12. 5 V tolerant. Alternate: USART0_RTS, TIMER0_ETI, EVENTOUT, SPI1_IO3, I2C0_TXFRAME, I2C1_SDA.
23 PA13 bidirectional General-purpose I/O PA13, default assigned to SWDIO (Serial Wire Debug data). 5 V tolerant. Alternate: SWDIO, IFRP_OUT, SPI1_MISO.
24 PA14 bidirectional General-purpose I/O PA14, default assigned to SWCLK (Serial Wire Debug clock). 5 V tolerant. Alternate: USART0_TX, USART1_TX, SWCLK, SPI1_MOSI.
25 PA15 bidirectional General-purpose I/O PA15. 5 V tolerant. Alternate: SPI0_NSS, I2S0_WS, USART0_RX, USART1_RX, SPI1_NSS, EVENTOUT.

30 PB7 bidirectional General-purpose I/O PB7. 5 V tolerant. Alternate: I2C0_SDA, USART0_RX, TIMER16_CH0_ON.
31 BOOT0 input Boot mode select input, sampled at reset. Low = boot from main Flash; high = boot from system-memory (built-in bootloader) or SRAM per option bytes. Tie low through a resistor for normal operation.
32 PB8 bidirectional General-purpose I/O PB8. 5 V tolerant. Alternate: I2C0_SCL, TIMER15_CH0.
33 EPAD/VSS power_in Exposed thermal die pad on the QFN32 underside - combined VSS / VSSA return. Solder to the PCB ground plane for electrical return and heat dissipation; the QFN32 pinout figure labels this pad 'VSS, VSSA' because there are no separate VSS pins in the 32 numbered leads.
