GD32E230F4P6TR from GigaDevice Semicon Beijing, in a TSSOP-20. 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	BOOT0	input	Boot-mode select input, sampled after reset to choose main flash or system memory boot.
2	PF0/OSCIN	bidirectional	General-purpose I/O port F bit 0 (5 V tolerant). Alternate: I2C0_SDA. Additional: HXTAL oscillator input (OSCIN).
3	PF1/OSCOUT	bidirectional	General-purpose I/O port F bit 1 (5 V tolerant). Alternate: I2C0_SCL. Additional: HXTAL oscillator output (OSCOUT).
4	NRST	bidirectional	Bidirectional active-low device reset. Internally pulled up; can be driven low externally to reset the MCU.
5	VDDA	power_in	Analog supply rail for ADC, comparators and reset block. 2.6 V-3.6 V; must be tied to VDD when analog blocks are used.
6	PA0-WKUP	bidirectional	GPIO PA0 with wake-up capability. Alternate: USART0_CTS, USART1_CTS, CMP_OUT, I2C1_SCL. Additional: ADC_IN0, CMP_IM6, RTC_TAMP1, WKUP0.
7	PA1	bidirectional	GPIO PA1. Alternate: USART0_RTS/DE, USART1_RTS/DE, I2C1_SDA, EVENTOUT. Additional: ADC_IN1, CMP_IP.
8	PA2	bidirectional	GPIO PA2. Alternate: USART0_TX, USART1_TX. Additional: ADC_IN2, CMP_IM7.
9	PA3	bidirectional	GPIO PA3. Alternate: USART0_RX, USART1_RX. Additional: ADC_IN3.
10	PA4	bidirectional	GPIO PA4. Alternate: SPI0_NSS, I2S0_WS, USART0_CK, USART1_CK, TIMER13_CH0, SPI1_NSS. Additional: ADC_IN4, CMP_IM4.
11	PA5	bidirectional	GPIO PA5. Alternate: SPI0_SCK, I2S0_CK. Additional: ADC_IN5, CMP_IM5.
12	PA6	bidirectional	GPIO PA6. Alternate: SPI0_MISO, I2S0_MCK, TIMER2_CH0, TIMER0_BRKIN, TIMER15_CH0, EVENTOUT, CMP_OUT. Additional: ADC_IN6.
13	PA7	bidirectional	GPIO PA7. Alternate: SPI0_MOSI, I2S0_SD, TIMER2_CH1, TIMER13_CH0, TIMER0_CH0_ON, TIMER16_CH0, EVENTOUT. Additional: ADC_IN7.
14	PB1	bidirectional	GPIO PB1. Alternate: TIMER2_CH3, TIMER13_CH0, TIMER0_CH2_ON, SPI1_SCK. Additional: ADC_IN9.
15	VSS	power_in	Digital and analog ground reference (VSS/VSSA are internally shared on this package).
16	VDD	power_in	Main digital supply, 2.6 V-3.6 V. Requires a 100 nF decoupling capacitor to VSS.
17	PA9	bidirectional	GPIO PA9 (5 V tolerant). Alternate: USART0_TX, TIMER0_CH1, I2C0_SCL, CK_OUT. Can be remapped to PA11 via SYSCFG_CFG0.
18	PA10	bidirectional	GPIO PA10 (5 V tolerant). Alternate: USART0_RX, TIMER0_CH2, TIMER16_BRKIN, I2C0_SDA. Can be remapped to PA12 via SYSCFG_CFG0.
19	PA13/SWDIO	bidirectional	GPIO PA13 (5 V tolerant); after reset serves as Serial Wire Debug data (SWDIO). Alternate: SWDIO, IFRP_OUT, SPI1_MISO.
20	PA14/SWCLK	bidirectional	GPIO PA14 (5 V tolerant); after reset serves as Serial Wire Debug clock (SWCLK). Alternate: USART0_TX, USART1_TX, SWCLK, SPI1_MOSI.
