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 selection input. Sampled with BOOT1 (in option bytes) at the rising edge of NRST to select main flash, system memory (bootloader), or SRAM as the boot source. |+| 2 | PF0-OSCIN | bidirectional | Port F bit 0 GPIO, 5 V tolerant. Alternate function CTC_SYNC (clock trim controller sync input); can also serve as HXTAL crystal input (OSCIN) when the external oscillator is enabled. |+| 3 | PF1-OSCOUT | bidirectional | Port F bit 1 GPIO, 5 V tolerant. Additional function OSCOUT (HXTAL crystal output) when the external oscillator is enabled. |+| 4 | NRST | bidirectional | Active-low device reset. Bidirectional pin: internal reset sources drive it low, and an external pull-down asserts a system reset. Internal weak pull-up is present; external RC to VDD recommended. |+| 5 | VDDA | power_in | Analog power supply for the ADC, reset block, PLL, and internal oscillators. Must be tied to VDD (2.6-3.6 V) with proper decoupling; VSSA is shared with VSS in this package. |+| 6 | PA0-WKUP | bidirectional | Port A bit 0 GPIO. Muxed alternates: USART1_CTS, I2C1_SCL. Additional analog/system functions: ADC_IN0, RTC_TAMP1, WKUP0 (deep-sleep wake-up). |+| 7 | PA1 | bidirectional | Port A bit 1 GPIO. Muxed alternates: USART1_RTS, I2C1_SDA, EVENTOUT. Additional analog: ADC_IN1. |+| 8 | PA2 | bidirectional | Port A bit 2 GPIO. Muxed alternates: USART1_TX, TIMER14_CH0. Additional analog: ADC_IN2. |+| 9 | PA3 | bidirectional | Port A bit 3 GPIO. Muxed alternates: USART1_RX, TIMER14_CH1. Additional analog: ADC_IN3. |+| 10 | PA4 | bidirectional | Port A bit 4 GPIO. Muxed alternates: SPI0_NSS, I2S0_WS, USART1_CK, TIMER13_CH0, SPI1_NSS. Additional analog: ADC_IN4. |+| 11 | PA5 | bidirectional | Port A bit 5 GPIO. Muxed alternates: SPI0_SCK, I2S0_CK. Additional analog: ADC_IN5. |+| 12 | PA6 | bidirectional | Port A bit 6 GPIO. Muxed alternates: SPI0_MISO, I2S0_MCK, TIMER2_CH0, TIMER0_BKIN, TIMER15_CH0, EVENTOUT. Additional analog: ADC_IN6. |+| 13 | PA7 | bidirectional | Port A bit 7 GPIO. Muxed alternates: SPI0_MOSI, I2S0_SD, TIMER2_CH1, TIMER13_CH0, TIMER0_CH0_ON, TIMER16_CH0, EVENTOUT. Additional analog: ADC_IN7. |+| 14 | PB1 | bidirectional | Port B bit 1 GPIO. Muxed alternates: TIMER2_CH3, TIMER13_CH0, TIMER0_CH2_ON, SPI1_SCK. Additional analog: ADC_IN9. |+| 15 | VSS | power_in | Device ground reference, 0 V. Also serves as VSSA analog ground on this TSSOP-20 package. |+| 16 | VDD | power_in | Main digital supply, 2.6-3.6 V. Feeds internal 1.2 V LDO for the core. Decouple with 100 nF close to the pin plus a bulk 4.7 uF on the VDD/VDDA rail. |+| 17 | PA9 | bidirectional | Port A bit 9 GPIO, 5 V tolerant. Muxed alternates: USART0_TX, TIMER0_CH1, TIMER14_BKIN, I2C0_SCL. |+| 18 | PA10 | bidirectional | Port A bit 10 GPIO, 5 V tolerant. Muxed alternates: USART0_RX, TIMER0_CH2, TIMER16_BKIN, I2C0_SDA. |+| 19 | PA13 | bidirectional | Port A bit 13 GPIO, 5 V tolerant. Serial Wire Debug data line (SWDIO) after reset. Muxed alternates: IFRP_OUT (IR modulation output), SPI1_MISO. |+| 20 | PA14 | bidirectional | Port A bit 14 GPIO, 5 V tolerant. Serial Wire Debug clock (SWCLK) after reset. Muxed alternates: USART1_TX, SPI1_MOSI. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | GigaDevice Semicon Beijing |+| Package | TSSOP-20 |+| Category | MCU |+| Pins | 20 |++## Ordering variants++Same part, different packaging or reel option.++- `GD32F310F8P6TRF4P6`+- `GD32F310F8P6TRF6P6`+- `GD32F310F8P6TR`+- `GD32F310F8P6TRG8U6`+- `GD32F310F8P6TRK6T6`+- `GD32F310F8P6TRK8T6`+- `GD32F310F8P6TRK8U6`+- `GD32F310F8P6TRC8T6`++## CAD (KiCad official)++- Symbol: `GD32F310F8P6TR`+- Footprint: `Package_SO:TSSOP-20_4.4x6.5mm_P0.65mm`+- 3D model: TSSOP-20 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [GigaDevice Semicon Beijing datasheet](docs/gd32f310f8p6tr-datasheet.pdf) (78 pp, sha256 `bd7f1b34d0ebdf35`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
