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 | PD4 | bidirectional | General-purpose I/O port D bit 4. Default function after reset is PD4 GPIO; AF0 alternate function is I2C1_SMBA. |+| 2 | PD5/SWDIO/AIN0 | bidirectional | Muxed pin: default after power-on is SWDIO (Serial Wire Debug data). Also usable as PD5 GPIO or ADC analog input AIN0. AF0 alternate is SWDIO. |+| 3 | PD6/AIN1 | bidirectional | GPIO port D bit 6, also selectable as ADC analog input AIN1. No AF0 alternate. |+| 4 | NRST | input | Active-low device reset input. Bidirectional in that internal reset events also drive this pin low; external pull-up recommended. |+| 5 | PA1/HSECLK1 | bidirectional | GPIO port A bit 1; can also be configured as external high-speed clock input HSECLK1 (1-32 MHz). |+| 6 | PA2 | bidirectional | GPIO port A bit 2. AF0 alternate function is I2C1_SMBA. |+| 7 | VSS/VSSA | power_in | Combined digital and analog ground. VSS and VSSA are bonded together on-chip; connect to system ground. |+| 8 | VCAP | passive | Internal LDO output / decoupling node. Datasheet notes 'NC, Floating' for this variant - leave unconnected (no external cap required per this table). |+| 9 | VDD/VDDA | power_in | Combined digital and analog supply. VDD and VDDA are bonded together on-chip; supply within recommended operating range (typ. 2.0-5.5 V) with local decoupling. |+| 10 | PA3 | bidirectional | GPIO port A bit 3. No AF0 alternate function. |+| 11 | PB5/SWCLK/HSECLK3 | bidirectional | Muxed pin: default after reset is SWCLK (Serial Wire Debug clock). Alternatively PB5 GPIO, HSE clock input HSECLK3, or I2C1_SDA via additional register selection. |+| 12 | PB4 | bidirectional | GPIO port B bit 4. AF0 alternate function is I2C1_SCL. |+| 13 | PC3 | bidirectional | GPIO port C bit 3. No AF0 alternate function. |+| 14 | PC4/AIN2 | bidirectional | GPIO port C bit 4, also selectable as ADC analog input AIN2. |+| 15 | PC5/HSECLK4 | bidirectional | GPIO port C bit 5; can also serve as HSE clock input HSECLK4. AF0 alternate function is I2C1_SDA. |+| 16 | PC6 | bidirectional | GPIO port C bit 6. AF0 alternate function is I2C1_SCL. |+| 17 | PC7 | bidirectional | GPIO port C bit 7. No AF0 alternate function. |+| 18 | PD1 | bidirectional | GPIO port D bit 1. AF0 alternate function is I2C1_SMBA. |+| 19 | PD2/AIN4 | bidirectional | GPIO port D bit 2, also selectable as ADC analog input AIN4. |+| 20 | PD3/AIN3 | bidirectional | GPIO port D bit 3, also selectable as ADC analog input AIN3. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HK |+| Package | TSSOP-20 |+| Category | MCU |+| Pins | 20 |++## Ordering variants++- `HK32F030MF4P6`+- `HK32F030MF4P6HK32F030MF4U6`+- `HK32F030MF4P6HK32F030MD4P6`+- `HK32F030MF4P6HK32F030MJ4M6`++## CAD (KiCad official)++- Symbol: `HK32F030MF4P6`+- 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:** [HK datasheet](docs/hk32f030mf4p6-datasheet.pdf) (50 pp, sha256 `cbd107b3967444b1`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
