HC89S003AF4U7M from Shanghai Holychip Elec, 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 | P0.1 | bidirectional | General I/O port P0.1, also ADC channel 1 input (AN1), external interrupt 1 (INT1) and PWM1 fault-detection input (FLT1); the port is configurable as input, pull-up/pull-down input, Schmitt input, analog, push-pull or open-drain output. |
| 2 | P0.0 | bidirectional | General I/O port P0.0, also ADC channel 0 input (AN0), external interrupt 0 (INT0) and PWM0 fault-detection input (FLT0), whose debounce is set by the P00DBC register. |
| 3 | GND | power_in | Ground (power supply ground); the datasheet requires a capacitor of at least 0.1 µF between VDD and GND for system stability. |
| 4 | P1.0 | bidirectional | General I/O port P1.0, also external crystal input XIN, software-selectable external interrupt 0 (INT0_1) and comparator 2 positive input (CMP2+). |
| 5 | VDD | power_in | Power supply input, operating range 2.0 V to 5.5 V; the exposed pad under the package is connected to this pin. |

| 7 | P2.7 | bidirectional | General I/O port P2.7, also external reset input RST (factory default, Schmitt input with pull-up), external interrupt 15 (INT15) and ADC channel 15 (AN15); it cannot be used as GPIO while configured as RST. |
| 8 | P2.6 | bidirectional | General I/O port P2.6, also JTAG TMS input, external interrupt 14 (INT14), ADC channel 14 (AN14), port low-voltage detection input PLVD (1.2 V threshold) and comparator negative input (CMP-). |
| 9 | P2.5 | bidirectional | General I/O port P2.5, also JTAG TCK input, external interrupt 13 (INT13), ADC channel 13 (AN13) and comparator 1 positive input (CMP1+). |
| 10 | P2.4 | bidirectional | General I/O port P2.4, also JTAG TDO data output, external interrupt 12 (INT12) and ADC channel 12 (AN12). |
| 11 | P2.3 | bidirectional | General I/O port P2.3, also JTAG TDI data input, external interrupt 11 (INT11) and ADC channel 11 (AN11). |
| 12 | P2.1 | bidirectional | General I/O port P2.1, also ADC channel 9 input (AN9), external interrupt 9 (INT9) and two-wire IIC data line SDA. |
| 13 | P2.2 | bidirectional | General I/O port P2.2, also ADC channel 10 input (AN10) and external interrupt 10 (INT10). |
| 14 | P2.0 | bidirectional | General I/O port P2.0, also ADC channel 8 input (AN8) and external interrupt 8 (INT8). |
| 15 | P0.7 | bidirectional | General I/O port P0.7, also ADC channel 7 input (AN7) and external interrupt 7 (INT7). |
| 16 | P0.6 | bidirectional | General I/O port P0.6, also ADC channel 6 input (AN6) and external interrupt 6 (INT6). |
| 17 | P0.5 | bidirectional | General I/O port P0.5, also ADC channel 5 input (AN5) and external interrupt 5 (INT5). |
| 18 | P0.4 | bidirectional | General I/O port P0.4, also ADC channel 4 input (AN4), ADC external reference voltage input/output Vref (must be analog input when used) and external interrupt 4 (INT4). |
| 19 | P0.3 | bidirectional | General I/O port P0.3, also ADC channel 3 input (AN3), external interrupt 3 (INT3) and two-wire mode clock input SCK. |
| 20 | P0.2 | bidirectional | General I/O port P0.2, also ADC channel 2 input (AN2), external interrupt 2 (INT2) and PWM2 fault-detection input (FLT2). |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
