HC89F0312-SOP8-T-M

holychip(芯圣电子) · Microcontrollers (MCU/MPU/SOC) · SOP-8-150mil

HC89F0312-SOP8-T-M from holychip(芯圣电子), in a SOP-8-150mil. 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 VDD power_in Power supply input; the datasheet specifies an operating range of 2.9 V to 5.5 V and an absolute maximum of -0.3 V to +6.0 V, and a capacitor of at least 0.1 μF must be connected between VDD and GND for system stability.
2 P2.1 bidirectional General-purpose I/O port pin that also serves as ADC channel AN9, external interrupt INT9 and SDA data input/output in two-wire (SWD/ICP) mode, with software-configurable port modes.
3 P0.4 bidirectional General-purpose I/O port pin that also serves as ADC channel AN4, external interrupt INT4 and the ADC reference Vref pin, which must be set to analog input when used as an external reference input (VREFS = 1) or as the internal VREF output (VREFO = 1).
4 P0.3 bidirectional General-purpose I/O port pin that also serves as ADC channel AN3, external interrupt INT3 and the SCK clock input for two-wire mode.
5 P0.2 bidirectional General-purpose I/O port pin that also serves as ADC channel AN2, external interrupt INT2 and PWM2 fault-detection input FLT2, and can be used as the single-channel ADC wake-up pin from power-saving modes.
6 P0.1 bidirectional General-purpose I/O port pin that also serves as ADC channel AN1, external interrupt INT1 and PWM1 fault-detection input FLT1.
7 P0.0 bidirectional General-purpose I/O port pin that also serves as ADC channel AN0, external interrupt INT0 and PWM0 fault-detection input FLT0, whose debounce time is configurable through P00DBC.
8 GND power_in Ground reference for the device; the datasheet limits the maximum current through GND to 150 mA at 5.0 V and 25 °C.
