MCP41050-I from Microchip Tech, in a SOIC-8. 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 | CS | input | Chip select (CS) SPI input pin with Schmitt Trigger input used to enable command execution after the 16-bit shift register is loaded. |
| 2 | SCK | input | Serial clock (SCK) SPI input pin with Schmitt Trigger input that clocks data into SI on rising edge and out SO on falling edge; operation gated to CS pin. |
| 3 | SI | input | Serial data input (SI) SPI pin with Schmitt Trigger input for clocking command and data bytes into the 16-bit shift register; operation gated to CS pin. |
| 4 | VSS | power_in | Ground (0V) reference voltage for analog and digital circuits. |
| 5 | PA0 | passive | Potentiometer 0 terminal A with voltage range 0V to VDD and no polarity restrictions relative to terminals B and W. |
| 6 | PW0 | passive | Potentiometer 0 wiper terminal with voltage range 0V to VDD and wiper resistance 125-175Ω at VDD = 5.5V, IW = 1mA, code 00h. |
| 7 | PB0 | passive | Potentiometer 0 terminal B with voltage range 0V to VDD and no polarity restrictions relative to terminals A and W. |
| 8 | VDD | power_in | Positive power supply voltage with operating range 2.7V to 5.5V. |
