Microchip Tech · Pre-ordered MCUs · TSSOP-14
MCP41HV51-503E from Microchip Tech, in a TSSOP-14. 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 | VL | power_in | Positive digital power supply input relative to DGND, ranging from 1.8V to 5.5V, with a decoupling capacitor to DGND recommended. |
| 2 | SCK | input | SPI serial clock input (Schmitt Trigger); the device is an SPI slave so this pin is input-only. |
| 3 | CS | input | SPI chip select input (Schmitt Trigger); forcing CS to VIL enables the serial commands. |
| 4 | SDI | input | SPI serial data in pin (Schmitt Trigger), connected to the host controller's SDO pin. |
| 5 | SDO | output | SPI serial data out pin, used to read the wiper and TCON registers or monitor the command error bit. |
| 6 | WLAT | input | Wiper latch enable (Schmitt Trigger): 0 = received SPIBUF value is transferred to the wiper register, 1 = received SPI data is held in SPIBUF. |
| 7 | SHDN | input | Shutdown input (Schmitt Trigger) that forces the resistor network terminals into the hardware shutdown state. |
| 8 | NC | unconnected | Not internally connected to the die; to reduce noise coupling, connect to either DGND or VL. |
| 9 | DGND | power_in | Digital ground reference of the device. |
| 10 | V- | power_in | Analog negative potential supply; must not have a higher potential than the DGND pin. |
| 11 | P0B | passive | Potentiometer 0 Terminal B, the fixed connection to the zero-scale wiper value (0x00); voltage must be between V+ and V-. |
| 12 | P0W | passive | Potentiometer 0 wiper terminal, the adjustable terminal; voltage must be between V+ and V-. |
| 13 | P0A | passive | Potentiometer 0 Terminal A, the fixed connection to the full-scale wiper value (0xFF for 8-bit); voltage must be between V+ and V-. |
| 14 | V+ | power_in | Analog positive potential supply; must have a higher potential than the V- pin. |
