Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | HVC/A0 | input | High-voltage-tolerant (up to 12.5V) Schmitt-trigger input that serves as I2C Address 0, latched at POR/BOR, and as the High Voltage Command pin when driven to VIHH. |

| 3 | SDA | bidirectional | I2C serial data input/output with an open-drain N-channel driver and a high-voltage-tolerant Schmitt-trigger input. |
| 4 | VSS | power_in | Ground reference for the device. |
| 5 | P0A | passive | Potentiometer 0 Terminal A, the fixed full-scale connection (wiper code 0x100 for 8-bit); it has no polarity relative to W or B and its voltage must be between VSS and VDD. |
| 6 | P0W | passive | Potentiometer 0 wiper terminal, the adjustable terminal; it has no polarity, supports positive and negative current, and its voltage must be between VSS and VDD. |
| 7 | P0B | passive | Potentiometer 0 Terminal B, the fixed zero-scale connection (wiper code 0x00); it has no polarity, supports positive and negative current, and its voltage must be between VSS and VDD. |
