Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | HVC/A0 | input | High-voltage command / address bit 0 input with internal 'smart' VDD pull-up; state is latched at POR/BOR; tolerates up to 12.5 V (VIHH) to enable high-voltage serial commands; VIH ≥ 0.45 VDD for VDD 2.7-5.5 V. |
| 2 | SCL | input | I2C serial clock input, slave-only (no clock stretching); supports standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz) modes; VIH ≥ 0.7 VDD. |
| 3 | SDA | bidirectional | I2C serial data open-drain N-channel I/O; SDA must be stable while SCL is HIGH; VOL ≤ 0.4 V at IOL = 3 mA (VDD ≥ 2.0 V). |
| 4 | VSS | power_in | Ground reference; maximum current out of VSS pin is 100 mA. |
| 5 | P1B | passive | Resistor network 1 Terminal B (zero-scale end); voltage range VSS to VDD; maximum terminal current ±2.5 mA; disconnectable via TCON register bit R1B. |
| 6 | P1W | passive | Resistor network 1 wiper (adjustable terminal); wiper resistance typically 75 Ω (max 160 Ω) at VDD = 5.5 V, IW = 2.0 mA, code = 00h; voltage range VSS to VDD. |
| 7 | P0W | passive | Resistor network 0 wiper (adjustable terminal); wiper resistance typically 75 Ω (max 160 Ω) at VDD = 5.5 V, IW = 2.0 mA, code = 00h; voltage range VSS to VDD. |
| 8 | P0B | passive | Resistor network 0 Terminal B (zero-scale end); voltage range VSS to VDD; maximum terminal current ±2.5 mA; disconnectable via TCON register bit R0B. |
| 9 | A1 | input | I2C address bit 1 input with internal 'smart' pull-up; must be tied statically to VDD or VSS; VIH ≥ 0.45 VDD; supports up to 4 MCP46X2 devices on one I2C bus together with A0. |
| 10 | VDD | power_in | Positive power supply input; 2.7 V to 5.5 V for full electrical specifications, 1.8 V to 5.5 V for serial interface operation only; decouple with 0.1 µF to VSS placed within 4 mm of pin. |
| 11 | EP | passive | Exposed thermal pad on bottom of package, conductively connected to die substrate; must be left unconnected or tied to the same potential as VSS; may be used as PCB heat sink connection. |
