**RENESAS** · Digital Potentiometers · TSSOP-8

X9317WV8Z from RENESAS, in a TSSOP-8. 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 | CS | input | The device is selected when CS is LOW and de-selected when CS is HIGH; the counter value is stored to nonvolatile memory when CS returns HIGH while INC is also HIGH. |
| 2 | VCC | power_in | Supply voltage; the X9317WV8Z is specified for VCC = 5V ±10% (4.5 V to 5.5 V), with absolute input voltage limits of -1 V to +7 V referenced to VSS. |
| 3 | INC | input | INC is negative-edge triggered, and toggling INC while CS is low moves the wiper up or down depending on U/D. |
| 4 | U/D | input | The U/D input controls the direction of the wiper movement and whether the counter is incremented or decremented. |
| 5 | RH | passive | The high terminal is equivalent to one of the fixed terminals of a mechanical potentiometer, with RH/RL terminal voltage limited to VSS to VCC and RH, RW, RL to ground rated at +6 V maximum. |
| 6 | VSS | power_in | Ground reference for the device; all control input voltages are referenced to VSS. |
| 7 | RW | passive | The wiper terminal is equivalent to the movable terminal of a mechanical potentiometer, with wiper current limited to ±4.4 mA. |
| 8 | RL | passive | The low terminal is equivalent to one of the fixed terminals of a mechanical potentiometer, with terminal voltage limited to VSS to VCC. |
