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.
