WMS7170010M

Digital Potentiometers Overview

The WMS7170010M is a single-channel, non-volatile digital potentiometer manufactured by Winbond Electronics Corporation. It features a 10 kΩ end-to-end resistance with 100 linear taps and operates on a single supply voltage ranging from 2.7 V to 5.5 V. The device utilizes an Up/Down (3-wire) serial interface consisting of CS, INC, and U/D signals for wiper control. It includes one non-volatile memory location (NVMEM0) that automatically recalls the wiper position upon power-up. The component supports industrial operating temperatures from -40°C to +85°C and offers data retention of 100 years with an endurance of 100,000 write cycles.

• Single channel with 100-tap resolution and 10 kΩ nominal resistance
• Non-volatile memory (NVMEM0) for automatic wiper recall at power-on
• Up/Down (3-wire) serial interface for wiper positioning
• Industrial temperature range (-40°C to +85°C) and 2.7V to 5.5V operation

Digital Potentiometers Applications

• Programmable inverting gain amplifiers
• Programmable non-inverting gain amplifiers
• Voltage reference trimming circuits
• RF amplifier control systems

Digital Potentiometers Procurement Notes

Verify the manufacturer designation as Winbond Electronics Corporation despite the Nuvoton brand input. Confirm the specific package type (SOIC, PDIP, or MSOP) required for the application, as the datasheet lists multiple packaging options for this part number series. Ensure compatibility with the 3-wire serial interface timing requirements during integration.

Digital Potentiometers Selection Notes

Select the WMS7170 variant if a two-terminal variable resistor or three-terminal voltage divider without an output buffer is needed. Choose the WMS7171 variant only if an integrated output buffer is required for voltage divider configurations. Verify that the 10 kΩ resistance value aligns with the circuit's impedance requirements and that the 100-tap resolution meets the necessary adjustment granularity.

Digital Potentiometers Part Context

This component belongs to the WinPot family of non-volatile digital potentiometers featuring an Up/Down interface. The '010' suffix indicates a 10 kΩ resistance value, while the 'M' suffix denotes the MSOP package option. The device is designed as a drop-in replacement for various legacy analog potentiometers in embedded systems requiring programmable resistance adjustments.

Digital Potentiometers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should evaluate other 100-tap non-volatile digital potentiometers with compatible 3-wire interfaces and similar electrical characteristics if direct replacements are necessary.
