WMS7120010P

Digital Potentiometers Overview

The WMS7120010P is a non-volatile digital potentiometer manufactured by Winbond Electronics Corporation, featuring a 10 kΩ end-to-end resistance and 64 linear taps. It operates on a single supply voltage ranging from 2.7V to 5.5V and utilizes a 3-wire Up/Down serial interface for control. The device includes one non-volatile memory location (NVMEM0) that automatically loads the wiper position upon power-up. Packaged in an 8-pin PDIP format, it supports both rheostat and potentiometer configurations within an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Non-volatile storage with automatic power-on recall
• Single channel with 64 linear taps
• 3-wire Up/Down serial interface
• Industrial temperature range (-40°C to +85°C)

Digital Potentiometers Applications

• Programmable gain amplifiers
• Voltage reference trimming
• RF amplifier control

Digital Potentiometers Procurement Notes

Verify the manufacturer origin, as the datasheet identifies Winbond Electronics Corporation as the producer despite the prompt specifying Nuvoton Technology Corporation. Confirm the package type matches the 'P' suffix for PDIP and ensure the component meets the required industrial temperature specifications.

Digital Potentiometers Selection Notes

Select this component when a non-volatile digital potentiometer with a 10 kΩ resistance value is required. Ensure the application supports the 3-wire Up/Down interface protocol. Verify that the operating voltage falls between 2.7V and 5.5V and that the 64-tap resolution is sufficient for the specific circuit requirements.

Digital Potentiometers Part Context

This part belongs to the WMS712x series of non-volatile digital potentiometers. The '0' in the model number indicates the absence of an output buffer, distinguishing it from the WMS7121 variant which includes a buffered output. The '010' suffix specifies the 10 kΩ resistance value, while 'P' denotes the 8-pin PDIP package.

Digital Potentiometers Replacement Considerations

Compatible replacements include other parts from the WMS712x family, such as the WMS7120050P or WMS7120100P, provided the resistance values align with the design needs. Cross-manufacturer equivalents with matching 3-wire interfaces and non-volatile characteristics should be evaluated based on pin compatibility and electrical parameters.
