X9313WM

Digital Potentiometers Overview

The X9313WM is a single-channel digital potentiometer IC manufactured by Renesas Electronics Corporation. It features a total resistance of 10 kOhms with a linear taper and 32 adjustable taps. The device utilizes non-volatile memory to retain the wiper position upon power loss. It operates on a 5V supply voltage within an industrial temperature range of 0°C to 70°C. The component is housed in an 8-MSOP surface-mount package and communicates via a serial interface using Up/Down, Increment, and Chip Select signals. This specific part number is classified as obsolete and no longer in production.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper settings after power cycles
• Linear taper with 32 discrete tap positions
• Serial control interface (Up/Down, Inc, CS)
• Single circuit configuration in 8-MSOP package

Digital Potentiometers Applications

• Volume control in audio equipment
• Gain adjustment in signal conditioning circuits
• Voltage reference setting in measurement systems

Digital Potentiometers Procurement Notes

The X9313WM is officially discontinued and marked as obsolete by the manufacturer. Procurement is limited to existing stock from distributors or secondary market sources. Buyers should verify the authenticity of available units and check for RoHS compliance status, as original runs may not meet current environmental standards. Lead times are variable and dependent on remaining inventory levels.

Digital Potentiometers Selection Notes

Designers requiring this component must account for its obsolete status and potential supply chain constraints. For new designs, consider the X9313WMZ as a direct replacement which offers similar specifications but may have updated manufacturing processes. Verify that the 10kOhm resistance and 32-tap resolution meet the application requirements before substituting with other digital potentiometer models.

Digital Potentiometers Part Context

The X9313WM belongs to the XDCP series of digital potentiometers from Renesas. It is functionally equivalent to the X9313 family, differing primarily in packaging and suffix designations. The 'WM' suffix indicates the 8-MSOP package variant. This component was widely used in applications requiring programmable resistance without mechanical wear.

Digital Potentiometers Replacement Considerations

The X9313WMZ is listed as a direct substitute for the X9313WM. Both parts share identical electrical characteristics, pinouts, and functionality. The primary difference lies in the manufacturing revision and potentially RoHS compliance status. Engineers should confirm pin compatibility and software interface compatibility when migrating from the obsolete WM version to the Z version.
