X9313WMI

Digital Potentiometers Overview

The X9313WMI is a single-channel digital potentiometer IC manufactured by Renesas Electronics Corporation. It features a total resistance of 10 kOhms with 32 taps and linear taper characteristics. The device utilizes non-volatile memory to retain wiper position data upon power loss. It operates on a 5V supply voltage and communicates via a 3-wire serial interface (U/D, INC, CS). Packaged in an 8-MSOP surface-mount format, it supports an industrial temperature range of -40°C to +85°C. The component has a typical contact resistance of 40 Ohms and a tolerance of ±20%.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper settings without external power
• 3-wire serial interface for simplified control connections
• Linear resistance taper with 32 discrete tap positions
• Single channel configuration in compact 8-MSOP package

Digital Potentiometers Applications

• Audio volume control circuits requiring adjustable gain
• Programmable voltage reference generation
• Sensor calibration and offset adjustment systems
• Variable gain amplifier configurations

Digital Potentiometers Procurement Notes

The X9313WMI is classified as obsolete and no longer manufactured by Renesas Electronics Corporation. Verification of current stock availability through authorized distributors is required before procurement planning. Designers should consider the direct replacement part number X9313WMIZ for new implementations to ensure RoHS compliance and long-term supply stability.

Digital Potentiometers Selection Notes

Select this component when a single-channel, non-volatile digital potentiometer with 10kOhm resistance is required. Ensure the application supports the 5V operating voltage and 3-wire serial interface protocol. Verify that the 8-MSOP package dimensions fit the PCB layout constraints. Confirm that the ±20% resistance tolerance meets the circuit accuracy requirements.

Digital Potentiometers Part Context

The X9313WMI belongs to the XDCP™ series of digital potentiometers from Renesas. This series integrates EEPROM technology to provide non-volatile storage for wiper positions. The 'W' suffix indicates the MSOP package type, while 'M' denotes the industrial temperature grade. It serves as a solid-state alternative to mechanical potentiometers in space-constrained designs.

Digital Potentiometers Replacement Considerations

The X9313WMIZ is listed as a direct replacement for the X9313WMI. Both parts share identical electrical specifications and pinouts. The primary difference is that the Z suffix variant complies with RoHS standards, whereas the WMI version does not.
