X9314WM-3T1

Digital Potentiometers Overview

The X9314WM-3T1 is a single-channel digitally controlled potentiometer (XDCP) from the X9314 series, manufactured by Renesas Electronics. It features a 10 kΩ end-to-end resistance with logarithmic taper and 32 taps. The device utilizes a nonvolatile memory to store wiper positions, allowing recall upon power-up. It operates on a supply voltage range of 3 V to 5.5 V with a maximum standby current of 500 µA. The component interfaces via a three-wire serial protocol (CS, U/D, INC) and is housed in an 8-lead MSOP package.

Digital Potentiometers Feature Summary

• Nonvolatile storage of wiper position for data retention up to 100 years
• Three-wire serial interface (CS, U/D, INC) for digital control
• Logarithmic taper with 32 taps and 10 kΩ total resistance
• Operates within 3 V to 5.5 V supply voltage range

Digital Potentiometers Applications

• Digitally controlled resistance trimming
• Parameter adjustments in signal processing circuits
• Audio volume control applications requiring logarithmic response

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T1' against official Renesas documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status as manufacturing sources may vary between Intersil and Renesas eras. Check for obsolescence notices or lifecycle changes prior to final design approval.

Digital Potentiometers Selection Notes

Select this component when a solid-state solution replacing mechanical potentiometers is required for nonvolatile adjustment. Ensure the circuit design supports the 3-wire serial interface timing requirements. Verify that the 10 kΩ resistance value and logarithmic taper align with the application's signal attenuation needs.

Digital Potentiometers Part Context

This part belongs to the X9314 family of CMOS EEPOTs. It is functionally similar to the X9314WS-3 but differs in package type (MSOP vs SOIC). The 'WM' designation indicates the MSOP-8 package, while 'T1' typically denotes reel packaging. It serves as a direct replacement for legacy Intersil versions in compatible footprints.

Digital Potentiometers Replacement Considerations

The X9314WMIZ-3T1 is a verified equivalent variant within the same series, offering identical electrical characteristics in the same MSOP-8 package. Designers should verify pin compatibility and ensure the substitute maintains the same nonvolatile memory behavior.
