X9317UV8IZ-2.7T1

Digital Potentiometers Overview

The X9317UV8IZ-2.7T1 is a single-channel digital potentiometer from the XDCP series, manufactured by Renesas Electronics Corporation. It features a total end-to-end resistance of 50 kOhms with a linear taper and offers 100 discrete taps for precise resistance adjustment. The device utilizes nonvolatile memory to retain wiper position data upon power cycling. It operates within a supply voltage range of 2.7V to 5.5V and communicates via a three-wire serial interface consisting of Up/Down (U/D), Increment (INC), and Chip Select (CS) signals. The component is housed in an 8-TSSOP surface-mount package.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position settings during power-off cycles
• Linear taper configuration with 100 adjustable taps
• Three-wire serial interface (U/D, INC, CS) for control
• Operates on supply voltages between 2.7V and 5.5V

Digital Potentiometers Applications

• Digitally controlled resistance trimming in electronic circuits
• Parameter adjustments requiring persistent setting storage
• Signal processing applications needing variable resistance

Digital Potentiometers Procurement Notes

Verify RoHS compliance status as documentation indicates potential variations across specific manufacturing lots or suffixes. Confirm the exact package dimensions against the 8-TSSOP specification sheet prior to PCB layout finalization. Ensure the selected variant matches the required operating temperature range for the target application environment.

Digital Potentiometers Selection Notes

Select this component when a single-channel, nonvolatile digital potentiometer with a 50k Ohm range is required. The 100-tap resolution provides finer granularity compared to devices with fewer steps. Verify that the system logic levels are compatible with the U/D, INC, and CS interface requirements before integration into the design.

Digital Potentiometers Part Context

This part belongs to the X9317 family of digitally controlled potentiometers. Variants within this series typically share core architectural features but differ in resistance values, packaging options, and environmental ratings. The 'IZ' suffix generally denotes industrial temperature range specifications, while 'T1' indicates tape-and-reel packaging for automated assembly processes.

Digital Potentiometers Replacement Considerations

The X9317UV8I-2.7T1 is listed as a direct substitute. Verify pinout compatibility and electrical parameter alignment, specifically the 50k Ohm resistance and 100-tap count, before swapping components in existing designs.
