X9317ZM8I-2.7T1

Digital Potentiometers Overview

The X9317ZM8I-2.7T1 is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features a single potentiometer with 100 tap positions and a resistance value of 10 kOhms. The device utilizes nonvolatile memory to retain the wiper position during power-off conditions. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an industrial temperature range from -40 °C to +85 °C. The component is housed in an 8-pin MSOP package and communicates via a 3-wire increment/decrement interface.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position upon power-up

Digital Potentiometers Procurement Notes

Verify the specific suffix '2.7' against official Renesas documentation to confirm the minimum operating voltage rating and any associated electrical characteristics. Confirm the package type corresponds to the MSOP-8 form factor as indicated by the 'M8' designation in the part number structure. Ensure compatibility with the intended PCB footprint before procurement.

Digital Potentiometers Selection Notes

Select this component when a low-power, nonvolatile digital potentiometer with 100 taps is required. The 10 kOhm resistance value suits applications requiring moderate impedance levels. Verify that the 3-wire serial interface aligns with the microcontroller or controller available in the design. Consider the MSOP-8 package constraints for space-limited designs.

Digital Potentiometers Part Context

This part belongs to the X9317 series of low noise, low power digitally controlled potentiometers. The series typically offers various resistance values and package options. The X9317 family is characterized by its use of CMOS technology and nonvolatile storage, allowing for persistent settings without continuous power.

Digital Potentiometers Replacement Considerations

Direct replacements include other X9317 variants with matching resistance and package, such as X9317WM8IZ. Cross-reference pinouts and electrical specifications carefully when substituting with components from different manufacturers.
