X9317ZV8I

Digital Potentiometers Overview

The X9317ZV8I is a digitally controlled potentiometer (XDCP) from the X9317 series, manufactured by Renesas Electronics. It features a single potentiometer with 100 tap points and a total end-to-end resistance of 1 kOhm. The device utilizes a linear taper and operates on a 5V supply voltage, with a minimum operating current of 50 uA. It employs a nonvolatile memory to store wiper positions, ensuring data retention for up to 100 years. The component supports a 3-wire serial interface for control and functions within an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position upon power-up
• 100 tap points with linear taper for precise control
• Low power CMOS technology with 50 uA operating current
• Industrial temperature range (-40°C to +85°C)

Digital Potentiometers Applications

• Voltage control circuits requiring digital adjustment
• Current control applications using variable resistance
• System calibration where persistent settings are required

Digital Potentiometers Procurement Notes

Verify the specific suffix 'I' against official Renesas documentation to confirm the extended industrial temperature rating (-40°C to +85°C). Confirm RoHS compliance status as some variants in this family may differ. Check for obsolete status or lifecycle notices from the manufacturer before finalizing procurement plans.

Digital Potentiometers Selection Notes

Select the X9317ZV8I when a 1 kOhm resistance value is required alongside nonvolatile storage capabilities. Ensure the design accommodates the 3-wire serial interface (CS, U/D, INC). Compare against other resistance options like 10k or 50k if the system impedance requirements differ. Verify package compatibility with the TSSOP-8 footprint.

Digital Potentiometers Part Context

This component belongs to the X9317 family of Digitally Controlled Potentiometers. It shares core architectural features with siblings such as the X9317UV8IZ and X9317WS8ZT1, differing primarily in resistance value and packaging. The 'Z' suffix typically indicates lead-free/RoHS compliant construction, while 'V' denotes the TSSOP package.

Digital Potentiometers Replacement Considerations

Direct replacements include other X9317 variants with matching 1k resistance and TSSOP-8 packages, such as X9317ZV8IT1. Verify pinout compatibility and electrical specifications before substitution.
