X9C104SIZT1

Overview

The X9C104SIZT1 is a single-channel digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics. It features a 100 kΩ end-to-end resistance with a linear taper and 100 tap points for wiper positioning. The device operates on a single 5 V supply, drawing approximately 1 mA during operation. It utilizes a non-volatile memory architecture to retain the wiper position after power loss, recalling it upon power-up. The component is housed in an 8-lead SOIC surface-mount package and supports a three-wire serial interface for control.

Feature Summary

• Non-volatile storage of wiper position with power-on recall capability
• Three-wire serial interface (CS, U/D, INC) for digital control
• 100 kΩ resistance value with linear taper and ±20% tolerance
• Single channel configuration with 100 resistive taps

Applications

• Signal processing parameter adjustment
• Control circuit gain setting
• Voltage reference trimming

Procurement Notes

Verify the specific suffix 'IZT1' against the manufacturer's current datasheet to confirm availability status and RoHS compliance details. Ensure the ordering quantity matches the factory reel size of 2500 units or cut tape options if applicable. Confirm the industrial temperature range (-40°C to +85°C) meets the design requirements before procurement.

Selection Notes

Select this component when a 100 kΩ digital potentiometer with non-volatile memory retention is required. The 100-tap resolution provides sufficient granularity for many analog control applications. Verify that the system voltage aligns with the 4.5 V to 5.5 V operating range and that the PCB layout accommodates the SOIC-8 package dimensions.

Part Context

This part belongs to the X9C10 series of digitally controlled potentiometers from Renesas/Intersil. The series includes variants with different resistance values such as X9C102 (1 kΩ) and X9C103 (10 kΩ). All members share similar architectural features including the non-volatile memory and three-wire interface, differing primarily in total resistance and temperature coefficient specifications.

Replacement Considerations

The X9C104SZT1 is identified as a direct replacement for the obsolete X9C104ST1 variant within the same family. Cross-referencing with other manufacturers requires verifying pin compatibility and electrical parameters such as wiper resistance and supply voltage ranges.
