X9C102SIT2

Overview

The X9C102SIT2 is a non-volatile digital potentiometer from the XDCP series, manufactured by Renesas Electronics. It features a single circuit with 100 wiper tap points and a total resistance of 1 kΩ. The device utilizes a linear taper and operates via a 3-wire serial interface (Up/Down, Increment, Chip Select). Powered by a single 5V supply, it stores wiper positions in EEPROM for recall upon power-up. Packaged in an 8-SOIC surface-mount format, it supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Non-volatile memory retains wiper position data without external power
• 100 discrete tap points with ±20% end-to-end resistance tolerance
• 3-wire serial control interface for simple microcontroller integration
• CMOS technology with low active current consumption

Applications

• Signal processing parameter adjustment
• Hardware gain control circuits
• Sensor calibration systems
• Audio volume or tone control applications

Procurement Notes

Verify component status as sources indicate this specific SOIC tape-and-reel variant may be discontinued. Confirm availability through authorized distributors and check for alternative packaging options such as tube versions if current stock is insufficient.

Selection Notes

Select this model for applications requiring precise, programmable resistance values that must persist across power cycles. Ensure the 1 kΩ resistance and linear taper align with circuit requirements. Verify that the 3-wire interface logic levels are compatible with the controlling microcontroller.

Part Context

This component belongs to the X9C102 family, which includes variants with different resistance values (e.g., X9C103 for 10 kΩ, X9C104 for 100 kΩ) and package types. The Suffix 'T2' denotes the 8-SOIC tape and reel packaging configuration.

Replacement Considerations

Publicly confirmed substitute part numbers were not identified in the provided source material. Consult manufacturer documentation for direct pin-compatible alternatives within the same product family.
