X9C104SI

Overview

The X9C104SI is a non-volatile digital potentiometer from the X9C10 series manufactured by Renesas Electronics. It features a single channel with a total resistance of 100 kΩ and a linear taper. The device utilizes a 3-wire serial interface (CS, U/D, INC) to control the wiper position across 100 taps. It operates on a single 5V supply voltage and includes non-volatile memory to retain the wiper setting after power loss. The component is housed in an 8-pin SOIC package.

Feature Summary

• Non-volatile memory retains wiper position upon power-up
• 100-tap resolution with linear resistance taper
• Single-channel 100 kΩ resistance option
• 3-wire serial interface for up/down control

Applications

• Signal processing parameter adjustment
• Control system variable resistance
• Audio equipment gain settings

Procurement Notes

Verify the specific suffix 'SI' against the manufacturer's official datasheet to confirm the exact temperature range and packaging variant. Ensure compatibility with the required operating environment before procurement.

Selection Notes

Select this model when a 100 kΩ linear digital potentiometer with non-volatile storage is required. Confirm that the 5V single-supply operation and 3-wire interface align with the system design constraints.

Part Context

This component belongs to the X9C10 family of digitally controlled potentiometers (XDCP). Other members include X9C102, X9C103, and X9C503, which offer different resistance values but share similar architectural features and interface protocols.

Replacement Considerations

Cross-reference with X9C104SZ or X9C104SIZT1 for equivalent functionality. Verify pinout and electrical specifications match exactly before substitution.
