X9C103PIZC7644

Overview

The X9C103PIZ is a single-channel, non-volatile digital potentiometer from the X9C10 series manufactured by Renesas Electronics. It features a 10 kΩ linear resistance taper with 100 tap points and operates on a single 5 V supply (4.5 V to 5.5 V). The device utilizes a 3-wire serial interface for control and includes EEPROM memory to retain wiper settings during power loss. Packaged in an 8-pin PDIP format, it supports through-hole mounting and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Non-volatile EEPROM storage retains wiper position after power-off
• 100-tap resolution with 10 kΩ linear resistance
• Simple 3-wire serial interface (CS, U/D, INC)
• Single-supply operation at 5 V with low standby current

Applications

• Volume control in audio circuits
• Programmable gain adjustment for amplifiers
• Offset voltage trimming in signal processing
• Parameter adjustment in industrial control systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Check for end-of-life notices or production change notifications as availability may be restricted.

Selection Notes

Select this component when non-volatile memory retention is required without external backup batteries. Ensure the 10 kΩ resistance value matches circuit requirements. Verify that the 3-wire interface is compatible with the host microcontroller's available GPIO pins.

Part Context

This part belongs to the X9C10 family of digitally controlled potentiometers. Variants such as X9C102, X9C104, and X9C503 share similar architectures but differ in resistance values (2 kΩ, 100 kΩ) or package types. The 'P' suffix indicates a plastic DIP package, while 'IZ' typically denotes specific tape/reel or commercial grade variations.

Replacement Considerations

Direct pin-compatible replacements include X9C102, X9C104, and X9C503 if resistance values are adjustable. For surface-mount needs, consider the SOIC-8 variants like X9C103SZ or X9C103SIZ, ensuring voltage and temperature ratings align.
