X9C102SIZT1

Overview

The X9C102SIZT1 is a digitally controlled potentiometer (XDCP) from the X9C10 series, manufactured by Renesas Electronics. It features a single channel with a total resistance of 1 kΩ and a linear taper. The device includes 100 taps for precise adjustment and utilizes non-volatile memory to retain wiper position data across power cycles. It operates on a single 5 V supply with a voltage range of 4.5 V to 5.5 V and consumes approximately 1 mA of current. The component is housed in an SOIC-8 surface-mount package and supports a three-wire serial interface for control.

Feature Summary

• Non-volatile memory retains wiper settings after power loss
• 100-tap resolution with 1 kΩ linear resistance
• Three-wire serial interface (CS, U/D, INC)
• SOIC-8 surface-mount packaging

Applications

• Signal processing parameter adjustment
• Control system variable resistance
• Audio volume or tone control circuits

Procurement Notes

Verify the specific suffix 'T1' against official datasheets to confirm reel packaging specifications. Ensure compatibility with standard SOIC-8 footprints during PCB layout. Confirm RoHS compliance status through current manufacturer documentation.

Selection Notes

Select this model for applications requiring 1 kΩ resistance with linear characteristics. The 100-tap configuration offers sufficient resolution for many analog control tasks. Verify that the 3-wire interface aligns with the host microcontroller's available GPIO pins.

Part Context

This component belongs to the X9C10 family of EEPROM-based digital potentiometers. It shares architectural similarities with the X9C103 and X9C104, differing primarily in total resistance values. The SMT variant (SIZ) replaces older PDIP packages for modern surface-mount assembly requirements.

Replacement Considerations

Direct substitutes within the same family include X9C102SIZ for tube packaging. Other resistance variants like X9C103SIZ or X9C104SIZ are pin-compatible but offer different resistance values.
