X9C102PZ

Overview

The X9C102PZ is a non-volatile digital potentiometer from the X9C10 series manufactured by Renesas Electronics. It features a single channel with a resistance value of 1 kΩ and 100 tap positions. The device utilizes a linear taper and operates on a single 5V supply voltage. Control is managed via a serial 3-wire interface, allowing wiper position adjustment through CS, U/D, and INC inputs. The component is housed in an 8-pin PDIP package designed for through-hole mounting.

Feature Summary

• Non-volatile memory retains wiper position after power loss
• 100 discrete tap positions with linear resistance taper
• Serial 3-wire control interface (CS, U/D, INC)
• Single-channel configuration with 1 kΩ total resistance

Applications

• Signal processing parameter adjustment
• Control circuit variable resistance
• Hardware gain or offset calibration

Procurement Notes

Verify the specific suffix 'PZ' to confirm the PDIP package type and through-hole installation requirement. Ensure the design supports the specified 5V single supply voltage range. Confirm that the 3-wire serial interface logic levels are compatible with the host controller. Check for RoHS compliance status if environmental regulations apply to the assembly.

Selection Notes

Select this model when a through-hole solution is required for a 1 kΩ digital potentiometer. The 100-tap resolution suits applications needing moderate precision without analog wear. Verify that the ±600 ppm/°C temperature coefficient meets the thermal stability requirements of the target environment. Ensure the PCB layout accommodates the physical dimensions of the 8-pin DIP package.

Part Context

The X9C102PZ belongs to the X9C10 family of digitally controlled potentiometers. This series integrates a resistor array, wiper switching network, control logic, and EEPROM into a single CMOS device. The PZ suffix specifically denotes the plastic dual in-line package variant, distinguishing it from surface-mount options like SOIC or TSSOP within the same electrical specification set.

Replacement Considerations

Cross-reference with other X9C102 variants such as X9C102SZ (SOIC) or X9C102SIZ (PDIP) if pin compatibility differs. Verify that substitute components maintain the same 1 kΩ resistance, 100 taps, and 3-wire interface protocol. Ensure the replacement part supports the required operating temperature range and supply voltage specifications.
