X95820WV14I-2.7

Overview

The X95820WV14I-2.7 is a single-channel digital potentiometer from the Renesas XDCP series, housed in a 14-TSSOP package. It features a total resistance of 10k ohms with 64 taps and utilizes an SPI interface for control. The device operates on a supply voltage range of 2.7V to 5.5V and includes non-volatile memory to retain wiper position data. It offers selectable address capabilities and maintains a typical wiper resistance of 150 ohms across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates non-volatile memory to preserve wiper settings during power loss
• Supports serial communication via SPI interface for digital control
• Provides selectable address functionality for multi-device bus configurations

Applications

• Parameter adjustment in industrial control systems
• Signal processing circuit tuning
• Embedded system calibration

Procurement Notes

Verify component authenticity through official Renesas channels or authorized distributors due to potential availability constraints. Confirm specific ordering suffixes match required interface and package variants. Check current lifecycle status as components may be subject to discontinuation notices. Ensure environmental compliance requirements align with project specifications before procurement.

Selection Notes

Select this component when a single-channel digital potentiometer with SPI interface and non-volatile storage is required. Consider the 10k ohm resistance value and 64-tap resolution against application needs. Verify that the 14-TSSOP package fits the PCB layout constraints. Ensure the 2.7V to 5.5V supply range matches the system voltage rails.

Part Context

This part belongs to the XDCP family of digitally controlled potentiometers by Renesas Electronics Corporation. These devices combine CMOS technology with resistor arrays and switches to provide precise digital adjustment of analog signals. The series is designed for applications requiring reliable, non-volatile resistance control in compact surface-mount packages.

Replacement Considerations

Consult official Renesas documentation for verified cross-reference part numbers. Do not assume functional equivalence with generic digital potentiometers without verifying interface protocols, pinouts, and electrical characteristics.
