Description and Introduction

Single Digitally Controlled Potentiometer (XDCP?) The part **X93156UM8I-2.7** is a digital potentiometer manufactured by **Intersil** (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Type:** Digitally Controlled Potentiometer (XDCP™)  
- **Taper:** Linear  
- **Resistance Value:** 50 kΩ  
- **Number of Taps:** 256  
- **Interface:** 3-Wire (Up/Down) Serial  
- **Supply Voltage (VCC):** 2.7V to 5.5V  
- **Temperature Range:** -40°C to +85°C  
- **Package:** 8-Lead MSOP (UM8)  
- **Non-Volatile Memory:** Yes (Retains settings during power-off)  
- **End-to-End Resistance Tolerance:** ±20%  
- **Low Power Consumption:** 3 µA (max) standby current  

### **Descriptions:**
- The **X93156UM8I-2.7** is a solid-state potentiometer that replaces mechanical potentiometers in electronic circuits.  
- It provides 256 programmable resistance steps with non-volatile storage, ensuring settings are retained when power is removed.  
- It is designed for applications requiring precision adjustments, such as calibration, offset trimming, and signal conditioning.  

### **Features:**
- **Non-Volatile Wiper Storage:** Saves wiper position when powered off.  
- **Low Power Operation:** Suitable for battery-powered devices.  
- **3-Wire Serial Control:** Simple up/down interface for adjustment.  
- **Small Form Factor:** 8-Lead MSOP package for space-constrained designs.  
- **Wide Operating Voltage:** Supports 2.7V to 5.5V for versatile use.  
- **High Reliability:** Solid-state design eliminates mechanical wear.  

This part is commonly used in **audio equipment, instrumentation, industrial controls, and programmable voltage dividers**.  

(Note: Always refer to the latest datasheet from Renesas/Intersil for detailed technical information.)

Application Scenarios & Design Considerations

Single Digitally Controlled Potentiometer (XDCP?)

Alternative Part Number

  • ISL23315TFUZ --: Single-channel 32-tap I2C digital potentiometer from the ISL23315 series, the direct successor family to the X93156, with similar 2.7V operation and MSOP-8 package.
  • AD5241BRZ10 --: I2C-compatible 256-position digital potentiometer offering comparable functionality and low-voltage operation, suitable as a cross-vendor replacement.
  • MCP4017T-103E/LT --: Single I2C digital potentiometer with 128 taps in a small SC-70 package, a widely available alternative for low-voltage trim applications.
