X93154UU8IZ-3T1

Digital Potentiometers Overview

The X93154UU8IZ-3T1 is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features a single potentiometer with 32 wiper tap points and a total resistance of 50 kΩ. The device operates on a 3V ±10% supply voltage, drawing a maximum active current of 250µA and a standby current of 1µA. It utilizes a 3-wire serial interface for control and includes nonvolatile memory to retain the wiper position upon power-up. The component is housed in an 8-lead MSOP package and supports an industrial temperature range from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Low power CMOS technology with 250µA max active current and 1µA max standby current
• Industrial temperature range operation from -40°C to +85°C

Digital Potentiometers Applications

• Bias and Gain Control
• LCD Contrast Adjustment
• Micro-Power LCD Contrast Control
• Single Supply Variable Gain Amplifier

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix 'T1' corresponds to tape and reel packaging as defined in the manufacturer's technical brief TB347. Confirm that the 'UU8IZ' designation aligns with the standard 8-lead MSOP package specifications. Ensure compatibility with the required 3V supply voltage limits before procurement.

Digital Potentiometers Selection Notes

Select this component when a low-power, solid-state variable resistor is required with persistent setting retention. The 50kΩ resistance value and 32-tap resolution are suitable for precision trimming applications. Verify that the system can accommodate the 3-wire serial interface timing requirements for increment and store operations.

Digital Potentiometers Part Context

This part belongs to the X9315 family of low noise, low power digitally controlled potentiometers. It is functionally similar to the X9315 but optimized for a 3V supply voltage. The device integrates a resistor array, wiper switches, control section, and nonvolatile memory into a compact surface-mount package.

Digital Potentiometers Replacement Considerations

The datasheet explicitly states 'NOT RECOMMENDED FOR NEW DESIGNS' and 'NO RECOMMENDED REPLACEMENT'. Engineers should consult the Technical Support Center for potential alternatives or consider redesigning with newer components.
