X9315UMIZ

Digital Potentiometers Overview

The X9315UMIZ is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features a single potentiometer with 32 taps and a resistance value of 50 kOhms. The device utilizes nonvolatile memory to retain wiper position settings during power-off events. Control is managed via a 3-wire serial interface consisting of CS, U/D, and INC inputs. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an industrial temperature range from -40°C to +85°C. The component is housed in an 8-lead MSOP package.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position upon power-up
• 3-wire serial control interface (CS, U/D, INC)
• Single potentiometer with 32 linear taps
• Operating supply voltage range: 2.7 V to 5.5 V

Digital Potentiometers Applications

• Battery-powered systems requiring low power consumption
• Industrial process control for gain adjustment
• Audio volume control applications
• Programmable filter frequency setting

Digital Potentiometers Procurement Notes

Verify the specific suffix 'MIZ' against official Renesas documentation to confirm package type and temperature grade. Confirm current production status as some variants in this series may be subject to limited availability or end-of-life notices. Ensure compatibility with existing PCB footprint for the MSOP-8 package.

Digital Potentiometers Selection Notes

Select the X9315UMIZ when a 50 kOhm resistance value is required. Compare with the X9315TMIZ variant if a 100 kOhm resistance is needed instead. Verify that the 3-wire interface matches the microcontroller's available GPIO pins. Check if the industrial temperature range (-40°C to +85°C) meets the application environment requirements compared to commercial grade options.

Digital Potentiometers Part Context

The X9315UMIZ belongs to the X9315 family of low noise, low power digitally controlled potentiometers. This family is characterized by its use of CMOS technology and EEPROM-based nonvolatile memory. The device serves as a solid-state replacement for mechanical potentiometers in circuits where manual adjustment is not feasible or where digital control of resistance is necessary.

Digital Potentiometers Replacement Considerations

Direct pin-to-pin replacements within the same package include other X9315 variants such as X9315USIZ (SOIC-8) or X9315TMIZ (100k Ohm). Verify resistance tolerance and taper characteristics match the original design requirements before substitution.
