X9315WMT1

Digital Potentiometers Overview

The X9315WMT1 is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features a single potentiometer with 32 taps and a resistance value of 10 kOhms. The device utilizes non-volatile memory to retain the wiper position during power-off conditions. Control is managed via a serial 3-wire interface, allowing for precise adjustment of the wiper position through CS, U/D, and INC inputs. The component operates within a supply voltage range of 4.5 V to 5.5 V and consumes a typical operating current of 50 uA. It is housed in an MSOP-8 surface-mount package.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power loss

• Linear taper with 32 resistive tap points
• Low power consumption of 50 uA typical operating current

Digital Potentiometers Applications

• Audio volume control circuits
• Variable gain amplifier settings
• Calibration adjustments in test equipment
• Voltage reference trimming

Digital Potentiometers Procurement Notes

Verify the specific suffix 'WMT1' against official Renesas documentation to confirm the exact package type and tape-and-reel specifications. Check for end-of-life status or limited availability as this series may have discontinued variants. Ensure RoHS compliance details are confirmed for the specific manufacturing batch before procurement.

Digital Potentiometers Selection Notes

Select this component when a low-power, non-volatile digital potentiometer with 10 kOhm resistance is required. Ensure the application supports the 4.5 V to 5.5 V supply voltage range. Verify that the MSOP-8 package dimensions fit the PCB layout constraints. Confirm that the 3-wire serial interface timing requirements match the microcontroller capabilities.

Digital Potentiometers Part Context

The X9315WMT1 belongs to the X9315 family of digitally controlled potentiometers from Renesas. This family is designed for applications requiring adjustable resistance without mechanical wear. The 'W' typically denotes the MSOP package, while 'M' and 'T1' relate to moisture sensitivity and reel packaging specifications respectively.

Digital Potentiometers Replacement Considerations

Direct substitutes include other X9315 variants such as X9315WMIZT1 or X9315WSZT1, provided the resistance value and package compatibility are verified. Cross-reference pinouts and electrical characteristics carefully before substitution.
