X9313UMI-3T1

Digital Potentiometers Overview

The X9313UMI-3T1 is a single-channel digital potentiometer from the Renesas XDCP series, housed in an 8-MSOP surface-mount package. It features a total resistance of 50 kΩ with 32 tap points and linear taper characteristics. The device operates on a supply voltage ranging from 3 V to 5.5 V and utilizes a non-volatile memory architecture to retain wiper settings upon power loss. Control is achieved via a standard 3-wire serial interface (U/D, INC, CS). Key electrical parameters include a typical temperature coefficient of ±300 ppm/°C, a contact resistance of 40 Ω, and a maximum operating temperature of +70°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position after power cycle
• 3-wire serial interface for simplified control
• Linear taper with 32 discrete tap positions
• Single channel configuration in compact 8-MSOP package

Digital Potentiometers Applications

• Volume control in audio equipment
• Gain adjustment in instrumentation amplifiers
• Voltage reference trimming
• Programmable biasing circuits

Digital Potentiometers Procurement Notes

Verify the specific suffix 'I' indicates the industrial or extended temperature range variant compared to standard commercial versions. Confirm the '-3T1' suffix denotes tape-and-reel packaging with a standard reel quantity of 2,500 units. Ensure compatibility with the target PCB footprint for the 8-MSOP package before ordering.

Digital Potentiometers Selection Notes

Select this component when non-volatile storage of the resistance setting is required without external EEPROMs. The 50 kΩ value suits moderate impedance applications; lower resistance variants like the 1 kΩ model are available if higher current handling is needed. Verify that the 3-wire interface aligns with the host microcontroller's available GPIO pins.

Digital Potentiometers Part Context

This part belongs to the X9313 family of solid-state digital potentiometers. Variants within the family differ primarily by resistance value (e.g., 1 kΩ, 10 kΩ, 50 kΩ) and packaging suffixes indicating tube or reel formats. The X9313 series is designed as a drop-in replacement for mechanical potentiometers in space-constrained designs.

Digital Potentiometers Replacement Considerations

Direct substitutes include other X9313 variants with matching 50 kΩ resistance and non-volatile features, such as the X9313UMIZ or X9313UMZT1, provided the temperature range and packaging format meet the design requirements.
