X9313ZSI-3T1

Digital Potentiometers Overview

The X9313ZSI-3T1 is a single-channel solid-state digital potentiometer manufactured by Renesas Electronics Corporation. It features an end-to-end resistance of 1 kOhm with 32 taps and linear taper characteristics. The device operates within a supply voltage range of 3 V to 5.5 V, drawing a maximum operating current of 1 mA. It utilizes a nonvolatile memory architecture to retain wiper position data upon power cycling. The component communicates via a 3-wire serial interface and is housed in an 8-pin SOIC surface-mount package, suitable for industrial temperature ranges from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Nonvolatile storage retains wiper position after power loss
• 3-wire up/down serial control interface (CS, U/D, INC)
• Linear resistance taper with 32 adjustable taps
• Operates on 3 V to 5.5 V supply voltage

Digital Potentiometers Applications

• Digitally controlled resistance trimming
• Parameter adjustment in instrumentation
• Signal processing circuit configuration

Digital Potentiometers Procurement Notes

Verify the specific suffix '3T1' against official Renesas documentation to confirm tape-and-reel packaging specifications and moisture sensitivity levels. Ensure compatibility with standard SOIC-8 footprint requirements during PCB layout. Cross-reference RoHS compliance status with the latest manufacturer declarations prior to procurement.

Digital Potentiometers Selection Notes

Select this model for applications requiring precise 1 kOhm resistance adjustment with persistent settings. Confirm that the 3-wire interface aligns with the host microcontroller's available GPIO pins. Verify that the ±20% tolerance and ±300ppm/°C temperature coefficient meet the system's accuracy requirements.

Digital Potentiometers Part Context

This component belongs to the XDCP™ family of digitally controlled potentiometers. It serves as a solid-state replacement for mechanical potentiometers, offering improved reliability and programmability. The ZSI variant specifically denotes the 1 kOhm resistance value packaged in an SOIC-8 form factor.

Digital Potentiometers Replacement Considerations

X9313ZSIZT1: Pin-compatible alternative with identical electrical specifications but potentially different packaging or manufacturing lot details. Verify pinout consistency before substitution.
