X9317TP-2.7

Digital Potentiometers Overview

The X9317TP-2.7 is a digitally controlled potentiometer (XDCP) from the Renesas X9317 series, manufactured by Renesas Electronics Corporation. It features a single resistive element with a nominal resistance of 50 kOhms and 100 tap positions for precise adjustment. The device utilizes non-volatile memory to retain the wiper setting upon power loss. It operates within a supply voltage range of 2.7V to 5.5V and employs an Up/Down (U/D), Increment (INC), and Chip Select (CS) serial interface for control. The component is housed in an 8-TSSOP surface-mount package.

Digital Potentiometers Feature Summary

• Single-channel digital potentiometer with 50 kOhm total resistance and 100 taps.
• Non-volatile memory retains the last wiper position after power cycle.
• Operates on a wide supply voltage range of 2.7V to 5.5V.
• Controlled via a simple 3-wire Up/Down, Increment, and Chip Select interface.

Digital Potentiometers Part Context

The X9317TP-2.7 belongs to the X9317 family of CMOS XDCPs. This series is characterized by its low power consumption and ability to replace mechanical potentiometers in various electronic circuits. The 'TP' suffix typically indicates a specific tape-and-reel packaging configuration, while '-2.7' denotes the lower end of the operating voltage range.

Digital Potentiometers Replacement Considerations

Direct replacement part numbers include X9317UV8IZ-2.7T1. When substituting, verify that the pinout and package dimensions (8-TSSOP) are compatible with the existing PCB footprint. Ensure the replacement component supports the required 2.7V minimum supply voltage and non-volatile functionality.
