X9C503SZT1

Overview

The X9C503SZT1 is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features a single-channel, linear taper resistance network with a nominal value of 50 kOhms and 100 tap points. The device utilizes non-volatile memory to retain wiper position settings across power cycles. Control is managed via a three-wire serial interface using CS, U/D, and INC inputs. It operates on a single 5V supply within a voltage range of 4.5V to 5.5V and consumes approximately 1 mA of current. The component is housed in an 8-lead SOIC surface-mount package and is rated for operation between 0°C and +70°C.

Feature Summary

• Non-volatile memory storage retains wiper position upon power-up
• Three-wire serial interface (CS, U/D, INC) for control
• Linear taper resistance with 100 discrete tap positions
• Single-channel configuration in 8-SOIC package

Applications

• Signal processing parameter adjustment
• Control system variable resistance
• Hardware gain or offset calibration

Procurement Notes

Verify the specific suffix 'T1' against the manufacturer's official datasheet to confirm reel packaging specifications and any distinct electrical tolerances compared to standard tube-packaged variants like X9C503SZ. Ensure compatibility with 5V logic levels and check for RoHS3 compliance status in current production notices.

Selection Notes

Select this component when a non-volatile digital potentiometer with 50k Ohm resistance is required. The 100-tap resolution provides moderate granularity suitable for general-purpose adjustments. Verify that the 0°C to +70°C commercial temperature range meets the environmental requirements of the target application.

Part Context

This part belongs to the X9C503 series of Digitally Controlled Potentiometers (XDCP). The series includes variants such as X9C102, X9C103, and X9C104, which share similar architectural features but differ in resistance values. The X9C503 specifically offers a 50k Ohm resistance option within this family.

Replacement Considerations

Direct pin-compatible substitutes within the same family include X9C503SZ (tube package) and X9C503SIZT1 (industrial temperature grade -40°C to +85°C). Verify if the extended temperature range of the 'I' variant is necessary for the specific deployment environment.
