X9C102SZT1

Overview

The X9C102SZT1 is a non-volatile digital potentiometer from the X9C10 series manufactured by Renesas Electronics. It features a single channel with a resistance value of 1 kΩ and 100 taps, utilizing a linear taper configuration. The device operates on a 5V supply voltage and employs a serial 3-wire interface (U/D, INC, CS) for control. Packaged in an 8-SOIC surface-mount format, it maintains its wiper position without power due to non-volatile memory. The component supports a typical temperature coefficient of ±600 ppm/°C and functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Non-volatile EEPROM storage retains wiper settings after power loss
• Serial 3-wire interface (Up/Down, Increment, Chip Select)
• 1 kΩ resistance with 100 linear taps
• Single-channel CMOS digital potentiometer

Applications

• Volume control in audio equipment
• Gain adjustment in signal conditioning circuits
• Voltage reference trimming
• System calibration requiring persistent settings

Procurement Notes

Verify RoHS compliance status as datasheets indicate variations between manufacturing lots or specific suffixes. Confirm package dimensions against the 8-SOIC specification (0.154 inch width). Ensure the ordering part number matches the required temperature grade and tape/reel packaging quantity of 2500 units if applicable.

Selection Notes

Select this model for applications requiring low resistance values (1 kΩ) and precise digital adjustment. Compare with X9C103SZT1 if a 10 kΩ resistance is needed instead. Verify that the 5V logic levels are compatible with the controlling microcontroller. Consider the ±20% tolerance and ±600 ppm/°C temperature coefficient for precision requirements.

Part Context

This component belongs to the X9C10 family of non-volatile digital potentiometers. It serves as a solid-state replacement for mechanical potentiometers in space-constrained designs. The 'SZ' suffix typically denotes the SOIC-8 package, while 'T1' indicates tape and reel packaging for automated assembly.

Replacement Considerations

The X9C102ST1 is listed as obsolete with the X9C102SZT1 identified as a direct replacement. Verify pinout compatibility when transitioning from older stock or alternative packages like PDIP.
