ISL95810UART8Z-T

Digital Potentiometers Overview

The ISL95810UART8Z-T is a single-channel non-volatile digital potentiometer from the XDCP series by Renesas Electronics. It features a resistance value of 50 kΩ with 256 taps and utilizes an I²C serial interface for control. The device operates on a supply voltage range of 2.7 V to 5.5 V, drawing approximately 1 mA of operating current. It is housed in an 8-lead XDCP package and supports an industrial temperature range from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position upon power loss
• I²C serial interface for digital control
• Single channel with 256 linear taps
• 50 kΩ resistance value with ±20% tolerance

Digital Potentiometers Applications

• Calibration of sensor offsets
• Adjustable gain settings in signal conditioning circuits
• Voltage reference trimming

Digital Potentiometers Procurement Notes

Verify the exact suffix 'UART8Z-T' against official Renesas documentation, as standard listings typically use 'UIRT8Z-T' or similar variants for the 50kΩ MSOP version. Confirm RoHS compliance status and check for End-of-Life (EOL) notices, as previous ISL95810 variants have faced obsolescence. Ensure the package type matches the design footprint requirements.

Digital Potentiometers Selection Notes

Select this component when non-volatile storage is required to maintain resistance settings without continuous power. The 50 kΩ value suits moderate impedance applications. Verify that the I²C address configuration meets system bus constraints. Consider the ±20% resistance tolerance and ±45ppm/°C temperature coefficient for precision requirements.

Digital Potentiometers Part Context

The ISL95810 belongs to Renesas' XDCP (eXtreme Digital Control Potentiometer) family, designed to replace mechanical potentiometers in space-constrained PCB designs. It integrates EEPROM for data retention. Other variants in the series include different resistance values such as 10 kΩ (ISL95810WIRT8Z).

Digital Potentiometers Replacement Considerations

Direct pin-to-pin replacements may include other ISL95810 variants with different suffixes indicating package or temperature grade changes. Cross-reference with Microchip MCP41xxx or Analog Devices AD52xx series only if interface and voltage levels are compatible.
