SX8650IWLTRT

Overview

The SX8650IWLTRT is a low-power resistive touch screen controller from Semtech, designed for portable electronic devices. It features a 12-bit analog-to-digital converter (ADC) for high-precision coordinate and pressure measurement. The device supports I2C interface communication with a maximum speed of 400 kHz in fast mode. Operating voltage ranges from 1.65V to 3.7V, with typical power consumption optimized for battery-operated applications. It includes robust electrostatic discharge (ESD) protection rated at ±15kV.

Feature Summary

• Extremely low power consumption of 23uA
• Compact package size of 1.46mm x 1.96mm
• Enhanced ESD protection up to ±15kV
• 12-bit ADC for precise touch detection

Applications

• Mobile phones
• Digital cameras
• MP3 players
• Personal navigation devices
• Handheld game consoles

Procurement Notes

Verify the specific suffix 'IWLTRT' against official Semtech documentation to confirm tape-and-reel packaging and temperature grade. Confirm end-of-life status or availability through authorized distributors prior to procurement planning.

Selection Notes

Select this component for space-constrained designs requiring low current draw. Ensure the host system supports I2C communication at 400 kHz. Verify that the application environment does not exceed the ±15kV ESD rating without additional external protection.

Part Context

The SX8650 is the first product in Semtech's new platform of resistive touch controllers. It serves as a foundational model for subsequent variants like the SX8652, which offers similar functionality but may differ in interface type or package options.

Replacement Considerations

Check for direct pin-compatible replacements within the SX865x family. Verify if alternative models offer improved performance metrics or updated packaging suitable for current manufacturing requirements.
