QT60248-AS

Overview

The QT60248-AS is a capacitive touch sensor integrated circuit from Microchip Technology, designed for QMatrix applications. It supports up to 24 buttons and features an SPI interface for communication. The device includes Adjacent Key Suppression (AKS) functionality to enhance sensing accuracy. It operates within a voltage range of 3V to 5V and is housed in a 32-TQFP package measuring 7x7 mm.

Feature Summary

Supports QMatrix sensing architecture for robust touch detection
Integrates Adjacent Key Suppression (AKS) technology
Utilizes SPI interface for system connectivity

Applications

Consumer electronics touch interfaces
Industrial control panels
Appliance user interfaces

Procurement Notes

Verify the specific suffix 'AS' against the official Microchip datasheet to confirm pinout and electrical characteristics. Note that availability status may vary; check current lifecycle notifications as some variants are marked obsolete. Ensure the 32-TQFP package dimensions match your PCB footprint requirements before ordering.

Selection Notes

Select this component when a cost-effective solution for up to 24 touch keys is required. It is suitable for designs needing SPI communication and AKS features. Consider the 3V-5V operating range for power supply compatibility. Evaluate the 32-TQFP package size against board space constraints during the initial design phase.

Part Context

This part belongs to the QT60240/QT60248 family of QMatrix Touch Sensor ICs. These devices are engineered for embedded systems requiring reliable capacitive touch input. The family shares common architectural features but differs in key count and package options. This specific model targets mid-range applications with moderate I/O requirements.

Replacement Considerations

Check for direct substitutes within the same product family, such as the QT60240 series, if fewer keys are sufficient. Verify package compatibility and software driver support for any alternative components. Consult Microchip's discontinuation notices for legacy parts to identify recommended new designs.
