CY8CMBR3155-LQXIT

Overview

The CY8CMBR3155-LQXIT is a capacitive touch controller from Infineon Technologies, part of the CapSense Express family. It features a QFN-16 package and supports I2C and GPO interfaces. The device operates within a supply voltage range of 1.71 V to 5.5 V and functions at temperatures between -40°C and +85°C. It is designed for applications requiring reliable touch sensing with low power consumption.

Feature Summary

Capacitive touch sensing capability
I2C and GPO interface support
Wide operating voltage range
Extended temperature operation

Applications

Consumer electronics touch interfaces
Industrial control panels
Home appliance user interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure storage conditions meet JESD-020 standards to prevent damage. Cross-reference datasheet revisions for any updates to electrical characteristics or pin assignments before finalizing design integration.

Selection Notes

Select this component for designs requiring robust capacitive touch input with minimal external components. Consider the QFN-16 footprint for space-constrained layouts. Evaluate system voltage compatibility with the 1.71V to 5.5V range. Assess thermal requirements against the -40°C to +85°C operational window for environmental suitability.

Part Context

This part belongs to Infineon's CapSense Express series, optimized for simple, cost-effective touch solutions. It integrates sensing algorithms internally, reducing microcontroller load. The LQXIT suffix indicates specific packaging and tape/reel configuration suitable for automated surface-mount assembly processes in high-volume manufacturing environments.

Replacement Considerations

Check for direct substitutes within the same CapSense Express family with compatible pinouts and functionality. Verify if alternative packages like SOIC are available if layout changes are permissible. Ensure any replacement maintains I2C/GPO interface compatibility and similar voltage/temperature specifications.
