R7F100TEE3G00CNP#BA0

Touch Capacitive Sensor Overview

The R7F100TEE3G00CNP#BA0 is a capacitive touch sensor IC from Renesas Electronics, belonging to the CT1 series. It features 19 sensing channels and operates within an extended industrial temperature range of -40°C to +105°C. The component is housed in a compact 40-pin HWQFN package designed for surface-mount technology. This integrated circuit is engineered specifically for touch interface applications, providing dedicated hardware support for reliable capacitive detection without requiring complex processing from a host microcontroller.

Touch Capacitive Sensor Feature Summary

• Dedicated capacitive touch sensing architecture with 19 independent input channels
• Extended operational temperature range suitable for demanding industrial environments
• Compact surface-mount packaging optimized for space-constrained designs

Touch Capacitive Sensor Applications

• Industrial control panels requiring robust touch interfaces
• Automotive interior components operating in high-temperature zones
• Consumer appliances with sealed or wet-environment touch controls

Touch Capacitive Sensor Procurement Notes

Verify the exact suffix against official Renesas documentation, as the provided reference indicates #BA0 while source data lists #AA0. Confirm availability through authorized distributors, as stock status may vary by region. Ensure compliance with RoHS directives and check for any recent product change notices affecting lead times or manufacturing locations before finalizing procurement plans.

Touch Capacitive Sensor Selection Notes

Select this component when a standalone touch controller is required rather than software-based solutions on a general MCU. The 19-channel capacity supports larger keypads or slider interfaces. Consider the HWQFN-40 footprint during PCB layout to ensure adequate thermal dissipation and mechanical stability within the specified -40°C to +105°C operating window.

Touch Capacitive Sensor Part Context

This part belongs to the Renesas CT1 family of capacitive touch controllers, distinct from the RL78 microcontroller series found in other R7F100 variants. While sharing the R7F100 prefix, it functions as a peripheral touch IC rather than a programmable processor. It complements main system MCUs by handling touch sensing duties independently.

Touch Capacitive Sensor Replacement Considerations

R7F100TEE3G00CNP#AA0 is listed as a variant in public records. Verify if the suffix change denotes only packaging or environmental rating differences. No direct cross-manufacturer substitutes are documented; design-in alternatives require separate evaluation.
