Touch Capacitive Sensor Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pinout and feature configuration. Check availability status as distribution may vary by region. Ensure compliance with RoHS directives and moisture sensitivity levels relevant to your assembly process before finalizing procurement.

Touch Capacitive Sensor Selection Notes

Select this model when both 16-bit processing and capacitive touch functionality are required in a compact form factor. Compare pin counts and peripheral sets against alternative RL78/G23 or G24 variants if different I/O requirements exist. Confirm that the HWQFN-40 package dimensions fit the target PCB layout constraints.

Touch Capacitive Sensor Part Context

This component is part of the RL78/G24 family, which emphasizes high performance and low power consumption. It integrates a capacitive touch controller alongside the standard MCU peripherals, distinguishing it from basic RL78/G23 models. The series targets cost-sensitive applications requiring enhanced user interaction capabilities without external sensors.

Touch Capacitive Sensor Replacement Considerations

Consult the official Renesas replacement guide for obsolete parts. Verify compatibility with RL7F100TGE3G00CNP#AA0 or other G24 series members, ensuring pin-to-pin compatibility and identical peripheral configurations before substitution.
