MCU product delivers efficient capacitive inductive technology

Rutronik has expanded its MCU portfolio with the PSOC 4000T from Infineon Technology. This adds advanced HMI functions to Infineon's 48MHz Arm Cortex-M0+ based MCU product family. The MCUs combine capacitive, inductive, and liquid-based sensing in a single device. Developers benefit from greater design flexibility, improved energy efficiency, and new possibilities for touch and level sensing applications, even in harsh environments.

This expansion of the family brings multi-sense capabilities together in a single MCU, including the latest CAPSENSE generation, proprietary inductive sensing, and advanced liquid detection with AI-based signal processing. The new platform facilitates capacitive, inductive, and liquid-based sensing with a single device, making it excellent for modern, compact, and robust designs. The integration of features such as Hover Touch and Touch-over-Metal reduces hardware complexity, while the fifth generation of CAPSENSE with 'always-on' technology reduces power consumption by a factor of ten.

The associated PSOC 4000T Multi-Sense Prototyping Kit, the CY8CPROTO‑040T‑MS Kit, allows fast and modular evaluation of capacitive, inductive, and contactless sensor technology based on the fifth generation of CAPSENSE technology. Combining low-power architecture, versatile sensor support, and seamless integration into the ModusToolbox, the kit is excellent for developing energy-efficient HMI and IoT applications. Developers benefit from a flexible prototyping environment that greatly accelerates the validation of innovative user interfaces. The evaluation kit is divided into several daughter boards and a control board: The daughter boards consist of two touch-over-metal boards, an FPC for level measurement with a container, and a Hover Touch with multiple buttons.

Application examples include household and health appliances, building security systems, and industrial equipment.
