Infineon Introduces PSOC™ 4100T Plus MCU with Advanced Multi-Sense Capabilities for Smarter System Control and HMI

Infineon Technologies AG has launched the PSOC™ 4100T Plus, an Arm® Cortex®-M0+ microcontroller (MCU) equipped with cutting-edge Multi-Sense technology. This new MCU delivers a robust combination of analog and digital features, offering 128KB of Flash memory, 32KB of SRAM, and Infineon's high-performance Multi-Sense capabilities—including CAPSENSE™, inductive sensing, and liquid level detection.

Designed with enhanced reliability and a suite of advanced sensing features, the PSOC 4100T Plus provides a complete solution for system control and human-machine interface (HMI) applications.

“Infineon is committed to delivering best-in-class solutions for system control and HMI, with an emphasis on reliability,” said Vibheesh Bharathan, Director and Program Lead for PSOC 4 Multi-Sense at Infineon. “Our Multi-Sense technology represents a paradigm shift, enabling the next generation of sensing solutions for both consumer and industrial applications. We are building future-ready digital interfaces through powerful, integrated sensing capabilities.”

The PSOC 4100T Plus offers design flexibility: it can serve as a standalone general-purpose MCU for robust control and management, a dedicated HMI MCU for responsive and intuitive user interfaces, or a single-chip solution that unifies system control with advanced touch functionality.

In HMI-focused configurations, the MCU supports a variety of sensing technologies:

• Capacitive sensing for detecting touch and proximity

• Inductive sensing for touch detection on metal surfaces

• ML-based liquid level sensing for fluid presence and volume detection

• Hover touch sensing using CAPSENSE, enabling non-contact gesture interactions

These features make the PSOC 4100T Plus an ideal platform for developing innovative, user-friendly interfaces in next-generation devices.

Built for versatility, this powerful MCU platform supports a wide range of applications, including home appliances, consumer electronics, and touchpad/touchscreen solutions, offering manufacturers a scalable path toward smarter, more interactive product designs.
