PSOC™ 4000T Multi-Sense Microcontrollers

Infineon PSOC 4000T MCUs offer superior capacitive sensing with ultra-low power, excellent signal-to-noise ratio, reliability, robustness, liquid tolerance, and multi-sense capabilities, including capacitive sensing, inductive sensing, liquid level sensing, and hover touch capabilities. The PSOC 4000T has an Arm® Cortex®-M0+ CPU and features the Infineon 5th generation high-performance CAPSENSE™ capacitive sensing subsystem.

The PSOC 4000T series enables a variety of applications, including wearables, hearables, and smart connected IoT products that need low-power operation and improved performance for an optimal user experience. It also offers an upgrade path for PSOC 4000- and PSOC 4000S-based designs to 5th generation CAPSENSE technology with software and package compatibility.

CAPSENSE Technology

Fifth generation CAPSENSE touch-sensing technology enables advanced power- and space-saving designs, making it an ideal solution for wearables and other battery-powered smart devices mode operation. With always-on sensing technology, it offers much lower power consumption in both active and standby modes, enabling a game-changing capability that helps to extend battery life.

Fifth generation CAPSENSE technology improves signal-to-noise (SNR) ratio performance by ten times that of previous generations with a unique ratio-metric sensing methodology, enabling smaller sensors for smaller factor designs and adding support for glove touch, improved proximity detection and gesture control, intuitive sensing such as liquid level detection, touch sensing over metallic surfaces, superior noise immunity, and a smooth design experience in challenging environmental conditions. CAPSENSE maintains touch accuracy in wet conditions, allowing for fully waterproof touch buttons.
