Infineon Technologies PSOC™ 4000T Multi-Sense MCUs
Infineon Technologies PSOC™ 4000T Multi-Sense Microcontrollers (MCUs) feature Infineon’s fifth-generation CAPSENSE™ technology with Multi-Sense capabilities, including capacitive sensing, inductive sensing, liquid level sensing, and hover touch capabilities. The supported sensing technologies are combined in a single PSOC 4 MCU to optimize performance, enable new use cases, or realize cost savings.
The PSOC 4000T series provides reliability, robustness, liquid tolerance, and Multi-Sense capabilities. The devices are suitable for wearables, hearables, and Internet of Things (IoT) devices that require low power and enhanced performance for a better user experience. Additionally, these MCUs offer an easy upgrade path for existing PSOC 4000 and PSOC 4000S designs to the fifth-generation CAPSENSE technology with software and package compatibility.
CAPSENSE™ Touch and Multi-Sense Technology
Infineon’s 5th Generation CAPSENSE technology expands its leading capacitive sensing technology with a proprietary inductive sensing technology, as well as a non-invasive and non-contact liquid sensing solution. 5th Generation CAPSENSE provides 10x higher SNR (signal-to-noise ratio) performance with 10x lower consumption than previous generations of CAPSENSE. The 5th generation CAPSENSE touch-sensing tech is ideal for wearables and battery-powered smart devices. An always-on feature significantly reduces power usage in active and standby modes, extending battery life.
