Infineon PSOC™ 4100T Plus MCUs
5th Gen CAPSENSE™ and Multi-Sense technology for advanced sensing solutions for system control and HMI applications
The PSOC™ 4100T Plus family of Arm® Cortex®-M0+ microcontrollers combines analog and digital blocks with Infineon’s high-performance Multi-Sense technology, which includes 5th generation CAPSENSE™, inductive sensing and liquid level sensing. The PSOC™ 4100T Plus represents a significant upgrade to the PSOC™ 4 family, offering advanced HMI capabilities through Multi-Sense, enhanced ESD protection, and improved clock accuracy.
Infineon's 5th Generation CAPSENSE™ technology offers significant improvements over its predecessors, featuring a 10 times higher signal-to-noise ratio (SNR) performance while consuming 10x less power. Building on this foundation, the PSOC™ 4100T Plus microcontrollers incorporate advanced inductive sensing capabilities, leveraging a differential and ratio-metric sensing architecture that provides flexibility in terms of sensor inductance and operating frequency. Furthermore, the PSOC™ 4100T Plus microcontrollers also feature a liquid level sensing technology that operates without requiring direct contact with the liquid, making it suitable for use in noisy environments. This technology is also capable of detecting different types of liquids while rejecting foam and residue, thereby enhancing its overall reliability and accuracy.
High memory options, combined with SAR ADC, MCU peripherals, and Multi-Sense makes PSOC™ 4100T Plus an ideal MCU for system control plus HMI applications.
