Infineon Technologies PSoC™ 4000T Arm® Cortex®-M0+ Microcontrollers

Infineon Technologies PSoC™ 4000T Arm® Cortex®-M0+ Microcontrollers features 5th generation CAPSENSE™ technology. The Infineon PSoC 4000T offers a 10x better signal-to-noise ratio (SNR) and 10x lower power consumption than the previous generation. This SNR and low power consumption allows always-on touch sensing for Human-Machine Interface (HMI), extending battery life in battery-powered products. The PSoC 4000T series provides reliability, robustness, liquid tolerance, and multi-sense capabilities. The device is suitable for wearable, hearable, and IoT devices that require low power and enhanced performance for a better user experience. Additionally, it offers 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 Sensing Technology

The 5th generation CAPSENSE touch-sensing tech is perfect for wearables and battery-powered smart devices. There is an “Always-On” feature that significantly reduces power usage in active and standby modes, extending battery life.
