Flexible MCU improves touch-sensing performance in HMI applications

New Infineon PSoC 4100S Max supports latest CAPSENSE technology, and provides more memory capacity and I/Os.

Infineon has introduced the PSoC™ 4100S Max family of microcontrollers which support the fifth-generation CAPSENSE™ touch-sensing technology, bringing new capabilities and better performance to human-machine interface (HMI) applications in smart home, industrial and automotive applications.

The Infineon PSoC 4100S Max’s new features include dual fifth-generation CAPSENSE blocks, which offer a better signal-to-noise ratio thanks to a new ratiometric analog architecture and advanced hardware filtering. This results in superior liquid tolerance, and robust and reliable touch-sensing performance in harsh environments. The fifth-generation CAPSENSE also gives higher sensitivity to enable the use of smaller sensors, as well as longer proximity detection range. The new CAPSENSE supports a much wider range of overlay thicknesses and materials.

The PSoC 4100S Max, which includes a 48 MHz Arm® Cortex®-M0+ CPU core with a DMA controller, features up to 384 kbytes of Flash memory and up to 84 GPIOs, as well as a CAN-FD controller. An I2S master interface supports fully embedded audio solutions. This latest PSoC device also includes a cryptographic accelerator for fast and efficient cryptographic operations. 

The MCU is supplied in various TQFP package sizes: 48-lead 7 mm x 7 mm, 64-lead 10 mm x 10 mm, and 100-lead 14 mm x 14 mm. 

The MCU is compatible with the latest ModusToolbox™ 3.0 development platform, which can be downloaded from the Infineon Developer Center. The ModusToolbox software, which provides a collection of development tools, libraries, and embedded runtime assets, offers a flexible and comprehensive development experience.
