German electronics company Infineon has announced a family of microcontrollers for sensing applications in wearables, hearables and smart connected IoT devices.
The PSoC 4000T MCUs are said to deliver best-in-class low-power capacitive sensing with signal-to-noise ratio (SNR), liquid tolerance and multi-sense capabilities coupled with reliability and robustness.
They expand the PSoC 4 family of Arm Cortex-M0+ based MCUs, featuring Infineon’s fifth-generation Capsense capacitive sensing technology. The current generation provides ten times higher SNR performance and ten times lower power consumption than previous generations.
The PSoC 4000T has always-on touch sensing capability that enables human machine interface (HMI) operation with low-active and standby power consumption to support longer battery life for battery-powered products. Designers can now use a range of sensing support from the PSoC 4000T, including proximity, humidity, temperature and ambient light sensing.
The fifth-generation Capsense technology enables interactive user interfaces for applications using proximity gestures, capacitive sliders, capacitive trackpads, small size touchscreens, wear detection and liquid level sensing.
“At Infineon, we are committed to providing innovative and cutting-edge technologies that meet the evolving needs of our customers,” said Steven Tateosian, senior vice president of Infineon’s IoT, compute and wireless business unit. “The PSoC 4000T including our fifth-generation Capsense technology represents a significant leap forward in the evolution of human-machine interfaces and sets a new standard in the industry.”
The PSoC 4000T family provides an upgrade path for PSoC 4000- and PSoC 4000S-based designs to utse the fifth-generation Capsense via software and package compatibility. The series targets low-power applications including wearables, hearables and smart connected IoT devices.
ModusToolbox software from Infineon (www.infineon.com) provides a collection of development tools, libraries and embedded runtime assets for a flexible and comprehensive development experience. It integrates the PSoC 4000T family in the latest release. ModusToolbox supports a wide range of use cases including consumer IoT, industrial, smart home and wearable applications.
The PSoC 4000T is available with 15 variants. To match users’ needs, the MCU can be ordered in SG-XFWLB-25, PG-USON16 and PG-VQFN-24 packages, with either 24 or 4MHz, 32 or 64 kbyte flash, and 4 or 8kbyte SRAM.
