DEV KIT WEEKLY: Infineon PSoC 4000T CAPSENSE Prototyping Kit

June 11, 2024


This prototyping kit is designed to allow developers to work with the PSoC 4, a family of scalable MCUs with an Arm Cortex-M0+ CPU. The new PSoC 4000T series provides an upgrade path for the 4000 and 4000S designs to move them to fifth-generation HMI and CAPSENSE technology, with an ultra-low power touch HMI solution based on an integrated “Always-On” sensing technology.

Infineon has improved performance in the 4000T to enable modern UI solutions, better liquid tolerance, and more robustness and reliability in harsh environments. It’s a micro controller with standard communication options and timing peripherals. Infineon says its fifth generation CAPSENSE and multi-sense HMI technology are purpose built for low power applications like wearables, hearables and other smart, connected IoT products that need great performance and power efficiency to enable next generation of user experience.

This kit has the 32-bit MCU subsystem, with a 48-MHz Arm Cortex-M0+ CPU with single-cycle multiply, up to 64K of flash with read accelerator, and up to 8K of SRAM. It’s designed to be low-power, with 1.71 to 5.5 V operation and a deep sleep mode with 6 µA, always-on touch sensing and active touch detection and tracking at an average of 200µA. 

The fifth generation CAPSENSE features an all-new ratio-metric sensing architecture in multi-sense converter low power has an excellent signal-to-noise ratio at less than 5:1, and great liquid tolerance for capacitive sensing.

There’s no shortage of ML and AI options either, with autonomous channel scanning, advanced proximity sensing with directivity, and automatic hardware tuning via Infineon’s SmartSense.

For serial communication, this prototyping kit includes two independent runtime reconfigurable serial communication blocks with re-configurable I2C, SPI, or UART functionality in one block with master/slave I2C functionality in the other. It has both timing and pulse-width modulation and two 16-bit timer/counter/pulse-width modulator blocks, comparator-based triggering of kill signals, quadrature decoder, plus or minus 2 percent internal main oscillator, 40 kHz Internal low-power oscillator, up to 21 programmable GPIO pins that can have sensing or digital functionality, and lots more.

The PSoC 4000T CAPSENSE Prototyping Kit from Infineon is an amazing choice for any engineer or developer looking to work on a prototype for any new wearable like smart watches, smart glasses, AR/VR glasses, or smart earbuds. It’s also set for low-power battery-powered smart home devices like thermostats, robotic vacuums, smart locks, remote controls, and smart speakers, or even appliances and peripherals like range hoods, coffee makers, microwaves, ovens, printers, and access controls.

We encourage you to check out one of these prototyping boards at and explore all the possibilities. Each one should cost just over $20, so it’s super easy to get going.
