PSoC™ 4 MCU: PSoC™ 4000T datasheet
Based on Arm® Cortex®-M0+ CPU
General description
PSoC™ 4 is a family of scalable MCUs with an Arm® Cortex®-M0+ CPU. It combines a high-performance capacitive
sensing subsystem, programmable and reconfigurable analog and digital blocks. The new PSoC™ 4000T series
provides an upgrade path for PSoC™ 4000 and PSoC™ 4000S based designs to fifth-generation HMI technology
with software and package compatibility.
PSoC™ 4000T is a member of the PSoC™ 4 MCU family with fifth-generation CAPSENSE™ and multi-sense
technology offering ultra-low power touch HMI solution based on an integrated “Always-On” sensing technology,
improved performance to enable modern sleek user interface solutions with superior liquid tolerance and
provides robust and reliable touch HMI solution for harsh environments.
PSoC™ 4000T is a microcontroller with standard communication, timing peripherals and Infineon’s fifth-
generation CAPSENSE™ and multi-sense HMI technology purpose built for varieties of low power applications
including wearable, hearable and smart connected IoT products that needs low power operation and improved
performance to enable next generation of user experience.
