"As a direct result of the security features built into PSoC 6 MCUs and
our collaboration with Arm, we have been able to quickly offer support
for Trusted Firmware-M," said
Cypress' PSoC 6 MCUs achieve the highest level of protection defined by the PSA using dual Arm Cortex®-M cores combined with configurable memory and peripheral protection units. The MCUs provide three levels of hardware-based isolation: 1) an isolated execution environment for trusted applications using a dedicated Arm Cortex®-M0+ core, 2) secure element functionality that hosts root of trust operations and system services, and 3) isolation for each trusted application. These three levels of isolation together reduce the attack surface for threats. The system is augmented with a true random number generator (TRNG) and cryptographic accelerators, while the Cortex-M4 core in the PSoC 6 MCU architecture delivers a clean programming model for the rich execution environment for unsecure applications.
Aligned with Arm's current version for v8-M, the Trusted Firmware-M reference example for PSoC 6 MCUs allows designers to:
- Easily implement hardware-based isolation between secure and unsecure execution environments via configuration of the protection units
- Utilize Mbed OS secure services.
Future versions will include trusted boot with multiple images and full PSA API support, including Root of Trust installation with secure element functionality.

About PSoC 6 MCUs
PSoC 6 is the industry's lowest power, most flexible MCU with built-in Bluetooth Low Energy wireless connectivity and integrated hardware-based security in a single device. Software-defined peripherals can be used to create custom analog front-ends (AFEs) or digital interfaces for innovative system components such as electronic-ink displays. The architecture offers flexible wireless connectivity options, including fully integrated Bluetooth Low Energy (BLE) 5.0. The PSoC 6 MCU architecture features the latest generation of Cypress' industry-leading CapSense® capacitive-sensing technology, enabling modern touch and gesture-based interfaces that are robust and reliable. The architecture is supported by Cypress' PSoC Creator™ Integrated Design Environment (IDE) and the expansive Arm ecosystem.
