PSoC™ 64 Secure Microcontrollers

PSoC 64 Security Line

The PSoC 6 architecture is built on an ultra-low-power 40-nm process technology, and the MCUs leverage low-power design techniques to extend battery life up to a full week for secured wearables. A choice of dual-core Arm Cortex-M4 or Cortex-M0+ architecture lets designers optimize for power and performance simultaneously. Designers can use the MCU’s software-defined peripherals to create custom analog front-ends (AFEs) or digital interfaces for innovative system components such as electronic-ink displays. The PSoC 6 MCU also features the latest generation of Infineon’s industry-leading CAPSENSE capacitive-sensing technology, enabling modern touch and gesture-based interfaces that are robust and reliable.

psa certified

Infineon’s PSoC 64 secured MCUs were one of the first Arm® Cortex®-M processors to be certified as PSA Level 1-compliant. With the new PSA Level 2 certification, developers of IoT systems have an extended level of trust when they use PSoC 64 secured MCUs, which are equipped with the Arm® PSA holistic set of threat models, security analyses, hardware and firmware architecture specifications. The PSoC 64 MCUs are ideal for cloud-connected applications that require protection of user data and trustworthy firmware updates.
