MCU Family Achieves PSA Level 2 Certification For Secure IoT Devices

390

Infineon Technologies recently announced the company has achieved the Arm Platform Security Architecture (PSA) Level 2 certification for the PSoC 64 microcontrollers (MCUs) standard secure family of devices.

The Level 2 certification includes a laboratory evaluation of the PSA Root of Trust (PSA-RoT) to provide evidence that devices can protect against scalable software attacks. The evaluation labs use vulnerability analysis and penetration testing of the PSA-RoT to establish if the nine security requirements of the PSA-RoT Protection Profile have been met.

The company said its 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 said to be ideal for cloud-connected applications that require protection of user data and trustworthy firmware updates, including personal healthcare devices and home security solutions.

“This next-level of certification further assures our IoT solution developers that their smart, connected devices are built on a secured foundation, in line with PSA. Additionally, this certification builds on our secured platform, making customers’ lives simpler, and more secured,” Erik Wood, director of IoT Secure MCU Products, Infineon Technologies.

About Infineon PSoC 6 MCUs

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 optimise 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.

The PSoC 64 devices are available now from Infineon Technologies.
