Cypress Semi Teams with Arm for Secure IoT MCU Solution

Cypress Semiconductor has expanded its collaboration with Arm to provide management of IoT edge nodes. The solution integrates the Arm Pelion IoT Platform with Cypress’ low power, dual-core PSoC 6 microcontrollers (MCUs) and CYW4343W Wi-Fi and Bluetooth combo radios. PSoC 6 provides Arm v7-M hardware-based security that adheres to the highest level of device protection defined by the Arm Platform Security Architecture (PSA).
Cypress and Arm demonstrated hardware-secured onboarding and communication through the integration of the dual-core PSoC 6 MCU and Pelion IoT Platform in the Arm booth at Arm TechCon last month. In the demo, the PSoC 6 was running Arm’s PSA-defined Secure Partition Manager to be supported in Arm Mbed OS version 5.11 open-source embedded operating system, which will be available this December. Embedded systems developers can leverage the private key storage and hardware-accelerated cryptography in the PSoC 6 MCU for cryptographically-secured lifecycle management functions, such as over-the-air firmware updates, mutual authentication and device attestation and revocation. According to the company, Cypress is making a strategic push to integrate security into its compute, connect and store portfolio for the IoT.

The PSoC 6 architecture is built on ultra-low-power 40-nm process technology, and the MCUs feature low-power design techniques to extend battery life up to a full week for wearables. The dual-core Arm Cortex-M4 and Cortex-M0+ architecture lets designers optimize for power and performance simultaneously. Using its dual cores combined with configurable memory and peripheral protection units, the PSoC 6 MCU delivers the highest level of protection defined by the Platform Security Architecture (PSA) from Arm.

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 features the latest generation of Cypress’ industry-leading CapSense capacitive-sensing technology, enabling modern touch and gesture-based interfaces that are robust and reliable.
