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.
