New ARM Technologies for Secure IoT Applications

ARM recently released a new product suite of technologies for designers of secure Internet of Things (IoT) applications.The product suite comprises procesors, cloud-based services platform, radio technology, subsystems, and comprehensive security.

Cortex-M Processors Integrated with TrustZone

The ARM Cortex-M23 and Cortex-M33 are built on the ARMv8-M architecture featuring ARM TrustZone security and digital signal processing. TrustZone CryptoCell-312 offers security features that protect the authenticity, integrity, and confidentiality of code and data. The Cortex-M23 is a compact, energy-efficient processor well-suited for constrained embedded applications. The highly configurable Cortex-M33 features a variety options including a coprocessor interface, digital signal processing and floating-point computation. Both new Cortex-M processors are backwards compatible with ARMv6-M and ARMv7-M architectures.

ARM System IP Optimized for Cortex-M Processors

ARM CoreLink SIE-200 is already licensed by ARM silicon partners and provides the interconnects and controllers that extend TrustZone to the system. The ARM CoreLink SSE-200 IoT subsystem reduces time to market by integrating Cortex-M33, CryptoCell, and Cordio radio along with software drivers, secure libraries, protocol stack, and the mbed OS.

IoT Connectivity

Connectivity is enhanced by next-generation ARM Cordio radio IP with Bluetooth 5 and 802.15.4-based standards ZigBee and Thread. Developers can choose from a standard radio implementation across a range of process nodes from multiple foundries. The Cordio architecture supports ARM and third-party RF.

Cloud-Based SaaS for Secure IoT Device Management

The ARM mbed IoT Device Platform has been expanded to include mbed Cloud, a new standards and cloud-based SaaS solution for secure IoT device management. Through mbed Cloud, OEMs can:

Simplify connection, provisioning, updating and securing of devices across complex networks
Enable faster scaling, productivity and time to market, allowing developers to use any device on any cloud
Enhance device-side capabilities with mbed OS 5, supported by a global community of 200,000 developers and more than 1 million device builds per month.

Implementation with IoT POP on TSMC 40ULP

Designers can quicken the development of SoCs featuring the latest Cortex-M processors with Artisan IoT POP IP now available for TSMC 40ULP process technology. ARM Artisan IoT POP IP enables low-power designs and optimizing for IoT applications.
