New ARM chips boost IoT security

The company said it intends to increase the rate at which IoT scales globally.

By Hannah Williams

ARM has introduced a new suite of security products for the Internet of Things (IoT), including processors, radio technology, subsystems, end-to-end security and a cloud-based services platform.

The company said the complete solution, which will secure data from the sensor to the service, is intended at increasing the rate at which IoT scales globally.

The new ARM Cortex-M23 and Cortex-M33 embedded processors based on the ARMv8-M architecture will bring ARM TrustZone to all IoT nodes.

The Cortex-M33 features configuration options such as a coprocessor interface, DSP and floating point computation, with increased performance and efficiency relative to Cortex-M3 and Cortex-M4.

The Cortex-M23 is aimed at taking security to the most constrained devices, acting as an ultra-low power microprocessor in a small footprint.

Both the Cortex-M processors are backwards compatible with ARMv6-M and ARMv7-M architectures.

The suite also includes a new range of ARM system IP optimised for the latest Cortex-M processors.

ARMThe ARM CoreLink SIE-200 offers the interconnects and controllers that extend TrustZone to the system, while the ARM CoreLink SSE-200 IoT subsystem reduces time to market by six to twelve months by integrating Cortex-M33, CryptoCell and Cordio radio along with software drivers, secure libraries, protocol stack and mbed OS.

For the radio technology, the company introduced the ARM Cordio radio IP with Bluetooth 5 and 802.15.4-based standards ZigBee and Threa.

Developers can select from a standard radio implementation across several process nodes from various foundries.

The Cordio architecture supports ARM and third-party RF. The Bluetooth and 802.15.4-based standards can be implemented individually or together

With respect to the cloud, the company expanded its ARM mbed IoT Device Platform to include mbed Cloud, a new standards and cloud-based SaaS solution for secure IoT device management.

mbed Cloud allows OEMs to simplify connection, provisioning, updating and securing of devices across complex networks.

They can scale faster and improve device-side capabilities with mbed OS 5, supported by a global community of 200,000 developers and over one million device builds a month.

The development and implementation of SoCs based on the latest Cortex-M processors can be accelerated with Artisan IoT POP IP, currently available for TSMC 40ULP process technology.

ARM Artisan IoT POP IP allows low-power designs and helps optimise IoT applications.

ARM executive vice president and president of product groups Pete Hutton said: “ARM partners shipped a record 15 billion chips last year, many destined for smart embedded applications.

“The IoT already runs on ARM but the goal now is scale, which we are enabling today through a uniquely comprehensive set of technologies and services built to work together seamlessly.”
