ARM summarises its campaign as “accelerating secure IoT from chip to cloud”. Enabling the IoT revolution, ARM says, needs efficiency – devices will need to be battery powered or run from energy harvesting – security, to protect data from sensor to cloud, and scale. The package of product and services includes;
- two specific Cortex-M processors based on the ARMv8-M architecture, to be known as M23 and M33, which come with ARM's TrustZone technology;
- IP to build an IoT subsystem on custom SoC designs: the CoreLink SSE200 , with ARM CoreLink system IP for, the company asserts, the fastest, lowest-risk path to silicon;
- secure SoC designs that embody ARM's TrustZone CryptoCell technology;
- a wireless solution with ARM Cordio radio IP for IEEE802.15.4 (ZigBee and Thread) and Bluetooth 5. time of introduction, ARM has collaborated with foundry TSMC to offer an optimized implementation on ARM Artisan IoT POP IP, for TSMC's 40ULP process. ARM says that 40 nm, while some way behind today's leading edge, is likely to be the “sweet spot” process in which IoT chips are built.
ARM says that this release is its most comprehensive product suite ever, intended to deliver new levels of security, efficiency, low-power connectivity and device life cycle management, adding, “..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.”
Bringing TrustZone to Cortex-M processors, and to resource-limited IoT nodes, the Cortex-M23 and Cortex-M33 are the first embedded processors based on the ARMv8-M architecture. The majority of the top ten global MCU suppliers have already licensed one or both processors. Lead partners include Analog Devices, Microchip, Nuvoton, NXP, Renesas, Silicon Labs and STMicroelectronics.
Cortex-M33 has configuration options including a coprocessor interface, DSP and floating point computation, with increased performance and efficiency relative to Cortex-M3 and Cortex-M4. In
