Plastic Labs announced the very first Arm Cortex-M33 based low power wireless platform with support for Bluetooth 5.1, Zigbee 3., Thread and multiprotocol connectivity. The brand new Wireless Gecko Series 2 platform includes system-on-nick (SoC) devices, software and tools made to make Internet of products (IoT) products more effective, secure and reliable. The very first products within the Series 2 portfolio include EFR32xG21 SoCs that contain 512KB to 1024KB Flash, 64 to 96KB RAM, along with a wealthy suite of digital and analog peripherals. Additionally towards the high-performance radio, the Series 2 SoCs offer new improved security measures according to an on-nick dedicated security core and also the Arm Cortex-M33 processor with Arm TrustZone technology. TrustZone has turned into a requirement to supply hardware isolation in connected, upgradeable IoT devices which store private information for example keys, certificates and private data.
Improvements
The main and peripheral options that come with the EFR32xG21 are described below:
Target applications
The EFR32xG21 SoCs target an array of applications having a high-performance radio that supports multiprotocol connectivity and many popular protocol options. The brand new Bluetooth 5.1 stack offers four occasions the number, double the amount speed and eight occasions the broadcasting message capacity of Bluetooth 4., growing the functionality of Bluetooth for that IoT. The SoCs also support Bluetooth mesh to allow greater coverage in applications, for example commercial lighting.
With support for Thread and Zigbee 3., the EFR32xG21 SoCs reveals much more smart and connected applications in homes, structures, industrial, retail, health insurance and metering.
Arm TrustZone for IoT devices
The EFR32xG21 SoCs are the initial Wireless Gecko products to include Arm TrustZone technology, enabling IoT devices to become constructed with security in the ground-up.
Listed here are the 4 key features of an IoT device that needs isolation and greater performance, enabled by Cortex-M33 with TrustZone:
1. Connected
IoT devices could be attached to the internet directly via Wi-Fi, Ethernet or gateways that support Bluetooth, Zigbee or Thread. This presents an chance for malicious interception of the communication or remote software attacks. Prevention can be done with the proper hardware isolation from the file encryption and security-related functions in the application code.
2. Upgradable
Among the best options that come with modern IoT devices is the opportunity to upgrade the firmware remotely. The firmware upgrade can enable or unlock additional features or perhaps patch security vulnerabilities. Upgradability is excellent but care must automatically get to any upgrade safely. Again, the very best means to fix implement a safe and secure firmware upgrade is as simple as utilizing hardware isolation.
3. Valuable information
Most IoT devices need to store secret information for example keys for file encryption, certificates for firmware upgrades and Wi-Fi passwords. Additionally, IoT devices might also store biometric and private information and also the firmware is also valuable. Hardware isolation enables all the private assets to become stored, safely isolated in the user application.
4. More performance
Plastic Labs announced the very first Arm Cortex-M33 based low power wireless platform with support for Bluetooth 5.1, Zigbee 3., Thread and multiprotocol connectivity. The brand new Wireless Gecko Series 2 platform includes system-on-nick (SoC) devices, software and tools made to make Internet of products (IoT) products more effective, secure and reliable. The very first products within the Series 2 portfolio include EFR32xG21 SoCs that contain 512KB to 1024KB Flash, 64 to 96KB RAM, along with a wealthy suite of digital and analog peripherals.

Hardware isolation enables all the private assets to become stored, safely isolated in the user application.
4. More performance
The Cortex-M33 processor utilized in Series 2 devices offers a 20% performance increase within the Arm Cortex-M4 processor utilized in previous-generation Wireless Gecko devices. The additional performance may be used to include more features, run multiple RF protocols concurrently or reduce power by running in a slower clock speed.
Isolation
We, therefore, need hardware-enforced isolation between Reliable and Non-reliable areas of the machine. Using the Cortex-M33 processor and TrustZone technology, hardware isolation could be implemented in one processor with two views. TrustZone provides the best means to fix implement secure IoT systems today.
The Arm Cortex-M33 processor: security, efficiency, and ease-of-use
The Cortex-M33 is made for feature-wealthy IoT and embedded products. It extends the capacity from the Cortex-M3 and Cortex-M4, supplying more security, enhanced efficiency, performance and scalability for deployment even just in probably the most demanding contexts.
TrustZone technologies are already deployed in vast amounts of devices and it is now available for Cortex-M within our Armv8-M architecture with similar, proven, system-wide security concept, but enhanced for embedded, deterministic devices.
The Cortex-M33 also adds high-performance Digital Signal Processing (DSP) extensions along with a effective Floating-Point Unit. With computing relocating to the advantage the opportunity to process complex signals and do complex control in your area reduces latency, communications overhead and power consumption.
The Cortex-M33 processor brings TrustZone security to demanding and occasional-powered devices, enabling programmers to utilize a familiar programming model to create software isolation more achievable. The processor props up primary recommendations in the Platform Security Architecture (PSA), that is a framework supplying a typical method of to safeguard both software and hardware. PSA provides a consistent foundation for designers and developers focusing on IoT and embedded devices.
The PSA documentation and free code (Reliable Firmware-M) is perfectly positioned for developers using CPUs such as the Cortex-M33 processor.
