Microchip release first Arm Cortex-M23 based chip bringing new levels of security for constrained IoT devices


Jul. 12, 2018 – 

Imagine a future of one trillion connected devices around the globe – in our cars, homes, hospitals, workplaces, streets. Well, everywhere. How do we ensure that even the most tiny, low-power devices authenticate users, ensure personal information is encrypted and maintain enough battery life to do all of that efficiently and securely?

It is only with semiconductor, systems and software companies adopting more secure technology will we see more secure devices entering the market. Microchip announced the first chip families available based on the Arm Cortex-M23 processor – the SAM L11 and the SAM L10 – with the SAM L11 based on TrustZone for Armv8-M, bringing a new level of trust and security to embedded systems. Since this chip is based on the familiar Cortex-M programming model, security is now even more accessible for embedded software developers. This technology enables product manufacturers to ensure a trusted foundation at the core of their most constrained devices, bringing robust protection for the valuable data being collected by even the smallest IoT devices.

Where will we see the impact?

Appliances are rapidly adding more intelligence and being connected to the Internet. TrustZone technology enables software isolation on the Cortex-M23, delivering the required level of foundational security for even the smallest embedded and connected IoT devices and preventing malicious access.
