TrustZone for Armv8-M (for Cortex-M profile) The Security Extension, marketed as TrustZone for Armv8-M Technology, was introduced in the Armv8-M architecture. No-execute page protection. As of Armv6, the Arm architecture supports no-execute page protection, which is referred to as XN, for eXecute Never. Arm TrustZone technology is a system-on-chip (SoC) and CPU system-wide approach to security with hardware-enforced isolation to establish secure end points and a device root of trust. TrustZone for Cortex-A Processors TrustZone for Cortex-M Processors TrustZone Security System IP Arm Microcontroller Security with TrustZone-M Standard Level - 2 days view dates and locations. With the ever increasing range of applications for Arm® microcontrollers, from simple environmental monitors, through to automotive components and complex consumer appliances, the issue of security when developing these devices has never been so crucial. Oct 10, 2018 · This is one of the first Cortex-M processors with Arm TrustZone security technology, bringing a new level of trust to embedded systems. These new NXP microcontroller families represent the next generation of Cortex-M based design, familiar to thousands of developers and used in millions of designs. What was released by NXP? The ARM Cortex-M is a group of 32-bit RISC ARM processor cores licensed by Arm Holdings. These cores are optimized for low-cost and energy-efficient microcontrollers, which have been embedded in tens of billions of consumer devices. The cores consist of the Cortex-M0, Cortex-M0+, Cortex-M1, Cortex-M3, Cortex-M4, Cortex-M7, Cortex-M23, Cortex-M33, Cortex-M35P, Cortex-M55. A Cortex-M processor with physical security features and optional software isolation using TrustZone for Armv8-M.
