Low-Power Microcontroller with TrustZone Security
The Cortex-M processor series is designed to enable developers to create cost-sensitive and power-constrained solutions for a broad range of devices. Designed to meet the needs of tomorrow’s smart and connected embedded applications, Cortex-M23 is the smallest and lowest-power microcontroller with TrustZone security, making it the ideal processor for applications where software isolation and software security are required.
Internet of Things (IoT) Nodes
Energy-harvesting wireless sensor nodes use ambient energy as a power source where batteries or cables are not viable. Superior energy efficiency and the built-in TrustZone security make Cortex-M23 the ideal processor for use in maintenance-free, energy-harvesting IoT nodes and smart sensors.
Explore the Cortex-M23-based microcontrollers available today for designing secure applications.
The SAM L11 includes TrustZone for Armv8-M and boasts a rich feature set. The MCU series has an extremely low-power consumption, and a new capacitive touch feature with water tolerance and noise immunity.
The M2351 microcontroller brings a new level of trust and security to embedded systems. The MCU combines TrustZone, a secure attribution unit, an implementation-defined attribution unit, flash memory controller, and a security configuration unit.
