Build a Secure System-on-Chip for Mainstream and Constrained IoT Devices

The Arm Corstone-201 reference package contains many elements to help SoC designers build secure systems faster. It includes three subsystems, based on Arm Cortex-M3, Cortex-M23 andCortex-M33 processors, that provide a solid base for either mainstream or constrained SoC design.

Features and Benefits

Fast Time to Market

Save engineering work that could be invested in differentiation. Corstone-201 integrates processor and security IP, together with the most relevant system components, to form a verified system that is configurable and modifiable.

Security Built-in 

Speed up time to security and reduce risk with Corstone-201, designed according to Platform Security Architecture (PSA) principles. Add security IP such as Arm CryptoCell to an Arm TrustZone enabled system.

Reduce Costs

SoC designers can benefit from reduced development costs, as well as out-of-the-box testbenches, extensive resources and the ability to reuse the same Corstone design for several SoC variations.
