Your Toolbox for Secure Mainstream and Constrained IoT Solutions

The Arm Corstone-201 foundation IP makes an ideal starting point for SoC design. It contains a subsystem and system IP to complement Cortex-M processors, including the latest Cortex-M23 and Cortex-M33 processors.

The Corstone-201 foundation IP incorporates the Arm SSE-200 subsystem for Cortex-M33 and the SSE-123 example subsystem built around the Cortex-M23. The subsystems provide a solid base for either mainstream or constrained device SoC design, using the latest Cortex-M processor, with Arm TrustZone support for deep-rooted security.

Features and Benefits
Pre-Integrated Security Elements

Proven filters to protect memory, peripherals, and enforce access rules at a system level are pre-integrated and ready to use. Other security IP, like CryptoCell or CryptoIsland, are easy to connect, and a TRNG is also included.

Build Firmware Quickly and Efficiently

Arm provides open-source permissive licensed Corstone ready software elements. To bring a solid foundation to secure applications, Trusted Firmware-M is ready to run on the SSE-subsystem. You have many options to start your development: either with Fast Models or with the MPS2 and MPS3 FPGA prototyping boards with subsystems’ images.

Superset of Corstone-200 Foundation IP

Many new elements have been added to the very successful Corstone-200 toolbox, including the SSE-123 subsystem, CoreSight SoC-400M, CoreLink GFC-100 and GFC-200 flash controllers, SDC-600 secure debug controller and PCK-600 power control kit.

Use Cases
Where Innovation and Ideas Come to Life

Asset and inventory management, both in store and in the warehouse. Allows accurate tracking and protection against theft, localized advertisement via IoT beacons, and options for smart product packaging.
