Faster Development with More Security
The Musca-B1 test chip board is an evaluation platform to develop PSA ready IoT Subsystems for Cortex-M, based on the Armv8-M architecture. It is built on the Platform Security Architecture (PSA) principles and introduces additional security features, such as CryptoIsland and eFlash.
The Arm Musca-B1 test chip is built from several available Arm IP components, including Cortex-M33 processor, Corstone-200 foundation IP, CoreSight SoC-400M debug, GFC-100 flash controller, CryptoCell-312 and CryptoIsland-300.
Musca-B1 can also be used to prototype secure software. Arm and its partners use it to develop and contribute to the PSA Trusted Firmware-M, making it very easy to port to any device built on the same architecture.
The test chip architecture integrates the recommendations of Platform Security Architecture (PSA) and has already been tried and tested by internal Arm software teams and Arm partners.
In addition to the Root-of-Trust and CryptoCell IP, CryptoIsland and eFlash have been added to Musca-B1 to provide extra security.
The subsystem architecture at the heart of the Musca-A and Musca-B1 test chips is used by all the ecosystem surrounding the Armv8-M processors and expands the Arm TrustZone isolation outside of the processor, throughout the system. It is provided by the SSE-200 subsystem, which is ready to be used to form the core processing element of mainstream IoT devices.
Having a fast processor active all the time is inefficient.
The subsystem at the heart of the Musca-B1 test chip uses two asymmetrical cores to ensure that high performance is available when you need it, but doesn’t consume energy when you don’t.
