Musca-B1 Test Chip Board
Musca-B1 is a test chip and Platform Security Architecture (PSA) development platform for IoT subsystems. In addition to the Arm Cortex-M33 based subsystem, and reference architecture for Arm TrustZone-based systems, it has added eFlash features for increased security assurance.
Key benefits include:
- Used as a PSA development platform
- Arm Cortex-M33 based subsystem, with Arm TrustZone
- Built with Corstone-201 foundation IP
- Embedded Flash Memory

About Musca-B1
Musca-B1 makes integration of various IP and designing security into your products easier. It not only implements the recommendations of PSA, but also demonstrates Arm IP for evaluation purposes and provides a reference implementation that can be reused in SoC products.
Musca-B1 incorporates CryptoCell, allowing SoC designers to prototype different use cases for either one to serve as a root of trust. It has embedded flash to improve security and better represent a real-world device. Using the latest flash memory controller, it utilizes the Global Flash Bus (GFB) standard.
Musca-B1 is also a software development platform. It has four times the RAM of Musca-A, allowing software developers to not be hindered by memory constraints.
