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.

Features and Benefits
Solid Foundations

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.

Secure Software Development

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.

PSA Ready

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.

Elevated Security

In addition to the Root-of-Trust and CryptoCell IP, CryptoIsland and eFlash have been added to Musca-B1 to provide extra security.

Key to Armv8-M

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.

High Performance as Needed

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.

A Reference Design
Musca-B1 also features elements coming from various IP providers, that complement the Arm IP to form a more complete solution. These providers have partnered with Arm to combine their IP with Arm IP, which can benefit design teams who would need to integrate similar IP in the future. The following elements have been incorporated into Musca-B1:  
  • A PMU from Dolphin Integration 
  • Embedded Flash from TSMC 
  • Various interface peripherals from Cadence 
  • A low-power PLL from Silicon Creations
