Develop IoT End Points Faster

The Musca-A1 test chip board is a reference implementation of an Arm TrustZone system that helps you get IoT security right, from the start. It implements the recommendations of the Platform Security Architecture and can be used to prototype secure software.

Features and Benefits
Hardware Support for Security

The Arm Musca-A1 test chip is built from several available Arm IP components, including Cortex-M33 processor, Corstone-200 foundation IP, CoreSight SoC-400M debug, and CryptoCell-312.

A Software Development Platform

Musca-A1 is also a software development platform so developing secure software is now easier. Arm even uses it to develop the PSA trusted firmware, making it very easy to port to any device built on the same architecture.

PSA Ready

The test chip architecture implements the Platform Security Architecture (PSA) — the platform of choice for secure IoT devices — and has already been tried and tested by internal Arm software teams and Arm partners.

Armv8-M Reference System

The subsystem architecture at the heart of the Musca-A1 test chip, is used by all the ecosystem surrounding the Armv8-M processors and expands the Arm TrustZone isolation outside of the processor, throughout the system.

Security in Depth

Isolation is the secret to security. Beyond Root-of-Trust, the Arm CryptoCell IP provides additional security for key handling, lifecycle management, encryption, authentication and many other crypto services.

High Performance as Needed

Having a fast processor active all the time is inefficient. The subsystem at the heart of the Musca-A1 test chip ensures that high performance is available when you need it, but doesn’t consume energy when you don’t.
