You may already know the Arm Musca-A, the first Platform Security Architecture (PSA) development platform with an Arm Cortex-M33 based subsystem, Arm TrustZone and reference architecture for Arm TrustZone-based systems. The board is a great tool to evaluate the IP and develop more secure software , so it’s no surprise that has been very popular amongst developers, with many design partners across the whole ecosystem using it as a reference to develop secure IoT chip designs.

We’re pleased to introduce our new board for the development of PSA ready IoT subsystems for Cortex-M, Musca-B1. Along with the elements of Musca-A, Musca-B1 has added Arm CryptoIsland and eFlash features for increased security assurance when it is needed. Security improvements are being driven by the risk of damaged reputations and the potential costs of any critical failure. Embedded systems increasingly have to manage sensitive data and applications such as payment services. With hacking on the increase, the natural concern is to address security as a system level concern.
