Platform Secures Popular MCUs

Express Logic announces that its industrial-grade X-Ware IoT Platform now supports the TrustZone for ARMv8-M technology-based Microchip SAM L11 microcontrollers (MCUs). IoT devices almost always require an RTOS and network connectivity. As device vendors open their APIs to share data and allow more interoperability with other products and single-point devices and systems, information security and protection become significant issues. X-Ware IoT Platform provides a comprehensive and secure foundation that enables embedded developers using the SAM L11 microcontrollers to deliver more secure IoT devices.

 

Using the ARM TrustZone technology for ARMv8-M with the X-Ware IoT Platform, developers can achieve greater levels of security for their IoT devices. The ARMv8-M architecture enables the ThreadX RTOS to partition the application into trusted and non-trusted memory regions. Application code in a non-trusted region is confined to that region and thereby prevented from accessing any other region including the trusted region containing ThreadX.

 

The platform can create and schedule multiple threads for both trusted and non-trusted regions. Application code running in the non-trusted regions can access the full ThreadX API, with the approval of the application’s trusted code. The trusted application can disable any ThreadX API from access by non-trusted code.

 

In addition to the solution’s security advantages, the platform and its components carry safety certifications that include IEC 61508 SIL 4, IEC 62304 Class C, ISO 26262 ASIL D, EN 50128 SW-SIL 4, UL 60730-1 Annex H, CSA E60730-1 Annex H, IEC 60730-1 Annex H, IEC 60335-1 Annex R, and IEC 60335-1 Annex R, UL 1998.
