Express Logic: X-Ware IoT platform supports SAM L11 microcontrollers

Express Logic has announced that its industrial-grade X-Ware IoT Platform – powered by ThreadX RTOS – now supports the TrustZone for ARMv8-M technology-based Microchip SAM L11 microcontrollers. Using the ARM TrustZone technology for ARMv8-M with Express Logic’s X-Ware IoT Platform, developers can achieve new 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. ThreadX for ARMv8-M is able to 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 X-Ware IoT Platform, ThreadX, FileX, and NetX Duo have attained the highest level of safety certifications. They 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.
