SECO develops a unique SMARC module for FuSa applications with Intel® Atom x6427FE and x6200FE processors

Safe operation is a top priority in the development of automated systems, machines and equipment, for example in industrial automation, transport or healthcare. Functional Safety (FuSa) of the applications is of central importance. This means design specifications that are based on various standards and aim to eliminate unacceptable risks in the event of a fault.

A new SMARC module is now available from SECO to help customers meet the FuSa requirement by combining the advantages of Smart Mobility ARChitecture (SMARC) modules with a range of functions geared towards FuSa applications. SMARC modules are compact standard Computer-On-Modules for projects that require high performance, small dimensions and low power consumption. SMARC supports up to four display interfaces and up to two Ethernet interfaces and have now become a standard for many IoT applications.

With the new SECO SMARC module HALLEY (former product name SM-C93), which is equipped with Intel® Atom x6427FE and x6200FE processors, OEMs can quickly develop FuSa-certified solutions. The advantage of the processors used is the integrated Safety Island, a functional safety IP that searches for, marks and reports errors and organizes diagnostic tests. Therefore, by using this module, even strict safety requirements can be met and solutions can be brought to market up to six months faster. HALLEY combines flexibility, reliability and safety in a single small module and offers a whole range of other FuSa-related functions. Customers can integrate the module into solutions and tailor it to their specific requirements.

Compared to creating custom hardware and software that must be individually certified to meet standards, the new SMARC module enables simple implementations and thus significantly shortens product developments. The integration of qualified FuSa components directly into the SMARC module and the complete documentation provided enables developers to pass through certification processes according to IEC 61508 and ISO 13849 more quickly, thus reducing development costs and time-to-market. HALLEY can be used in a wide range of applications, such as robotics, automated ground vehicles or industrial automation.

Safety functions of the SMARC module HALLEY overview

Using Intel's first processor platform optimised for IoT, SECO has integrated several security-enhancing features into the new SMARC module:

Functional safety features: FuSa interface signals for IEC 61508 and ISO 13849 (SIL2/Cat.3 PL d certified2, SIL3/Cat.4 PL e capable).

Integrated Intel® Safety Island: Intel® Safety Island, an integrated functional safety IP included on these processors, works with the CPU to check for errors, flag and report faults, and orchestrate diagnostic tests.

Intel® Time Coordinated Computing (Intel® TCC): With Intel® TCC and Time-Sensitive Networking (TSN), the HALLEY enables highly deterministic performance that standardizes time-sensitive data transmission.

In-band error-correcting code (IBECC): This error-correcting architecture works to detect and correct single-bit memory errors to enhance safety and reliability.

Wired connectivity: 2x integrated Ethernet controllers with TSN capabilities.

Industrial grade: Support for extended temperature operations at ambient temperatures of -40°C to 85°C.
