MYC-LF25X: Built-in Full-Stack Security for Seamless CRA & IEC 62443 Compliance

As cybersecurity threats intensify, new regulations are redefining compliance for equipment manufacturers. The EU's Cyber Resilience Act (CRA) and the industrial security standard IEC 62443 have made security a non-negotiable foundation of product design, no longer just an option.

To address this critical industry need, MYIR introduces the MYC-LF25X System-On-Module. Built on STMicroelectronics' STM32MP257F processor, which has achieved SESIP Level 3 certification and delivers a full-stack, verifiable security architecture. From a hardware-based Root of Trust to application-level protection, every layer is purpose-built to mitigate risks and simplify compliance. The MYC-LF25X provides developers with a robust and efficient solution for creating safety-critical applications that meet international regulations and industry standards, accelerating time-to-market without compromising security.

1. The Foundation of Compliance: Why the MYC-LF25X is Your Smart Choice?

The CRA mandates that connected products must feature "built-in security," manageable vulnerabilities, and sustainable update capabilities. The IEC 62443 standard, particularly IEC 62443-4-2 (Component Safety Requirements), provides a concrete, actionable technical framework for achieving these objectives. The design and ecosystem of MYC-LF25X directly address these core requirements:

Hardware-Based Trust Anchor

At the heart of the MYC-LF25X lies the STM32MP257F processor, which is certified to SESIP Level 3. This means its hardware and Root of Trust firmware have undergone rigorous white-box vulnerability analysis by independent laboratories, providing a solid foundation for your product's overall certification (e.g., for CRA, RED) and significantly simplifying the compliance process.

Security Features Mapped to Standards

Every security feature of the MYC-LF25X is designed with IEC 62443-4-2 in mind. The module's capabilities directly map to key Component Requirements (CR) and Embedded Device Requirements (EDR), transforming compliance from a theoretical paper exercise into a practical, implementable reality. This alignment helps manufacturers build certified products faster, with confidence.

3. Choose the MYC-LF25X, Get Far More Than Just a Chip

Choosing the MYC-LF25X means selecting a certified, ecosystem-ready security foundation.

1) Accelerated time-to-market: 

Pre-integrated security features and automated toolchain (STM32CubeProgrammer, Yocto) dramatically reduce the development cycle for in-house security infrastructure.

2) Reduces Risk & Cost: 

The SESIP Level 3 certified hardware foundation streamlines end-product certification, while the mature SSP solution ensures long-term protection of your production investment.

3) Trust That Lasts: 

With an architecture built on open standards like OP-TEE and secure OTA updates, your product stays maintainable and adaptable across its entire lifecycle.

In an era when cybersecurity compliance is a market entry requirement, the MYC-LF25X gives you a strategic head start. By embedding security at the hardware level, this comprehensive solution integrates the STM32 Trust framework, meets IEC 62443 technical specifications, and upholds the legislative intent of the CRA. Choose the MYC-LF25X as the trusted core for your next-generation smart devices and turn compliance complexity into confidence, so you can focus on delivering greater product value.
