In response to emerging cybersecurity challenges and evolving cryptographic standards, Microchip Technology (Nasdaq: MCHP) has unveiled the MEC175xB family of embedded controllers featuring hardware-embedded post-quantum cryptographic support. This development supports the US National Security Agency’s Commercial National Security Algorithm Suite 2.0 (CNSA 2.0), which outlines standards for quantum-resistant cryptography and calls for post-quantum readiness within the next two years across computing and data center infrastructure.
The MEC175xB controllers are designed for standalone operation and adopt a modular architecture that enables seamless integration of post-quantum cryptographic methods without compromising legacy functionality. These low-power devices incorporate National Institute of Standards and Technology (NIST)-approved cryptographic algorithms, secure boot configurations, and Enhanced Serial Peripheral Interface (eSPI) capabilities to meet modern security demands.
The controllers implement CNSA 2.0-compliant algorithms in immutable hardware, including Module-Lattice-Based Digital Signature Algorithms (ML-DSA), Merkle-based Leighton-Micali Signatures (LMS), and Module-Lattice-Based Key-Encapsulation Mechanisms (ML-KEM). These hardware-based implementations are designed to eliminate vulnerabilities present in software-based systems.
Additional features include secure boot and firmware update mechanisms that support CNSA 1.0, CNSA 2.0, or hybrid signature verification. Attestation functionality is supported via ML-DSA, enhancing system integrity and identity verification. Powered by an Arm® Cortex®-M4F processor operating at 96 MHz, the MEC175xB also features a Memory Protection Unit (MPU), 480 KB of SRAM, I3C® host/client interfaces, and an optional USB 2.0 Full-Speed interface to support diverse application requirements.
The MEC175xB family addresses the growing need for quantum-resilient embedded solutions, offering long-term data security in a flexible and power-efficient design suitable for next-generation connected systems. With over six decades of experience in the aerospace field, Microchip continues to support the industry with an extensive catalog of components, including microcontrollers, FPGAs, power systems, and timing solutions—each engineered to meet rigorous military and spaceflight standards.
