Insights
Microchip's quantum-resistant controllers establish strategic positioning in critical security infrastructure as quantum computing threats loom.
Microchip Technology's new MEC175xB controllers represent a significant strategic advancement in the embedded security landscape. The timing is particularly notable as the NSA's two-year timeline for quantum-resistant implementation creates an immediate market opportunity. The controllers incorporate three NIST-standardized post-quantum cryptographic algorithms (ML-DSA, LMS verification, and ML-KEM) implemented in immutable hardware—a critical distinction from software implementations that remain vulnerable to certain attack vectors.
The hardware-based approach offers superior security against side-channel attacks while the immutable implementation prevents tampering—advantages that provide meaningful differentiation in high-security environments like government and financial infrastructure. The modular design allows gradual adoption of quantum-resistant technology without disrupting existing systems, lowering implementation barriers for security-conscious enterprises facing compliance deadlines.
What separates these controllers from conventional embedded security is their flexibility in supporting both current CNSA 1.0 and future CNSA 2.0 cryptographic standards through configurable secure boot solutions, enabling organizations to migrate gradually rather than requiring disruptive overhauls. The Arm Cortex-M4F architecture with 96MHz clock speed and 480KB SRAM provides sufficient computational resources for complex cryptographic operations without excessive power consumption—critical for applications with strict energy constraints.
The early adopter program suggests Microchip is positioning these controllers for specialized high-security applications first, creating reference implementations before broader market deployment. With quantum computing threats accelerating faster than many cybersecurity roadmaps anticipated, Microchip's hardware-based quantum resistance represents valuable intellectual property and potential competitive advantage in securing future computing infrastructure.
The MEC175xB family features post-quantum cryptography, enhanced security features and low power consumption
CHANDLER, Ariz., May 15, 2025 (GLOBE NEWSWIRE) -- Driven by advancements in cryptographic research and the need for stronger security measures, the National Security Agency (NSA) introduced the Commercial National Security Algorithm Suite 2.0 (CNSA 2.0) to establish a set of quantum-resistant cryptographic standards. The NSA is now urging data center and computing markets to become post-quantum ready within the next two years. To help system architects meet evolving security demands, Microchip Technology (Nasdaq: MCHP) has developed its MEC175xB embedded controllers with embedded immutable post-quantum cryptography support.
As a standalone controller, the MEC175xB family employs a modular approach for developers to efficiently adopt post-quantum cryptography, helping ensure long-term data protection without compromising existing functionality. These low-power controllers are designed with National Institute of Standards and Technology (NIST) approved post-quantum cryptographic algorithms, configurable secure boot solutions and an advanced Enhanced Serial Peripheral Interface (eSPI).
“As the significance of potential, future attacks on cryptography using quantum computing is understood more widely, the cybersecurity landscape is already undergoing substantial transformations,” said Nuri Dagdeviren, corporate vice president of Microchip’s security products business unit. “Our MEC175xB controllers, featuring quantum-resistant cryptography implemented in immutable hardware with efficient power management, are designed to equip our customers with the tools they need to navigate increasingly complex digital security requirements.”
MEC175xB controllers incorporate CNSA 2.0-compliant Module-Lattice-Based Digital Signature Algorithms (ML-DSA), Merkle stateful hash-based Leighton-Micali Signature (LMS) verification and Module-Lattice-Based Key-Encapsulation Mechanism (ML-KEM) standardized by NIST. These new algorithms with quantum attack resistance are implemented in immutable hardware to block attack paths possible on software implementations.
The controllers feature secure boot and secure firmware update schemes configurable to use either CNSA 1.0 or 2.0 or hybrid-based signature verification. Attestation capabilities use ML-DSA for signing and key generation to enhance system integrity and authenticity. At the core is an Arm® Cortex®-M4F processor with a Memory Protection Unit (MPU) running at 96 MHz to deliver high performance for complex computations and real-time applications. The controllers include 480 KB of SRAM, I3C® host and client interfaces and an optional USB 2.0 Full-Speed interface for versatile connectivity.
