[Blog] Setting the Standard: Industry First PQC-Ready FPGA
Posted 10/13/2025 by Lattice Semiconductor
Quantum computing is no longer just a concept confined to research labs. Thanks to rapid progress in both hardware and algorithms, the risk to today’s cryptographic systems is steadily increasing. In 2025, Google’s 105-qubit Willow chip and Microsoft’s Majorana 1 processor demonstrated that scalable quantum systems are moving closer to practical reality. Industry experts now predict that quantum computers capable of breaking RSA-2048 encryption could arrive as early as 2030 to 2035. However, the threat is not limited to the future.
Attackers are using the “Harvest Now, Decrypt Later” (HNDL) strategy to prepare for the future, meaning they are collecting encrypted data today, with the intention of decrypting it once quantum technology matures. This makes it essential for organizations to begin adopting post-quantum cryptography (PQC) right away, ensuring that sensitive data remains protected for years to come.
For FPGA developers and engineers, this growing risk means that waiting is not an option. To service this immediate need, today, Lattice announced the industry’s first PQC-ready FPGA family, Lattice MachXO5™-NX TDQ, designed to help make this transition smooth by providing robust, future-ready security for control FPGAs.
MachXO5-NX TDQ: What Sets It Apart
The Lattice MachXO5-NX TDQ FPGA family delivers a complete, future-ready security platform. These devices combine quantum-resistant cryptography, crypto-agility, and robust hardware features in a single solution.
Comprehensive PQC and Classical Crypto Support
- Full suite of CNSA 2.0 and NIST-approved post-quantum cryptographic algorithms, including ML-KEM for key encapsulation, ML-DSA for digital signatures, and hash-based LMS/XMSS for secure code and firmware authentication.
- Backward compatibility with classical algorithms like AES256-GCM, SHA2/3, ECDSA, and RSA ensures seamless integration with existing systems.
Crypto-Agility for Evolving Threats
- Unique, patent-pending architecture allows in-field cryptographic algorithm updates, so your security can adapt as standards and threats evolve.
- Anti-rollback protection ensures only authorized, up-to-date algorithms are used.
Hardware Root of Trust and Secure Boot
- Trusted single-chip boot and unique device secret (UDS) provide a secure foundation for every deployment.
- Secure locking of SPI and JTAG interfaces prevents unauthorized access and tampering.
Flexible Key Management and Hybrid Security
- Supports up to 8 Key Authentication Keys (KAKs) and 2,048 Image Signing Keys (ISKs) per device, with independent revocation and algorithm flexibility for each key slot.
- • Hybrid cryptographic models allow classical and PQC algorithms to coexist, enabling layered security and smooth migration.
Quantum-Resistant Secure Channels and Authentication
- Hardware-based ML-KEM enables quantum-resistant key exchange and secure channel establishment, with support for multiple security levels.
- Least mean squares (LMS)-based bitstream authentication ensures only authorized firmware is loaded, with signing in certified hardware security modules (HSMs) and on-device verification.
End-to-End Platform Security
Seamless Integration and Real-World Readiness
- Supported by Lattice Radiant™ design software for easy adoption in new and existing projects.
- Designed for secure, AI-optimized datacenter, Industrial, and Communications infrastructure.
With its comprehensive suite of quantum-resistant and classical cryptographic features, the Lattice MachXO5-NX TDQ family stands out as the industry’s first secure control FPGA platform to deliver full CNSA 2.0-compliant PQC support, crypto-agility, and robust hardware root of trust. These technical benefits translate directly into real-world security, flexibility, and peace of mind for developers and organizations facing the next wave of cyber threats.
As quantum computing moves from concept to reality, the risks to traditional cryptography are accelerating. The MachXO5-NX TDQ family enables developers to stay ahead of these threats with hardware-based quantum-resistant key exchange, flexible key management, and seamless integration into modern infrastructure. Whether you are building secure datacenter systems, Industrial controls, or Communications platforms, these FPGAs provide the foundation for resilient, future-proof designs.
