Lattice Semiconductor has launched MachXO5-NX TDQ, the industry’s first secure control FPGA platform with full CNSA 2.0-compliant post-quantum cryptography, crypto-agility, and hardware Root of Trust. It targets compute, communications, industrial, automotive, and AI-optimized datacenter applications.
What is Covered in this Article:
- Launch of Lattice MachXO5-NX TDQ with CNSA 2.0-compliant PQC support and hardware Root of Trust.
- Full suite of PQC and classical algorithms for hybrid cryptographic protection.
- Advanced key management and anti-rollback capabilities for evolving security standards.
- Expansion of the MachXO5-NX family to address emerging quantum security threats.
The News: Lattice Semiconductor has introduced the MachXO5-NX TDQ FPGA family – the first secure control FPGA platform offering full CNSA 2.0-compliant post-quantum cryptography and a built-in hardware Root of Trust. It integrates NIST-approved algorithms like LMS, XMSS, ML-DSA, ML-KEM, AES256-GCM, SHA2, SHA3, and SHAKE, bringing quantum-resistant security to Computing, Communications, Industrial, and Automotive markets.
The company is showcasing the device at the OCP Global Summit (October 14-16, 2025, in San Jose). The MachXO5-NX TDQ is already available and shipping to Communications and Compute customers, supported by the latest Lattice Radiant software.
Lattice Launches New FPGA for Quantum Security
Analyst Take: The MachXO5-NX TDQ launch marks a key step forward in FPGA security. By merging CNSA 2.0-compliant PQC, crypto-agility, and hardware Root of Trust, Lattice aims to offer platform security in the quantum era. Features like authenticated bitstreams, flexible key management, and strong side-channel defenses show a well-integrated design built for next-generation infrastructure.
Comprehensive PQC Integration
MachXO5-NX TDQ supports a complete lineup of CNSA 2.0 and NIST-approved post-quantum algorithms, including LMS, XMSS, ML-DSA, and ML-KEM, along with AES256-GCM, SHA2, SHA3, and SHAKE. These enable secure bitstream authentication, encryption, and post-quantum key exchange. Hardware-based ML-KEM ensures quantum-safe channel creation, while LMS and XMSS verify bitstream integrity and authenticated firmware loading. This full PQC integration signals a major shift in FPGA security, positioning MachXO5-NX TDQ as a strong defense platform against quantum-powered attacks.
Crypto-Agility and Secure Lifecycle Management
The platform includes patent-pending crypto-agility with in-field algorithm updates and anti-rollback version control. It supports up to 8 Key Authentication Keys and 2,048 Image Signing Keys per device, each with independent revocation. Hybrid cryptography allows PQC and classical algorithms to work together for layered security. With SPDM 1.4 and hybrid PFR support aligned with NIST SP 800-193, the device provides a flexible framework for changing standards-helping it stay relevant as security demands evolve.
Hardware Root of Trust and System Integrity
MachXO5-NX TDQ features a trusted single-chip boot, unique device secret (UDS), and non-volatile configuration memory with secure partitioning. Lockable SPI and JTAG interfaces, side-channel protection, and NIST CAVP-certified algorithms strengthen overall defense. Support for DICE, SPDM, and SupplyGuard adds further protection for supply chain and lifecycle security. Together, these create a trusted foundation for system-wide integrity from startup to runtime.
Secure Control FPGA Platform Scalability
Built on the Nexus platform, MachXO5-NX TDQ offers up to 100K logic density, 7.3 Mb internal memory, 55 Mb user flash, and up to 378 I/O pins, with PCIe Gen2 on select models. It maintains low power consumption while supporting LVDS, MIPI, and PCIe interfaces for board management. The release also includes MachXO5-NX TD variants with higher density and more package options. This scalability makes it well-suited for compute, communications, industrial, automotive, and AI datacenter uses, supporting complex control systems that demand strong security.
What to Watch:
- How the adoption of PQC-ready secure control FPGAs align with the upcoming CNSA 2.0 compliance timelines.
- Implementation of in-field crypto-agility for evolving post-quantum standards.
- Deployment of MachXO5-NX TDQ in communications and compute environments following its initial availability.
- Broader competitive responses from other FPGA vendors targeting post-quantum security.
