Lattice Mach-N2 Turns the Post-Quantum Procurement Gate Into an FPGA Moat

Publication Date: September 21, 2026

Lattice Semiconductor announced the Mach-N2 secure control FPGA family and the Lattice Prompt AI design tool. Mach-N2 combines up to 220K system logic cells with what Lattice presents as the only full CNSA 2.0-compliant post-quantum cryptography suite among small FPGAs, while Prompt connects agentic coding tools to the Lattice design flow through open MCP. The pairing defends the secure control franchise in a year when post-quantum mandates convert security from a feature into a procurement gate.

What Is Covered in This Article:

• Lattice Mach-N2 secure control FPGAs on the Nexus 2 platform with 65K to 220K system logic cells, 350 MHz fabric performance, PCIe 4.0, 10G Ethernet, and 16 Gbps SerDes
• Full CNSA 2.0-compliant post-quantum cryptography including ML-DSA, LMS, and XMSS authentication, ML-KEM key exchange, and field-updatable crypto agility
• Integrated 128 Mb to 256 Mb configuration flash with sub-30 ms instant-on boot and up to three stored recovery images
• Lattice Prompt, a free AI FPGA design tool linking agentic IDEs and LLMs to Lattice Radiant via open MCP with vendor-reported productivity gains of 10x or more
• Competitive mapping against AMD, Altera, Microchip, Efinix, and Achronix across configuration memory, security claims, process node, and I/O
