Lattice Semiconductor introduced the Mach-N2 secure control FPGA family, offering up to 220K system logic cells alongside what the company presents as the only full CNSA 2.0-compliant post-quantum cryptography suite available in a small FPGA. This combination positions Mach-N2 to capitalize on an emerging procurement shift, as new national security system acquisitions face a January 1, 2027 deadline for quantum-resistant signing. Lattice reported Q2 FY 2026 revenue of $201.1 million, up 62.2% year over year, and Compute and Communications revenue of $126.0 million growing 83.
Mach-N2 Achieves Full CNSA 2.0 Compliance for Post-Quantum Security
The Lattice Mach-N2 family fully complies with the CNSA 2.0 standard, a benchmark for post-quantum cryptography, and delivers a complete algorithm suite for device protection alongside user-callable services for firmware authentication and encryption. This distinction separates Mach-N2 from competitors currently outlining plans for compliance, as Lattice asserts it has both the complete algorithm set implemented in hardware and the programmable quantum-resistant cryptographic services available to users at runtime.
Algorithms within the Mach-N2 are field-updatable with anti-rollback protection, allowing deployed systems to adapt to revisions from the National Institute of Standards and Technology without requiring a hardware redesign. Lattice claims this capability is verifiable through competitor documentation, a statement supported by analysis from Futurum. The Mach-N2, built on the Lattice Nexus 2 platform, offers system logic cell counts ranging from 65K to 220K system logic cells, and integrates non-volatile flash memory alongside a hardware Root of Trust.
A 220K system logic cell device can fully configure in under 30 milliseconds from on-chip flash, a speed critical for rapidly deploying secure systems. This performance is enabled by PCIe 4.0, 10G Ethernet, and 16 Gbps SerDes connectivity, facilitating integration with host processors and high-bandwidth data streams. The family’s compliance with CNSA 2.0 encompasses ML-DSA, LMS, and XMSS authentication protocols, as well as ML-KEM key exchange, providing a comprehensive suite of post-quantum security features.
Lattice is demonstrating the Mach-N2 alongside AMI platform firmware in rack-scale designs at the OCP Global Summit, showcasing its integration potential in large-scale deployments, the company says. Independent developers are also evaluating Lattice Prompt, a free AI FPGA design tool, with reports indicating productivity gains of ten times or more on production designs.
Lattice Prompt links agentic coding tools and large language models to the Lattice design flow, potentially disrupting traditional FPGA development timelines and accessibility. Whether these gains are broadly replicated remains to be seen, but the initial results suggest a significant shift in FPGA design methodology.
Integrated On-Chip Flash Secures Mach-N2 Against Bitstream Attacks
Embedding configuration flash directly into the silicon defines the competitive positioning of the Mach-N2 family, blocking physical access to the bitstream and user flash memory design. This internal locking mechanism allows the JTAG and configuration ports to be secured from within the device itself, a feature absent in many competing field-programmable gate arrays. Upon detecting tampering, the anti-tamper module can zeroize encryption keys, clear configuration random-access memory, or permanently disable the device, adding a critical layer of physical security.
This performance contrasts with similarly sized AMD Artix and Spartan UltraScale+ parts, which require approximately 250 milliseconds to configure, based on figures compiled from published user guides. Microchip PolarFire is the only other part utilizing secure on-chip non-volatile memory, while Efinix Titanium employs a co-packaged system-in-package die for integrated flash. AMD, Altera, and Achronix devices rely entirely on external flash for configuration, leaving the bitstream vulnerable during each power cycle.
Beyond security, Mach-N2 expands the input/output capabilities of non-volatile FPGAs, incorporating PCIe 4. This places the device above the PCIe Gen 2 range traditionally occupied by control FPGAs, bringing it closer to the Gen 4 mainstream and enabling its use as a companion chip to modern system-on-chips, according to Lattice. While AMD’s Versal Premium Gen 2 currently leads in performance with PCIe Gen 6 and CXL 3. 1, and Achronix Speedster7t operates at Gen 5, the Mach-N2 offers a compelling balance of security and connectivity.
Lattice acknowledges that AMD or Altera could publish fuller claims on existing devices before the 2027 deadline, but emphasizes the current advantage in integrated security features. Lattice reports that the Mach-N2 spans 65K to 220K system logic cells across five devices, adding a hardware Root of Trust and CNSA 2. 0-compliant post-quantum cryptography.
The inclusion of crypto agility is intended to support system control and security in compute, communications, and industrial infrastructure.
Lattice Prompt AI Toolstreamlines FPGA Design with Open MCP
This connection reportedly delivers productivity gains of ten times or more, a claim based on internal vendor testing and suggesting a potentially disruptive shift in FPGA development speed and accessibility. The tool supports developer choice of language model, including Claude Code, Cursor, and Visual Studio Code, orchestrating Lattice Radiant across simulation, synthesis, place and route, timing analysis, and bitstream generation. Unlike other recent AI-assisted electronic design automation launches from Cadence and Synopsys, Lattice opted to expose its design flow through open MCP rather than build a proprietary copilot.
This approach allows developers to retain their existing agentic IDE and preferred model, with skills derived from Lattice documentation, datasheets, and internal expertise guiding the large language model’s operations, the firm reports. Prompt’s monetization strategy relies on increased silicon sales, as the tool itself is a free download, and each hour saved in design time lowers the barrier to adopting Lattice components.
Futurum Research notes this logic mirrors strategies seen in other recent EDA launches, making Lattice the first FPGA vendor to package its offering for the MCP ecosystem. The open MCP framework extends beyond simply accelerating design; it facilitates a broader integration with existing workflows. Lattice Prompt works with developer-selected large language models, enabling a flexible and customizable design experience, the company states. This contrasts with closed-system approaches that lock users into specific tools and environments.
The tool’s ability to use existing agentic IDEs minimizes the learning curve for developers already familiar with those platforms, further accelerating adoption and maximizing productivity gains. Lattice reports that the tool is currently available for download and has already shipped samples to customers in the compute and communications sectors.
The company’s strategy focuses on delivering a solution that not only meets emerging standards but also provides a competitive advantage in a market increasingly focused on post-quantum security, positioning Lattice to capitalize on a potential shift in procurement priorities as organizations prioritize security in their system designs.
Mach-N2’s Performance Scales for Dense Compute and High-Speed I/O
This quick configuration time, coupled with integrated non-volatile flash, distinguishes Mach-N2 from competitors relying on external flash for bitstream storage, mitigating security risks associated with data exposure during power cycles. The increased logic density of Mach-N2, scaling up to 220K system logic cells from the MachXO5’s 100K limit, directly addresses the growing demands of modern server boards. Current designs now incorporate four to eight GPUs, multiplying the need for power sequencing, telemetry, and management logic around each accelerator.
This scaling capability is further amplified by Lattice’s acquisition of AMI, adding a $200 million revenue base in platform firmware and manageability software. Lattice now provides both the authentication hardware via Mach-N2 and the platform firmware, creating a vertically integrated solution for system control and security.
Competitive Analysis: Mach-N2 Differentiates Through PQC Services
Lattice Semiconductor’s Mach-N2 family embeds 128 to 256 megabits of configuration flash directly into the silicon, a decision that defines its competitive positioning within the control FPGA market. Full CNSA 2.0 compliance separates Mach-N2 from competitors that align or plan, according to Futurum’s analysis. This adherence to emerging standards means Lattice meets potential procurement requirements before widespread post-quantum mandates take effect, a strategic advantage highlighted by Futurum’s analysis. Procurement teams should independently validate these claims against competitor specifications, as Lattice’s comparative boot and security table is compiled from publicly available user guides.
