Guidance Systems

Meet mission requirements with low power and high reliability advantages of Lattice FPGAs

For over 25 years, , Lattice has enabled leading-edge guidance systems with a wide range of high reliability, SWAP-C optimized products that meet today’s security, longevity, and extreme environment challenges. Engineers at leading defense contractors rely on our deep system-level knowledge, collaborative spirit, local support, and design resources to meet the most stringent design requirements.

Lattice COTS FPGAs provide the flexibility to adapt to the requirements of next generation precision guided systems with low power actuator control, sensor fusion, and signal processing solutions. The latest Lattice Nexus platform features industry leading low power and high reliability to meet the challenging requirements of next generation guidance platforms.

Key Lattice FPGA Features & Benefits

  • Superior low power consumption and thermal performance compared to other FPGAs, enabling longer missions, and simplifying thermal management
  • Industry leading small form factor FPGAs, optimized for highest I/O density, connect to more sensors, creating a high-fidelity situational awareness
  • Lowest soft error rate (SER) in its class and highest latch-up immunity to maximize integrity of ground-based and airborne systems
  • Enables low latency, deterministic, instant-on start-up with initial I/O configuration in less than 3 ms and full device configuration in as little as 8 ms
