Part 2.2: Automotive and Industrial Control — Reliability Meets Real-Time Performance
Automotive and industrial markets are among the most demanding for FPGA deployments. These environments require deterministic real-time performance, safety certification, and long lifecycle support. For engineers, FPGAs provide flexible hardware for ADAS, robotics, and industrial automation. For managers, automotive and industrial projects require parts with functional safety compliance, extended lifetimes, and guaranteed supply stability.
1. Automotive-Grade FPGA Selection
- Engineer’s View: Automotive FPGAs must meet ISO 26262 functional safety standards and AEC-Q100 qualification. They are used in ADAS sensor fusion, in-vehicle networking, and infotainment systems. Wide temperature tolerance and low failure rates are mandatory.
• Manager’s View: Automotive-grade parts are more expensive than consumer-grade equivalents, but their long lifecycle (15+ years) aligns with vehicle development cycles. ASP ranges from $30 for simple devices to $500+ for advanced SoC FPGAs.
2. Industrial Real-Time Control
- Engineer’s View: Industrial systems like robotics, PLCs, and motor control demand deterministic timing and reliability under harsh conditions. Mid-range FPGAs are widely used to integrate industrial communication protocols such as EtherCAT, Profinet, and Modbus.
• Manager’s View: Industrial FPGAs often guarantee availability for 10–15 years, essential for factories and automation equipment. ASP typically ranges from $20–$100. Energy efficiency and wide-temperature operation lower total system cost.
• Examples: Xilinx Artix-7, Intel Cyclone 10, Lattice ECP5.
