The NI cRIO-9045 is an 8-slot embedded controller combining real-time processing with FPGA coprocessing for distributed measurement and control systems. Built on an Intel Atom E3930 dual-core processor running at 1.3 GHz base and 1.8 GHz burst speed, it pairs 2 GB DRAM with a Kintex-7 70T FPGA for synchronized, deterministic I/O. The system runs NI Linux Real-Time (64-bit) and supports three C Series module programming modes: Real-Time via NI-DAQmx, Real-Time Scan via I/O Variables, and LabVIEW FPGA via the FPGA Module. Dual Gigabit Ethernet ports with Time Sensitive Networking enable precise timing across distributed systems. Additional connectivity includes USB 3.1 Type-C (dual role and DisplayPort Alt Mode), RS-232, and RS-485 serial interfaces. An SD card slot supports data logging without full-speed or high-speed card restrictions. Operating temperature range spans -20 °C to 55 °C. The controller fits a compact 12.94 x 3.47 x 4.77 inch footprint at 4 lbs, 15 oz.
