North Atlantic Industries Announces Latest Nano Interface Unit NIU3A SWaP Optimized Processing, Multifunction I/O & Communications System

BOHEMIA, NY – April 2021 -- North Atlantic Industries, Inc. (NAI), a leading supplier of embedded computing solutions and power supplies, introduces the NIU3A rugged nano interface unit. The NIU3A is a SWaP-optimized, self-contained processing and multifunction I/O system preconfigured with 24-CH programmable Discrete I/O, 8-CH ARINC 429/575, 4-CH CAN bus (supports CAN 2.0A/B, ARINC 825 or CAN FD protocols) and 2-CH redundant MIL-STD-1553 communications functions. In addition, the Configurable Open Systems Architecture™ (COSA®) enables the NIU3A to be configured with up to three smart function modules from a selection of over 70 Analog and Digital I/O, Position, Timing, Measurement/Simulation and Communications smart functions.

The NIU3A is low power, offers a small footprint of 7.2” x 5.65” x 3.25” (est.) and weighs less than 6 lbs. The NIU3A boasts Dual or Quad ARM Cortex®-A53 processors for customer software applications. It is configured with two 10/100/1000BASE-T (GbE) Ethernet ports and an RS-232 port for maintenance / diagnostic or configuration interface. Xilinx® PetaLinux, Wind River VxWorks 7.x or VxWorks HVP and DDC-I Deos RTOS support continues NAI’s commitment of a safety critical DO-178C and DO-254 certification support path.

“The configurability, adaptability, and flexibility of the NIU3A with three COSA module slots plus integrated I/O and communications, make it the ideal DO-178C and DO-254 DAL A certifiable system or subsystem solution for the digital backbone on Future Vertical Lift FARA and FLRAA programs,” said Lino Massafra, VP of Sales and Marketing. “With optional support for FIPS-140-3 Level 3 cybersecurity and deterministic Time-Triggered Ethernet (TTE) or Time Sensitive Network (TSN).”

NAI is a leading independent supplier of embedded computing, Input/Output, communications, measurement, simulation, power and systems products for commercial, industrial and military applications built on a Configurable Open Systems Architecture™ (COSA®). COSA offers the greatest modularity, flexibility, adaptability and configurability in the industry that accelerates our customers’ time-to-mission. COSA supports a Modular Open Systems Approach (MOSA) that delivers the best of both worlds: custom solutions from COTS components with No NRE. For over 50 years, companies like Lockheed Martin, Boeing, Northrop Grumman and Raytheon have leveraged NAI’s capabilities to meet the demanding requirements of a wide range of processing, I/O and communication-centric applications, and do so with uncompromising quality, efficiency and responsiveness.
