NIU3A

SWaP Optimized Processing and Multifunction I/O & Communications System

Rugged Embedded Nano Interface Unit with Xilinx® UltraScale+ Dual or Quad Core ARM Cortex®A53 Processors with 3 Expansion COSA® Module Slots

The NIU3A is a small, rugged, low-power, self-contained processing and multifunction I/O system preconfigured with 24-CH programmable Discrete I/O, 8-CH ARINC 429/575, 4-CH CANBus and 2-CH MIL-STD-1553 functions. The NIU3A can also be configured with up to three smart Configurable Open Systems Architecture™ (COSA®) function modules. The NIU3A boasts Dual or Quad Core ARM Cortex®-A53 processors for customer software applications and I/O and communications management. The NIU3A is configured with two 10/100/1000BASE-T (GbE) Ethernet ports and an RS-232 port for maintenance / diagnostic or configuration interface. Ideally suited for rugged Mil-Aero applications, the NIU3A delivers off-the-shelf solutions that accelerate deployment of SWaP-optimized systems in air, land and sea applications.

The NIU3A rugged multifunction I/O and communications platform provides scalable system level solutions enabling networks including on-board vehicle, marine and aircraft platforms, to field and expand digital network architectures for network-centric operations. A dual capability module slot allows for PCIe modules that offer support for single channel, Tri-Redundant TTE / AFDX (ARINC 664 part 7) / Best Effort Ethernet (2 x 10/100/1000BASE-T) or two nodes with 3 ports/node FireWire (IEEE 1394) communications interface.

Accelerate Your Time-to-Mission™ With COSA®

NAI’s Configurable Open Systems Architecture™ (COSA®) offers a choice of over 70 smart I/O, communication, and Ethernet switch functions, providing the highest packaging density and greatest flexibility of any multifunction I/O board in the industry. Preexisting, fully-tested functions can be combined quickly and easily in an unlimited number of ways. Each I/O function has dedicated processing, unburdening the system Single Board Computer (SBC) from unnecessary data management overhead.
