Customer-configurable Embedded COTS System – NIU1A Nano Interface Unit

North Atlantic Industries

NAI’s NIU1A is a nano-sized, Intelligent I/O™ Communications System with embedded computing capability. It consists of an integrated power supply, one function module slot, and an optional SoC dual ARM Cortex-A9 processor. The compact unit has unprecedented I/O capability and connects to existing platform Ethernet networks, making data available to any system on the network. It easily adds sensor , distribution and communication interfaces to mission computers without expensive chassis and backplane redesign, for use in military and aerospace embedded applications.

Versatile Architecture

Built on NAI’s Custom-On-Standard Architecture™ (COSA™), the highly configurable NIU1A offers a choice of more than 40 intelligent I/O and communications functions. These pre-existing, fully-tested functions can be selected quickly and easily to meet system requirements. Available functions include , , TTL, RTD, discrete I/O, differential transceiver, synchro/resolver, LVDT/RVDT measurement, simulation and excitation, strain gage, quad channel redundant BC/RT/MT MIL-STD-1553, high-speed sync/async RS232/422/423/485, ARINC 429/575 and CANBus.

Equipped with three mounting options, the system is designed to operate under extreme temperature, shock, vibration and EMI environments. Total power consumption is minimal (NIU1: 6-10W, NIU1A: 8-12W), depending upon which I/O module is selected.

NAI’s NIU1A delivers smaller size, lower power, higher bandwidth, shared memory and lower latency – in a small package.

Board Support Package (BSP) and Software Support (SSK)
In addition, the NIU1A offers comprehensive processor software programming support for Wind River® , VxWorks and Xilinx® PetaLinux. SSKs are supplied with source code and board-specific library I/O APIs to facilitate system integration.
