NIU1A Nano Interface Unit

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 data acquisition, distribution and communication interfaces to mission computers in military and aerospace embedded applications – without expensive chassis and backplane redesign.

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 A/D, D/A, 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® Linux, VxWorks and Xilinx® PetaLinux. SSKs are supplied with source code and board-specific library I/O APIs to facilitate system integration.
