North Atlantic Industries announces the release of its NIU1U Nano Interface Unit – a next-generation evolution of NAI’s field-proven Nano Interface Unit family. Building on a successful, widely deployed product line, the NIU1U preserves the compact, rugged, SWaP-optimized design philosophy customers already rely on while delivering a major step up in processing, memory, storage, networking, and operating system support. Built on NAI’s Configurable Open Systems Architecture™ (COSA®), the NIU1U combines embedded processing, networking, and configurable I/O capabilities in a rugged, self-contained system suitable for air, land, and sea platforms.
The most significant advance is at the processing core. Where the prior generation offered an optional 32-bit ARM® Cortex®-A9 processor, the NIU1U integrates a 64-bit Xilinx® Zynq® UltraScale+™ SoC with dual-core or quad-core ARM® Cortex®-A53 processing as a standard, central capability – transforming the platform from a primarily Ethernet-attached I/O concentrator into a true edge-processing node that can host customer applications while simultaneously managing system I/O and communications. The next-generation design also adds 4 GB of LPDDR4 memory and 40 GB of onboard solid-state storage as standard – resources not part of the prior-generation base design – giving programs meaningful onboard compute and data-handling headroom in the same nano-class footprint.
The NIU1U retains the proven COSA flexibility of its predecessor — a single standard or PCIe-capable function module slot with more than 100 interchangeable smart I/O, communication, and networking functions — while opening a new dimension of capability through the Zynq UltraScale+™ SoC’s integrated programmable logic (FPGA fabric). That on-chip fabric provides headroom to implement embedded deterministic networking firmware and protocol acceleration directly within the main SoC architecture, enabling custom edge I/O, processing offload, and advanced network synchronization alongside the ARM processing cores. Supported deterministic networking implementations can include Time-Sensitive Networking (TSN, IEEE 802.1) and Time-Triggered Ethernet (TTE, SAE AS6802), including support for multiple Ethernet traffic classes such as Time-Triggered Ethernet (SAE AS6802), ARINC 664 Part 7 / Avionics Full-Duplex Switched Ethernet (AFDX®), and IEEE 802.3 best-effort Ethernet. As a result, the NIU1U can be configured both to aggregate and process sensor and I/O data at the edge and to operate as a node within deterministic, time-synchronized Ethernet architectures — making it well suited for network interfacing, data concentration, vehicle electronics, avionics, mission systems, and health monitoring applications.
“The NIU1U is a deliberate upgrade for programs already invested in our Nano Interface Unit platform – we moved from an optional single processor to an integrated, multi-core 64-bit SoC, added standard onboard memory and storage, and opened up programmable logic for embedded deterministic networking, all while staying true to the compact, rugged, SWaP-optimized design our customers depend on,” said Lino Massafra, Vice President of Sales and Marketing at North Atlantic Industries. “It gives them a clear, low-risk path to add edge processing and modern, time-synchronized networking to existing fielded systems without a costly redesign.”
Designed for deployment in demanding military and aerospace environments, the NIU1U supports Gigabit Ethernet connectivity, optional USB 2.0 and serial maintenance interfaces, an optional power supply hold-up for ride-through, and continuous background Built-In Test (BIT). Operating system support has been broadened well beyond the prior generation to include modern environments such as Wind River® VxWorks® 7, Xilinx PetaLinux® 2023.x, and DDC-I Deos. Its compact, rugged design makes it well suited for deployment as a Nodal Access Unit (NAU), Data Concentrator Unit (DCU), Remote Interface Unit (RIU), or Health & Usage Monitoring System (HUMS).
The NIU1U provides a rugged, configurable embedded computing solution that simplifies integration while enabling scalable system architectures. As the next generation of NAI’s COSA-based Nano Interface Unit portfolio, the platform extends the life of fielded I/O and communications architectures while delivering the processing, networking, and software headroom required by today’s mission-critical applications.
