Functional Description
The Parvus DuraCOR 310 is an ultra-small form factor (SFF) tactical mission computer based on a low-
power; four-core NXP i.MX6 Quad ARM processor equipped with a rugged Flash disk and PCIe-Mini
Card I/O expansion slots. At less than 40 in3 in volume, 1.5 lbs. in weight, and 10W power, this miniature
multi-core rugged Commercial-Off-the-Shelf (COTS) processor is an ideal solution for size, weight, power
and cost (SWaP-C) sensitive mobile, airborne, ground, manned and unmanned vehicle and sensor
applications. Optimized for high performance energy efficient processing, the unit boasts a quad-core
CPU with HD-class video acceleration, including OpenGL, OpenCL, and OpenVG accelerators
The ultra-reliable and modular design of the DuraCOR 310 features high mechanical robustness and I/O
flexibility to meet the needs of civil and military and aerospace platforms. The unit features an industrial-
grade ARM-based Computer-on-Module (COM) tightly integrated with a Flash SSD and system carrier
board, which provides a full complement of standard vetronics I/O interfaces (including CANbus, USB,
Ethernet, Serial, DIO, Video, and Audio), as well as up to two slots for optional add-on Mini- PCIe I/O
modules. In addition to internal mSATA and microSD card slots, the system offers an optional removable
2.5” SATA SSD storage option for high capacity storage and information assurance requirements. Like
other DuraCOR models, the 310 leverages both an ecosystem of rugged COTS Mini-PCIe modules
(including MIL-STD-1553 and ARINC429 avionics databus interfaces) and Curtiss-Wright’s responsive,
cost-competitive application engineering services to deliver Modified COTS (MCOTS) variants quickly and
without a traditional NRE fee.
The unique combination of small size, low-power multi-core processing, and flexible I/O of the DuraCOR
310 delivers new capabilities for Command, Control, Communications, Computers, Intelligence,
Surveillance and Reconnaissance (C4ISR) applications. This compact system supports a wide operating
temperature range of -40 to +71°C (-40 to +160ºF) without fans or active cooling requirements. It thrives
in extreme shock/vibration conditions, high altitude, and humidity, making it well suited for mobile, tactical,
aerospace, and ground vehicle applications. Reliably designed for use on-board aircraft and vehicle
platforms, the unit will undergo comprehensive qualification testing to MIL-STD-810G, MIL-STD-461F,
MIL-STD-1275D, MIL-STD-704F and RTCA/DO-160G test conditions for environmental, power and EMI
(thermal, shock, vibration, dust, water, humidity, altitude, power spikes/surges, conducted/radiated
emissions and susceptibility).
Housed in a rugged sealed IP67-rated (dust and water proof) aluminum chassis with MIL-performance
circular connectors, the DuraCOR 310 features advanced EMI filtering and power conditioning to protect
against input vehicle/aircraft voltage surges, spikes and transients. In addition, optional 50ms power hold-
up capabilities are supported for MIL-STD- 704F aircraft power switch-over requirements.
Features
 Miniature SWaP-optimized quad-core NXP i.MX6 ARM processor system:
 Size: ~40 in³ volume
 Weight: < 1.5 lbs. (< 0.68 kgs)
 Power: < 10W (estimated)
 Rugged IP67 chassis with micro-mini MIL-performance circular connectors
 Modular I/O architecture: up to two slots for PCIe Mini-Cards (for add-on I/O)
 Rugged Flash storage (mSATA / microSD card / removable 2.5” SATA SSD)

DuraCOR 310 Chapter 1 Introduction
Page 10 of 51 MNL-0666-01 Rev A3 ECO-5479 Effective: 26 Apr 18
 28 VDC MIL-1275/704/DO-160 power supply for aircraft and ground vehicles; optional 50 ms
power hold-up
 Qual testing pending for extreme MIL-STD-810G/DO-160 thermal, shock, vibration, altitude,
humidity; also MIL-STD-461F/DO-160G EMI/EMC
 Designed and manufactured using AS9100 Aerospace Grade/ISO 90001:2000 certified Quality
Program.
 CE Marking
Configurations
Due to the modularity of the DuraCOR 310 (mSATA/microSD/Removable SSD, and pre-integrated Mini-
PCIe cards), numerous configuration variants are possible. Please consult with your sales representative
and application engineer to assess your technical requirements and recommended system configuration.
