Aitech Intros Low Power SBC Reducing Avionics Costs
Single-board computer.
Chatsworth, CA — Aitech Defense Systems, Inc. now offers the RTCA-compliant C920, a rugged 3U CompactPCI PowerPC-based SBC (single board computer) with very low power dissipation of typically less than 5W. The new SBC helps significantly reduce engineering resources typically diverted to RTCA design requirements, saving on overall system and software development costs.

As the latest evolution in the company's C92x family of rugged, avionics-centric computing boards, the C920 is suitable for high reliability DO-178 and DO-254-based airborne platforms. The new SBC is safety-certifiable to the highest DAL A levels of both DO-178 (software) and DO-254 (hardware), making it an excellent choice for safety and mission-critical applications.

With its existing certifications, the new, super-low power SBC is suitable for flight and mission control computers in avionics platform subsystems destined for FAA-controlled airspace. In addition to reduced design costs, the C920 saves on DO-254 certification costs by minimizing the use of on-board FPGAs. Able to provide increased processing power without the added overhead of additional heat generation, the C920 incorporates a highly integrated PowerQUICC II 8349E processor that is hardware-preconfigured to 400MHz, ensuring the right mix of high processor horsepower and low power dissipation. The processor also has an on-chip 32kB instruction and a 32kB data L1 cache that support a powerful e300 core.

The C920's large on-board memory consists of up to 256MB fast DDR2 266 SDRAM with ECC protection for exceptional data integrity, 128MB of boot Flash, 256MB of user Flash and 512kB NVRAM implemented with a fast MRAM (magneto-resistive RAM) for fast read/write storage of critical mission and key board parameters as well as user data storage. MRAM's unlimited write/erase capacity prevents it from wearing out — a problem associated with other Flash or SSD technologies — increasing the board's long-term reliability. The C920's compact 3U form factor accommodates a wide range of integrated I/O including two 10/100 BaseT Ethernet ports and two RS-232/-422/-485 serial ports. To control real-world systems, the rugged SBC also provides 21 single-ended general purpose TTL discrete I/O lines, where each line is independently user-programmable as either an input or output and able to generate a processor interrupt on a change of state.
