The CPU-71-18 is a high performance Single Board Computer (SBC) based on the VMEbus 6U form factor. It is based on Intel Atom E3800 series (code name Bay Trail), which offers extremely low power consumption in its system on chip (SoC) format, without a companion chip. The SoC offers a broad variety of I/O on a single chip, including USB, SATA, two graphics ports, SD interface and UART; as well as a DRAM controller.
The CPU-71-18 is designed to perform reliably in systems that operate in harsh environments, and supports an extended temperature range (-40 to +85°C).
The CPU-71-18 further reduces the power consumption of the chipset with microcontroller-based technology, making it the ideal platform for fanless, power constrained systems. The CPU-71-18 also supports two 10/100/1000Mbps Ethernet ports. Conduction-cooled versions are available.
