Rugged module runs Yocto Linux on up to 12-core Xeon-D

Dec 14, 2016 — by Eric Brown 1,706 views

Eurotech’s “CPU-161-18” is a headless COM Express Type 6 Compact module with a 12-core Xeon-D, up to 24GB DDR4, PCIe x16, and wide temperature operation.

Like Advantech’s SOM-5991, Eurotech’s CPU-161-18 is “server-class” COM Express Type 6 Compact module aimed at high-end embedded applications, and equipped with Intel’s 14nm “Broadwell” based Xeon D-1500 SoCs. The module can be purchased with 4x, 8x, or 12x core Xeon-D1500 models, ranging from the quad-core, 1.3GHz Xeon D-1529 with 20W TDP up to the 12-core, 1.5GHz Xeon-D1559 with 45W TDP. These TDPs are lower than those of many Xeon SoCs. There’s also a quad-core, 1.6GHz/2.2GHz Pentium D1517 with 25W TDP from the same Broadwell family.


The CPU-161-18 is designed for fanless, headless devices that require “in-the-field computation of large amounts of sensor data in vehicles, aircraft, vessels in remote locations,” says Eurotech. Specific applications are said to include autonomous driving, image processing, geological surveys, robotics, and deep learning.

While the Advantech SOM-5991 uses the 125 x 95mm COM Express Type 6 Basic variant, Eurotech’s entry adopts the smaller, 95 x 95mm Type 6 Compact form factor. Like the Advantech model, it offers extended temperature support, in this case -25 to 70°C.


The module has 8GB of soldered DDR4 RAM (2133-2400MT/s), as well as a socket that holds up to 16GB of DDR4 with ECC error correction, for a total of 24GB. There are also sockets for 16MB and 32MB of SPI flash.

Four SATA 3.0 interfaces are available, as well as a Gigabit Ethernet controller, 4x USB 3.0, and 7x USB 2.0. The CPU-161-18 features a single PCIe x16 plus 2x PCIe x4 interfaces, all of which can be reconfigured in various combinations.

Additional I/O includes 2x UART, 8-bit DIO, I2C, SMBus, and LPC. You also get a watchdog, RTC, temperature sensor, and Intel AES-NI security. Power inputs include 12V, 5V standby, and 3V for RTC.

The CPU-161-18 supports Yocto Linux, as well as Windows 10 IoT and VxWorks. Customization support is also provided, as well as a development kit.

“This new module closes a gap between the traditional embedded applications and servers, a new segment that requires a unique combination of computational performance and ruggedness”, stated Pierfrancesco Zuccato, Eurotech Senior Product Manager.

Further information

The CPU-161-18 will be available for order in Q1 2017. More information may be found on Eurotech’s CPU-161-18 product page.
