The VL-COMm-26 is an extremely small and rugged Computer on Module (COM) based on the industry-standard COM Express mini form factor. Roughly the size of a credit card, the VL-COMm-26 has been engineered to meet the military and medical industries requirements for smaller, lighter, and lower power embedded systems while adhering to stringent regulatory standards. The VL-COMm-26 is manufactured to IPC-A-610 Class 2 standards. For extremely-high-reliability applications, IPC-A-610 Class 3 (modified) versions are available. This embedded computer module, equipped with an Intel Atom E6x0T processor, is designed to withstand extreme temperature, impact, and vibration.


Driven by an Intel Atom E6x0T processor, the VL-COMm-26 provides significant performance and lower power consumption (7W8W typical) in a very compact package. The VL-COMm-26 provides compatibility with a broad range of standard x86 application development tools for reduced development time.

The VL-COMm-26 utilizes advanced Intel technologies to maximize performance. Intel Hyper-Threading Technology (Intel HT Technology) provides two processing threads per physical core which allows applications to work in parallel and complete tasks sooner. Intel Virtualization Technology allows one VL-COMm-26 system to function as multiple virtual platforms. This enables computing activities to be isolated into separate partitions for increased application flexibility and reliability. Enhanced Intel SpeedStep Technology enables high performance while meeting the power-conservation needs of embedded systems by switching voltage and frequency levels in response to processor load.

The integrated Intel GMA600 graphics core provides hardware-accelerated MPEG-4/H.264 and MPEG-2 video encoding and decoding. A standard LVDS output supports flat panel displays. An SDVO output supports a variety of signaling interfaces including VGA and DVI.

The standard Type 10 pin-out provides industry-standard system interfaces including Gigabit Ethernet with network boot capability, seven USB ports, three x1 PCIe lanes, two serial interfaces, Intel High-Definition Audio (HDA), LPC, and SMBus to the carrier board. An auxiliary board-to-board connector provides two additional serial interfaces and a CAN interface. Dual SATA 3 Gb/s interfaces support high-capacity storage. A microSD socket provides flexible solid-state drive (SSD) options.

For enhanced security, the VL-COMm-26 supports Execute Disable Bit functionality. This hardware-based security feature reduces exposure to viruses and malicious-code attacks by preventing harmful software from executing and propagating on the network. An optional on-board Trusted Platform Module (TPM) is available for applications that require additional hardware-level security functions.

Designed and tested for industrial temperature (-40 to +85C) operation, the rugged VL-COMm-26 also meets MIL-STD-202G specifications for shock and vibration. Soldered-on RAM provides additional ruggedization for use in extremely harsh environments. Heatsink or heat plate versions provide fanless heat dissipation. Thermal monitoring technologies protect the system from thermal failure by reducing power consumption when required to remain within normal thermal operating limits.

A wide input voltage range of 8 to 17 volts (12V typ.) simplifies system power supply requirements. It is fully compatible with 12V automotive-type power systems.

The VL-COMm-26 is compatible with a variety of popular x86 operating systems including Windows, Windows Embedded, Linux, and VxWorks.

Product customization is available, even in low quantities. Options include a Trusted Platform Module, conformal coating, BGA underfill, IPC Class 3 (modified) construction, BIOS/splash screen configuration, application-specific testing, BOM revision locks, special labeling, etc.
