The VL-COMm-33 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-33 has been engineered to meet the requirements of aviation, defense, industrial control, and medical applications while adhering to stringent regulatory standards. The VL-COMm-33 is manufactured to IPC-A-610 Class 2 standards. Equipped with an Intel Atom Bay Trail E38xx processor, it is designed to withstand extreme temperature, impact, and vibration.

Available in single, dual, and quad core versions, the COMm-33 provides extreme performance for its size. It does so at moderate power consumption (3.5 to 7.25W typical), in a very small package. The COMm-33 provides compatibility with a broad range of standard x86 application development tools for reduced development time.

The VL-COMm-33 utilizes advanced Intel technologies to maximize performance. Intel Virtualization Technology allows one VL-COMm-33 system to function as multiple "virtual" platforms. This enables computing activities to be isolated into separate partitions for increased application flexibility and reliability. Intel 64 architecture delivers 64-bit computing when combined with supporting software.

The integrated Intel Gen-7 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 COM Type 10 pin-out provides industry-standard system interfaces that include Gigabit Ethernet with network boot capability, a single USB 3.0/2.0 and six USB 2.0 ports, two serial ports, Intel High-Definition Audio (HDA), LPC, I2C, SPI, and SMBus to the carrier board. A dual SATA 3 Gb/s interface supports high-capacity storage. Optional on-board eMMC memory supports up to 8 GB of Flash.

Designed and tested for industrial temperature (-40º to +85ºC) operation, the rugged VL-COMm-33 also meets MIL-STD-202G specifications for shock and vibration. Soldered-down RAM provides additional ruggedization for use in extremely harsh environments.

The VL-COMm-33 is supported by a variety of thermal heat dissipation solutions, including a standard heat plate, heat sink, fan for heat sink, heat pipe, and other cooling / mounting solutions.

A wide input voltage range of 4.75 to 20 volts simplifies system power supply requirements. It is fully compatible with 12V automotive-type power systems.

The VL-COMm-33 is backed by a five-year warranty, 5+ year off-the-shelf availability guarantee, and expert US-based technical support. Product Life Extension options support availability through the year 2025.

Product customization is available, even in low quantities. Options include conformal coating, splash screen configuration, application-specific testing, BOM revision locks, special labeling, etc.

A compatible carrier card is required for operation of this COM module. Contact VersaLogic for custom designed carrier boards that meet your exact requirements. Please contact a VersaLogic Sales Engineer for more information.
