The Bengal is a low-power / high-performance single board computer (SBC) with a full complement of on-board I/O. Driven by the low power Intel® 22nm Silvermont microarchitecture, the Bengal provides up to 1.9 GHz of performance with quad, dual, and single-core processor options. Based on the industry-standard PC/104 format (4.23 x 3.77 inches), this SBC is an excellent solution for size, weight and power (SWaP) constrained applications.

Bengal is built on the new “PCIe/104 OneBank” format. Compatible with the PCI/104 Express format, it includes a legacy PCI connector, and a single bank high-speed PCIe connector. This provides flexible system expansion, while leaving more on-board space available for product features. The single bank connector is mechanically and electrically compatible with the existing PCI/104-Express Type 1 and Type 2 modules.

As with all VersaLogic products, the Bengal is designed to support OEM applications where high reliability and long-term availability are required. From application design-in support, to its 5+ year production life guarantee, the Bengal provides a durable embedded computer solution with an excellent cost of ownership.

VersaLogic products are designed for use by OEMs working in a variety of market applications: Aerospace, Defense, Energy, Industrial, Security, Medical, Military, Robotics, and Transportation. Anywhere that the need for superb quality and high-performance embedded computing exists, applications include: automation, avionics, gateway, in-vehicle, monitoring, simulation, and vision.

VersaLogic delivers extremely reliable standard and customized embedded computers backed with unsurpassed service and the highest availability in the market. VersaLogic exists to exceed customers' product, service, support and delivery needs - whenever and wherever the need arises.
