Concurrent SBC Complies With OpenVPX VITA 65

Concurrent Technologies has introduced an ultra-low-power 3U VPX-REDI single-board computer (SBC), the TR A40/30xRC, designed to comply with the OpenVPX VITA 65 standard. The TR A40/30xRC utilises the 1.6GHz Intel Atom processor Z530 and the integrated Intel System Controller Hub US15W, both from the Intel embedded roadmap. The board supports up to 2GB DDR2-533 soldered SDRAM and a variety of I/O interfaces, including a CANbus interface, yet maintains a typical power requirement of less than 10W.

The RC-Series TR A40/30xRC is a VPXREDI Type 1 Two Level Maintenance conduction-cooled board with support for Built In Test (BIT). The TR A40/30xRC SBC provides a flexible PCI Express (PCIe) OpenVPX backplane fabric interface that can be configured for several OpenVPX slot profiles from 8x1 PCIe ports through to 2x4 PCIe ports. This fabric flexibility makes the board suited for systems with direct wiring between slots on the backplane and for systems linked by a fabric switch card.

An air-cooled pin-compatible VPX version is also available for non-rugged applications and bench development. The TR A40/30xRC 3U VPXREDI Intel Atom processor SBC is suited to low-power rugged applications, particularly within the defence market. The 1.6 GHz Intel Atom processor Z530 is manufactured using 45nm technology and provides 512kB L2 cache. It supports Intel Hyper-Threading Technology and Intel Virtualisation Technology. The Intel System Controller Hub US15W is a memory controller (interfacing to 1 or 2GB DDR2-533 soldered SDRAM), along with an I/O controller hub and graphics controller combined in a single-chip package.

Intel specifies the combined Thermal Design Power of the processor and chipset as less than 5W. This VPX SBC also supports dual-Gigabit Ethernet (or dual 1000 Base-BX) ports, a high-speed CANbus controller, two USB 2.0 ports, two RS-232/RS-422/RS-485 ports, two Serial ATA300 interfaces , DVI-D graphics and Intel High Definition stereo audio. An XMC module can be fitted to the onboard XMC site within a single slot. The XMC interface supports a x4 PCI Express link along with Pn6 XMC rear I/O to the P2 connector mapped out as P2w7-X8d+X12d.

For embedded applications, the board supports 4GB of onboard NAND Flash via an EIDE interface. Other features provided are a PC real-time clock, watchdog timer, long-duration timer and four GPIO signals. The VITA 46.0 compliant TR A40/30x is an air-cooled SBC designed for non-rugged environments, operating over a temperature range of 0 to 55C. The pin-compatible TR A40/30xRC is designed as a conduction-cooled SBC (to VITA 48.2) for rugged environments (to VITA 47 Class V3 vibration, Class OS2 shock) and operating over temperatures of -40 to 85C (to VITA 47 Class CC4) and at altitudes from -1,000 to 50,000ft (-305 to 15,240m).

For increased physical protection the TR A40/30xRC is also a 3U VPXREDI Type 1 Two Level Maintenance SBC fitting into a 0.85-inch slot width (to VITA 48.2). Operational self-diagnostics are supported in the form of Built-In Test (BIT) including Power-on BIT (PBIT), Initiated BIT (IBIT) and Continuous BIT (CBIT). The VPX data-plane interface is a configurable PCI Express (PCIe) backplane fabric interface. The backplane fabric interface can be configured as 8x1 PCIe ports, 2x4 PCIe ports, or 1x4 and 4x1 PCIe ports. All fabric configurations are compatible with OpenVPX slot profiles.

By using one of the latest PCI Express switches the board supports PCI Express Gen 1 and Gen 2 as well as providing a four-channel DMA engine for fast data-block moves. Multiple TR A40/30xRC SBCs can be used on the same backplane (providing multi-processing) as the board also supports an option to set up link 1 in the fabric as a non-transparent bridge. The VPX control plane interface on the TR A40/30xRC can be configured as 2 x 10/100/1000Mbps Ethernet ports or 2 x 1000Mbps IEEE802.3z SERDES (1000 Base-BX) ports. System management is provided to monitor the system fan, board voltages and CPU temperature.

This capability is provided via SM0-1 and SM2-3 on the P0 connector, using a Baseboard Management Controller and 8kB of non-volatile memory. For ease of integration, the TR A40/30x VPX SBC and the TR A40/30xRC VPXREDI SBC support operating systems including Linux, Windows XP, Windows XP Embedded, QNX and VxWorks. The OpenVPX standard defines the VPX Systems Specification, an architecture that manages and constrains module and backplane designs. The VPX Systems Specification includes the definition of pin outs and sets interoperability points within VPX, while maintaining full compliance with the existing VPX specification.
