PICMG 1.0 board features choice of Atoms

Oct 14, 2011 — by Jonathan Angel — from the LinuxDevices Archive — 14 views

Advantech announced a full-size PICMG 1.0 single board computer (SBC) that's available with Intel Atom N455 or D525 processors. The PCA-6012 supports ISA and PCI expansion, includes VGA and optional LVDS video, has dual gigabit Ethernet ports, and offers up to nine USB 2.0 ports.

At 13.3 x 4.8 inches, Advantech's PCA-6012 is rather large for an Atom-powered SBC, since it uses the full-length PICMG (PCI Industrial Computer Manufacturers Group) 1.0 format. (PICMG 1.0 presents ISA and PCI interfaces to the backplane, whereas PICMG 1.3 offers PCI Express and/or PCI/PCI-X interfaces.)


Advantech's PCA-6012

Where most PICMG boards we've covered recently have emphasized performance by using Intel Core processors, the PCA-6012 goes the power-saving route. It's offered with Intel's Atom N455 (1.66GHz, single core, 5.5-Watt TDP) or D525 (1.88GHz, dual core, 13-Watt TDP).

Both these processors are coupled here with Intel's ICH8M I/O controller, but the D525 can address more memory: Therefore, the PCA-6012's two DIMM slots accept up to 2GB of RAM in the board's N455 version, and 4GB of RAM in the D525 version. However, only the N455 version can run fanlessly, Advantech notes.

The N455 and D525 variants of the PCA-6012 also differ in what externally accessible ports they offer. As shown above left, the N455 version has a PS/2 port, a DB9 serial port, a single gigabit Ethernet port, and a VGA port. The D525 version (above right) has a PS/2 port, two gigabit Ethernet ports, and a USB 2.0 port.

According to Advantech, the D525 version also comes with a CompactFlash slot that's optional on its N455 sibling. Both, however, include three SATA ports, along with headers for eight USB 2.0 ports and two RS232 ports.

Advantech says the PCA-6012 SBCs also include headers for a parallel port, a floppy disk connector, and 8-bit GPIO. An optional module can add four RS-485 ports with auto flow control, and LVDS video output is also available, the company adds.
