Tiny computer-on-module runs Linux on Atom N2800

Aug 7, 2013 — by Eric Brown — 2310 views

Advantech announced a tiny module based on the COM Express Mini form-factor and built around an Intel 1.86GHz dual-core Atom N2800 processor. The business-card sized SOM-7565 A2 supports up to 4GB of RAM and 8GB of flash, offers a wide range of I/O, expands with three PCIe lanes, consumes 8 to 9.5 Watts, and supports -40 to 85°C operation with its optional heatsink.

Like Advantech’s earlier Atom N2600-based SOM-7565 module, the SOM-7565 A2 follows the 84 x 55mm COMe Mini form-factor, or more specifically the PICMG COM-Express R2.1 Mini Module, Type 10. The device is well-suited for portable applications in medical, factory, or general detector devices, says Advantech. With the addition of an optional heatsink, the fanless design supports industrial temperature ranges suitable for ruggedized solutions in severe environments, says the company.

The A2 model moves up from the 1.6GHz Atom N2600 to the similarly dual-core Cedarview architecture N2800, which is clocked to 1.86GHz. The integrated Intel gfx graphics supports DX9 and OGL 3.0 standards. The N2800 is also available as a processor upgrade for the SOM-7565.

Compared to Advantech’s earlier Pineview-generation Atom COMs like the SOM-7564 E680 and SOM-7562 N455, the N2800-based SOM-7565 A2 offers a more than 200 percent increase in performance and a 300 percent improvement in 3D graphics processing, claims Advantech. The Atom N2800, here accompanied by the NM10 chipset, was also used in Advantech’s MI/O-Ultra Pico-ITX board.

The SOM-7565 A2 appears to be identical to the SOM-7565 except for the processor, as well as a doubling of the RAM (to 4GB DDR3) and flash (8GB solid state drive). Both RAM and flash are said to be soldered for greater vibration resistance.

The module supports simultaneous displays between the 18-bit LVDS connection and the shared HDMI/DVI/DisplayPort interface, which supports up to up to 1600 x 1200 resolution. Three PCI Express (PCIe) x1 expansion lanes are provided, along with legacy buses, and a gigabit Ethernet controller. Additional interfaces are said to include a SATA 3 port, eight USB 2.0 ports, HD audio, and GPIO.
