* EOL Notice: THE MX255D IS ON THE PHASE-OUT LIST. BCM is accepting last time buy (LTB) orders through June 14, 2017.  All last time buy orders may be scheduled to ship through June 14, 2018 with a non-cancellable and non-returnable (NCNR) PO. BCM may continue to accept orders for this product on a build to order basis with minimum order quantities. For a replacement product please consider our MX67QM; MX87QD, MX81H. For detail, please read the Official Release [PDF]

The MX255D is equipped with the 3rd generation Intel Atom 32nm D2550 desktop processor plus the Intel NM10 Express chipset. The D2550 carries dual core 1.86 GHz processing power compare to N2600 processor (1.66 GHz). The MX255D adopts D2550 desktop processor on a mini-itx small form factor which provides better system stability. The D2550 processor also integrates the Intel Graphics Media Accelerator 3600 and 4GB DDR3 memory capability supporting superior HD-rich content and dual independent display capability with DVI, 18/24-bit LVDS and VGA ports.

The upgraded memory feature provided by MX255D with its two So-DIMM sockets onboard support DDR3 memory modules up to 4GB offer a significant performance boost enabling greater system scalability. A key benchmark in changing to the D2550 processor was the ability of the MX255D to operate  fanless.  The  mini-itx motherboard still uses the same onboard 12V DC power interface.

The rich combination of the above features makes the MX255D a superior product in the value-performance category offering greater benefits for embedded computing applications such as  the retail Point of Sale, Kiosk, medical, digital signage and gaming industries.
