MEN Mikro DC2 - Intel® Atom™ SBC for Intelligent Displays

Intel® Atom™ processor, -40 to +70/85°C Operating

Introduction

The SC21 is a rugged, fanless and maintenance-free single-board computer for intelligent display devices, e.g., for infotainment purposes in trains, public buses or airplanes. Its small size makes it suitable for display devices with TFT LCD panels as small as 10.4".

The SC21 is controlled by the Intel® Atom™ XL Z520PT running at 1.33 GHz and comes with 1 GB of DDR2 SDRAM and a MicroSD card slot. The standard interfaces comprise 2 Fast Ethernet (via RJ45 connectors) and 2 USB ports as well as four binary inputs (via the 10-pin power supply connector). The two Ethernet interfaces have switch functionality to provide Ethernet connection to subsequent intelligent displays. A temperature sensor is provided to monitor and control the display. With the exception of the LVDS signals and the display backlight brightness control, all I/O signals are concentrated on a customizable connector PCB, including a USB-driven connector for a touch interface.

The SC21 is equipped with an internal 9 to 36V (12VDC nom. or 24VDC nom.) wide-range power supply and able to operate in a -40 to +70°C environment (+85°C for 10 minutes) with sufficient cooling. It complies with the class Tx railway standard, an optionally available external PSU suited for railway applications can also provide EN 50155 conformity. All electronic components are soldered to withstand shock and vibration and prepared for conformal coating.

Options include other types of the Intel® Atom™ XL processor, a brightness sensor to control the display, a serial interface that can be added via an SA-Adapter, HD audio via a D-Sub connector and an additional LVDS connection for a secondary display, with the two displays then showing individual or identical content as required by the application. A PCI Express® Mini Card slot (with a SIM card slot) in combination with an external antenna can be used to incorporate wireless functions like Wi-Fi, WIMAX, GSM/GPRS, UMTS etc.
