CoM for harsh environments

Paul Boughton
MEN's new computer-on-module (COM) with an Intel Atom XL processor makes it possible for the user to operate the board in the extended temperature range of -40°C to 85°C and provides a higher memory capacity. MEN's COM module XM1L can be equipped with a number of different Intel Atom XL processors – dependent on the needs of the application.
The XM1L is MEN's latest ESMexpress Computer-On-Module. It is based on different Intel Atom processors – all from the Intel Atom XL family – which offer a maximum power dissipation of 7 Watts at a speed of up to 1.6 GHz. Unlike its predecessor, the Intel Atom XL is tested and qualified for the extended temperature range.
The COM module is used on a customer-specific carrier board on which the I/O interfaces can be accessed. Dependent on the processor version these include a combination of PCI Express links, LVDS, SDVO, audio, SATA, Ethernet with Wake-on-LAN function and USB. Additional COM interfaces can be made available on the carrier board via USB to COM conversion.
The DDR2 SDRAM with a size of up to 2 GB is soldered against shock and vibration. The memory capacity can be extended by a USB Flash on the carrier board.
A Board Management Controller for monitoring all board functions completes the functionality of the XM1L. For testing of the XM1L and for developing the application, the universal carrier board XC1 in ATX format can be used. The XM1L can also be plugged onto COM Express carrier boards (basic form factor type 2) via the adapter board AE12.
The XM1L is qualified for an operating temperature of 40°C to 85°C with conduction or convection cooling. Like all ESMexpress modules it is installed in a closed housing which also guarantees 100% EMC protection. The dimensions of all ESMexpress modules are 95x125mm.
