System-On-Module Standard

MEN Micro Inc. (Ambler, PA) has announced the ESMexpress® System-On-Module Standard, a new computing standard in development to be the ANSIVITA 59 (RSE Rugged System- On-Module Express) standard. In conjunction with the new standard, they have also an - nounced the XM1 featuring the first-generation Intel® Atom® processor (Z530 at 1.6 GHz or Z510 at 1.1 GHz) based on 45-nm technology coupled with 1 GB of soldered DDR2 SDRAM for significantly lower power dissipation, reduction in design costs, and space-saving design flexibility. ESMexpress combines this model with advanced cooling technologies, and the latest serial buses and rugged components to ensure safe, reliable operation in harsh environments found in areas as diverse as the railway, avionics, industrial automation, medical engineering and mobile industries.

ESMexpress provides for extreme resistance against shock and vibration. Eight screws secure the module to the carrier board. In addition, a mechanically robust connector specified for MIL and railway applications supports differential signals with up to 8 GHz, features a stacking height of 5 mm with a minimum tolerance of +/-0.3 mm, is equipped with fixed contacts for power supply, and is specified for an operating temperature range of -55°C to +125°C. The Intel-based XM1 offers a screened temperature range of -40°C to +85°C. The electrical signals are distributed on two 120-pin connectors and are only defined for modern serial buses. For PCI Express there are four single lane ports (4 ×1) and one port that can be configured as 1 ×16, 1 ×8, 2 ×4 or 2 ×1. Other ports include three 1-Gigabit Ethernet (also as 10- Gigabit), eight USB, three SATA, SDVO, LVDS, HD Audio, several utility signals, and a single 12V power supply.
