The XM1L is a Computer-On-Module of the ESMexpress® family in accordance with a proposed ANSI standard currently under development (ANSI-VITA 59, RSE Rugged System-On-Module Express). Together with an application-specific carrier board it forms a semicustom solution for industrial, harsh, mobile and mission-critical environments.

The XM1L is controlled by the Intel® Atom™ XL processor, an IA-32 core based on 45nm process technology which is qualified for the industrial temperature range. Due to the power architecture of the Intel® Atom™ CPU, the XM1L has a total power consumption of max. 5 to 7 Watts, while having a clock frequency of up to 1.6 GHz. The XM1L accommodates up to 2 GB of directly soldered main memory and supports other memory like USB Flash on the carrier board.

Interfaces from the Intel® System Controller Hub US15WP are optimized using exclusively modern serial standards and are all routed from the XM1L for availability on any ESMexpress® carrier board. Depending on the version of XM1L, those interfaces include a combination of PCI Express® links, LVDS, SDVO, high-definition audio, SATA, Ethernet with wakeon- LAN functionality, and USB. Additional COM interfaces can be made available on the carrier board via USB to COM conversion.

The XM1L is completed by a board management controller for temperature and power supervision. It comes with a Phoenix® Award BIOS configurable for the final application.

The XM1L is screened or qualified for operation in a -40°C to +85°C conduction or convection cooled environment. As all ESMexpress® modules it is embedded in a covered frame. This ensures EMC protection and allows efficient conductive cooling.

Air cooling is also possible by applying a heat sink on top of the cover. Where operation temperatures are moderate, the module may even do without the frame and cover, with a suitable low-power processor and airflow. ESMexpress® modules are firmly screwed to a carrier board and come with rugged industry-proven connectors supporting high frequency and differential signals. Only soldered components are used to withstand shock and vibration, and the design is optimized for conformal coating. All ESMexpress® modules support a single 95x125mm form factor.

For evaluation and development purposes an ATX carrier board is available. The ESMexpress® module can be evaluated on a COM Express™ carrier board via an adapter from ESMexpress® to COM Express™.

The standard front connectors of the boards are wired to four MIL-C-38999 connectors (three I/O connectors and one power supply connector) at the rear side of the system inside the housing. This enclosure for CompactPCI® cards in 3U format allows to use standard boards that were designed for ventilated systems even in an environment which needs conductive cooling.
