MEN Mikro XM51 - ESMexpress® COM with PowerPC® QorIQ™ P4080

Up to 8 Cores, up to 16 GB ECC DDR3 SDRAM


The XM51 is a multi-core computer-on-module based on the Freescale™ PowerPC® QorIQ™ family. Together with an application-specific carrier board it forms a semi-custom solution for industrial, harsh, mobile and mission-critical environments.

The XM51 is built around a QorIQ™ P4080, P4040 or P3041 running at frequencies between 1.2 and 1.5 GHz. All types have multi-core performance and advanced processing functions (incl. encryption), but the XM51 is still scalable to individual needs. The eightcore
P4080 is a high-end number cruncher, while the P3041 aims at power and cost efficiency. The entire board draws a maximum power of 32 W and supports extended operating temperatures in all configurations. The COM has up to 16 GB of soldered ECC main
memory driven by two independent controllers. The two RAM banks can be assigned to processor cores to avoid access conflicts and assure deterministic behavior. This facilitates building up certifiable solutions for safety-critical avionics or railway applications. Up to
512 KB industrial, non-volatile FRAM and 256 MB Flash round out the XM51's onboard memory. Further capacity can be added on the carrier board as needed via high-speed serial busses, i.e. USB or SATA.

All interfaces routed from the QorIQ™ processor are available on any ESMexpress® carrier board. Those include four USB 2.0 host ports and one USB client realized using a UART-to-USB converter, two Gigabit Ethernet channels, dual 3-Gbit SATA, and two PCI Express® x1 links. The latter support PCIe® 2.x with data rates of 5 Gbit/s per lane. The XM51 is qualified for operation in a -50°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. 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 95 x 125 mm 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®.
