MM50 ESMini module

Expanding its ESMini family, MEN Micro Inc. has released the MM50 that incorporates the high processing capabilities and power dissipation of PowerPC into a flexible, compact computer-on-module (COM) board.

The MM50 ESMini module uses a PowerPC MPC5121e or a MPC5123 processor, each based on an e300 processor core incorporating a memory management unit (MMU) and a floating point unit (FPU) as well as a powerful 760 MIPS using clock frequencies of up to 400MHz.

The rugged, ultrasmall form factor module is well-suited for use in mobile applications. The processor's e300 core pairs a display interface unit, with or without a 3D graphics engine, and integrated I/O features with low power of up to 3W maximum.

The MM50's soldered 512MB of DDR2 SDRAM withstands severe shock of 15g, 11ms, bump of 10g, 16ms and vibration of 1g from 10Hz to 150Hz (sinusoidal). The MM50 also provides up to 128KB of non-volatile ferroelectric RAM and mass storage expansion through SDHC on the carrier board.

In addition to serial I/O interfaces, such as USB, the MM50 also features legacy interfaces including CAN bus, COM, Fast Ethernet, I²C and GPIO. Six individually programmable controllers give further flexibility to implement serial I/O.

As with all ESMini modules, the MM50 operating temperature is from -40°C to +85°C. An optional version with a conduction-cooling frame gives each ESMini module full EMC protection. The module can be used without an enclosure as well.

ESMini modules, which measure 95mm x 55mm, are firmly screwed to a carrier board and come with rugged, railway-compliant connectors with differential signals. By standard, only soldered components are used to withstand shock and vibration, and the design is optimised for conformal coating.

The MEN Micro XC4 evaluation carrier board in microATX format is used to test all of the MM50's functions and to develop a specific application.

Pricing for the ESMini module is Rs.17,627.65 ($384). Delivery is four to six weeks ARO.
