Stutensee, Germany - With the introduction of MSC Vertriebs GmbH’s EXM32 navigation and communication module at embedded world 2008 (Hall 9, Booth 235), the company's robust CPU modules EXM32-AU1250 or EXM-SH7760 are enhanced with quad band 800/900/1800/1900 MHz EGSM and GPRS as well as with GPS functions. UMTS/HSDPA/EDGE is supported optionally. An external gyro sensor module can be connected for inertial navigation when satellite contact is not available.

Thanks to a special connector technology, the very compact EXM-NAVCOM module, with dimensions of only 65 mm x 90 mm, can be easily mounted on the CPU board. Therefore, powerful navigation, telematics and fleet management systems can be implemented with very little effort. The new module is designed for an extended operating temperature range from -30 to +85°C.

In combination with a suitable GPS/GSM dual antenna, the 16 channel GPS receiver on the EXM-NAVCOM module provides the current position with an accuracy of 2.5 meters (CEP). In steady state condition the calculation of a new position takes less than 1 second, while with good signal strength the “cold start” takes less than 34 seconds. A reliable voice communication is possible via the implemented I²S audio interface. An integrated socket is provided for a SIM card.

The EXM32-AU1250 CPU module from MSC Vertriebs GmbH, designed especially for harsh industrial environment, offers high processing performance and unique multimedia features with extreme low power consumption. The device complies with the EXM32 system-on-module (SOM) standard, developed by MSC. The EXM32-AU1250 is based on the RMI™ Alchemy™ Au1250™ RISC-CPU with 16 kB data and 16 kB instruction cache. It is available in two versions. In the commercial variant, specified for an ambient temperature range from 0 to 70 °C, the processor operates at a clock frequency of 600MHz. The variant for industrial ambient temperature range from -40 to +85°C operates at 500MHz. The powerful CPU module is attached to the carrier board using stable elastomeric connectors.
For applications where computing power and floating-point support are more important than multimedia features, the EXM-SH7760, based on Renesas’ SH7760 RISC CPU, is available from the same module family.

For evaluation and design-in of the EXM32 modules, MSC Vertriebs GmbH provides special development platforms and starter kits. Furthermore, the manufacturer offers support for developing custom-specific carrier boards. In addition to EXM32 modules, the appropriate antenna kit and compatible gyro sensor module are also available from MSC.
