LONDON MSC Vertriebs GmbH has decided to open up its EXM32 system-on-module (SOM) specification to enable other companies to design and market EXM32-based products.
An EXM32 consortium has been formed and in addition to MSC Vertriebs (Stutensee, Germany), Displaign Elektronik & Design GmbH, Linutronix GmbH, MicroDoc Computersysteme GmbH, Synergetik Gesellschaft für Industriesensorik mbH and TRS-STAR GmbH have joined the EXM32 user and manufacturer consortium.
The EXM32 CPU Module Design Specification, an EXM32 Baseboard Design Guide is also available at www.EXM32.org for download. Schematics of a baseboard are available for registered members.
The EXM32 modules have a form factor of 65 mm x 90 mm designed for demanding environmental conditions. It is specified for an extended temperature range from -40°C to +85°C. The devices feature a high resistance to shock and vibration and meet the automotive specification DIN EN 60068 (Environmental Conditions for Electrical and Electronic Equipment for Road Vehicles).
The EXM32 modules can be mounted on the baseboard using elastomeric contact strips which serve as connector elements. These strips are compressed between the gold-plated contact zones of the boards to be connected and secured by screws. The connection elements have chambers, which contain an elastic material with a large number of fine gold wires. These wires are pressed into the gold-plated contact zones and thereby provide a reliable electrical contact. The contact can not be impaired by surface contamination or the subsequent application of a coating, it is hermetically sealed off from environmental influences.
A series of CPU and interface modules, compliant with the EXM32 specification, are already available from MSC. These include the EXM32-AU1250 CPU module with excellent multimedia features, the high-performance EXM-SH7760 devices as well as the EXM-NAVCOM navigation and communication module with GPRS and GPS functionality.
