The TQMa28 Minimodule, based on the i.MX28 processor from NXP, offers a balanced ratio between computing and graphic performance. The basis for this is an ARM926 core with up to 450 MHz. The realised memory on the module provides best system support. The module is best suited for smart metering and for easy visualization and control applications. A large number of interfaces and module functions are implemented in the CPU due to the high level of interface and function integration. This allows the basic board to be developed easily and at low-cost. All the processor’s functional pins are on the module plug-in connector. IEC 61850 TQ and SystemCORP provide first-class solutions on the basis of the TQMa28 for intelligent networks on the basis of the IEC 61850 norm. SystemCORP has developed the software stack and adapted to the TQMa28 within the last years from the academic approach to the industrial maturity.

At TQ you not only get first-class embedded systems - we also provide a series of benefits around the embedded module: We support you in defining your requirements for your project. The technical specification serves as guideline for all persons that are involved in the development process. For a fast and easy starting-up we provide starter kits. Through the plug-and-play principle, the software evaluation can be started, if the actual target hardware is not yet available. Due to this a product can be launched faster, reasonably priced and more safely. We support you concerning the selection of components as well as Obsolescence management. Thus your products are protected against obsolete components, complex redesigns, doubtful sources and cost-intensive brokerwares. If desired we arrange a circuit diagram review for your baseboard directly by the developer of the module. Due to the longtime experience of our developers, it happens quite often that entrapments are indentified in the course of the review.Supply of Software, especially Board Support Packages and hardware-close driver for the required operating system. Therefore you shorten your development time and reduce your costs. Starting-up of your baseboard. In case that the starting-up of your baseboard with our module does not work at once, we support you by a structural fault analysis in order to quickly find the reason and repair it. We provide you with reference notes to power-on's e.g. power-on of a CAN controller to the local bus, as well as with application notes.Our Field Application Engineers are pleased to assist you with words and deeds before, during and after your design phase. As system service provider TQ is able to take over the development, production and test of your baseboard. Therefore you get the whole tested unit from one hand. Please just ask us. We are pleased to consult you!
Our Field Application Engineers offer support during all phases of a project, from consulting and design-in to after-sales assistance. Current data sheets and product catalogs can be found in our Download Center.
