Embedded module TQMa28L

with ARM9 based on i.MX28

ARM9 module with i.MX28 from NXP

Embedded module TQMa28L

  • Smallest ARM9 module
  • High quantity use
  • 2x IEEE1588 Ethernet (L2 Switch)
  • Extended temperature range
  • Low power consumption (typ. 1 W)
  • Long-term availability
  • Power management
  • Battery charge functionality
  • IEC 61850 stack

  • Base


    The TQMa28L Minimodule, is the TQMa28 variant without connector and is directly soldered with the baseboard. The BGA module has been developed especially for the use in high volume projects. Due to the high level of integration it is extremely space- and cost-saving. This enables an easy and cost-effective baseboard development. The BGA module is based on the i.MX28 with an ARM926 core with up to 454 MHz. The module is best suited for smart metering and for easy visualization and control applications. The module is Software compatible to the TQMa28. All the processor’s functional pins are on the BGA pins. Note about the ordering information: Further variants are available on request.

    • Extended benefits

      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!
