    This appendix lists general specifications and power characteristics for MBX series embedded controllers. It also describes cooling requirements and FCC compliance. A complete functional description of the MBX series embedded controller appears in Chapter 5, Functional Description. Specifications for the optional expansion modules can be found in the documentation for those modules.
  • Page 102: Power Requirements

    Specifications Power Requirements Power requirements for the MBX embedded controller depend on the configuration of the module. You can determine the power requirements specific to your application by adding the appropriate values from the following tables. The first table specifies the minimum power consumption of the standard configuration assuming 16MB of on-board DRAM.
  • Page 103: Cooling Requirements

    3.78 W Cooling Requirements The Motorola MBX series family of embedded controllers is specified, designed, and tested to operate reliably with an incoming air temperature range from 0° C to 70° C (32° F to 158° F) with forced air cooling of the entire assembly (base board and expansion modules) at a velocity typically achievable by using a 100 CFM axial fan.
  • Page 104 Specifications and 490 LFM flowing over the module. Less airflow is required to cool the module in environments having lower maximum ambient temperature. Under more favorable thermal conditions, it may be possible to operate the module reliably at higher than 70° C with increased airflow. It is important to note that there are several factors, in addition to the rated CFM of the air mover, which determine the actual volume and speed of air flowing over a module.
