Overview The compact designed radio modules contains a powerful ARM7 microcontroller with 512 kBytes High-Speed Flash, On-chip USB 2.0 Full Speed Transceiver, Ethernet MAC 10/100 base-T in RMII-Mode and an onboard transceiver for 2.4 GHz or 868/915 MHz. The 46 pin interface gives access to most hardware functions of the microcontroller. A long radio transmission range can be achieved by using the coaxial jack (U.FL) version with an external antenna attached. In the Sub-GHz band several hundred meters (100 m = 330 feet) can be reached without problems. The 2.4 GHz version is able to cover up to 200 m (650 feet) with a ceramic chip antenna. All versions have a 128-bit AES encryption unit installed. The 512 kB Flash and 128 kB RAM of the deRFarm7 modules provide enough resources to be used for any tasks within a wireless sensor network. 2. Application The main applications for the deRFarm7 radio modules are:  2.4GHz IEEE 802.15.4  868MHz / 915MHz IEEE 802.15.4  ZigBee® Pro  ZigBee® RF4CE  ZigBee® IP  6LoWPAN  Wireless Sensor Networks (WSN)  industrial and home controlling and monitoring  Gateway applications between IEEE 802.15.4 and other networks, e.g. Ethernet

Programming example The described programming examples was done with Atmel‟s programming software „SAM-BA v2.10‟, which is free downloadable on Atmel homepage. Install SAM-BA v2.10 on the PC or Laptop and connect the hardware described in section 8.1. 1. Start SAM-BA v2.10 The start screen (Figure 17) shows two selection tables. At first choose the connect-ed SEGGER-SAM-ICE programmer (Figure 18) and then the connected board (Figure 19). In this case the assembled MCU is important for selection, that means choose AT91SAM7X512-EK.

To fulfill FCC Certification requirements, an OEM manufacturer must comply with the follow-ing regulations: The modular transmitter must be labeled with its own FCC ID number, and, if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following. Any similar wording that expresses the same meaning may be used. Sample label for radio module deRFarm7-25A00 and deRarm7-25C00: FCC-ID: XVV-ARM725A00 This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must ac-cept any interference received, including interference that may cause undesired operation. Sample label for radio module deRFarm7-25A02 and deRarm7-25C02: FCC-ID: XVV-ARM725A02 This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must ac-cept any interference received, including interference that may cause undesired operation. Sample label for radio module deRFarm7-15A02: FCC-ID: XVV-ARM715A02 This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must ac-cept any interference received, including interference that may cause undesired operation.

This equipment complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation (FCC 15.19). The internal / external antenna(s) used for this mobile transmitter must provide a separation distance of at least 20 cm from all persons and must not be co-located or oper-ated in conjunction with any other antenna or transmitter. Installers must be provided with antenna installation instructions and transmitter operating conditions for satisfying RF exposure compliance. This device is approved as a mobile de-vice with respect to RF exposure compliance, and may only be marketed to OEM installers. Use in portable exposure conditions (FCC 2.1093) requires separate equipment authoriza-tion. Modifications not expressly approved by this company could void the user's authority to operate this equipment (FCC section 15.21). This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasona-ble protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful inter-ference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense (FCC section 15.105). 11.2.

If the deRFarm7-15A02, deRFarm7-15C02, deRFarm7-25A00, deRFarm7-25C00, deR-Farm7-25A02 and deRFarm7-25C02 modules are incorporated into a product, the manufac-turer must ensure compliance of the final product to the European harmonized EMC and low-voltage/safety standards. A Declaration of Conformity must be issued for each of these standards and kept on file as described in Annex II of the R&TTE Directive. The manufacturer must maintain a copy of the deRFarm7-15A02, deRFarm7-15C02, deR-Farm7-25A00, deRFarm7-25C00, deRFarm7-25A02 and deRFarm7-25C02 modules docu-mentation and ensure the final product does not exceed the specified power ratings, antenna specifications, and/or installation requirements as specified in the user manual. If any of the-se specifications are exceeded in the final product, a submission must be made to a notified body for compliance testing to all required standards. The “CE“ marking must be affixed to a visible location on the OEM product. The CE mark shall consist of the initials "CE" taking the following form:
