Radio modules deRFarm7
1. Overview
The compact designed radio modules contains a powerful ARM™7 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

8. Programming
8.1. Required hardware
Dresden elektronik ingenieurtechnik gmbh offers the hardware components for a fast startup.
The following hardware setups are possible:
• deRFarm7 radio module
• deRFgateway or deRFnode (baseboard)
• SEGGER SAM-ICE similar programmer
For example, to exchange the firmware of an ARM-based radio module, use the Atmel SAMICE JTAG Emulator and the SAM-Prog firmware updater. The programmer has to be
plugged to the baseboard which is DC- or USB-powered.

8.2. JTAG interface
All deRFarm7 variants are programmable over JTAG interface (TDI, TDO, TCK, TMS). The
radio module contains all necessary pull-up resistors onboard. Use the pin configuration
shown in Figure 17 to connect the radio module to a suitable ARM™ programmer like the
SEGGER SAM-ICE.

11. Radio certification
11.1. United States (FCC)
The deRFarm7-15A02, deRFarm7-25A00, deRFarm7-25A02, deRFarm7-15C02, deRFarm725C00, deRFarm7-25C02 radio modules comply with the requirements of FCC part 15.
The FCC certification of deRFarm7-25A00, deRFarm7-25A02, deRFarm7-15C02, deRFarm7-25C00, deRFarm7-25C02 radio modules is pending.
To fulfill FCC Certification requirements, an OEM manufacturer must comply with the following 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 deRFarm7-15A02:
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 accept any interference received, including interference that may cause undesired operation.
To be used with the deRFarm7-15A02 modules, the external antenna have been tested and
approved which is specified in here below. The deRFarm7-15A02 modules may be integrated with other custom design antennas which OEM installer must authorize following the FCC
15.21 requirements.
The Original Equipment Manufacturer (OEM) must ensure that the OEM modular transmitter
is labeled with its own FCC ID number. This includes a clearly visible label on the outside of
the final product enclosure that displays the contents shown below. If the FCC ID is not visible when the equipment is installed inside another device, then the outside of the device into
which the equipment is installed must also display a label referring to the enclosed equipment.
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 operated 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 device 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 authorization.

Radio modules deRFarm7
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 reasonable 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 interference 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. European Union (ETSI)
The deRFarm7-15A02, deRFarm7-25A00, and deRFarm7-25A02 modules have been tested
compliant for use in European Union countries.
If the deRFarm7-15A02, deRFarm7-25A00 and deRFarm7-25A02 modules are incorporated
into a product, the manufacturer 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, deRFarm7-25A00 and
deRFarm7-25A02 modules documentation 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 these 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:
• If the CE marking is reduced or enlarged, the proportions given in the above graduated drawing must be respected.
• The CE marking must have a height of at least 5mm except where this is not possible
on account of the nature of the apparatus
• The CE marking must be affixed visibly, legibly, and indelibly.
More detailed information about CE marking requirements you can find at "DIRECTIVE
1999/5/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL" on 9 March 1999
at section 12.
11.3. Approved antennas
The deRFarm7-25A00 has an integrated chip antenna. The design is fully compliant with all
regulations.
The deRFarm7-15A02 has been tested and approved for use with the antenna listed below.
The module may be integrated with other custom design antennas which OEM installer must
authorize with respective regulatory agencies. The used antenna was connected to the radio
module with a 15cm “U.FL-to-SMA pigtail”.
