1. Overview
The USB radio sticks by dresden elektronik provide access to the world of IEEE 802.15.4™
technology by being the gateway to almost any IEEE 802.15.4 Wireless Sensor Networks.
Such gateways can be used for monitoring, sniffing or control of wireless ZigBee®or
6LoWPAN networks and are easily adoptable to custom applications due to the available
free stack software.
The compact designed USB radio sticks deRFusb-23E00 and deRFusb-13E00 contain a
powerful CORTEX-M3 microcontroller with 256 kB high-speed flash. Additional 2GB flash
memory to store user defined data is provided using the USB radio sticks deRFusb-23E06
and deRFusb-13E06, it is usable as mass storage device.
Depending on the transmission frequency of 2.4 GHz - deRFusb-23E00/06/JTAG - or
868/915 MHz - deRFusb-13E00/06/JTAG - the ATMEL low-power transceivers AT86RF231
or alternatively AT86RF212 are integrated. They provide a complete radio transceiver inter-
face between the antenna and the microcontroller and an extended functional range such as
a 128-bit AES hardware engine to ensure data security.
For development the USB radio sticks provide a programming and debugging interface to the
user, by default via native USB. For programming via JTAG, the board options deRFusb-
23E00 JTAG, deRFusb-23E06 JTAG, deRFusb-13E00 JTAG and deRFusb-13E06 JTAG are
advised.

7. Application environment
The USB sticks are designed to connect an IEEE 802.15.4 network with the PC and laptop
environment. Today there are different variants of USB ports on laptop and PC devices. The
USB stick dimension is optimized to plug other USB devices in adjacent ports especially in
horizontal or vertical designed USB hubs.
Generally, the radiation pattern of RF devices depends on the placement and the application
environment. The test measurement and certification process was done with a plugged USB
stick on the side of an USB port of a laptop while the display was open. It is recommended to
plug the USB stick sideways at an USB port of a laptop, if applicable. The use of application
setups like USB hubs or USB extension cables may result in a lower transmit and receive
range.
The USB stick can only be directly plugged into type A ports; into a laptop, PC or hub.

The USB stick has a type A USB plug and an optional 10-pin connector in 1.27 mm pitch for
programming via JTAG interface and tracing via UART. This connector is directly accessible
from the USB stick bottom side, see Figure 10. The internal and external signal connection
to the MCU and transceiver is shown in Table 8. The external available signals are described

9. On-board transceiver
The main difference between the deRFusb-23E00/06/JTAG and the deRFusb-
13E00/06/JTAG USB radio sticks is the built-in 2.4 GHz or alternatively Sub-GHz transceiver
in combination with the appropriate on-board chip antenna. The signal connection between
MCU and transceiver is shown in Table 8.
deRFusb-23E00/06/JTAG - AT86RF231 transceiver
The low-power 2.4 GHz transceiver is designed for industrial and consumer IEEE 802.15.4,
ZigBee, RF4CE, ISA100.11a and high data rate ISM applications. For details refer to [1] in
the reference section.
deRFusb-13E00/06/JTAG - AT86RF212 transceiver
The low-power, low-voltage 800/900MHz transceiver is designed for low-cost IEEE 802.15.4,
ZigBee and high data rate ISM applications available Europe and North America. For details
refer to [2].
9.1. General transceiver description
These single-chip radio transceivers provide a complete radio transceiver interface between
an antenna and a microcontroller.
They comprise the analog radio transceiver and the digital modulation and demodulation in-
cluding time and frequency synchronization and data buffering. The number of external com-
ponents is minimized such that only the antenna, the crystal and decoupling capacitors are
required. The bidirectional differential antenna pins are used for transmission and reception,
thus no external antenna switch is needed.
An internal 128 byte RAM for RX and TX buffers the data to be transmitted or the received
data. Two on chip low dropout voltage regulators provide the internal analog and digital 1.8 V
supply.
The transceivers further contain comprehensive hardware-MAC support (Extended Operat-
ing Mode) and a security engine (AES) to improve the overall system power efficiency and
timing.
