The compact designed USB radio sticks deRFusb-23E00 and deRFusb-13E00 contain a
powerful CORTEX-M3 microcontroller with 256 kBytes High-Speed Flash. Additional 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 - or 868/915 MHz
- deRFusb-13E00/06 - the ATMEL low-power transceivers AT86RF231 or alternatively
AT86RF212 are integrated. They provide a complete radio transceiver interface between the
antenna and the microcontroller and an extended functional range such as a 128-Bit AES
hardware engine to assure data security.
The USB radio sticks provide a programming and debugging interface to the user, by default
via USB.
