Radio module deRFarm7
25A00
Datasheet
The pluggable radio module deRFarm7-25A00 features
an AT91SAM7X512 microcontroller and a 2.4 GHz trans-
ceiver AT86RF231. The module complies with IEEE
802.15.4 and can be used for ZigBee / 6LoWPAN /
RF4CE or proprietary applications.
The 25A00 module has two 23 pin male connectors
(1.27 mm pitch) which give access to most functions of
the AT91SAM7X512.
The chip ceramic antenna provides a transmitting power
of +2.5 dBm ERP. Distances of more than 200 m can be
reached for line of sight conditions. The integrated trans-
ceiver obtains a receiver sensitivity of –101 dBm. A
hardware 128-Bit AES encryption engine is part of the
transceiver.
The power supply range is from 3.0 VDC to 3.6 VDC with
transmit and receive currents of approx. 45 mA @
12MHz CPU clock. A current consumption of less then
250 µA can be achieved in sleep mode.
Special features of the deRFarm7 module family are the
integrated Ethernet MAC (EMAC) and the integrated
USB device port (UDP)
