Main component of the pluggable Radio module
deRFmega128-22A022 is Atmel’s ATmega128RFA1 mi-
cro controller. This single chip solution of an 8Bit-AVR
and a 2.4 GHz transceiver is intended for wireless solu-
tions in accordance with the standard IEEE 802.15.4 and
for ZigBee / 6LoWpan / RF4CE applications.
The Radio module 22A022 features two 23 pin male con-
nectors (1.27 mm pitch) which allow full access to all
functions of the Atmega128RFA1. The 22C02 is a sol-
derable variant.
The onboard coaxial jack (U.FL) allows the connection of
different antennas or pigtails. The integrated transceiver
generates +2.4 dBm transmit power and obtains a re-
ceiver sensitivity of –101 dBm giving a link budget of over
103 dB. A hardware 128-Bit AES encryption engine is
part of the transceiver.
A serial 1-Mbit-EEPROM offers high memory capacity
e.g. for a firmware update over-the-air.
The power supply range is from 1.8 VDC to 3.6 VDC. In
the transmitting and receiving mode the power consump-
tion is approx.18 mA, in sleep mode it is less than 2 µA.
