2.4 GHz AVR | deRFmega128-22A02

Main component of the affordable and low-power RF module deRFmega128-22A02 is a 2.4 GHz radio transceiver ATmega128RFA1 [datasheet] which has been recently launched by Atmel. It is the single chip solution of a 8Bit-AVR microcontroller

deRFmega128-22A02 is intended for wireless solutions in accordance with the standard IEEE 802.15.4 for ZigBee^®, 6LoWPAN and RF4CE applications. Special features of this module is its compact design and the pluggable application.

The 46 pins of two plug connectors provide full access to all functions of the ATmega128RFA1. A serial EEPROM with the capacity of 1MBit offers high memory capacity e.g. for a firmware update OTA (over the air).

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 receiver sensitivity of –101 dBm giving a link budget of over 103 dB. A hardware 128-Bit AES encryption engine is part of the transceiver.

The power supply range is from 1.8 VDC to 3.6 VDC. In the transmit and receive mode the power consumption is approx. 18 mA, in sleep mode it is less than 2 µA.

deRFmega128-22A02 is certified according to ETSI and FCC (Part-15).
