Overview
The RCB256RFR2 is designed to provide a reference design for the Atmel ATmega256RFR2
microcontroller and radio transceiver. The IC integrates a powerful, 8-bit AVR
®
RISC microcontroller, an IEEE
802.15.4™-compliant transceiver, and additional peripheral features. The built-in radio transceiver supports the
worldwide accessible 2.4GHz ISM band.
The system is designed to demonstrate standard-based applications such as ZigBee/IEEE 802.15.4, ZigBee RF4CE,
and 6LoWPAN, as well as high data rate ISM applications. The SMA antenna connector allows either operation with the
antenna provided with the RCB or conducted RF performance measurements.
The RF section has been shielded to eliminate interference from sources external to the ATmega256RFR2. To
investigate the reference design area, the shield can be opened by removing the snap-in cover while the RCB is not in
operation.
Most peripheral features of the ATmega256RFR2 are made available through two expansion connectors (EXT0/1).
There are a variety of base boards available for the RCB family.
