Note:
The large center pad underneath the QFN/MLF package is made of metal and internally connected
to AVSS. It should be soldered or glued to the board to ensure good mechanical stability. If the
center pad is left unco
nnected, the package might loosen from the board. It is not recommended to
use the exposed paddle as a replacement of the regular AVSS pins.

Typical values contained in this datasheet are based on simulation and characterization
results of other AVR microcontrollers and radio transceivers manufactured in a similar
process technology. Minimum and Maximum values will be available after the device is
characterized.

ATmega256/128/64RFR2
3 Overview
The ATmega256/128/64RFR2 is a low-power CMOS 8-bit microcontroller based on the
AVR enhanced RISC architecture combined with a high data rate transceiver for the 2.4
GHz ISM band.
By executing powerful instructions in a single clock cycle, the device achieves
throughputs approaching 1 MIPS per MHz allowing the system designer to optimize
power consumption versus processing speed.
The radio transceiver provides high data rates from 250 kb/s up to 2 Mb/s, frame
handling, outstanding receiver sensitivity and high transmit output power enabling a
very robust wireless communication.
3.1 Block Diagram
Figure 3-1 Block Diagram
The AVR core combines a rich instruction set with 32 general purpose working
registers. All 32 registers are directly connected to the Arithmetic Logic Unit (ALU). Two
independent registers can be accessed with one single instruction executed in one
clock cycle. The resulting architecture is very code efficient while achieving throughputs
up to ten times faster than conventional CISC microcontrollers. The system includes
internal voltage regulation and an advanced power management. Distinguished by the
small leakage current it allows an extended operation time from battery.
The radio transceiver is a fully integrated ZigBee solution using a minimum number of
external components. It combines excellent RF performance with low cost, small size
and low current consumption. The radio transceiver includes a crystal stabilized
fractional-N synthesizer, transmitter and receiver, and full Direct Sequence Spread
