3.5 Configuration summary

ATmega2564/1284/644RFR2
8
The port G2 is not connected to a pin in the ATmega2564/1284/644RFR2. The
alternate pin function AMR (asynchronous automated meter reading input to timer 2) is
not available.
The port G5 is not connected to a pin in the ATmega2564/1284/644RFR2. The
alternate pin function OC0B (output compare channel of 8-Bit timer 0) is not available.
The RSTON reset output signaling the internal reset state is not connected to a pin in
the ATmega2564/1284/644RFR2.
According to the application requirements a variable memory size allows to optimize
current consumption and leakage current.

The devices are optimized for applications based on the ZigBee and the IEEE 802.15.4
specification. Having application stack, network layer, sensor interface and an excellent
power control combined in a single chip many years of operation should be possible.
