The ATmega128RFA1 features a low-power 2.4 GHz radio transceiver designed for
industrial and consumer ZigBee/IEEE 802.15.4, 6LoWPAN, RF4CE and high data rate
2.4 GHz ISM band applications. The radio transceiver is a true peripheral block of the
AVR microcontroller. All RF-critical components except the antenna, crystal and de-
coupling capacitors are integrated on-chip. Therefore, the ATmega128RFA1 is
particularly suitable for applications like:
• 2.4 GHz IEEE 802.15.4 and ZigBee systems
• 6LoWPAN and RF4CE systems
• Wireless sensor networks
• Industrial control, sensing and automation (SP100, WirelessHART)
• Residential and commercial automation
• Health care
• Consumer electronics
• PC peripherals
This radio transceiver is part of a system-on-chip solution with an AVR
It comprises a complex peripheral component containing the analog radio, digital
modulation and demodulation including time and frequency synchronization and data
buffering. The number of external components for the transceiver operation is
minimized such that only the antenna, the crystal and decoupling capacitors are
required. The bidirectional differential antenna pins (RFP, RFN) are used for
transmission and reception, thus no external antenna switch is needed.
