Atmel 公司的ATmega128RFA1是低功耗单片IEEE 802.15.4解决方案,集成了基于AVR增强特性RISC架构的CMOS 8位MCU以及2.4GHz ISM频段的高数据速率收发器.器件的吞吐量达到1MIPS/MHz,无线电收发器的数据数据速率从250kbps到高达2Mbps.ATmega128RFA1广泛应用在ZigBee®/IEEE 802.15.4-2006/2003™, RF4CE, SP100, WirelessHART™,ISM应用以及IPv6/6LoWPAN.本文介绍了ATmega128RFA1主要特性,方框图, AVR架构方框图, 收发器方框图以及基本应用电路图和材料清单(BOM)与扩展特性的应用电路图.

The ATmega128RFA1 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. It is derived from the ATmega1281 microcontroller and the AT86RF231 radio
transceiver.

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.
