The AT86RF212 is a low-power, low-voltage 700/800/900 MHz transceiver specially
designed for the IEEE Standard 802.15.4, ZigBee, 6LoWPAN, and high data rate ISM
applications. For the sub-1 GHz bands, it supports low data rates (20 and 40 kbit/s) of
the IEEE Standard 802.15.4-2003 [2] and provides optional data rates (100 and 250
kbit/s) using O-QPSK, according to the IEEE Standard 802.15.4-2006 [1] and the
respective IEEE P802.15.4c Draft Amendment [3]. Furthermore, proprietary High Data
Rate Modes up to 1000 kbit/s can be employed.
The AT86RF212 is a true SPI-to-antenna solution. RF-critical components except the
antenna, crystal, and de-coupling capacitors are integrated on-chip. MAC and AES
hardware accelerators improve overall system power efficiency and timing...
