AT86RF231
An internal 128-byte RAM for RX and TX (Frame Buffer) buffers the data to be transmitted or the
received data.
The configuration of the AT86RF231, reading and writing of Frame Buffer is controlled by the
SPI interface and additional control lines.
The AT86RF231 further contains comprehensive hardware-MAC support (Extended Operating
Mode) and a security engine (AES) to improve the overall system power efficiency and timing.
The stand-alone 128-bit AES engine can be accessed in parallel to all PHY operational transac-
tions and states using the SPI interface, except during SLEEP state.
For applications not necessarily targeting IEEE 802.15.4 compliant networks, the radio trans-
ceiver also supports alternative data rates up to 2 Mb/s.
For long-range applications or to improve the reliability of an RF connection the RF performance
can further be improved by using an external RF front-end or Antenna Diversity. Both operation
modes are supported by the AT86RF231 with dedicated control pins without the interaction of
the microcontroller.
Additional features of the Extended Feature Set, see
Section 11. “AT86RF231 Extended Fea-
ture Set” on page
128, are provided to simplify the interaction between radio transceiver and
microcontroller.
