 | | AVR2021: AT86RF231 Antenna Diversity (20 pages, revision B, updated 7/08) This application note describes the usage, design, and layout of the AT86RF231 Antenna Diversity. The information provided is intended as a helping hand for hardware designers to make use of the AT86RF231 Antenna Diversity capabilities. |
 |  | AVR2022: AT86RF231 - Software Programming Model (5 pages, revision A, updated 5/08) The AT86RF231 Software Programming Model (SWPM) provides a reference for developers utilizing the AT86RF231 radio transceiver as effective as possible. |
 | | AVR2023: AT86RF231 PCB reference design for antenna diversity (15 pages, revision A, updated 8/08) The AT86RF231 diversity board demonstrates the capabilities of the 802.15.4 compliant 2.4 GHz radio transceiver AT86RF231. With the high performance ATmega1281V AVR microcontroller it serves as a full function network node that is capable of hosting a MAC implementation driven by two AAA batteries for more than one year. Two ceramic chip antennas increase the link budget in a typical indoor scenario with multipath fading effects. |
 | | AVR2027: AES Security Module (23 pages, revision A, updated 9/09) This document briefly reviews IEEE 802.15.4 /ZigBee® cryptography and shows how the AT86RF231's and AT86RF212's security modules simplify the implementation of these features. |
