atzb - rf - 2 12b - 0 - u [ zigbit 900mhz wireless modules ] 42270b ? wireless ? 0 8 / 2014 6 2. zigbit module o verview 2.1 overview the atzb - rf - 2 12b - 0 - u zigbit is a compact, low - power, high sensitivity ieee 802.15.4/zigbee oem module. based o n a solid combination of the latest atmel mcu wireless hardware platform, 900mhz ism band transceiver and atmel studio wireless composer - the zigbit offers an unmatched combination of superior radio performance, ultra- low power consumption and exceptional ease of integration . figure 2 - 1. atzb -rf -2 12b -0 -u user interface diagram this zigbit modu le contains atmel?s at86 rf212b 900mhz ism band transceiver for zigbee and ieee 802.15.4 [1] . the compact all - in - one board design of radio transcei ver with very minimal components on the rf path to antenna connector dramatically improves the zigbit?s compact size, range performance on signal transmission and increases its sensitivity. this ensures stable connectivity within a larger coverage area, an d helps develop applications on smaller footprint. zigbit module contains a complete rf design with all the necessary passive components included. the module can be easily mounted on a simple 2 - layer pcb with a minimum of required external connection. the zigbit module evaluation kit containing the zigbit extension board for the atmel xplained pro hw evaluation platform can be used to develop fw using the atmel studio and evaluate using the wireless composer. compared to a custom rf/mcu solution, a module - based solution offers considerable savings in development time and nre cost per unit during the hw/fw design, prototyping, and mass production phases of product development.
atzb - rf - 2 12b - 0 - u [ zigbit 900mhz wireless modules ] 42270b ? wireless ? 0 8 / 2014 7 depending on end - user design requirements, the zigbit can operate as a sensor no de, where it can be paired with a host processor driving the module over a serial interface. the mac stack running on the host processor can then control data transmission . thus very minimal firmware customization is required for successful module design - in. third - party sensors can then be connected directly to the host mcu. every zigbit module come pre loaded with atmel assigned 64 - bit mac address stored in the eeprom built - in the module . this unique ieee mac address can be used as the mac address of the end product, so there is no need to buy a mac address separately for the product using the zigbit.
