Zigbit^™700/800/900 MHz Wireless Modules Overview
2.1 Overview
ZigBit 900 is an extended-range low-power, a low-power, high-sensitivity IEEE 802.15.4/ ZigBee-compli-
ant OEM module, which occupies less than a square inch. Based on a solid combination of Atmel’s latest
MCU Wireless hardware platform [5], power amplifier and low-noise amplifier, the ZigBit 900 offers supe-
rior radio performance, ultra-low power consumption and exceptional ease of integration.

ZigBit 900 contains Atmel’s ATmega1281V Microcontroller [4] and AT86RF212 RF Transceiver [5]. The
module features 128 Kbytes flash memory and 8 Kbytes RAM.
The ZigBit 900 already contains a complete RF/MCU-related design with all the necessary passive com-
ponents included. The module can be easily mounted on a simple 2-layer PCB with a minimum of
required external connection. Compared to a custom RF/MCU design, a module-based solution offers
considerable savings in development time and NRE cost per unit during the design, prototyping, and
mass production phases of product development.
To jumpstart evaluation and development, Atmel also offers a complete set of evaluation and develop-
ment tools. The new ZigBit 900 Development Kit [7] comes with everything you need to create custom
applications featuring ZigBit 900 module.
The kit features MeshBean development boards (ATZB-EVB-900-SMA) with an easy-to-access exten-
sion connector for attaching third party sensors and other peripherals, and a JTAG connector for easy
application uploading and debugging.
The kit also includes reference applications to speed up application development, source code for hard-
ware interface layer and reference drivers for the all the module interfaces, intuitive development
environment from Atmel, and comprehensive set of application notes and product documentation.
