1. Introduction
1.1 Summary
ATZB-X0-256-4-0-CN ZigBit® is an ultra-compact and low-power 900 MHz IEEE 802.15.4/ZigBee® OEM module from Atmel®. Based on the innovative mixed-signal hardware platform from Atmel, this module uses the ATXMEGA256A3U [1] Microcontroller and AT86RF212B [5] 700/800/900 MHz ISM band Transceiver. The radio transceiver provides high data rates from 20 kb/s up to 1 Mb/s, frame handling, outstanding receiver sensitivity and high transmit output power enabling a very robust wireless communication. The module is designed for wireless sensing, monitoring, control, data acquisition applications, to name a few. This ZigBit module eliminates the need for costly and time-consuming RF development, and shortens time-to-market for wireless applications.
The module has an MS-147 RF connector that can be used as an RF test port. The built-in chip antenna is designed and tuned for the ZigBit design to enable quick integration of the ZigBit into any application.
1.2 Applications
The ZigBit module is compatible with robust IEEE 802.15.4/ZigBee stack that supports a self-healing, self-organizing mesh network, while optimizing network traffic and minimizing power consumption.

2. ZigBit Module Overview
2.1 Overview
The ATZB-X0-256-4-0-CN ZigBit is a compact, low-power, high sensitivity IEEE 802.15.4/ZigBee OEM module. Based on a solid combination of the latest Atmel MCU Wireless hardware platform, 900 MHz 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-X0-256-4-0-CN user interface diagram
.
This ZigBit module contains Atmel’s ATXMEGA256A3U Microcontroller and AT86RF212B 900 MHz ISM band Transceiver for ZigBee and IEEE 802.15.4 [1]. The module features 256KB In-System Self-Programmable flash memory, 16KB SRAM and 4KB EEPROM.
The compact all-in-one board design of MCU and Radio Transceiver with very minimal components on the RF path to
Antenna 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, and helps develop applications on smaller footprint. The MS-147 connector [2] can be used as an RF Test port.
ZigBit Module contains a complete RF/MCU 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.
All ZigBits are preloaded with a Bootloader when they are sold as Modules, either in Single units or T&R.
