1. Introduction

1.1 Summary

ATZB-RF-212B-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 AT86RF212B [4] 700/800/900 MHz ISM band Transceiver alone on a very compact Module design that provides the customer to integrate the module to any of the recommended Atmel’s Microcontrollers that the application fits. 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 timeconsuming 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-RF-212B-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-RF-212B-0-CN Block diagram

This ZigBit module contains Atmel’s AT86RF212B 900 MHz ISM band Transceiver for ZigBee and IEEE 802.15.4 [1]. The compact board design of the 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 [1] can be used as an RF Test port.

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.

Depending on end-user design requirements, the ZigBit can operate as a self-contained sensor node, where it would 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 and manages module peripherals. Thus very minimal firmware customization is required for successful module design-in. Third-party sensors can then be connected directly to the module, thus expanding the existing set of peripheral interfaces.

Every ZigBit Module come pre loaded with Atmel assigned 64-bit MAC address stored in the signature bytes of the device. 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.
