1. Introduction

1.1 Summary

ATZB-S1-256-3-0-U ZigBit® is an ultra-compact and low-power 2.4GHz IEEE 802.15.4/ZigBee® OEM module from
Atmel®. Based on the innovative mixed-signal hardware platform from Atmel, this module uses the ATmega256RFR2
SoC with the AVR 8-Bit Microcontroller and a high data rate transceiver for the 2.4GHz ISM band. The radio transceiver
provides high data rates from 250kb/s up to 2Mb/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 U.FL RF connector that can be used to connect any of the approved antenna – cable assembly.
This give freedom to applications to choose the external antenna1 that can be mounted on an end product.

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-S1-256-3-0-U ZigBit is an ultra 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, 2.4GHz 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-S1-256-3-0-U Block Diagram.

This ZigBit module contains the Atmel ATmega256RFR2 Microcontroller and a 2.4GHz ISM band Transceiver for
ZigBee and IEEE 802.15.4 [1]. The module features 256KB In-System Self-Programmable flash memory, 32KB SRAM
and 8KB EEPROM.

The compact all-in-one integration of MCU and Radio Transceiver inside the chip along 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.

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.
Depending on end-user design requirements, the ZigBit can operate as a self-contained sensor node, where it would

function as a single MCU, or 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 and manages module peripherals.
Thus very minimal firmware customization is required for a 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.
