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.
