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.

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.

3.5 Mounting Information The Figure below shows the PCB layout recommended for a ZigBit module. Neither via-holes nor wires are allowed on the PCB upper layer in the area occupied by the module. As a critical requirement, RF_GND pins should be grounded via several via-holes to be located right next to the pins thus minimizing inductance and preventing both mismatch and losses. Figure 3-1.

Handling Instructions 4.1 The ZigBit Modules are fixed with an EMI Shield to ensure compliance to Emission and Immunity rules. This shield is galvanic and NOT air tight. So cleaning of the module with IPA / other similar agents is not advised. Humidity protection coating (conformal) will cause deviated RF behavior and coating material being trapped inside EMI Shield. So this should be avoided.

Special commands are available to erase and write data to user signature pages via the JTAG interface (see section on "Programming via the JTAG Interface" in Atmega256RFR2 datasheet [1] for details). User signature rows can be read from software in the same way as the device and JTAG identifiers (see section "Reading the Signature Row from Software" of Atmega256RFR2 datasheet[1]). Note: 1 The MAC address stored inside the MCU is a uniquely assigned ID for each ZigBit and owned by Atmel.
