The ATZB-RF-233-1-C ZigBit is a compact, low-power, high sensitivity IEEE 802.15.4/ZigBee OEM module with an
integrated FEM built-in. 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-RF-233-1-C Block diagram
.
This ZigBit module contains Atmel’s AT86RF233 2.4GHz 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.

Table 3-4. Region specific TX power settings to ensure Compliance
(1)
.
Note: 1. For detailed characteristics, please refer [4]
2. To ensure compliance, the following regional specific settings are to be ensured:
FCC and IC compliance:
Operating the ZigBit from Channels 12 to 24 has no restrictions on Set power level.
Operating the ZigBit at Channel 11 requires limitation of TX output power to maximum +16dBm, the
power setting register value should be 0x0D or less
Operating the ZigBit at Channel 25 requires limitation of TX output power to maximum +13dBm, the
power setting register value should be 0x0E or less
ETSI Compliance: Operating the ZigBit in Europe requires setting TX Power to 0x0F for Channels 11 and 26.
All other channels can use a power setting of either 0x0E or 0x0F. This setting ensures compliance with ETSI
EN 300 228 clause 4.3.2.2 Maximum Power Spectral Density
The Antenna in this module is designed to provide the best possible LoS range in the direction indicated in this
illustration.
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.
The ZigBit’s location and orientation on the carrier board is illustrated in the above PCB Land pattern and Mounting
information drawing. The Recommended placement of ZigBit on Carrier Board needs to be accurately followed to
ensure performance on the end application
The J-STD-020C-compliant soldering profile is recommended according to Table 3-8.

3.7 Antenna Reference Designs
Multiple factors affect proper antenna match, hence, affecting the antenna pattern. The particular factors are the board
material and thickness, shields, the material used for enclosure, the board neighborhood, and other components
adjacent to antenna. Following guidelines need to be followed when designing the base board for the ZigBit.
General Recommendations:
Metal enclosure should not be used. Using low profile enclosure might also affect antenna tuning.
Placing high profile components next to antenna should be avoided.
Having holes/vias punched around the periphery of the board eliminates parasitic radiation from the board
edges also distorting antenna pattern.
ZigBit module should not be placed next to consumer electronics which might interfere with ZigBit’s RF band
frequency.
The board design should prevent propagation of microwave field inside the board material. Electromagnetic waves of
high frequency may penetrate the board thus making the edges of the board radiate, which may distort the antenna
pattern. To eliminate this effect, metalized and grounded holes/vias must be placed around the board's edges.

4.1 Handling Instructions
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. For products requiring conformal coating, it is advised to suitably mask the ZigBit before applying
the coating to rest of the ZigBit carrier board. To protect ZigBit from humidity, the housing of the product should ensure
suitable Ingress Protection standards are complied with.
The MS-147 connector should never be exposed to Varnish / similar conformal coating material which will affect
electrical connection on the surfaces of connector.
The in-built chip antenna has been tuned for the particular design
4.2 General Recommendations
Metal enclosure should not be used. Using low profile enclosure might also affect antenna tuning
Placing high profile components next to antenna should be avoided
