Based on a solid combination of Atmel's latest MCU Wireless hardware platform, power amplifier and low-noise amplifier, the ZigBit Amp offers an unmatched combination of superior radio performance, ultra-low power consumption and exceptional ease of integration. Figure 2-1.

ceiver [5]. The module features 128K bytes flash memory and 8K bytes RAM. The compact all-in-one-chip integration of output Power Amplifier and input Low-Noise Amplifier, along with RF switches enables digital control of an external RF front-end to dramatically improve ZigBit's range performance on signal transmission and increase its sensitivity. This ensures stable connectivity with larger coverage area without significant increase in module size. The HF U.FL coaxial connector [6]

used in the ATZB-A24-UFL module enables the user to choose appropriate external antenna for every type of application. ZigBit Amp already 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 exter-

nal connection. Compared to a custom RF/MCUsolution, a module-based solution offers considerable savings in development time and NRE cost per unit during the design, prototyping, and mass production phases of product development. ZigBit 2.4 GHz Amplified Wireless Modules 2-5 8228BMCU Wireless06/09 Zigbit Module Overview To jumpstart evaluation and development, Atmel also offers a complete set of evaluation and develop-

ment tools. The new ZigBit Amp Development Kit [7] (ATZB-DK-A24) comes with everything you need to create custom applications featuring ZigBit Amp module. The kit features MeshBean development boards with an easy-to-access extension connector for attach-

ing third party sensors and other peripherals, and a JTAG connector for easy application uploading and debugging. The kit also includes reference applications to speed up application development, source code for hard-

ware interface layer and reference drivers for the all the module interfaces, intuitive development environment from Atmel, and comprehensive set of application notes and product tutorials. ZigBit Amp modules comes bundled with BitCloud, a 2nd generation embedded software stack from Atmel. BitCloud is fully compliant with ZigBee PRO and ZigBee standards for wireless sensing and con-

trol [7], [8], [9], and it provides an augmented set of APIs which, while maintaining 100% compliance with the standard, offer extended functionality designed with developer's convenience and ease-of-use in mind. Depending on end-user design requirements, ZigBit Amp 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. In the former case, a user application may be used with the BitCloud software allowing customization of embedded applications through BitCloud's C API. In the latter case, the host processor controls data transmission and manages module peripherals via an extensive set of SerialNet AT commands. Thus, no firmware customization is required for a successful module design-in. Additionally, third-party sensors can be connected directly to the module, thus expanding the existing set of peripheral interfaces.

1. The UART_TXD pin is intended for input (i.e. its designation as "TXD" implies some complex system containing ZigBit Amp as its RF terminal unit), while UART_RXD pin, vice versa is for output. 2. Most of pins can be configured for general purpose I/O or for some alternate functions as described in details in the ATmega1281V Datasheet [3]. 3. GPIO pins can be programmed either for output, or for input with/without pull-up resistors. Output pin drivers are strong enough to drive LED displays directly (refer to figures on pages 387-388, [3]). 4. All digital pins are provided with protection diodes to D_VCC and DGND 5. It is strongly recommended to avoid assigning an alternate function for OSC32K_OUT pin because it is used by BitCloud. However, this signal can be used if another peripheral or host processor requires 32.768 kHz clock, otherwise this pin can be disconnected. 6. Normally, JTAG_TMS, JTAG_TDI, JTAG_TDO, JTAG_TCK pins are used for on-chip debugging and flash burning. They can be used for A/D conversion if JTAGEN fuse is disabled. 7. The following pins can be configured with the BitCloud software to be general-purpose I/O lines:

GPIO1, GPIO2, GPIO3, GPIO4, GPIO5, GPIO6, GPIO7, GPIO8, GPIO_1WR, I2C_CLK, I2C_DATA, UART_TXD, UART_RXD, UART_RTS, UART_CTS, ADC_INPUT_3, ADC_INPUT_2, ADC_INPUT_1, BAT, UART_DTR, USART0_RXD, USART0_TXD, USART0_EXTCLK, IRQ_7, IRQ_6. Additionally, four JTAG lines can be programmed with software as GPIO as well, but this requires changing the fuse bits and will disable JTAG debugging. 8. With BitCloud, CTS pin can be configured to indicate sleep/active condition of the module thus provid-

ing mechanism for power management of host processor. If this function is necessary, connection of this pin to external pull-down resistor is recommended to prevent the undesirable transients during module reset process. ZigBit 2.4 GHz Amplified Wireless Modules 3-12 8228BMCU Wireless06/09 9. Using ferrite bead and 1 F capacitor located closely to the power supply pin is recommended, as shown below. Specifications 10. Pins 48, 49 and 50 are featured for ATZB-A24-U0 module only. 11. In SPI mode, USART0_EXTCLK is output. In USART mode, this pin can be configured as either input or output pin. ZigBit 2.4 GHz Amplified Wireless Modules 3-13 8228BMCU Wireless06/09 3.4 Mounting Information The below diagrams show the PCB layout recommended for ZigBit Amp module. Neither via-holes nor wires are allowed on the PCB upper layer in area occupied by the module. As a critical requirement, RF_GND pins should be grounded via several holes to be located right next to pins thus minimizing inductance and preventing both mismatch and losses. Figure 3-4. ATZB-A24-UFL/U0 PCB Recommended Layout, Top View Specifications 3.5 Soldering Profile The J-STD-020C-compliant soldering profile is recommended according to Table 3-7. Table 3-7.

1. The package is backward compatible with PB/Sn soldering profile. ZigBit 2.4 GHz Amplified Wireless Modules 3-14 8228BMCU Wireless06/09 3.6 Antenna Reference Design Specifications 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. 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 punched around the periphery of the board eliminates parasitic radiation from the board edges also distorting antenna pattern.

ZigBit Amp module should not be placed next to consumer electronics which might interfere with ZigBit Amp's RF frequency band. The board design should prevent propagation of microwave field inside the board material. Electromag-

netic 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 must be placed around the board's edges.

FCC Certification Scenarios for Atmel ZigBits on Customers' products Features Covers FCC certification scenarios for Atmel ZigBits usage Analyzes the custom products possibilities and likely-hoods for successful certification 1 Introduction Atmels Wireless applications play vital role in providing IEEE 802.15.4 compliant, ZigBee, and 6LoWPAN wireless solutions using family of RF devices such as ZigBits, AT86RFxxx,and MegaRF single chip solutions. These devices are purely based on Atmels wide range of high performance, low-power IEEE 802.15.4-compliant transceivers for the regional 700/800/900MHz frequency bands available in Europe and North America, and the 2.4GHz band available world wide. 8-bit Microcontrollers Application Note Rev. [0.5]-AVR-[09/10]

2 Overview This application note describes an overview of the Certification Scenarios possible when a designer uses the Atmel ZigBits portfolio. It also covers the changes that affect Atmels existing certification due to minor or major changes on designers hardware. 3 Atmels Range of ZigBit Modules and usage scenarios in customer products 3.1 ATZB-24-A2 It is a ZigBit Module with Dual Chip Antenna, a low-power, 802.15.4 ZigBee module combination with the popular ATmega1281V MCU and the Atmel AT86RF230 radio transceiver. The ATZB-24-A2 comes with a Dual Chip Antenna and eliminates the need for costly and time-consuming RF development and shortens time to market, while embedded 802.15.4/ZigBee software ensures standards-based wireless connectivity for a wide range of applications. Figure 3-1. ATZB-24-A2 3.1.1 Certification scenarios 3.1.2 Scenario # 1 2 AVR[appn ote nr]

The following scenario explains the usage of the ATZB-24-A2 module with the customers base board. The ATZB-24-A2 module is bought by a designer and used on the base board. When designers use the ATZB-24-A2 module on their base board and if the product does not have any other radiating circuits, the designer need not re-certify the complete product. In this case the designer has to mention on a visible area in their product that Product carries FCC module with FCC ID VW4A090664.

[doc nr]-AVR-[mm]/[yy]

3.1.3 Scenario # 2 3.2 ATZB-A24-UFL AVR[appnote nr]

When designers use the ATZB-24-A2 module on their base board and if there are additional circuits on the base board, with the additionally added circuits comprising of another radio or switching circuits, the radiations caused by the new circuits may or may not affect the performance of the ATZB-24-A2. If the ATZB-24-A2 does not get affected by the additional circuits, still there are possibilities that there could be emissions from these circuits that are out of limits specified by part 15.247. If these additional circuits are designed to operate within compliance limits, then the probability of successful certification is high. For more information on the type of additional circuits, please refer appendix A. The FCC ID of ATZB-24-A2 is VW4A090664. Customers have to mention Product carries Module with FCC ID VW4A090664 on their product containing the ATZB-24-

ZigBit Amp ATZB-A24-UFL is an amplified IEEE 802.15.4/ZigBee module. Its unique RF design achieves a rare combination of the industry-leading range performance and low power consumption. The ATZB-A24-UFL modules small footprint of less than a square inch of space makes the integration easy, with the built-in U.FL antenna connector. Figure 3-2. ATZB-A24-UFL 3.2.1 Certification scenarios 3.2.2 Scenario # 1

[doc nr]-AVR-[mm]/[yy]

The following scenarios explain the usage of the ATZB-A24-UFL module on customers base board. The ATZB-A24-UFL module is bought by a designer and used on the base board. Atmels ATZB-A24-UFL Module has been certified under Limited Modular category of FCC part 15 subpart C, limited modular certification applies to modules that do not fully meet the requirements for a single modular certification. Host-manufacturer must ensure that the end-user of the host that will finally carry the module has no access to 3 3.2.3 Scenario # 2 3.3 ATZB-24-B0 the antenna connectors, because they are standard connectors. The position of the Antenna cable is not really fixed as part of this product, and hence the module must be re-certified. If there are additional circuits on the base board, with the additionally added circuits comprising of another radio or switching circuits, the radiations caused by the new circuits may or may not affect the performance of the ATZB-A24-UFL. If the ATZB-

A24-UFL does not get affected by the additional circuits, still there are possibilities that there could be emissions from these circuits that are out of limits specified by part 15.247. If these additional circuits are designed to operate within compliance limits, then the probability of successful certification is high. For more information please refer appendix A. Designers may want to use the ATZB-A24-UFL on the base board and / or use UFL antenna adaptor and take out the RF signal to a different antenna connector. Sometimes customers may have requirement to use higher gain antenna than an antenna with 0dBi gain as mentioned in sec 3.2.2. In such case designer is expected to ensure that the compliance of the additional circuits are taken care while re-

certifying the end product with ATZB-A24-UFL. Refer appendix A. for detailed information about additional circuits on base board. The FCC ID of ATZB-A24-UFL is VW4A090668. Customers have to mention Product carries Module with FCC ID VW4A090668 on their product containing the ATZB-

A24-UFL ZigBits. The ZigBits FCC ID cannot be used in replacement of the final products FCC ID, since there is a requirement to have separate FCC ID for the entire product. ATZB-24-B0 ZigBit Module with Balanced RF Output is a low-power, 802.15.4/

ZigBee module, combination of the ATmega1281V MCU and the AT86RF230 radio transceiver. ATZB-24-B0 module is very similar to the ATZB-24-A2 module and unlike ATZB-24-A2 module it offers the flexibility of adding design oriented external antenna in the application board. ATZB-24-B0 minimizes bill of materials (BOM) and shortens time to market, while embedded 802.15.4/ ZigBee software ensures standards-based wireless connectivity for a wide range of applications. 4 AVR[appn ote nr]

The following scenarios explain the usage of the ATZB-24-B0 module on customers base board. The ATZB-24-B0 module is bought by designers and used on a base board. Atmels ATZB-24-B0 Module has been certified under Limited Modular category of FCC part 15 subpart C. Limited modular certification applies to modules that do not fully meet the requirements for a single modular certification. The ATZB-24-B0 module meets all but the requirement of having an on-board antenna or connector. Designers are required to re-certify their products carrying this module as this module brings out the Balanced RF Output without ending up in any antenna structure on the module. Since there is RF signal flowing on the designers base board in such case, the entire product has to be re-tested and certified. The new FCC ID obtained by the designer has to be used to meet regulatory requirements. By following the recommended design to connect the RF signal from B0 Module pins to the Antenna, the probability of success in Re-certification tests is very high. This is because the module has been successfully certified with Atmels Base board reference. The Base board reference design that applies for the ATZB-24-B0 is ATZB-EVB-24-SMA. In cases were usage explained in Scenario #1 applies and additionally, application dependent circuits as explained in Appendix A is used on the Base board, this scenario applies. If the circuits on the customers base board are either Intentional or Unintentional Radiators or both, then the customer has to certify the entire product carrying the ATZB-24-B0 Module. The probability of a successful certification lies with how good or bad, the additional circuits on base board are designed in terms of regulatory compliance. Atmels Base board reference design- ATZB-EVB-24-SMA in this case can help customers in assuring success in the module related tests alone. 5 3.4 ATZB-900-B0 ATZB-900-B0 is an ultra-compact, low-power, high-sensitivity 868MHz / 915MHz 802.15.4/ZigBee OEM module from Atmel.

The following scenarios will explain the changes that can be done on the ATZB-A24-

U0 module and / or on their carrier boards on customers base board. The ATZB-A24-U0 module is bought by designers and used on customers base board. Atmels ATZB-A24-U0 Module has been certified under Limited Modular category of FCC part 15 subpart C. Limited modular certification applies to modules that do not fully meet the requirements for a single modular certification. The ATZB-A24-U0 module meets all but the requirement of having an on-board antenna or connector. 7 3.5.3 Scenario # 2 Designers are required to re-certify their products carrying this module as this module brings out the UnBalanced RF Output without ending up in any antenna structure on the module. Since there is RF signal flowing on the designers base board in such case, the entire product has to be re-tested and certified. The new FCC ID obtained by the designer has to be used to meet regulatory requirements. By following the recommended design to connect the RF signal from U0 Module pin to the Antenna, the probability of success in Re-certification tests is very high. This is because the module has been successfully certified with Atmels Base board reference. The Base board reference design that applies for the ATZB-A24-U0 is ATZB-EVB-A24-SMA. The recommended antenna gain for ATZB-A24-U0 on a baseboard is less than or equal to 0dBi. In cases were usage explained in Scenario #1 applies and additionally, application dependent circuits as explained in Appendix A is used on the Base board OR antenna with gain of more than 0dBi (directional antenna) is used, this scenario applies. If the circuits on the customers base board are either Intentional or Unintentional Radiators or both, then the customer has to certify the entire product carrying the ATZB-A24-U0 Module. The probability of a successful certification lies with how good or bad, the additional circuits on base board are designed in terms of regulatory compliance. Atmels Base board reference design- ATZB-EVB-A24-SMA in this case can help customers in assuring success in the module related tests alone. 4 Country Specific certifications 4.1 Japan The ZigBits that are intended to use in Japan must be certified with TELEC certification system. TELEC is the major organization providing the certification services as a registered certification body. FCC approval and CE declaration are not recognized by TELEC. TELEC certification requires the ZigBits to be tested and certified in an accredited test lab within Japan according to TELEC standards. The probability of getting certified is high if the products already hold FCC / CE certification, since the TELEC specifications on the limits are similar to FCC/CE. Refer RF TELEC standard for more details. The ZigBits and the ZigBits products that are to be used in Korea must be certified with KCC (Korea Communications Commission) certification body. KCC is the institution providing the certification services as a registered certification body. The product which even passes the FCC / CE certification must undergo in-country testing and certification. But the probability of getting certified is high in case if the products already hold FCC / CE certification.

In Taiwan, NCC (National Communications Commission) approval is required for the end product using ZigBits. In-country testing is required since FCC / CE certifications are not accepted. ETSI / FCC will be the reference standard for certification regulations. The probability of getting certified is high in case if the products already hold FCC / CE certification. The ZigBits and the ZigBits products that are to be used in China must under go in-

country certification as mentioned by SRRC (State Radio Regulatory Committee). SRRC is a radio management of P.R China. The product which even passes the FCC / CE certification must undergo in-country testing and certification. But the probability of getting certified is high in case if the products already hold FCC / CE certification. RF Products that are used inside Australia must have the C-Tick mark. CE declaration is recognized in Australia. The ACMA (Australian Communication and Media Authority) accepts products that are tested for ETSI limits. The product has to be registered with ACMA for obtaining and using the C-Tick mark. SAR, Specific absorption rate, is a measure of radiated RF energy absorbed by a human body tissue. SAR is expressed in watts per kilogram (W/kg) of biological tissue. The ZigBit modules must undergo SAR tests and qualification before commercial release if the device is operating with 20cm distance to the human body. SAR is measured using special lab equipments and environments. The device under test is placed in a phantom shell with tissue and checked for RF field exposure. The phantom is in human body shape and the DUT is positioned in the head part and body part. Probe positioner and device positioner are used to move the respective devices and simulated data is acquired and analyzed. SAR testing requirements on customers base board has to be decided, based on the nature of intended application. Designers can use the ZigBit alone or with additional circuits on the base board. In this case following points need to be taken care. The custom product may contain any of the following circuits 1. High Voltage 2. Switching circuits 9 4.3 Taiwan 4.4 China 4.5 Australia 5 SAR Requirements 6 Appendix 6.1 Appendix A

3. Secondary or another radio part When the above mentioned blocks are bought out items and are already pre-certified individually, the designer is expected to verify the entire product with FCC accredited Lab. The ZigBits FCC ID is still valid but cannot be used as a final products FCC ID because there are additional circuits in the product. But since ZigBits already carry FCC ID and are certified, the likelihood of getting the entire product certified is high, since the rest of circuits in the product are pre-certified too. If circuits listed above are not present in Customers base board and if customers base board is only for carrying the ZigBit ATZB-24-A2 or ATZB-A24-UFL module, then there is no need for re-certification When all or any of the above mentioned blocks are not pre-certified / non-compliant, irrespective of the scenarios mentioned for all of the ZigBits, the designers must certify the entire product and the likelihood of successful certification depends on the circuit design of the extra circuits added apart from the ZigBit. Testing and maintaining reports will be useful in a case when FCC / ETSI conducts audit on the product and asks the product owner for test reports and affiliated documents in a short notice 10 AVR[appn ote nr]
