ZigBit™ 2.4 GHz Wireless Modules 2-58226C–MCU Wireless–09/10Section 2Zigbit™ Module Overview2.1 OverviewZigBit is a low-power, high-sensitivity IEEE 802.15.4/ ZigBee-compliant OEM module. This multi-func-tional device occupies less than a square inch of space, which is comparable to a typical size of a singlechip. Based on a solid combination of Atmel’s latest MCU Wireless hardware platform [1], the ZigBitoffers superior radio performance, ultra-low power consumption, and exceptional ease of integration.Figure 2-1.

Zigbit™ Module OverviewZigBit™ 2.4 GHz Wireless Modules 2-68226C–MCU Wireless–09/10ZigBit modules comply with the FCC (Part 15), IC and ETSI (CE) rules applicable to the devices radiat-ing in uncontrolled environment. For details, see “Agency Certifications” on page 4-22.ZigBit fully satisfies the requirements of the “Directive 2002/95/EC of the European Parliament and theCouncil of 27January 2003 on the restriction of the use of certain hazardous substances in electrical andelectronic equipment” (RoHS). Atmel provides fully compliant product in all regions where the directive isenforced since July 1, 2006.ZigBit contains Atmel’s ATmega1281V Microcontroller [1] and AT86RF230 RF Transceiver [2]. The mod-ule features 128 Kbytes flash memory and 8 Kbytes RAM.The ZigBit already contains a complete RF/MCU-related design with all the necessary passive compo-nents included. The module can be easily mounted on a simple 2-layer PCB. Compared to a customRF/MCU design, a module-based solution offers considerable savings in development time and NREcost per unit during the design, prototyping, and mass production phases of product development.Innovative (patent-pending) dual chip antenna design in ATZB-24-A2 module eliminates the balun andachieves good performance over 2.4 GHz frequency band.To jumpstart evaluation and development, Atmel also offers a complete set of evaluation and develop-ment tools. The ZigBit Development Kit [6] (ATZB-DK-24) comes with everything you need to createcustom applications featuring ZigBit 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 anddebugging.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 developmentenvironment from Atmel, and comprehensive set of application notes and product documentation.ZigBit 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 control [3],[4], [5] and it provides an augmented set of APIs which, while maintaining 100% compliance with thestandard, offer extended functionality designed with developer's convenience and ease-of-use in mind.Depending on end-user design requirements, ZigBit can operate as a self-contained sensor node, whereit would function as a single MCU, or it can be paired with a host processor driving the module over aserial interface. In the former case, a user application may be used with the BitCloud software allowingcustomization of embedded applications through BitCloud’s C API.In the latter case, the host processor controls data transmission and manages module peripherals via anextensive set of SerialNet AT commands. Thus, no firmware customization is required for a successfulmodule design-in. Additionally, third-party sensors can be connected directly to the module, thusexpanding the existing set of peripheral interfaces.

Absolute Maximum Ratings are the values beyond which damage to the device may occur. Under nocircumstances must the absolute maximum ratings given in this table be violated. Stresses beyondthose listed under "Absolute Maximum Ratings" may cause permanent damage to the device.This is a stress rating only. Functional operation of the device at these or other conditions, beyond thoseindicated in the operational sections of this specification, is not implied. Exposure to absolute maximumrating conditions for extended periods may affect device reliability.2. Attention! ZigBit is an ESD-sensitive device. Precaution should be taken when handling the device inorder to prevent permanent damage.3.1.2 Test Conditions Notes: 1.

SpecificationsZigBit™ 2.4 GHz Wireless Modules 3-138226C–MCU Wireless–09/10Notes: 1. The UART_TXD pin is intended for input (i.e. its designation as "TXD" implies some complex systemcontaining ZigBit 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 indetails in the ATmega1281V Datasheet [1].3. GPIO pins can be programmed either for output, or for input with/without pull-up resistors. Output pindrivers are strong enough to drive LED displays directly (refer to figures on pages 387-388, [1]).4. All digital pins are provided with protection diodes to D_VCC and DGND5. It is strongly recommended to avoid assigning an alternate function for OSC32K_OUT pin because it isused by BitCloud. However, this signal can be used if another peripheral or host processor requires32.768 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 andflash 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:GPIO0, 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 requireschanging 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 ofthis pin to external pull-down resistor is recommended to prevent the undesirable transients duringmodule reset process.35 AGND Analog ground36 GPIO_1WR 1-wire interface(2)(3)(4)(7) I/O37 UART_DTR DTR input (Data Terminal Ready) for UART.

Neither via-holes nor wiresare allowed on the PCB upper layer in area occupied by the module. As a critical requirement, RF_GNDpins should be grounded via several holes to be located right next to the pins thus minimizing inductanceand preventing both mismatch and losses.Figure 3-5.

PCB Layout: Symmetric Dipole Antenna recommended for ATZB-24-B0The symmetric dipole antenna above has been tuned for the particular design. The 'cut-and-paste'approach would not guarantee optimal performance because of multiple factors affecting proper antenna
SpecificationsZigBit™ 2.4 GHz Wireless Modules 3-178226C–MCU Wireless–09/10match, hence, affecting the 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.3.5.1 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 module should not be placed next to consumer electronics which might interfere with ZigBit's RF frequency band.

SpecificationsZigBit™ 2.4 GHz Wireless Modules 3-218226C–MCU Wireless–09/10Figure 3-12. PCB Layout with Dual Chip Antenna Module recommended for ATZB-24-A2Normally, chip antennas are more tolerant of the board or enclosure materials in ZigBit's neighborhoodas well. However, general recommendations given above for the PCB antenna design still apply.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 beplaced around the board's edges as shown.Since the design of dual chip antenna is intended for installation on FR-4 board 1.6 mm thick, theantenna performance may only be guaranteed for the particular board type and thickness.
