Zigbit™ Module Overview
2.1
Overview
ZigBit is a low-power, high-sensitivity IEEE 802.15.4/ ZigBee-compliant OEM module. This multi-functional device occupies less than a square inch of space, which is comparable to a typical size of a single
chip. Based on a solid combination of Atmel’s latest MCU Wireless hardware platform [1], the ZigBit
offers superior radio performance, ultra-low power consumption, and exceptional ease of integration.

Zigbit™ Module Overview
ZigBit modules comply with the FCC (Part 15), IC and ETSI (CE) rules applicable to the devices radiating 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 the
Council of 27January 2003 on the restriction of the use of certain hazardous substances in electrical and
electronic equipment” (RoHS). Atmel provides fully compliant product in all regions where the directive is
enforced since July 1, 2006.
ZigBit contains Atmel’s ATmega1281V Microcontroller [1] and AT86RF230 RF Transceiver [2]. The module features 128 Kbytes flash memory and 8 Kbytes RAM.
The ZigBit already contains a complete RF/MCU-related design with all the necessary passive components included. The module can be easily mounted on a simple 2-layer PCB. Compared to a custom
RF/MCU design, 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.
Innovative (patent-pending) dual chip antenna design in ATZB-24-A2 module eliminates the balun and
achieves good performance over 2.4 GHz frequency band.
To jumpstart evaluation and development, Atmel also offers a complete set of evaluation and development tools. The ZigBit Development Kit [6] (ATZB-DK-24) comes with everything you need to create
custom applications featuring ZigBit module.
The kit features MeshBean development boards with an easy-to-access extension connector for attaching 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 hardware interface layer and reference drivers for the all the module interfaces, intuitive development
environment 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 the
standard, 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, 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.

Differential RF Input/Output
1. The UART_TXD pin is intended for input (i.e. its designation as "TXD" implies some complex system
containing 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 in
details in the ATmega1281V Datasheet [1].
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, [1]).
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:
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 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 providing 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.

9. Using ferrite bead and 1 µF capacitor located closely to the power supply pin is recommended, as
shown below.
10. Pins 44 through 48 are not designed for the ATZB-24-A2 module. Note these pins are used in
ATZB-24-B0, see them in antenna schematics below.

Mounting Information
The below diagrams show the PCB layout recommended for ZigBit 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 the pins thus minimizing inductance
and preventing both mismatch and losses.

match, 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.

Figure 3-12. PCB Layout with Dual Chip Antenna Module recommended for ATZB-24-A2
Normally, chip antennas are more tolerant of the board or enclosure materials in ZigBit's neighborhood
as 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. 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 must be
placed 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, the
antenna performance may only be guaranteed for the particular board type and thickness.
