1. Introduction 1.1 Summary ZigBit® is an ultra-compact, low-power, high-sensitivity 2.4GHz IEEE 802.15.4/ZigBee® OEM module based on the innovative mixed-signal hardware platform from Atmel. It is designed for wireless sensing, control and data acquisition applications. ZigBit modules eliminate the need for costly and time-consuming RF development, and shorten time-to- market for a wide range of wireless applications. Two different versions of 2.4GHz ZigBit modules are available: the Atmel ATZB-24-B0 module with balanced RF port for applications where the benefits of PCB or external antenna can be utilized and the Atmel ATZB-24-A2 module with dual chip antenna satisfying the needs of applications that require integrated, small-footprint antenna design. 1.2 Applications ZigBit module is compatible with robust IEEE 802.15.4/ZigBee stack that supports a self-healing, self-organizing mesh network, while optimizing network traffic and minimizing power consumption. Atmel offers two stack configurations: BitCloud and SerialNet. BitCloud is a ZigBee PRO certified software development platform supporting reliable, scalable, and secure wireless applications running on the Atmel ZigBit modules. SerialNet allows programming of the module via serial AT-command interface. The applications include, but are not limited to: • Building automation and monitoring • Lighting controls • Wireless smoke and CO-detectors • Structural integrity monitoring • HVAC monitoring and control • Inventory management • Environmental monitoring • Security • Water metering • Industrial monitoring • Machinery condition and performance monitoring • Monitoring of plant system parameters such as temperature, pressure, flow, tank level, humidity, vibration, etc. • Automated Meter Reading (AMR) ATZB-24-A2/B0 [ZigBit 2.4GHz Wireless Modules] 3 8226C−AVR−07/2013

2. ZigBit Module Overview 2.1 Overview ZigBit is a low-power, high-sensitivity IEEE 802.15.4/ ZigBee-compliant OEM module. This multifunctional 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 the latest MCU Wireless hardware platform from Atmel, the ZigBit offers superior radio performance, ultra-low power consumption, and exceptional ease of integration. Figure 2-1. Atmel ATZB-24-B0 Block Diagram. V (1.8 – 3.6) CC IRQ UART AT86RF230 USART/SPI ATmega1281 RF RF I/O I2C transceiver JTAG ANALOG GPIO SPI Bus . Figure 2-2. Atmel ATZB-24-A2 Block Diagram. V (1.8 – 3.6) CC IRQ UART AT86RF230 USART/SPI ATmega1281 RF Chip I2C antenna transceiver JTAG ANALOG GPIO SPI Bus ZigBit modules comply with the FCC (Part 15), IC and ETSI (CE) rules applicable to the devices radiating in an uncontrolled environment. For further details, see Chapter 4. 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. ATZB-24-A2/B0 [ZigBit 2.4GHz Wireless Modules] 6 8226C−AVR−07/2013

The ZigBit contains the Atmel ATmega1281V Microcontroller [1] and the Atmel AT86RF230 RF Transceiver [2]. The module features 128KB Flash memory and 8KB 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 dual chip antenna design in ATZB-24-A2 module eliminates the balun and achieves good performance over 2.4GHz frequency band. All ZigBits are preloaded with a Bootloader when they are sold as Modules, either in Single units or T&R. Depending on end-user design requirements, a ZigBit module 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.

3. Specification 3.1 Electrical Characteristics 3.1.1 Absolute Maximum Ratings Table 3-1. Absolute Maximum Ratings (1)(2) Parameter Minimum Maximum Voltage on any pin, except RESET with respect to ground -0.5V V + 5V CC DC current per I/O pin 40mA DC current DVCC and DGND pins 200mA Input RF level +10dBm Notes: 1. Absolute Maximum Ratings are the values beyond which damage to the device may occur. Under no circumstances must the absolute maximum ratings given in this table be violated. Stresses beyond those 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 those indicated in the operational sections of this specification, is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 2. Attention! ZigBit is an ESD-sensitive device. Precaution should be taken when handling the device in order to prevent permanent damage. 3.1.2 Test Conditions Table 3-2. Test Conditions (unless otherwise stated), V = 3V, T = 25°C. cc amb Parameter Range Unit Supply voltage, V (2) 1.8 to 3.6 V CC Current consumption: RX mode 21.8 mA Current consumption: TX mode (1) 20.8 mA Current consumption: Radio is turned off, MCU is active 50% of the time (1) 3.5 mA Current consumption: Power-save mode (1) 6 µA Notes: 1. The parameters are measured under the following conditions: a) BitCloud Software is running at 8MHz clock rate, DTR line management is turned off. b) All interfaces are set to the default state (see Pin Assignment Table). c) Output TX power is 0dBm d) JTAG is not connected. 2. Supply voltage below 2.7V requires the MCU to be operating at 2MHz speed. Current consumption actually depends on multiple factors, including but not limited to, the board design and materials, BitCloud settings, network activity, EEPROM read/write operations. It also depends on MCU load and/or peripherals used by an application. ATZB-24-A2/B0 [ZigBit 2.4GHz Wireless Modules] 8 8226C−AVR−07/2013

The UART_TXD pin is intended for input (that is, its designation as "TXD" implies some complex system containing ZigBit as its RF terminal unit), while the 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 Atmel 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 32.768kHz 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 a mechanism for power management of the host processor. If this function is necessary, a connection of this pin to an external pull-down resistor is recommended to prevent the undesirable transients during the module reset process. 9. Using ferrite bead and 1µF capacitor located closely to the power supply pin is recommended, as shown below: ATZB-24-A2/B0 [ZigBit 2.4GHz Wireless Modules] 13 8226C−AVR−07/2013

10. Pins 44 through 48 are not designed for the Atmel ATZB-24-A2 module. Note these pins are used in Atmel ATZB- 24-B0, see them in antenna schematics below: Note: TXD, RXD of UART are crossed inside ZigBit Module. So external UART devices connecting to ZigBit Module should just follow straight connection for UART. UART_TXD_external_device <-> UART_TXD UART_RXD_external_device <-> UART_RXD 11. In SPI mode, USART0_EXTCLK is output. In USART mode, this pin can be configured as either input or output pin. 3.4 Mounting Information Figure 3-5 and Figure 3-6 show 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.

These antenna reference designs are recommended for successful design-in. ATZB-24-A2/B0 [ZigBit 2.4GHz Wireless Modules] 15 8226C−AVR−07/2013

Figure 3-7. PCB layout: Symmetry Dipole Antenna Recommended for Atmel ATZB-24-B0. The 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 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. ATZB-24-A2/B0 [ZigBit 2.4GHz Wireless Modules] 16 8226C−AVR−07/2013

3.5.2 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 • 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 RF frequency band ATZB-24-A2/B0 [ZigBit 2.4GHz Wireless Modules] 17 8226C−AVR−07/2013

3.8 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 compliance of suitable Ingress Protection standards. ATZB-24-A2/B0 [ZigBit 2.4GHz Wireless Modules] 20 8226C−AVR−07/2013
