- 10 - 2. ZigBee interface2.1. The ZigBee protocol The ZigBee Alliance is an association of companies working together to enable reliable, costeffective, low-power, wirelessly networked, monitoring and control products based on an open global standard. The ZigBee Alliance is a rapidly growing, non-profit industry consortium of leading semiconductor manufacturers, technology providers, OEMs and end-users worldwide. Membership is open to all. The ZigBee Alliance, in collaboration with the IEEE, is defining the network, security, and application layers above the IEEE 802.15.4 PHY and MAC layers. This cooperation has resulted in an easy-to-use, standards-based wireless network platform optimized for wireless monitoring and control applications. For more information about the ZigBee Alliance and the ZigBee standard, please consult www.zigbee.org The module is intended for using the ZigBee protocol. However, other proprietary network protocols can also be implemented using the module. The ZigBee stack implementation from TI/Chipcon/Figure 8 Wireless is recommended as it provides seamless integration with the module. However, third party stack implementations can also be used provided they support the TI/Chipcon MAC firmware. 2.2. Debugging interface The modem has a two-wire proprietary debug interface. This interface can also be used for incircuit programming of the device. For debugging the device programmer sends command <DEBUGGING_INSTR> to the icrocontroller. The instructions succeeding the debugging commando are executed by the CPU without updating the program counter. For in circuit programming the same debugging command is used, only the instruction preformed is flash programming with through the flash controller. Supply and ground must also be connected during programming or debugging. Pin Description 21 P2.2, Debug Clock 22 P2.1, Debug Data Pin 21 and 22 can be used as normal digital I/O pins when the module is not in debugging mode.
- 11 - 2.3. Power management The ZigBee protocol allows End Devices to be powered down, while Routers must be powered all the time in order to handle packet routing. Battery operated devices should be End Devices in order to reduce the power consumption to a minimum. The modem can be set in several sleep modes using the features of the MCU and turning off the RF transceiver. Sleep modes enable the application to shut down unused segments in the MCU, thereby saving power. The MCU provides various sleep modes allowing the user to tailor the power consumption to the application’s requirements. To enter any of the 3 sleep modes (power modes 1-3) available in the modem, the appropriate registers in CC2530 must be set. See datasheet for CC2530 for details. The different power modes available are: Power mode 1 – Digital regulator on; 16-MHz RCOSC and 32-MHz crystal oscillator off; 32.768-kHz XOSC, POR, BOD and sleep timer active; RAM and register retention. Power mode 2 – Digital regulator off; 16-MHz RCOSC and 32-MHz crystal oscillator off; 1 2 μA 32.768-kHz XOSC, POR, and sleep timer active; RAM and register retention. Power mode 3 – Digital regulator off; no clocks; POR active; RAM and register retention. 2.4. RF frequency, output power levels and data rates The following table shows the RF channels as defined by the IEEE 802.15.4 standard. RF channel Frequency 11 2405MHz 12 2410MHz 13 2415MHz 14 2420MHz 15 2425MHz 16 2430MHz 17 2435MHz 18 2440MHz 19 2445MHz 20 2450MHz 21 2455MHz 22 2460MHz 23 2465MHz 24 2470MHz 25 2475MHz 26 2480MHz For proprietary solutions (non-IEEE 802.15.4), the RF transceiver can be programmed in steps of 1 MHz. The output power level can be configured from the firmware in the range about -22 to 4.5 dBm.
- 12 - The RF transceiver uses direct sequence spread spectrum (DSSS) with 2 Mchip/s chip rate, giving a raw data rate of 250Kbit/s. The modulation format is Offset – Quadrature Phase Shift Keying (O-QPSK). The DSSS makes the communication link robust in noisy environments when sharing the same frequency band with other applications. The use of RF frequencies and maximum allowed RF power is limited by national regulations. The modem is complying with the applicable regulations for the world wide 2.45 GHz ISM band. Specifically it complies with the European Union R&TTE directive meeting EN 300 328 and EN300 440 class 2. It also meets the FCC CFR47 Part15 regulations for use in the US and the ARIB T-66 for use in Japan. 2.5. Antenna and range considerations This modem is a very compact solution containing all the critical RF parts within the modem. However, a somewhat better range can be achieved using an external antenna. Range testing using the external antenna shows these typical distances: - Compact size with a ceramic antenna working as a quarter-wave resonant antenna - Good performance with ¼ wave monopole antenna on ground plane - High performance with with 5/8 wave dipole antenna Due to the dielectric ceramic material the antenna is shorter than a normal quarter wave antenna (in air), still providing high radiation efficiency (typical 1 dBi). The antenna is matched for use in the 2.45 GHz band. The radiating part of the antenna is the white ceramic component located outside the shield can. The radiation pattern from the antenna is similar to the donut-shaped radiation from a quarter wave antenna. That is, the maximum radiation is in the plane normal to the length axis of the antenna. For best possible omni-directional radiation the module should be oriented so that the antenna is vertical. To achieve the very best range the transmitting and receiving antenna should be oriented the same way, ensuring the same polarity at both devices. However, indoors reflections of the radio waves in metallic structures tend to spread the polarisation, so even if same orientation is not possible, communication will still take place, but the range is somewhat shorter, typically by 20%. The antenna should be kept away (> 10mm) from metallic or other conductive and dielectric materials, and should never be used inside a metallic enclosure. Compared to lower frequencies, operation at 2.45 GHz is more limited to LOS. Reflections from walls and other objects may give multi-path fading resulting in dead-zones. The ZigBee mesh network topology is used to overcome this fading as it allows for alternative routing paths. The mesh network is therefore highly recommended for increased reliability and extended coverage throughout buildings. In applications where the module must be placed in a metallic enclosure, an external
- 13 - antenna must be used. The RF available at a module pin must be fed to external antenna. The RF input/output is matched to 50 Ohm. If the antenna or antenna connector is placed away from the module at the motherboard, the track between the RF pin and the connector should be a 50 Ohm transmission line. On a two layer board made of FR4 the width of a microstrip transmission line should be 1.8 times the thickness of the board, assuming a dielectric constant of 4.8. The line should be run at the top of the board, and the bottom side should be a ground plane. Example: For a 1.6 mm thick FR4 board, the width of the trace on the top side should be 1.8 x 1.6 mm = 2.88 mm. The simplest antenna to use is the quarter wave whip antenna. A quarter wave whip antenna above a ground plane yields 37 Ohm impedance and a matching circuit for 50 Ohm are usually not required. A PCB antenna can be made as a copper track where the ground plane is removed on the back side. The rest of the PCB board should have a ground plane as large as possible, preferably as large (in one dimension) as the antenna itself, to make it act as a counterweight to the antenna. A quarter wavelength antenna on a PCB must be shorter than the wire antenna due to the influence of the dielectric material of the PCB. The length reduction depends on the PCB thickness and material, as well as how close to the edge of the board the antenna is placed. Typical reduction is to 75-90 % but must be found empirically. The length of a quarter-wave antenna is given in the table below. Frequency{MHz} Length of whip antenna[cm] Length of PCB track[cm] 2450 2.9 2.25 ~ 2.7 If, for space reasons, the track is made even shorter than the resonating quarter of a wavelength, the antenna should be matched to 50 ohms using a series inductor and a shunt capacitor.
