2. ZigBee interface
2.1.
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.

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.

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

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.

FCC Compliance Requirements with KDB996369
- 24 -
i. “Module is limited to OEM installation ONLY “
ii. “OEM integrators is responsible for ensuring that the end-user has no manual
instructions to remove or install module”
iii. “FCC RF Exposure requirements: Module is limited to installation in mobile or fixed
applications, according to Part 2.1091(b). Separate FCC approval is required for all other
operating configurations, including portable configurations with respect to Part 2.1093 and
different antenna configurations.”
iv. “If (1) the module’s FCC ID is not visible when installed in the host, or (2) if the host is
marketed so that end users do not have straightforward commonly used methods for access
to remove the module so that the FCC ID of the module is visible; then an additional
permanent label referring to the enclosed module: “Contains Transmitter Module FCC ID:
2AE73-CRC2602” or “Contains FCC ID: 2AE73-CRC2602” must be used. The host OEM user
manual must also contain clear instructions on how end users can find and/or access the
module and the FCC ID.”
v. “A host product is required to comply with all applicable FCC equipment authorizations
regulations, requirements and equipment functions not associated with the transmitter module
portion. For example, compliance must be demonstrated to regulations for other transmitter
components within the host product; to requirements for unintentional radiators (Part 15B),
such as digital devices, computer peripherals, radio receivers, etc.; and to additional
authorization requirements for the non-transmitter functions on the transmitter module (i.e.,
Verification, or Declaration of Conformity) (e.g., Bluetooth and WiFi transmitter modules may
also contain digital logic functions) as appropriate.
vi. To ensure compliance with all non-transmitter functions the host manufacturer is
responsible for ensuring compliance with the module(s) installed and is fully operational. For
example, if a host was previously authorized as an unintentional radiator under the
Declaration of Conformity procedure without a transmitter certified module and a module is
added, the host manufacturer is responsible for ensuring that after the module is installed and
operational the host continues to be compliant with the Part 15B unintentional radiator
requirements. Since this may depend on the details of how the module is integrated with the
host, the grantee (the party responsible for the module grant) shall provide guidance to the
host manufacturer for compliance with the Part 15B requirements.”
