Description
SPZB250 is a low power consumption ZigBee
module based on SN250 ZigBee Network
Processor which integrates a 2.4GHz, IEEE
802.15.4-compliant transceiver as well as IEEE
802.15.4 PHY and MAC. It enables OEMs to
easily add wireless networking capability to any
electronic device. Such a module is a very
comprehensive solution to build sensors with
meshing and self healing capability as required in
a WSN scenario.
24 MHz high stability Xtal is available aboard the
module to perform the timing requirements as per
ZigBee specifications. An additional 32.768 kHz
Xtal is provided for low power operation.
A single supply voltage is requested to power the
module. An integrated 2.5 GHz specific Murata
antenna is aboard. The voltage supply also
determines the I/O ports level allowing an easy
interface with the host system.
128k flash and 5kbytes of static RAM are
available for data and program storage.
To support user defined applications, a number of
peripherals such as GPIO,UART,I2C, ADC and
general purpose timers are available and user
selectable.
The deep sleep mode with power consumption of
less than 1 uA allows applications where the
battery life is a key point.

FCC statement SPZB250
Appendix A FCC statement
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired
operation.
Note: This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by one or more of the following measures:
● Reorient or relocate the receiving antenna
● Increase the separation between the equipment and receiver
● Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected
Consult the dealer or an experienced radio/TV technician for help.
Antenna
Our module type SPZB250 is for OEM integrations only. The end-user product will be
professionally installed in such a manner that only the authorized antennas are used.
Caution
Any changes or modifications not expressed approved by the part responsible for
compliance could cause the module to cease to comply with FCC rules part 15, and thus
void the user’s authority to operate the equipment.

SPZB250 FCC statement
A.1 Label instruction
Instruction manual for FCC ID labeling
Module type: ZigBee module SPZB250
FCC-ID: S9NZB250A
This intends to inform you how to specify the FCC ID of our ZigBee module SPZB250 on
your final product.
Based on the Public Notice from FCC, the product into which our transmitter module is
installed must display a label referring to the enclosed module.
The label should use wording such as “Contains Transmitter module FCC ID: S9NZB250A
or “Contains FCC ID: S9NZB250A , any similar wording that expressed the same meaning
may be use.
It shows an example below
Contains FCC ID: S9NZB250A
A.2 Special requirement for Modular application
The following requirements are fulfilled:
1. The modular transmitter must have its own RF shielding:
The RF module used on the board fulfils the emission requirements of the FCC rules
without additional shielding.
2. The modular transmitter must have buffered modulation/data inputs:
The module has a memory management unit inside of the IC. The processor
interfacing with the external application by means general purpose I/O ( GPIO) , Uart,
SPI. The processor interfaces also the RF part of the module exchanging data and
command with it. Inside the processor a flash memory is available to download the
customer application and the ZigBee profiles.
3. The modular transmitter must have its own power supply regulation:
The IC contains an own voltage regulation. In case of changes in the supply voltage
VCC (for example caused by temperature changes or other effects), the internal
voltage will be stabilized.
4. The modular transmitter must comply with the antenna requirements of Section 15.203
and 15.204:
The RF module is for OEM (Original Equipment Manufacturer) integration only. The
end-user product will be professionally installed in such a manner that only the
authorized antenna is used.
5. The modular transmitter must be tested in a stand-alone configuration:
The RF module was tested in a stand-alone configuration.
6. The modular transmitter must be labelled with its own FCC ID number:
The RF module will be labelled with its own FCC ID number. When the module is
installed inside the end-product, the label is not visible. The OEM manufacturer is
instructed how to apply the exterior label.
13/16
FCC statement SPZB250
7. The modular transmitter must comply with any specific rule or operating requirements
applicable to the transmitter and the manufacturer must provide adequate instructions
along with the module to explain any such requirements:
The EUT is compliant with all applicable FCC rules. Detail instructions are given in the
product Users Guide.
8. The modular transmitter must comply with any applicable RF exposure requirements.
● Maximum measured power output: 3,08 mW
● Maximum antenna gain: 0,6 dBi = numeric gain 1,148 (see also FCC test report)
Maximum permissible exposure defined in 47 CFR 1.1310: 1 mW/cm².
The RF module operates at low power level so it does not exceed the Commission’s RF
exposure guidelines limits; furthermore, Spread spectrum transmitters operate according to
the Section 15.247 are categorically excluded from routine environmental evaluation.
