DESCRIPTION 
SPZB32W1A2.1 / SPZB32W1C2.1 are ready-to-use  
ZigBee ® modules optimized for embedded applications 
requiring short range performances. These  high-
performance, very compact modules enable OEMs to easily 
add  short range reach wireless capability to electronic 
devices by optimizing time-to-market, cost and size of their 
target applications. 
The modules are based on STM32W single chip ZigBee® 
solution which integrates a 2.4GHz, IEEE 802.15.4-
compliant transceiver together with an embedded 
processor. 
24 MHz high stability Xtal is available aboard the modules 
to perform the timing requirements as per ZigBee ® 
specifications; additionally a 32.768kHz Xtal is provided 
for low power operation. 
A single supply voltage is requested to power the modules. 
An innovative 2.5 GHz RF design and the relevant internal 
RF Amplifier aboard ensure the optimal exploitation of the 
link budget, an excellent sensitivity and still low power 
consumption for battery powered operation.  
The voltage supply also determines the I/O ports level 
allowing an easy interface with additional peripherals.  
A 128kB of embedded flash memory and 8kB of 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. 
Modules are available with two different antenna options:  
• SPZB32W1A2.1    with integrated ceramic 
antenna aboard 
• SPZB32W1C2.1    with  UFL RF connector for 
the connection of  an  external  antenna.

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 SPZB32W1x2.1 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.

A.1 - LABEL INSTRUCTION 
INSTRUCTION MANUAL FOR FCC ID LABELING 
Module type  : ZigBee®  module       SPZB32W1A2.1 / SPZB32W1C2.1 
FCC-ID : S9NZB32C2 
This intends to inform you how to specify the FCC ID of our  ZigBee module SPZB32W1A2.1  / 
SPZB32W1C2.1   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: S9NZB32C2 or “Contains 
FCC ID: S9NZB32C2 , any similar wording that expressed the same meaning may be use. 
It shows an example below 
 Contains FCC ID: S9NZB32C2

                                                                                                                                                                                                                        11/12 
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.  
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: 1.90 mW  (2.77 dBm ) 
•           Maximum antenna gain:      2.2  dBi       (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.
