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.

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 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

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.
