SPZB32W1A2.1 and SPZB32W1C2.1 are ready-to-use ZigBee® modules optimized for embedded applications that require low data rate communications. The modules are very compact and enable OEMs to easily add wireless capabilities to electronic devices by optimizing time-to-market, cost, size, and consumption of their target applications. No RF experience or expertise is required to add this powerful wireless networking capability to the final product.
The modules are based on the ST STM32W108CB single chip which integrates a 2.4 GHz, IEEE 802.15.4-compliant transceiver together with an ARM® Cortex-M3 embedded processor.
24 MHz high stability Xtal is available aboard the modules to perform the timing requirements as per ZigBee specifications; additionally, a 32.768 kHz Xtal is also provided onboard for low power operation.
A single supply voltage is requested to power the modules. The supply is in the range of 2.8 to 3.6 V.
An innovative 2.5 GHz RF design and the relevant internal RF amplifier onboard ensure the optimal exploitation of the link budget, an excellent sensitivity and low power consumption for battery powered operation.
The voltage supply also determines the I/O port level, allowing an easy interface with additional peripherals.
To support user defined applications, a number of peripherals such as GPIO, UART, I2C,ADC, and general purpose timers are available through the 24 configurable general purpose I/O lines.
The modules can run the ZigBee PRO EmberZNet firmaware packages (ZigBee PRO stack) which are accessible on the ST website.
Modules are available with two different antenna options:
● SPZB32W1A2.1, with an onboard integrated ceramic antenna
● SPZB32W1C2.1, with UFL RF connector for the connection of an external antenna.

The STEVAL-IDZ3xxV1 is a demonstration kit from the SPZB32W1x2.x series of 802.15.4/ZigBee® RF modules based on the STM32W108CB microcontroller that integrates a 32-bit ARM® Cortex™ M3 microprocessor and a 2.4 GHz, IEEE 802.15.4 radio.
Accordingly, with the loaded protocol stack and application SW, the STM32W108CB microcontroller is suitable for different types of wireless network scenarios.Each STEVAL-IDZ3xxV1 kit enables the user to test the RF module performances, the features of the protocol libraries defined for the microcontroller, and to prototype the target 802.15.4/ZigBee application. The kit includes a development board and a software library that can be integrated into the structure of the packages available from the ST website for the use of ZigBee PRO, Zigbee RF4CE and simplified MAC on the STM32W108CB microcontroller. The STEVAL-IDZ3xxV HW integrates an RF module belonging to the SPZB32W1x2.x series together with an extended number of external connectors that allow the integration of peripherals as requested by the target application.
The STEVAL-IDZ3xxV1 kit can be used for the following purposes.
■ Demonstration: ZigBee PRO. By using the sensor/sink application example integrated in the kit and two development boards, the user can easily set up a demo showing a few of the basic features of the ZigBee protocol stack.
■ Development: by using external equipment consisting of a development environment for the STM32W, the kit can be used to prototype and debug a target application.
This document describes the hardware and software components of the STEVAL-IDZ3xxV1 and provides instructions for setting up the hardware and loading and running the application examples. This document is not meant to be a ZigBee tutorial and assumes that the user is familiar with IAR development tools and the basic features of the STM32W108CB microprocessor.
