SPZB32W1x1.4 Description
1 Description
The SPZB32W1x.4 is a ready-to-use device, compliant with IEEE 802.15.4 and power
amplified RF modules optimized for embedded applications. It requires low data rate
communication and high transmission range capabilities based on the STM32W single chip,
which integrates a 2.4 GHz, IEEE 802.15.4-compliant transceiver together with an ARM
Cortex embedded processor.
The modules are very compact and enable OEMs to easily add wireless capabilities to
electronics 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 networking
capability to the final product.
24 MHz high stability Xtal is available onboard the modules to perform the timing
requirements as per IEEE 802.15.4 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 2.1
to 3.6 V. The voltage supply also determines the I/O ports level allowing an easy interface
with additional peripherals.
An advanced solution integrating PA and LNA in a single package is onboard to ensure
excellent power transmission and receiver sensitivity performances.
To support user defined applications, a number of peripherals such as GPIO, UART, I
ADC and general purpose timers are available and user selectable.

C,
The size and footprint of this series of modules is equivalent to that of the series
SPZB32W1x2.4 to facilitate the evaluation of the different range options on the target
application.
The SPZB32W1x1.4 is based on the STM32W108CB chipset integrating 128 kB of
embedded flash memory and 8 kB of RAM available for data and program storage.
For technical details on the STM32W108CB chipset refer to the related datasheet. For
technical details on the supported stacks refer to the related user guides and application
notes available on the ST website.
