The STM32 Wireless series is the only chip family with built-in wireless capabilities. This series uses ARM Cortex M4 and additional Arm Cortex M0+ as a radio coprocessor or, eventually, a single ARM Cortex M0+ core in low power version.
The STM32 Wireless series features built-in radio modules (sub-gigahertz or 2.4GHz) for IoT protocols such as:
Applications that benefit from the STM32 Wireless series include industrial automation, IoT devices and, particularly, smart homes.
A short review of the MCUs and their features is juxtaposed in table ##REF:stm32hwhp##. Note each row in the table represents a family of devices, and a particular configuration depends on the exact MCU model. Thus, developers, when looking for particular features, should refer to the manufacturer's specification and list of currently available devices [1].
