## 2. Key Features
### 2.1 Microcontroller Core
- **ARM Cortex - M3 Core**: At the heart of the STM32W108CC lies an ARM Cortex - M3 32 - bit RISC core. This core provides a high level of processing power, with a maximum operating frequency of up to 32 MHz. It offers excellent code density and low power consumption, making it ideal for battery - powered applications. The Cortex - M3 core also features a nested vectored interrupt controller (NVIC), which allows for efficient handling of multiple interrupt sources, enabling real - time response to events.
- **Memory Configuration**: The microcontroller comes with a generous amount of on - chip memory. It has 256 KB of flash memory, which can be used to store the application code. Additionally, there is 32 KB of SRAM, providing sufficient space for data storage and manipulation during runtime. This memory configuration allows for the development of complex applications without the need for external memory expansion in most cases.
### 2.2 Wireless Connectivity
- **IEEE 802.15.4 Compliant Radio**: The STM32W108CC integrates an IEEE 802.15.4 compliant radio transceiver. This standard is widely used in low - power, low - data - rate wireless networks, such as ZigBee and Thread. The radio operates in the 2.4 GHz ISM band, which is globally available, enabling seamless communication across different regions. It offers a high - sensitivity receiver with a typical sensitivity of - 97 dBm, ensuring reliable communication over long distances.
- **Advanced RF Features**: The radio transceiver in the STM32W108CC is equipped with advanced features such as automatic gain control (AGC), which adjusts the receiver gain based on the received signal strength, and a crystal oscillator with high accuracy. It also supports frequency hopping spread spectrum (FHSS) and direct sequence spread spectrum (DSSS) modulation techniques, providing enhanced resistance to interference and improving the overall reliability of the wireless link.
### 2.3 Peripherals
- **Analog - to - Digital Converter (ADC)**: The microcontroller features a 12 - bit ADC with up to 16 channels. This ADC can be used to convert analog signals from various sensors, such as temperature sensors, pressure sensors, and light sensors, into digital values for further processing. It has a high sampling rate of up to 1 MSPS, allowing for real - time data acquisition.
- **Universal Serial Bus (USB) Interface**: The STM32W108CC includes a USB 2.0 full - speed interface. This interface can be used for programming the microcontroller, as well as for data transfer between the microcontroller and a host computer. It simplifies the development process and enables easy integration with existing USB - based systems.
- **General - Purpose Input/Output (GPIO) Pins**: There are a sufficient number of GPIO pins available on the STM32W108CC. These pins can be configured as either input or output pins, allowing for easy connection to external devices such as switches, LEDs, and relays. They can also be used for implementing custom communication protocols or for interfacing with
