## 2. Key Features
### 2.1 Core and Performance
- **ARM Cortex - M3 Core**: The ARM Cortex - M3 core provides a high - performance processing platform with a Harvard architecture and a 3 - stage pipeline. It offers a maximum operating frequency of up to 72 MHz, enabling fast execution of instructions and efficient data processing.
- **High - Speed Processing**: The core's advanced architecture allows for efficient handling of complex algorithms, making it suitable for applications such as motor control, industrial automation, and consumer electronics.
- **Memory Protection Unit (MPU)**: The MPU provides a hardware - based memory protection mechanism, which enhances the security and reliability of the system by preventing unauthorized access to critical memory regions.
### 2.2 Memory
- **Flash Memory**: The STM32F103TB is equipped with 128 KB of embedded Flash memory. This non - volatile memory is used to store the program code, allowing for easy reprogramming and updates. The Flash memory has a high - speed access time, which ensures fast code execution.
- **SRAM**: It also features 20 KB of static random - access memory (SRAM). The SRAM is used for storing variables, data buffers, and stack space during program execution. The large SRAM capacity enables the implementation of complex algorithms and data - intensive applications.
### 2.3 Peripherals
#### 2.3.1 Communication Interfaces
- **USART (Universal Synchronous/Asynchronous Receiver/Transmitter)**: Multiple USART interfaces are available, which support both synchronous and asynchronous communication modes. They are commonly used for serial communication with other devices such as sensors, displays, and modems.
- **SPI (Serial Peripheral Interface)**: The SPI interface provides a high - speed serial communication protocol, which is suitable for communicating with external devices such as flash memories, ADCs, and DACs. It supports full - duplex communication and can operate at high clock frequencies.
- **I2C (Inter - Integrated Circuit)**: The I2C interface is a widely used serial communication protocol for connecting low - speed devices such as sensors, EEPROMs, and real - time clocks. It uses a two - wire bus structure, which simplifies the hardware design.
#### 2.3.2 Timers
- **General - Purpose Timers**: The STM32F103TB includes several general - purpose timers, which can be used for a variety of applications such as pulse width modulation (PWM) generation, input capture, and output compare. These timers are highly configurable and can be used to control motors, generate waveforms, and measure time intervals.
- **Advanced - Control Timers**: There are also advanced - control timers available, which are specifically designed for motor control applications. They offer features such as complementary PWM outputs, dead - time insertion, and break input functionality.
#### 2.3.3 Analog - to - Digital Converter (ADC)
- **12 - bit ADC**: The device is equipped with a 12 - bit ADC, which can convert analog signals into digital values with high precision. The ADC has
