series introduction
# Introduction to STM32F107RBT6 Product Series
## 1. Overview
The STM32F107RBT6 is a member of the popular STM32F1 series of microcontrollers developed by STMicroelectronics. This series is based on the ARM Cortex - M3 32 - bit RISC core, which combines high performance, low power consumption, and rich peripheral integration, making it suitable for a wide range of applications in the embedded systems field.
## 2. Key Features
### 2.1 Core and Performance
- **ARM Cortex - M3 Core**: The ARM Cortex - M3 core at the heart of the STM32F107RBT6 offers a high - performance processing platform. It has a Harvard architecture with a 3 - stage pipeline, enabling efficient instruction execution. The core can operate at a maximum frequency of 72 MHz, providing sufficient computing power for complex tasks such as real - time control, data processing, and communication protocol handling.
- **Memory Protection Unit (MPU)**: The built - in MPU allows for the protection of different memory regions, enhancing system security and reliability. It can prevent unauthorized access to critical memory areas, which is crucial in applications where data integrity and system stability are of utmost importance.
### 2.2 Memory
- **Flash Memory**: The STM32F107RBT6 is equipped with 128 KB of embedded Flash memory. This non - volatile memory is used to store the program code, allowing the microcontroller to retain its functionality even when the power is turned off. The Flash memory has a high - speed access time, enabling fast code execution.
- **SRAM**: It also features 20 KB of static random - access memory (SRAM). SRAM is used for storing variables, data buffers, and intermediate results during program execution. The relatively large SRAM size provides enough space for handling complex algorithms and data processing tasks.
### 2.3 Peripherals
#### 2.3.1 Communication Peripherals
- **Ethernet MAC**: One of the standout features of the STM32F107RBT6 is its integrated Ethernet Media Access Controller (MAC). This allows the microcontroller to connect to an Ethernet network directly, enabling applications such as network - based monitoring, control, and data transfer. It supports the IEEE 802.3 standard and can operate at speeds of up to 10/100 Mbps.
- **USB 2.0 Full - Speed Interface**: The USB 2.0 full - speed interface provides a convenient way to connect the microcontroller to a host computer or other USB - enabled devices. It can be used for data transfer, device configuration, and power supply in some cases. The USB interface supports both device and host modes, adding flexibility to the system design.
- **UART, SPI, and I2C Interfaces**: Multiple Universal Asynchronous Receiver - Transmitter (UART), Serial Peripheral Interface (SPI), and Inter - Integrated Circuit (I2C) interfaces are available. These interfaces are commonly used for communication with external sensors, actuators, and other microcontrollers. UART is suitable for long - distance serial communication, while SPI and I2C are used for short - distance, high - speed data transfer between integrated circuits.
#### 2.3.2 Timers
- **Multiple Timers**: The microcontroller includes several general - purpose timers and advanced - control timers. General - purpose timers can be used for tasks such as generating PWM signals for motor control, measuring time intervals, and counting external events. Advanced - control timers offer additional features such as complementary PWM outputs, which are useful for driving three - phase motors.
