series introduction
# Introduction to the STM32F103R6T6 Product Series
## 1. Overview
The STM32F103R6T6 belongs to the STM32F103 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 features. The STM32F103R6T6 is specifically designed to meet the requirements of a wide range of embedded applications, offering a cost - effective solution for developers.
## 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 can execute instructions at a maximum frequency of 72 MHz, enabling fast data processing and efficient code execution.
- **Instruction Set**: It supports the Thumb - 2 instruction set, which combines the code density of the Thumb instruction set with the performance of the ARM instruction set. This allows for more compact code size while maintaining high performance.
### 2.2 Memory
- **Flash Memory**: The STM32F103R6T6 is equipped with 32 KB of embedded flash memory. Flash memory is non - volatile, which means it can retain data even when the power is turned off. This is used to store the program code of the microcontroller, allowing for easy reprogramming and updates.
- **SRAM**: It has 6 KB of static random - access memory (SRAM). SRAM is used for storing temporary data during program execution, such as variables, buffers, and stack space.
### 2.3 Peripherals
#### 2.3.1 GPIO (General - Purpose Input/Output)
- The microcontroller has a total of 37 general - purpose I/O pins. These pins can be configured as either input or output, allowing for easy connection to external devices such as sensors, actuators, and displays. They can also be used for various communication protocols and control signals.
#### 2.3.2 Timers
- **Advanced - control Timers**: It includes 1 advanced - control timer with a 16 - bit counter. This timer can be used for applications such as motor control, generating PWM (Pulse - Width Modulation) signals for controlling the speed of motors or the brightness of LEDs.
- **General - purpose Timers**: There are 3 general - purpose timers, each with a 16 - bit counter. These timers can be used for tasks such as measuring time intervals, generating periodic interrupts, and implementing simple control algorithms.
#### 2.3.3 Communication Interfaces
- **USART (Universal Synchronous/Asynchronous Receiver/Transmitter)**: It has 2 USART interfaces, which support both synchronous and asynchronous communication. USART is commonly used for serial communication with other devices, such as computers, sensors, and modems.
- **SPI (Serial Peripheral Interface)**: There are 2 SPI interfaces, which provide a high - speed serial communication protocol. SPI is often used for communicating with external devices such as flash memories, sensors, and displays.
- **I²C (Inter - Integrated Circuit)**: It includes 1 I²C interface, which is a multi - master, multi - slave serial communication protocol. I²C is widely used for connecting low - speed devices such as sensors, EEPROMs, and real - time clocks.
#### 2.3.4 ADC (Analog - to - Digital Converter)
