series introduction

# Introduction to the STM32F100C4T6A Product Series

## 1. Overview
The STM32F100C4T6A belongs to the STM32F100 value line microcontroller series developed by STMicroelectronics. These microcontrollers are designed to offer a cost - effective solution for a wide range of embedded applications while still providing a good balance of performance, features, and power consumption.

## 2. Core and Architecture
### ARM Cortex - M3 Core
- The STM32F100C4T6A is built around the ARM Cortex - M3 32 - bit RISC core. This core is known for its high performance and low power consumption. It has a Harvard architecture with separate instruction and data buses, which allows for concurrent access to instructions and data, thereby improving the overall processing speed.
- The Cortex - M3 core also features a nested vectored interrupt controller (NVIC), which can handle a large number of interrupt sources with low latency. This is crucial for real - time applications where quick response to external events is required.

### Memory Architecture
- **Flash Memory**: It is equipped with 16 KB of embedded flash memory. Flash memory is non - volatile, which means that the program code stored in it is retained even when the power is turned off. This allows the microcontroller to boot up and execute the stored program immediately after power - on.
- **SRAM**: The device has 4 KB of static random - access memory (SRAM). SRAM is used for storing variables, data buffers, and the stack during program execution. It provides fast access times, enabling the microcontroller to quickly read and write data, which is essential for efficient program operation.

## 3. Peripherals
### General - Purpose Input/Output (GPIO)
- The STM32F100C4T6A has a set of general - purpose input/output pins. These pins can be configured as either inputs or outputs, allowing the microcontroller to interface with external devices such as sensors, actuators, and other digital components.
- GPIO pins can be used for a variety of functions, including reading digital sensor values, controlling LEDs, and communicating with other microcontrollers or devices using simple digital protocols.

### Timers
- **Basic Timers**: There are basic timers available on the microcontroller. These timers can be used for simple time - based tasks such as generating periodic interrupts, measuring time intervals, or controlling the speed of motors in basic applications.
- **Advanced Timers**: The advanced timers offer more complex functionality, such as generating pulse - width modulation (PWM) signals. PWM signals are widely used in applications like motor control, LED dimming, and power management, where the duty cycle of the signal can be adjusted to control the output power or speed.

### Communication Interfaces
- **Universal Asynchronous Receiver/Transmitter (UART)**: The UART interface allows the microcontroller to communicate with other devices using the asynchronous serial communication protocol. It is commonly used for communication with sensors, displays, and other microcontrollers over a serial link.
- **Serial Peripheral Interface (SPI)**: SPI is a synchronous serial communication protocol that provides high - speed data transfer between the microcontroller and external devices. It is often used for communicating with memory chips, sensors, and other high - speed peripherals.
- **Inter - Integrated Circuit (I2C)**: The I2C interface is a multi - master, multi - slave serial communication protocol. It is widely used for connecting low - speed devices such as sensors, EEPROMs, and other integrated circuits on a single bus, reducing the number of required pins.
