series introduction
# Introduction to the STR91X - SK/HIT Product Series
## Overview
The STR91X - SK/HIT product series represents a cutting - edge line of microcontroller development kits that are designed to meet the diverse needs of embedded system developers. These kits are built around the powerful STR91X family of microcontrollers, offering a comprehensive platform for rapid prototyping, product development, and educational purposes.
## Key Features of the STR91X Microcontrollers
### High - Performance CPU
The STR91X microcontrollers are based on a high - performance ARM966E - S core. This core provides a clock speed of up to 72 MHz, enabling fast execution of complex algorithms and real - time tasks. With its advanced pipeline architecture, the ARM966E - S core can handle multiple instructions simultaneously, resulting in improved overall system performance.
### Rich Peripheral Set
- **Communication Interfaces**: The STR91X series offers a wide range of communication interfaces, including UART, SPI, I2C, and CAN. These interfaces allow the microcontroller to communicate with various external devices such as sensors, actuators, and other microcontrollers. For example, the UART interface can be used for serial communication with a PC, while the CAN interface is suitable for automotive and industrial applications where reliable communication over long distances is required.
- **Timers and Counters**: Multiple timers and counters are integrated into the STR91X microcontrollers. These timers can be used for a variety of purposes, such as generating precise time delays, measuring time intervals, and controlling PWM signals. The PWM outputs can be used to control the speed of motors or the brightness of LEDs.
- **Analog - to - Digital Converters (ADCs)**: The microcontrollers are equipped with high - resolution ADCs. These ADCs can convert analog signals from sensors (such as temperature sensors, pressure sensors, etc.) into digital values, allowing the microcontroller to process and analyze the sensor data.
### Memory Options
- **Flash Memory**: The STR91X microcontrollers come with a large amount of on - chip flash memory, ranging from 128 KB to 512 KB. This flash memory can be used to store the program code, allowing for easy firmware updates and modifications.
- **SRAM**: In addition to flash memory, the microcontrollers also have a significant amount of on - chip SRAM, typically 32 KB to 64 KB. The SRAM is used for storing variables, data buffers, and stack space during program execution.
## Features of the STR91X - SK/HIT Development Kits
### Easy - to - Use Hardware
- **On - Board Debugging**: The STR91X - SK/HIT kits are equipped with on - board debugging capabilities, which simplifies the development process. Developers can use the integrated debugger to step through the code, set breakpoints, and monitor the values of variables in real - time.
- **Expansion Connectors**: The kits feature expansion connectors that allow developers to easily connect external modules and sensors. This provides flexibility in adding additional functionality to the development platform, such as wireless communication modules, display modules, or sensor arrays.
### Comprehensive Software Support
- **Integrated Development Environment (IDE)**: The STR91X - SK/HIT kits are supported by a powerful IDE, which provides a user - friendly interface for writing, compiling, and debugging code. The IDE includes features such as code editors, compilers, linkers, and debuggers, all in one package.
- **Software Libraries**: A set of software libraries is provided with the kits, which simplifies the development process. These libraries include drivers for the various peripherals of the STR91X microcontrollers, as well as middleware for common tasks such as file system management and network communication.
