The LM3S9790-IBZ80-C5T Microcontroller is an embedded system designed for use in a range of applications. This microcontroller is based on ARM Cortex-M3 Core architecture with a 32-bit processor, 64 B of on-chip Flash Memory, 16 MB of SRAM, and 128 KB of ROM. It has various built-in peripherals and interfaces, making it suitable for a wide range of applications.

The ARM Cortex-M3 Core architecture allows for high-performance computation, providing improved processing speed and efficiency compared to conventional microcontrollers. The 64 B of on-chip Flash Memory allows for a variety of code, data and application-specific data to be stored inside the microcontroller. This makes it suitable for applications that require intensive processing power, such as digital signal processing, data manipulation and communications. The 16 MB of SRAM provides a large amount of fast non-volatile memory space.

The built-in peripherals and interfaces of the LM3S9790-IBZ80-C5T Microcontroller include an 8-bit Multi-channel Buffered Serial Port, two 10-bit ADC Inputs, one 16-bit UART, one CANBUS, one SPI, and one I2C interface. The 8-bit Multi-channel buffered Serial Port supports up to 8 UART channels, which can be used for communications or for providing data for IO pins. The 10-bit ADC Inputs can be used for analogue signal measurement and the 16-bit UART interface provides a full-duplex serial communications protocol for two devices. The CANBUS interface is compatible with the ISO 11898-3 and SAEJ1939-1 standards and is designed for communication between nodes in a CAN network.

The SPI and I2C interfaces can be used for communication between two integrated circuits, and are used for sensor control, communication interfaces andother I/Os. The LM3S9790-IBZ80-C5T also has 32 GPIO pins which can be used to control external digital devices such as LEDs, keypad, EEPROM and LCD.

The LM3S9790-IBZ80-C5T is suitable for a wide range of embedded applications such as industrial automation, automotive, consumer electronics, medical devices and energy applications, as well as uninterruptible power supplies (UPS) and home automation systems. Its ARM Cortex-M3 Core, high performance peripherals and interfaces, plus wide range of device memory makes it suitable for a variety of applications that require high levels of computation and data storage.

The working principle of the LM3S9790-IBZ80-C5T Microcontroller is based on the concept of a von Neumann machine. The main components of the machine are the processor, memory and input/output (I/O) peripherals. The processor fetches instructions from the memory and executes them, as well as manipulating data from memory and I/O peripherals. The instructions and data from memory and I/O peripherals are stored in registers and can be accessed by the processor. The processor is responsible for the execution of instructions, while the I/O peripherals are responsible for handling data exchanged between the processor and other devices.

The LM3S9790-IBZ80-C5T Microcontroller has a Harvard architecture, which is similar to that of the von Neumann machine. The main difference is that the Harvard architecture uses separate address and data busses, which makes it possible for the processor to simultaneously access two different areas in the memory. Additionally, the Harvard architecture allows for simultaneous memory and I/O access, while the von Neumann architecture only allows for memory and I/O access one after the other. The Harvard architecture also allows for more efficient data movement and better communication bandwidth, making it the perfect choice for embedded microcontroller applications.
