With the development of electronic technology, embedded microcontrollers are widely used in various fields. TMS320F2808LITE is one of the most popular embedded microcontrollers, which is suitable for cost-sensitive applications in industrial and commercial markets. It provides superior performance, reasonable cost and reliable operation with excellent stability and durability. In this paper, the application field and working principle of TMS320F2808LITE will be discussed in detail.

As an embedded microcontroller, the TMS320F2808LITE has the advantages of low power consumption, low voltage operation and excellent stability. It has a ARM Cortex-M4F core and a 12-bit ADC and DAC for complex control applications. TMS320F2808LITE also supports a variety of communication protocols, including Ethernet, USB, CAN, UART and I2C, which is an excellent choice for applications requiring multi-channel communication. As an industrial-grade product, the TMS320F2808LITE has a wide range of applications, including industrial automation, medical equipment, robotics, security systems, automotive and so on.

As for the working principle of TMS320F2808LITE, its main block diagram is as follows. The system consists of a main power supply, CPU, memory, peripherals, interface, input/output (I/O) interface and PWM interface. The main power supply supplies power to the chip. The CPU is responsible for the control of the system. Memory includes external flash memory, SRAM, ROM and EEPROM. Peripherals contain serial communications, timer/counter units, A/D converter, D/A converter and DMA controller. The main characteristic of the interface is to drive the devices for data transfer and communication. The input/output (I/O) interface is designed to transfer data from external devices. The PWM output is used to generate pulse signals to drive motors and other devices.

In addition, the working process of TMS320F2808LITE is divided into six steps: execution of instructions, addressing/data acquisition, decoding of instructions, calculation of operands, execution of instructions and storage of results. Firstly, the PC sends instruction codes to the CPU. The CPU divides the code into several parts in sequence according to the addressing mode, and sends corresponding address of memory data（operands） and the type of instruction. The CPU reads the data of the operands and decodes the ready instructions. After that, the CPU executes the instructions and calculates the result. At last, the CPU stores the result in the register or RAM according to the assigned address.

In conclusion, embedded microcontrollers are widely used in various fields. TMS320F2808LITE is one of the most popular embedded microcontrollers, which is suitable for cost-sensitive applications in industrial and commercial markets. It has advantages of low power consumption, low voltage operation and excellent stability. Moreover, the working process of TMS320F2808LITE consists of six steps while its main block diagram contains several components. The detailed operation of TMS320F2808LITE provides an excellent choice for multi-channel communication applications.
