C8051F819-GM Application Field and Working Principle

The C8051F819-GM is an integrated 8-bit microcontroller specifically designed for embedded applications. It is an 8051-based MCU, the 8051 nickname coming from the Intel 8-bit microcontroller family originally manufactured by Intel in the 1980s. By combining engineering design and operational control, the C8051F819-GM is an ideal choice for a variety of embedded applications.This 8-bit microcontroller is based on an 8051 core architecture, making it suitable for applications where higher controller complexity is preferred over immense computing power and embedded memory. The C8051F819-GM uses 40-pin packages and has a wide range of capabilities, including a 12-bit Analog-to-Digital Converter, a Pulse Width Modulation unit and two serial communication ports, making it suitable for applications such as energy metering, lighting control, automotive applications and a wide range of industrial applications. The C8051F819-GM is based on a 8051 architecture and uses a Harvard bus architecture. This bus architecture is applied both to the internal RAM as well as peripherals and external memory. In the Harvard architecture, instructions and data are kept separate, allowing the instruction and data buses to operate on different speeds. The 8051 core architecture also incorporates four distinct types of memory, which are the Program Memory, Data Memory, Bit Memory and Map Memory. The program memory is used for storing the program instruction, while data memory is used for storing data. The Bit Memory is used for controlling and manipulating the digital I/O ports, whereas the Map Memory is used for mapping I/O addresses. The C8051F819-GM also comes with several built-in peripherals like its 12-bit Analog-to-Digital converter (AD) and power supply interface, that help in its application support. The AD provides a means to convert analog signals like voltage, temperature and pressure into digital data. This capability enables the C8051F819-GM to be used in a variety of monitoring and measurement applications. The power supply interface enables the microcontroller to be easily powered by a single 3V operating voltage supply. This reduces the component count and system size at a cost of slightly reduced performance. The interface also simplifies the process of debugging while using the microcontroller, as the Power Supply interface provides various "parameters" that can be analysed. The C8051F819-GM also features two serial communication ports, a UART and an I2C bus. This makes the microcontroller highly attractive for applications such as remote controls, in which communication between the microcontroller and other peripherals is required. The UART port offers full control of the hardware and software of a serial data link, while I2C provides an easy and cost-effective way to interface between different components such as LCD displays, sensors, and more. In summary, the C8051F819-GM is an 8 bit microcontroller which combines engineering design and operational control with a wide range of capabilities in a 40-pin package. It is based on an 8051 architecture and uses a Harvard bus architecture, and features a 12-bit Analog-to-Digital Converter, a Pulse Width Modulation unit and two serial communication ports. Its power supply interface simplifies the process of debugging while using the microcontroller, while UART and I2C ports enable the microcontroller to be used in various applications such as energy metering, lighting control, automotive applications and a wide range of industrial applications.

Conclusion

The C8051F819-GM is an 8-bit microcontroller designed specifically for embedded applications.
