Microcontrollers are specialised computer systems embedded into a single integrated circuit with transistors and capacitors, whereby input commands are processed and output results are generated for different applications. The DS87C520-MNL+ is a 32-bit microcontroller especially designed for embedded system applications. It includes 64k of ROM and 512 bytes of RAM, high-speed instruction execution, on board interrupt service, low power consumption, and pull up/down resistors. It is suited to highly-demanding applications such as automotive, industrial and medical systems.

The applications of the DS87C520-MNL+ include automotive systems, medical systems, industrial automation, networking, process control, and signal transmission. Automotive applications of the microcontroller can range from communication systems, airbags systems, safety systems, infotainment, in-vehicle diagnostics, and engine control. Applications in medical systems include patient monitoring, medical imaging, and surgery control. In industrial automation, the microcontroller is used in the control of robots, machine automation, process control, and other real-time control tasks. In networking, the microcontroller is used in the design of switches, routers and gateways. In signal transmission, the microcontroller can be used for signal detection, encoding, decoding and also for power management.

The working principle of the DS87C520-MNL+ is based on the Von Neumann architecture. It consists of a single loop, where the input instruction is first fetched from the ROM, then executed and followed by the output data. The key components of the microcontroller are the ROM, RAM, clock generator, CPU, timer, and other peripherals which communicate with each other. The ROM stores the input instruction that the CPU fetches and executes. The RAM stores the data for manipulation. The clock generator drives the system controlled by the CPU which contains the registers and instruction decoder. The timer and other peripherals act as the input and output for the control signals used in external system control.

The microcontroller has numerous advantages both in terms of performance and price. Firstly, its on board interrupt service offers a null response time from external stimuli to service interrupt requests, making it suitable for real-time control applications. Secondly, its built-in on board pull up/down resistors allow it to be easily connected to other systems without the need for external components. Thirdly, its low power consumption offers greater energy savings than other microcontrollers. Finally, its low cost makes it an attractive choice for embedded system designs.

The DS87C520-MNL+ is a versatile and powerful microcontroller which is ideal for a wide range of embedded system applications. Its Von Neumann architecture and on board interrupt service make it suitable for real-time control applications. Its low power consumption and low cost makes it an attractive choice for embedded system designs. In addition, its on board pull up/down resistors deliver enhanced performance and simpler connections with other systems. All of these features combine to make the microcontroller an excellent choice for embedded system designs.
