Embedded - Microcontrollers

Microcontrollers are electronic components embedded into computers, networks and other systems, containing instructions to control and process functions within the system. The PIC16C72-20E/SO is one of these microcontrollers, and it is widely used in various application fields, including embedded systems, automotive systems, data acquisition and control systems. This article will explore the PIC16C72-20E/SO application field and working principle.

Applications of the PIC16C72-20E/SO

The PIC16C72-20E/SO is a highly integrated, small-scale 8-bit CMOS Microcontroller, designed for embedded systems and other applications. It is powered by an enhanced CISC CPU, with one four-level deep internal stack, and built-in multiple oscillator types. Its primary application is for embedded systems, as it is capable of executing up to 800 instructions per second (IPS), which makes it suitable for many control applications. Additionally, the PIC16C72-20E/SO has up to 16KB flash program memory, 1KB of RAM, 256 Bytes of EEPROM, 16-bit Counter/Timers, two 8bit Parallel Ports and two serial ports. The PIC16C72-20E/SO has a wide range of applications in the automotive industry, such as engine control, ABS systems, infotainment systems and telematics. It is typically used to control low-level operations, and is also used for data acquisition and control systems. In automotive safety systems, the PIC16C72-20E/SO is used to detect and control hazardous conditions, providing enhanced protection for occupants and vehicle systems. It is also commonly used in industrial automation and robotics, providing precise speed and position control of Motors, actuators and other devices.

Working Principle of the PIC16C72-20E/SO

The PIC16C72-20E/SO is powered by the RISC (Reduced Instruction Set Computer) architecture. This allows the processor to execute instructions very quickly, and to use a smaller amount of space to execute the same number of instructions, compared to other architectures. The RISC architecture is also capable of utilizing multi-cycle instructions, where multiple instructions can be executed or in a single clock cycle. Additionally, the PIC16C72-20E/SO has multiple clock sources, which are divided into two groups: oscillator clocks and external Clock sources. The RISC processor architecture is also the basis for the internal register of the PIC16C72-20E/SO. This register is divided into different sections, and each section plays a different role in the Microcontroller’s operation. The Instruction Register is where the processor stores the instruction it is processing, and it is also responsible for looping through instructions. The Program Counter is used for tracking the position of the currently executing instruction, and for managing control flow. The Status Register stores the condition of the processor, such as Zero Flag and the Carry Flag. The Data Bank Register is responsible for storing the data and code that the program uses. The Stack Pointer is used for keeping track of the program\'s position when it is branching. The Vector Reload Register is responsible for loading the address of the interrupt within the interrupt vector table.

Conclusion

The PIC16C72-20E/SO is a highly versatile and efficient Microcontroller, which is widely used in embedded systems, automotive systems and data acquisition, and control systems. It is powered by the RISC architecture and has multiple clock sources and a versatile register architecture for more efficient execution of instructions. Its multiple clock sources provide enhanced stability, and it is suitable for many control applications, such as engine control and hazardous condition detection problems.
