Introduction

The PIC16C74A-10/PQ microcontroller is a very common, reliable and widely used 8-bit embedded microcontroller. It belongs to the Microchip PIC microcontroller family. It contains highly integrated CMOS functions, including an up to 96 byte RAM and 4 k×14 OTP Program Memory. The different CPU cores can operate up to 10 MIPS (10 million instructions per second). What makes it so popular is the very low power dissipation while high performance. This makes it ideal for applications that require low power consumption.

Application Field and Working Principle

The PIC16C74A-10/PQ has wide numerical application fields. It can be used for controlling motors, industrial automation and machine control, home appliances, embedded systems development, automotive and telecommunications.The PIC16C74A-10/PQ works on the basis of the RISC (Reduced Instruction Set Computing) architecture. It is also known a "CISC" (Complex Instruction Set Computing) architecture. This architecture allows the microcontroller to execute instructions very quickly. The features of the PIC16C74A-10/PQ include two-level priority interrupts and a programmable timer. This allows fast context switching, flexible interrupt handling and efficient use of computing time. The PIC16C74A-10/PQ also offers a built-in watchdog timer (WDT), which can reboot the system in case of unexpected shutdown or system glitch. The WDT is very useful in preventing deadlock situations.The PIC16C74A-10/PQ supports up to 8 I/O lines and 8k of program memory. The memory can be used to store instructions and data. It also supports up to four external interrupts. The power consumption of the PIC16C74A-10/PQ is very low compared to other microcontrollers. The maximum power consumption of the PIC16C74A-10/PQ is only 28mA at 4V and a maximum speed of 10MIPS, which makes it ideal for low-power battery-operated applications.

Conclusion

In conclusion, the PIC16C74A-10/PQ microcontroller is a very powerful and versatile 8-bit embedded microcontroller.
