What are the advantages of pic microcontroller?
The pic microcontroller plays an important role as one of many people's work. But most people do not know why to use pic microcontroller, in order to solve this problem, we must talk about the advantages of pic microcontroller. With this article on the advantages of pic microcontrollers, I hope relevant people can have a certain grasp of pic microcontrollers, and fully understand why use pic microcontrollers and usage scenarios.
Advantage 1: The biggest feature of PIC is that it does not engage in simple function accumulation, but starts from reality, pays attention to the performance and price ratio of products, and develops various models to meet different application requirements. In reality, different applications have different requirements for microcontroller functions and resources. For example, a motorcycle igniter requires a small single-chip microcomputer of less I/O, small RAM and program storage space, and high reliability. If a 40-pin and powerful single-chip microcomputer is used, the investment is big and inconvenient to use.The PIC series has dozens of models from low to high to meet a variety of needs. Among them, PIC12C508 microcontroller has only 8 pins, which is the smallest microcontroller in the world.
This model has 512 bytes of ROM, 25 bytes of RAM, an 8-bit timer, one input line, and 5 I/O lines. Such a single-chip microcomputer is undoubtedly very suitable for applications such as motorcycle igniters. PIC's high-end models, such as the PIC16C74 (not the highest-end model), have 40 pins. The internal resources are 4K for ROM, 192 bytes of RAM, 8 channels of A/D, 3 8-bit timers, and 2* modules. Three serial ports, one parallel port, 11 interrupt sources, and 33 I/O pins. Such a model can compete with other brands of high-end models.
Advantage 2: Zero time to market. Using PIC's low-cost OTP chip, the microcontroller can be used to market the product immediately after its application development.
Advantage 3: Its pin has anti-transient capability. It can be connected to 220V AC power through the current limiting resistor. It can be directly connected to the relay control circuit without isolation of the optocoupler, which brings great convenience to the application.
Advantage 4: Streamlined instructions make their execution efficiency much better. The PIC family of 8-bit CMOS microcontrollers has a unique RISC architecture, a Harvard architecture with separate data bus and instruction bus, which allows the instruction to have a single word length and allows the number of bits of the instruction code to be more than 8 bits. Compared with the traditional 8-bit single-chip microcomputer with CISC structure, it can achieve 2:1 code compression and increase the speed by 4 times.
Advantage 5: Complete confidentiality. The PIC protects the code with a secure fuse. The user blows the fuse after burning the code, and others can no longer read it unless the fuse is restored. At present, PIC uses a deep buried fuse process, and the possibility of recovering the fuse is extremely small.
Advantage 6: PIC has a superior development environment. The real-time performance of the OTP microcontroller development system is an important indicator. The development system of the ordinary 51 single-chip microcomputer mostly adopts the high-end model simulation low-end model, and its real-time performance is not ideal. PIC introduced a new emulation chip at the same time as the launch of a new model. All development systems are supported by dedicated emulation chips, and the real-time performance is very good.
Advantage 7: The built-in watchdog timer can be used to improve the reliability of program operation.
Advantage 8: Sleep and low power modes. Although PIC is no longer comparable to the new TI-MSP430 in this respect, it is still adequate for most applications.
