Introducing PIC Microcontroller : History, Application, and Series of PIC Microcontroller

Robometricschool. - One again microcontroller that very popular in industry application is PIC microcontroller. Some of experience said that using PIC microcontroller will get good stable for controlled DC motor and others. So, many people like use PIC microcontroller because this reason.

In this time will discuss about introduction PIC microcotroller  that you can use as guidance when you want tolearn more PIC microcotroller. Here are global information that you can know about PIC microcontroller.

PIC microcontrollers ( Programmable Interface Controllers), are electronic circuits that can be programmed to carry out a vast range of tasks. They can be programmed to be timers or to control a production line and much more. They are found in most electronic devices such as alarm systems, computer control systems, phones, in fact almost any electronic device. Many types of PIC microcontrollers exist, although the best are probably found in the GENIE range of programmable microcontrollers. These are programmed and simulated by Circuit Wizard software.

According the history of PIC microcontroller that The PIC microcontroller was developed by General Instruments in 1975. PIC was developed when Microelectronics Division of General Instruments was testing its 16-bit CPU CP1600. Although the CP1600 was a good CPU but it had low I/O performance. The PIC controller was used to offload the I/O the tasks from CPU to improve the overall performance of the system.

And than In 1985, General Instruments converted their Microelectronics Division to Microchip Technology. PIC stands for Peripheral Interface Controller. The General Instruments used the acronyms Programmable Interface Controller and Programmable Intelligent Computer for the initial PICs (PIC1640 and PIC1650).

And the next that in the year 1993, Microchip Technology launched the 8-bit PIC16C84 with EEPROM which could be programmed using serial programming method. The improved version of PIC16C84 with flash memory (PIC18F84 and PIC18F84A) and then it hit the market in 1998. 

When we tell about application of PIC microcontroller we can find many tools that design with PIC microcotroller as like for laboratory tools. There many application PIC microcontroller for laboratory tools likes for measuring instrument enumerator number of turns the motor using PIC16F84, temperature measuring devices using PIC16F877A with thermocouple sensors, DC motor speed measuring devices using the PIC16F877, etc.
