Microchip Technology Inc
Currently, the market microcontrollers rapidly, thanks to the widespread introduction of microcontroller technology in control systems, as well as in many other areas are increasingly displacing the market system based on strict logic. Microcontrollers can in the shortest time to develop and produce electronic devices of almost any complexity. At the moment the market is represented by MCU production of more than 30 companies, including U.S. firm Microchip Technology Inc., producing a wide range of microcontrollers series PIC, which has become very popular among electronics manufacturers, and among hobbyists. One reason for this popularity can be called a competent marketing policies pursued by Microchip.
In addition, PIC microcontrollers combine a number of advanced technologies: it is developed RISC-architecture, minimal power consumption, high performance, EEPROM and other technical characteristics of the microcontroller PIC16F84 made him very popular among amateur and experimental development and individual devices. The presence of reprogrammable memory, and is easy to use and learn, make PIC16F84 microcontroller ideal for the manufacture of experimental samples and studying the principles of working with microcontrollers. PIC microcontrollers are ideal for development of small and medium-sized businesses in the production of electronic equipment. With minimal time and money can be easy to manufacture various electronic devices, ranging from electronic clock and ending with office PBX systems, and in such devices from 30 to 90 percent of the functionality implemented by software, which can be changed as needed and modified, based on the needs of the consumer. In addition, in some cases is an important opportunity to protect program code from unauthorized reading and modification. Having this option effectively protect copyright rights of producers and developers. In early models of microcontrollers had the opportunity to remove protection from the software when using special equipment, but the removal of such protections has been and remains very expensive and time-consuming procedure. In modern microcontrollers has been improving the system of protection code, which is almost completely eliminated the possibility of unauthorized reading or modification of software code.
