The invention of microprocessor was a milestone to the introduction of microcontroller. The first microprocessor was pioneer in 1971 by Intel. It was the 4 bit microprocessor with the clock speed of 740 Khz. It knows as Intel 4004 and the first commercial Cpu in singular chip.
Three years later Intel had manufactured 8 bit microprocessor of Intel 8080. It was determined by many to be the first true microprocessor general purposes used. It has used in variety applications such as traffic light and cash register. The Altair 8800 was one of the first computer as well used the microprocessor.
The complexities of microprocessor had driven to introduce of microcontroller. In order to be used microprocessor other component need to be adding externally such as memory, input port and yield port. Any way microcontroller had combining the Cpu, memory, peripheral, input-output function and analog to digital converter in singular chip.
The year of 1976 was a necessary in microcontroller history. Intel had invented the first world microcontroller. The microcontroller were Intel 8048 and Intel 8748. Since then the uses of microcontroller was growth every year with dozen of vendors. The tasteless vendors to the day were Intel, Freescale, Microchip, Arm and Atmel.
In 1993, the introduction of Eeprom had pump up Microchip sales with their famous chip of Pic16C84. It is allowed to be erase memory electronically and quickly. This electrically erasable memory made it cost less than Cpu that required quartz "erase window" for erasing Eprom.
Later on the Pic16F84 had introduced due to replacing Eeeprom with flash memory. As the affected the cost of singular chip plummeted over time. In 2009 the cheapest 8 bit microcontroller available with cost of .25 in quantity of thousands. Nowadays the microcontroller are low-cost and easily available for hobbyists, with large online communities nearby inescapable processors for hobbyists, with large online communities nearby inescapable processors.
