What is microcontroller architecture?
A microcontroller is essentially a small computer on a chip. Like any computer, it has memory, and can be programmed to do calculations, receive input, and generate output. Unlike a PC, it incorporates memory, a CPU, peripherals and I/O interfaces into a single chip.
What are the applications of a microcontroller?
In the office, microcontrollers are used in computer keyboards, monitors, printers, copiers, fax machines, and telephone systems to name a few. In your home, microcontrollers are used in microwave ovens, washers and dryers, security systems, lawn sprinkler station controllers, and music/video entertainment components.
How many types of architecture are there in microcontroller?
The memory architecture of microcontroller are two types, they are namely: Harvard memory architecture microcontroller. Princeton memory architecture microcontroller.
Why it is called microcontroller?
It is so called because this device comprises of transistors which are small in size (micro-meter). The word micro is used in electronics and in science generally, to mean One-millionth or 10^-6. It has also used to denote something very small like a very small processor or micro controller.
What is the purpose of a microcontroller?
Microcontroller is a compressed micro computer manufactured to control the functions of embedded systems in office machines, robots, home appliances, motor vehicles, and a number of other gadgets. A microcontroller is comprises components like – memory, peripherals and most importantly a processor.
What are some applications of a 8051 microcontroller?
Energy Management: Competent measuring device systems aid in calculating energy consumption in domestic and industrialized applications.
What is the purpose of 8051 microcontrollers?
The 8051 Microcontroller is a general purpose Microcontroller . Though it is more than 50 years old, the 8051 microcontroller is still heavily used in a number of electronic and electrical devices. Moreover various industries such as automobile, mobile communications, defense, aeronautics, and even healthcare, would be inefficient without this small but powerful component.
What is the parallel port architecture of 8051?
The 8051 is based on an 8-bit CISC core with Harvard architecture. Its 8-bit architecture is optimized for control applications with extensive Boolean processing. It is available as a 40-pin DIP chip and works at +5 Volts DC. Four Parallel ports each of 8-bits (PORT0, PORT1, PORT2, PORT3) with a total of 32 I/O lines
What IC is used for 8051?
The IC L293D is used for interfacing 8051 with DC motor as shown in the block diagram. The two input buttons can be used to control the output PWM generated by the microcontroller. This output signal is then fed to DC motor through motor driver.
