What is the use of AT89C51 microcontroller?
The AT89C51 is an age old 8-bit microcontroller from the Atmel family. It works with the popular 8051 architecture and hence is used by most beginners till date. It is a 40 pin IC package with 4Kb flash memory. It has four ports and all together provide 32 Programmable GPIO pins.
How many pins are in AT89C51?
40 pins
Microcontroller 89c51 consists of 40 pins. There are four ports which are designed as P0, P1, P2 andP3. In these 40 pins P1, P2 and P3 are 8-bit bi-directional ports.
Is 8051 better than Arduino?
Arduino boards are present in logic 5 volts and 3.3 volts. This makes arduino more versatile than 8051. We can interface 5 volt logic devices with 5 volt logic boards and 3.3 volt sensors with 3.3 volts boards. We don’t need to have a level converter.
What is the bit size of the 89C51 microcontroller?
AT89C51 is an 8-bit microcontroller and belongs to Atmel’s 8051 families. ATMEL 89C51 has 4KB of Flash programmable and erasable read only memory (PEROM) and 128 bytes of RAM.
Where is 8051 used?
The 8051 Microcontroller is one of the most popular and most commonly used microcontrollers in various fields like embedded systems, consumer electronics, automobiles, etc.
Why 8051 is widely used?
Automobiles: The microcontroller 8051 discovers broad recognition in supplying automobile solutions. They are extensively utilized in hybrid motor vehicles to control engine variations. Also, works such as cruise power and anti-brake mechanism have created it more capable with the amalgamation of micro-controllers.
What is a microcontroller and what does it do?
A microcontroller is a compact integrated circuit designed to govern a specific operation in an embedded system. A typical microcontroller includes a processor, memory and input/output (I/O) peripherals on a single chip.
