Get The 8051 Microcontroller

A microcontroller (MCU for microcontroller unit) is a small computer on a single metal-oxide-semiconductor (MOS) integrated circuit (IC) chip. A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals.

8051 microcontroller is designed by Intel in 1981. It is an 8-bit microcontroller. It is built with 40 pins DIP (dual inline package), 4kb of ROM storage and 128 bytes of RAM storage, 2 16-bit timers. It consists of are four parallel 8-bit ports, which are programmable as well as addressable as per the requirement.

For internal functioning & processing Microcontroller, 8051 comes with integrated built-in RAM. This is prime memory and is employed for storing temporary data. It is an unpredictable memory i.e. its data can get be lost when the power supply to the Microcontroller switched OFF.

The 8051 is a Harvard architecture. ... CODE memory and DATA memory are physically separate memory areas. There is no way to write to the CODE memory.

Brief History of 8051 In 1981, Intel introduced an 8-bit microcontroller called the 8051. It was referred as system on a chip because it had 128 bytes of RAM, 4K byte of on-chip ROM, two timers, one serial port, and 4 ports (8-bit wide), all on a single chip.

This has led to several versions with different speeds and amounts of on-chip RAM.

Intel developed the 8051 series of microcontrollers in 1980 for embedded systems. They should have been extinct by now, but they are still around and are, in fact, quite popular. ... The newer variants of the 8051 currently available in the market are more powerful, consume less power, and, most importantly, are cheaper.

Application of Microcontroller 8051. The use of microcontroller in various fields such as automobile, aeronautics, space, robotics, electronics, defense application, mobile communications, rail transport, industrial processing, and medical applications is rapidly increasing.
