Microcontroller 8051

8051 microcontroller pin diagram description The Intel 8051 microcontroller is one of the foremost well-liked general-purpose microcontrollers in use these days. 

The success of the Intel 8051 spawned a variety of clones that area unit put together noted because of the MCS-51 family of microcontrollers, which has chips from vendors like Atmel, Philips, Infineon, and TX Instruments. About the 8051.

The Intel 8051 is associated 8-bit microcontroller which implies that the majority of the market operations area unit is restricted to eight bits. There are unit three basic "sizes" of the 8051: Short, Standard, and Extended. 

The Short and normal chips area unit is typically on the market in DIP (dual in-line package) type, however, the Extended 8051 models typically have a unique type issue, and don't seem to be "drop-in compatible". of these things, area units are referred to as 8051 as a result of they'll all be programmed mistreatment 8051 programing language, and they all share bound options (although the various models all have their own special features).

·         4 kilobytes of on-chip program memory.

·         128 bytes of on-chip knowledge memory(RAM).

·         4 reg banks.

·         128 user-outlined code flags.

·         8-bit knowledge bus

·         16-bit address bus

·         32 general-purpose registers every of eight bits

· 16-bit timers (usually two, however, could have a lot of, or less).

·         3 internal and a pair of external interrupts.

·         Bit yet as computer memory unit available RAM space of sixteen bytes.

·         Four 8-bit ports, (short models have 2 8-bit ports).

·         16-bit program counter and knowledge pointer.

·         1 unit of time instruction cycle with twelve megahertz Crystal.

8051 models may have a variety of special, model-specific options, like UARTs, ADC, OpAmps, etc...The projected system is predicated on the 8051 μcontroller that is in our info. For doing this project we have a tendency to use a number of codes like Eagle code is employed for designing the PCB for this project. (Since PCB creating may be a massive method that involves a ton of types of machinery that area unit dear, 

we have a tendency to area unit reaching to source this to the manufacturer.)IC8051 is one of the favored microcontrollers. it's solely twenty pins and their area unit of fifteen input/output lines. The microcontroller contains a program memory of 2Kilobytes. 

The microcontroller endlessly monitors the device feed and if somebody enters sensors can give data to the info process unit. This counter device accommodates three Sections as follows: Detect Object (Sensor), processing (CPU), and final section shown by the LCD module.
