What is microcontroller with diagram?
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.
Which microcontroller is 8051?
The Intel MCS-51 (commonly termed 8051) is a single chip microcontroller (MCU) series developed by Intel in 1980 for use in embedded systems. The architect of the Intel MCS-51 instruction set was John H. Wharton.
Why is it called 8051 microcontroller?
Term 8051 refers to MCS 51 family of microcontroller ICs introduced by intel corporation in 1971. A microcontroller is a computer with most of the necessary support chips on board. All computers have several things in common, namely: A central processing unit (CPU) that executes programs.
Why is it called 8051?
There was also a 2K ROM/128 byte version called the 8049, and finally a 4K ROM/256 byte version (which max’ed out the RAM address space) called the 8050. When Intel decided to create an expanded version to meet the needs of customers, they chose the next number in the series, 8051.
What are the advantages of 8051 microcontroller?
i )Low time required for performing operation. ii)The processor chips are very small and flexibility occurs. iii)Due to their higher integration, cost and size of the system is reduced. iv)The microcontroller is easily to interface additional RAM, ROM and I/O ports.
What is microcontroller explain in detail?
: an integrated circuit that contains a microprocessor along with memory and associated circuits and that controls some or all of the functions of an electronic device (such as a home appliance) or system.
What is the features of 8051?
RAM: 8051 Microcontroller has 128 Bytes of RAM which includes SFRs and Input / Output Port Registers. ROM: 8051 has 4 KB of on-chip ROM (Program Memory). I/O Ports: 8051 has four 8 – bit Input / Output Ports which are bit addressable and bidirectional. Timers / Counters: 8051 has two 16 – bit Timers / Counters.
Which architecture is used in 8051?
