Block Diagram 8051

The block diagram of the 8051 microcontroller architecture shows that 8051 microcontroller consists of a cpu ram sfrs and data memory flash eeprom i o ports and control logic for communication between the peripherals.

Block diagram 8051. 8051 microcontroller is designed by intel in 1981. 8051 microcontroller architecture and block diagram explained a brief theory of 8051 microcontroller. The 8051 microcontroller is a general purpose microcontroller. As we know microcontroller is a digital circuit device.

It is built with 40 pins dip dual inline package 4kb of rom storage and 128 bytes of ram storage 2 16 bit timers. Let us see the major components of 8051 microcontroller and their functions. Alu arithmetic and logic unit 2. Now let us see the architecture and block diagram of 8051 microcontroller major components of intel 8051 microcontroller the 8051 microcontroller is an 8 bit microcontroller.

It consists of are four parallel 8 bit ports which are programmable as well as addressable as per the requirement. Architecture diagram the architecture of the 8051 microcontroller can be understood from the block diagram. Interrupts are subroutine call that interrupts microcontrollers main operation or work and causes it to. It has harward architecture with risc reduced instruction set computer concept.

Features of 8051 microcontroller 4kb bytes on chip program memory rom 128 bytes on chip data memory ram four register banks 128 user defined software flags 8 bit bidirectional data bus 16 bit unidirectional address bus 32 general purpose registers each of 8 bit 16 bit timers usually 2 but may. It has an 8 bit processing unit and 8 bit accumulator units. From our day to. Let us have a look at each part or block of this architecture of microcontroller.

Microcontroller requires programmers which is the collection of instruction these programs tells. Following diagram is 8051 microcontroller architecture. Embedded systems have revolutionized the electronics industry. Features of the 8051 microcontroller.
