Block Diagram 8051 Microcontroller Description. These ports are programmable as well as addressable as per requirement. We have also seen that there other packages of 8051 like the 44.
Clock pulses are required to synchronize the internal operation of the microcontroller these clock pulses are generated by the resonant circuitrypins xtal1 and xtal2 are provided for connecting a resonant network to form an oscillator. These ports are programmable as well as addressable as per requirement. The block diagram provided by atmel in their datasheet that showed the architecture of 89s52 device seemed a bit complicated.
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.
Clock pulses are required to synchronize the internal operation of the microcontroller these clock pulses are generated by the resonant circuitrypins xtal1 and xtal2 are provided for connecting a resonant network to form an oscillator. Block diagram of microcontroller 8051 cpu the cpu central processing unit comprising of alu arithmetic and logic units and control units alu arithmetic and logic unit performing the arithmetic and logical operations. It is a 40 pin dip dual inline package 8 bit device. 8051 microcontroller architecture.
