8051 Microcontroller Schematic Diagram. 8051 microcontroller architecture following diagram is 8051 microcontroller architecture. It is internally pulled up bi directional i o port.
Since it is a 40 pin dip ic each side contains 20 pins. We can see 3 system inputs 3 control signals and 4 ports for external interfacing. It has an 8 bit processing unit and 8 bit accumulator units.
Now lets explain and go through each in detail.
Pin and signal diagrams of the 8051 microcontrollermicro controller plc micro controller embedded systemelectronics 6th semester electrical 6th semesterc. It has an 8 bit processing unit and 8 bit accumulator units. We have also seen that there other packages of 8051 like the 44 lead plcc and the 44 lead tqfp. The block diagram of 8051 is as follows 8 bit microcontroller the 8051 microcontroller is an 8 bit microcontroller.
