ARCHITECTURE OF 89C51 MICROCONTROLLER. The internal logic design of a device is called its architecture. The microcontroller architecture [1]. Microcontroller Architecture. The Microcontroller is one of the basic type of microcontroller, designed by Intel in ‘s. The 89C51/89C52/89C54/89C58 contain a non-volatile FLASH program memory that is parallel Details, datasheet, quote on part number: 89C

That information could be a byte of data to be processed, or an address pointing to the data to be fetched.

Must by cleared by software. The memory which is used to store the program of the microcontroller is known as code memory or Program memory of applications. They are addressed as 0 to in decimal or 00 to 7FH.

Answer Tips Double click any word to see the meaning. GND; Pin 20 is the Ground 8c951. Let us have a look at each part or block of this Architecture of microcontroller. Port P 0 and P 2 are also used to provide low byte and high byte addresses, respectively, when connected to an external memory.

Features of microcontroller 89c51 – Polytechnic Hub

These programs require a memory on which these can be saved and read by Microcontroller to perform specific operations of a particular task. The output pulses of oscillator are stable. Microcontroller requires a program which is a collection of instructions. What is Web Browser. Therefore, it enables synchronized work of all parts of the Microcontroller.


All come with on-chip ROM to store programs. The data memory of the is used to store data temporarily for operation is known RAM memory. This is very clear information and knowledge about microcontroller s0 thanks of and God bless you. As we know that the CPU is the brain of any processing device of the microcontroller. In each case, the lower 2 89c1 are used to set the timer mode and the upper 89cc51 bits to specify the operation.

Generally five interrupt sources are there in Microcontroller. Subscribe via email New posts will be send to you via email Enter your email address: One side of each capacitor is connected to the ground as shown in this figure; EA; The family members, such as the89C51, or DS This is just like mode 1.

Learn (For Beginners): AT89C51 Description

To repeat the process, we must simply clear TF and archjtecture it go without any need by the programmer to reload the original value. Do you have any innovative ideas to implement the microcontroller based electronics projects?


For any technical information please refer our blog: Choosing Battery for Robots. When connecting an to external memory, port 0 provides both address and data. In such cases, the EA pin is connected to VCC for giving power to save and erase program from the memory.

Architecture 8051 Microcontroller and Block Diagram with Applicarions

The timers are used for measurement of intervals to determine the pulse width of pulses. Hi Milan Mahetha As per your query please follow the below link https: Port 3; is a dual — purpose port on pins These ports are also bit addressable and so their bits can also be accessed individually. Hire two types of buses that are shown in below. All the registers of 89C51 are.

This makes mode 2 and auto-reload, in contrast with mode 1 in which the programmer has to reload TH and TL. Supply voltage; 5V up to 6.
