Why 8051 is called 8 bit micro controller?
A: Because it can only control 8 bits of data.
Circuit diagram of IR TV remote control using 8051 microcontroller also explain its working?
the 8051 is a micro controller the buttons tell the 8051 to do something there is an ir led on an output bit of the 8051 that shines on the tv ir detector it pulses a code the tv knows or window fan, ac , vcr, dvd the other output bits are used to scan multiple buttons like the difference between a rotary and touch tone Phone ive seen them with tms1000 and z8 thermostats may have 68hc11 it has 8 channel a/d right on it circuit diagram is very trivial its all in how you pulse the led
Differences between Intel 8051 and atmel 89c51 micro controller?
The instructions used by Atmel 89CXX and 89CXXXX are the same or subset of 8051 microcontrollers.Fully static operation,flash program memory,less pin count andprecision analog comparator ( in case of 89C20510)are some of the attractions in going for these microcontrollers. Due to many similar features in the architecture and instruction and instruction set as that of 8051, it becomes possible for the 8051 designer to directly start using 89CXX and 89C20XX microcontrollers without any more efforts in learning these microcontrollers.
How do you connect LCD to microcontroller?
Yes, but you'll need way more detail than you can get from a simple answer. You need: The 8051 micro, an LCD interface the LCD, and software to get the 8051 to drive the LCD. You may be able to find a kit/project that already contains these items.
How much voltage is required to energize the 8051 microcontroller?
The 8051 runs on +5vdc.
What is a 8051 Micro-controller?
It is a small control chip.
What are 8051 based systems?
The 8051 is a micro-controller series, basically a computer on a chip. A system based on the 8051 series micro-controller is simply that, a device or series of devices that operate under control of one or more 8051 micro-controllers.
Why 8051 is called 8 bit micro controller?
A: Because it can only control 8 bits of data.
How temperature is measured using 8051 micro-controller?
how temperature is measured using 8051 micro-controler?
Is there any software by which you can control motors?
There is no such software that can directly control. There is need of Mechanical parts to carry out the signals processed by software. Simply write a program in C,C++ for a PIC 8051 micro controller and attach it.
Difference between avr micro controller and 8051 micro controller?
constructed on a single chip is called micro processor constructed on a single board is called micro controller
How do you write the 8051 micro controller alp for finding the largest number in an array?
1
What is purpose of ram in 8051 micro controller?
the internal RAM is for data storage and for many applications is all that is needed.
What are the advantages of PIC micro controller over 8051?
In general, personal preference and experience is what it comes down to. There are some PIC's that have built in RF systems; I don't believe there are any 8051's with this capability.

How many ports in 8051 micro controller?
They are mainly four ports in 8051MC. port 0 port 1 port 2 port 3
Why you use 12mhz in 8051 micro controller?
Like many early microprocessors it has a 1mhz internal clock for its' operation. 12mhz is divided internally by 12 to derive this frequency.
