What is 89c51?
The AT89C51 is a low-power, high-performance CMOS 8-bit microcomputer with 4K bytes of Flash programmable and erasable read only memory (PEROM). The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-standard MCS-51 instruction set and pinout.
Is 89c51 and 8051 same?
Actually 8051 is an architecture developed by Intel. And the controllers at89c51 & at89c52 are designed by atmel Corp based on Intel 8051 architecture. The basic difference between these two controllers is in their RAM memory and flash memory.
How many timers are available in 89c51 microcontroller?
two build
8051(89c51,89c52) series microcontrollers have two build in timers Timer-0 and Timer-1. You can use them as event counters, generating Time-delays, generating Baud Rates for serial communication or as an interrupt counter. Both the timers 0 and 1 are 16-bit wide.
What can you do with micro controllers?
Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems.

What is C in 89c51 microcontroller?
C stands for CMOS.
What required voltage for 89c51 is?
What is the main purpose of timer 1?
Timer 1 Register The low-byte register is called TL1 (Timer 1 low byte) and the high-byte register is called TH1 (Timer 1 high byte). These registers can be accessed like any other register. For example, the instruction MOV TL1, #4H moves the value into the low-byte of Timer 1.
How do you program a micro controller?
The Basics Of Microcontroller Programming
- write program code on your computer.
- compile the code with a compiler for the microcontroller you are using.
- upload the compiled version of your program to your microcontroller.
What is microcontroller PDF?
Microcontroller is a computer on single integrated circuit that includes a CPU, RAM, some form of ROM, and I/O ports. It has great impact in our life which cannot be ignored. Unlike a general purpose computer, microcontrollers are dedicated to perform a specified task and execute single application.
How does microcontroller get power?
There are three main DC voltage sources available to supply power for our microcontroller projects: Batteries, wall adapters or the USB port of a computer. Generally, the power level requirement is dictated by the requirements of the devices that you use to build the circuit.
How many ports are available in AT89C51?
Microcontroller 89c51 consists of 40 pins. There are four ports which are designed as P0, P1, P2 andP3.
