The AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller with 8K bytes of in-system programmable Flash memory. The AT89S52 provides the. AT89S52 comes from the popular family of Atmel Microcontrollers. It is an 8- bit CMOS microcontroller with 8K as Flash memory and microcontroller is from Intel manufacturer and they’re the one who developed the basics version of microcontroller. So it’s like the first family of.

It is the CPU that will Read the program from the FLASH memory and Execute it by interacting with the different peripherals Diagram below shows the pin configuration of the 89S52, where the function of each pin is written next to it, and, if it exists, the dual function is written between brackets. Submitted by admin on 12 September Check your circuit connections again.

Get Our Weekly Newsletter! Circuit diagram for LCD interfacing with microcontroller is shown in the above figure.

Middle leg of the variable resistor is connected to PIN 3 and other two legs are connected to voltage supply and Ground. There are two microconyroller memory types: Diagram below shows the pin configuration of the 89S52, where the function of each pin is written next to it, and, if it exists, the dual function is written between brackets.


And we will set it to 0 if we are sending some command instruction like clear the screen hex code Some important command instructions are given below: Contrast Setting, connected to Vcc thorough a variable resistor.

Atmel microcontroller can be programmed with different software’s that is available in the market. Telecommunication and Electronics Projects. Feel free to leave a response.

However you 89s2 utilise external modules for the same. Hello, this very post is related to the RPM meter project. The Microcontroller also has Operating mode, Idle Mode and Power down mode which makes it suitable for battery operated applications.

Microcontroller AT89S52 Description – Telecommunication and Electronics Projects

Getting Started with Microcontroller. The below points are just suggestions which might help one to select a MCU. Enable, a high to low pulse need to enable the LCD. Designed by Gabfire Themes. So first let’s understand the 16 pins of LCD module. Quote and Order boards in minutes on https: Blog Archive Can u tell me how to store multiple strings into LCD?

A pulse of ns should be given. I have used microcobtroller Pins in above circuit. If you are planning on serious programming and expansion with community support then Keil is recommended.

This pin is used to enable the module when a high to low pulse is given to it.

AT89C52 Microcontroller

Generally this is set to 0, because we do not have need to read data from LCD. TL — Programmable Reference Voltage.


You must first of all glance over the project here. Microcotnroller with you harish kumar If you got the solution kindly share with us. Arduino, Keil uVision are the most used platforms to name a few. Also simulating you program on software before trying it on hardware will save a lot of time.

89S52 Microcontrollers IC

Shortly, RAM is used to store variable during program execution, while the EEPROM memory is used to store the program itself, that’s why it is often referred to as the ‘program memory’. Most of the ports of the 89S52 have ‘dual function’ meaning that they can be used for two different functions. Thanku for ur explanation and code.

Imcrocontroller simpler architecture can be represented below.

AT89S52 Microcontroller Pinout, Pin Configuration, Features & Datasheet

Code Explanation I have tried to explain the code through comments in code itself. Function msdelay has been created to create delay in milliseconds and called frequently in the program, it is called so that LCD module can have mivrocontroller time to execute the internal operation and commands.

Each MCU has its own advantage and disadvantage.
