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.

Blog Archive Telecommunication and Electronics Projects. TL — Programmable Reference Voltage. Each MCU has its own advantage and disadvantage.

If you are planning on serious programming and expansion with community support then Keil is recommended. And we will set it to 0 if we are sending some command microcintroller like clear the screen hex code Enable, a high to low pulse need to enable the LCD. A pulse of ns should be given. 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.

Arduino, Keil uVision are the most used platforms to name a few.

AT89S52 Microcontroller Pinout, Pin Configuration, Features & Datasheet

Getting Started with Microcontroller. The above video shows lcd interface on bread board Can this project be shown on general purpose board??? The datasheet of the AT89S52 8s52 and more detailed Micrcoontroller can be found at the bottom of this page.

  CSA A23.3-94 PDF

Newer Post Older Post Home. Circuit diagram for LCD interfacing with microcontroller is shown in the above figure. Those ports can be used to output DATA and orders do other devices, or to read the state of a sensor, or a switch. All the pins are clearly understandable by their name and functions, except the control pins, so they are explained below:. Hello, this very post is related to the RPM meter project. Pin 3 V0 is connected to microcontorller Vcc through a variable resistor of 10k to adjust the contrast of LCD.

The below points are just suggestions which might help one to select a MCU. Convert to Blogger by SimplexDesign. Submitted by admin on 12 September Feel free to leave a response.

Middle leg of the variable resistor is connected to PIN 3 and other two legs are connected to voltage supply and Ground.

Some important command instructions are given below: The Microcontroller also has Operating mode, Idle Mode and Power down mode which makes it suitable for battery operated applications. Filed under DescriptionHow Stuff Works? Agree with you harish kumar If you got the solution kindly share microcontrollet us. You must first of all glance over the project here.

So first let’s understand the 16 pins of LCD module. Some important command instructions are given below:. Also simulating you program on software before trying it on hardware will save a lot of time.

Their collection has just piled up after Microchip has acquired Atmel.

89S52 Microcontrollers IC

There are two different memory types: Designed by Gabfire Themes. 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 sufficient time to execute the internal operation and commands.


A simpler architecture can be represented below. Most of the ports of the 89S52 have ‘dual function’ meaning that they can be used for microcontrooler different functions.

RS is the register select pin. And set it to 1, if we are reading from LCD module. In order to program the Atmel microcontroller we will need an IDE Integrated Development Environmentwhere the programming takes place. Can I use blue character display instead of green. However you can utilise external modules for the same. Log in or register to post Comment.

This pin is used to enable the module when a high to low pulse is given to it. Microcontrller Explanation I have tried to explain the code through comments in code itself.

And control pins RS, RW and E to the pin 12,13,14 pin 2,3,4 of port 3 of microcontroller respectively. Posted by Muhammad Ahmed on It is the CPU that will Read the program from the FLASH memory and Execute it by interacting with 89s5 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.
