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.

89S52 Microcontrollers IC

There are two different memory types: Contrast Setting, connected to Vcc thorough a variable resistor. The below points are just suggestions which might help one to select a MCU. Each MCU has its own advantage and disadvantage. Can u tell me how to store multiple strings into LCD? Some important command instructions are given below: You must first of all glance over the project here. Some important command instructions are given below:.

In order to program the Atmel microcontroller we will need an IDE Integrated Development Environmentwhere the programming takes place. 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’. Generally this is set to 0, because we do not have need to read data from LCD. And set it to 1, if we are reading from LCD module.

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


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

AT89S52 Microcontroller Pinout, Pin Configuration, Features & Datasheet

RS is the register select pin. Agree with you harish kumar Microxontroller you got the solution kindly share with us. However you can utilise external modules for the same.

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. Feel free 98s52 leave a response. Most of the ports of the 89S52 have ‘dual function’ meaning that they can be used for two different functions. Blog Archive Designed by Gabfire Themes. The datasheet of the AT89S52 Microcontroller and more detailed Features can be found at the bottom of this page.

Their collection has just piled up after Microchip has acquired Atmel. This pin is used to enable the module when a high to low pulse is given to it.

AT89C52 Microcontroller

All the pins are clearly understandable by their name and functions, except the control pins, so they are explained below:. TL — Programmable Reference Voltage. Hello, this very post 889s52 related to the RPM meter project.

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.

Convert to Blogger by SimplexDesign. Code Explanation I have tried to explain the microcontrolleer 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 sufficient time to execute the internal operation and commands.


Filed under DescriptionHow Stuff Works? Check your circuit connections again. Log in or register to post Comment. You can follow any responses to this entry through the RSS 2.

Mircocontroller and Order boards in minutes on https: Atmel microcontroller can be programmed with different software’s that is available in the market. Although it may be time taking because you need to understand and connect 16 pins of LCD to the microcontroller. A simpler architecture can be represented below.

I have used these Pins in above circuit. Submitted by admin on 12 September The above video shows lcd interface on bread board Can this project be shown on general purpose board??? Can I use blue character display instead of green. Also simulating you program on software before trying it on hardware will save a lot of time. Get Our Weekly Newsletter! Getting Started with Microcontroller. Posted by Muhammad Ahmed on Since it is similar to the trust worthy architecture these microcontrollers are as per industry standard.

So first let’s understand the 16 pins of LCD module. 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 microcontrollee 89S52, where the function of each pin is written next to it, and, if it exists, the dual function is written between brackets.
