Feel free to leave a response. Blog Archive Port 2 outputs the high byte of the external memory address when the address is microvontroller bits wide.

Retrieved from ” https: This allows a great amount of legacy code to be reused without modification in new applications. Shortly, RAM is used to store variable during program execution, while the EEPROM memory is used to mjcrocontroller the program itself, that’s why it is often referred to as the ‘program memory’. You can help Wikipedia by expanding it.

Hello, this very post is related to the RPM meter project. Convert to Blogger by SimplexDesign.

Posted by Muhammad Ahmed on In this application, Port 0 outputs the low byte of the external memory address, time-multiplexed with the byte being written or read. In other projects Wikimedia Commons.

Atmel AT89 series

It has less complex feature than other microprocessor. By using this site, you agree to the Microfontroller of Use and Privacy Policy. Those ports can be used to output DATA and orders do other devices, or to read the state of a sensor, or a switch.

There are two different memory types: Each consists of a latch Special Function Registers P0 through P3an output driver, and an input buffer. Filed under DescriptionHow Stuff Works? A simpler architecture can be represented below.

Atmel AT89 series – Wikipedia

The alternate functions can only be activated if the corresponding bit latch in the port SFR contains a 1. Otherwise the port pin is stuck at 0. This page was last edited on 16 Septemberat It is the CPU that will Read the program from microcongroller 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.

Telecommunication and Electronics Projects. Most of microcontrooller ports of the 89S52 have ‘dual function’ meaning that they can be used for two different functions. Designed by Gabfire Themes.

AT89S52 – Microcontrollers and Processors – Microcontrollers and Processors

From Wikipedia, the free encyclopedia. Based on the Intel core, the AT89 series remains very popular as general purpose microcontrollers, due to their industry standard instruction set, their low unit cost, and the availability of these chips in DIL DIP packages.

The output drivers of Ports 0 and 2, and the input buffers of Port 0, are used in accesses to external memory. 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.

You must first of all glance over the project here. Atmel has also created an LP low power series of these chips with a “Single Cycle Core”, making the execution speed of these chips considerably faster.
