Those ports can be used microcohtroller output DATA and orders do other devices, or to read the state of a sensor, or a switch.
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.
Retrieved from ” https: Newer Post Older Post Home. The output drivers of Ports 0 and 2, and the input buffers of Port 0, are used in accesses to external memory. This allows a great amount of legacy code to be reused without modification in new applications.
You can follow any responses to this entry through the RSS 2. Feel free to leave a response. You must first of all glance over the project here. Otherwise the port pin is stuck at 0. Filed under DescriptionHow Stuff Works? 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’.
There are two different memory types: You can help Wikipedia by expanding it. Views Read Edit View history. Blog Archive From Wikipedia, the free encyclopedia. Most of the ports of the 89S52 have ‘dual function’ meaning that they can be used for two different functions. This page was last microconteoller on 16 Septemberat Convert to Blogger by SimplexDesign.
AT89S52 – Microcontrollers and Processors – Microcontrollers and Processors
In this application, Port 0 outputs the low byte of the external memory address, time-multiplexed with the byte being written or read. A simpler architecture can be represented below.
Each consists of a latch Special Function Registers P0 through P3an output driver, and an input buffer. Telecommunication and Electronics Projects. Port 2 outputs the high byte of the external memory address when the address is 16 microcontroloer wide. This microcomputer – or microprocessor -related article is a stub. The alternate functions can only be activated if the corresponding bit latch in the port SFR contains a 1.
Atmel AT89 series
Designed by Gabfire Themes. 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. 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.
