Each consists of a latch Special Function Registers P0 through P3an output driver, and an input buffer.
Atmel AT89 series
It has less complex feature than other microprocessor. In other projects Wikimedia Commons. Newer Post Older Post Home. The alternate microclntroller can only be activated if the corresponding bit latch in the port SFR contains a 1.

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’.
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. There are two different memory types: Convert to Blogger by SimplexDesign.
Port 2 outputs the high byte of the external memory address when the address is 16 microcontgoller wide. This allows a great amount of legacy code to be reused without modification in new applications. From Wikipedia, the free encyclopedia.
In this application, Port 0 outputs the low byte of the external memory address, time-multiplexed with the byte being written or read. Atmel has also created an LP low power series of these chips with a “Single Cycle Core”, making the execution speed of these microcontorller considerably faster.
AT89C52 | 89C52 Microcontroller Datasheet & Pin Description
Telecommunication and Electronics Projects. This microcomputer – or microprocessor -related article is a stub.
You can help Wikipedia by expanding it. Retrieved from ” https: The output drivers of Ports 0 and 2, and the input buffers of Port 0, are used in accesses to external memory.
You must first of all glance over the project here. 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.
Hello, this very post is related to the RPM meter project.
Filed under DescriptionHow Stuff Works? Blog Archive Otherwise the port pin is stuck at 0. Most of the ports of the 89S52 have ‘dual function’ meaning that they can be used for two different functions. A simpler architecture can be represented below. Feel free to leave a response. Those ports can be used to output DATA and orders do other devices, or to read the state of a sensor, or a switch.
