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 chips considerably faster.

AT89C52 | 89C52 Microcontroller Datasheet & Pin Description

Blog Archive There are two different memory types: This allows a great amount of legacy code to be reused without modification in new applications. 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.


You can follow any responses to this entry through the RSS 2. Otherwise the port pin is stuck at 0. Telecommunication and Electronics Projects.

Each consists of a latch Special Function Registers P0 through P3an output driver, and an input buffer. Those ports can be used to output DATA and orders do other devices, or to read the state of a sensor, or a microxontroller. By using this site, you agree to the Terms of Use and Privacy Policy.

Views Read Edit View history. The alternate functions can only be activated if the corresponding bit latch in the port SFR contains a 1.

Atmel AT89 series

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’. From Wikipedia, the jicrocontroller encyclopedia.

Retrieved from ” https: 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 microckntroller DIL DIP packages.

Hello, this very post is related to the RPM meter project.

AT89S52 – Microcontrollers and Processors – Microcontrollers and Processors

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.

The output drivers of Ports 0 and 2, and the input buffers of Port 0, are used in accesses to external memory. Port 2 outputs the high byte of the external memory address when the address is 16 bits wide.

A simpler architecture can be represented below. Convert to Blogger by SimplexDesign.

It has less complex feature than other microprocessor. Most of the ports of the 89S52 have ‘dual function’ meaning that they can be used for two different functions. You can help Wikipedia by expanding it.
