From Wikipedia, the free encyclopedia. Each consists of a latch Special Function Registers P0 through P3an output driver, and microcontroller input buffer. There are two different memory types: Most of the ports of the 89S52 have ‘dual function’ meaning that they can be used for two different functions. Telecommunication and Electronics Projects.

Those ports can be used to output DATA and orders do other devices, or to read the state of a sensor, or a switch. 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 mjcrocontroller is written between brackets.

Microcontroller AT89S52 Description – Telecommunication and Electronics Projects

In this application, Port 0 outputs the low byte of the external memory address, time-multiplexed with the byte being written or read. 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.

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’.

Otherwise the port pin is stuck at 0. 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.

This microcomputer – or microprocessor -related article is a stub. Port 2 outputs the high byte of the external memory address when the address is 16 bits wide. The alternate functions can only be activated if the corresponding bit latch in the port SFR contains a 1.

The output drivers of Ports 0 microcontroler 2, and the input buffers of Port 0, are used in accesses to external memory. Convert to Blogger by SimplexDesign. It has less complex feature than other microprocessor.
