89C52 MICROCONTROLLER PDF

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. This allows a great amount of legacy code to be reused without modification in new applications. 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. Each consists of a latch Special Function Registers P0 through P3 , an output driver, and an input buffer. The output drivers of Ports 0 and 2, and the input buffers of Port 0, are used in accesses to external memory. In this application, Port 0 outputs the low byte of the external memory address, time-multiplexed with the byte being written or read.

Note: The datasheet of the AT89S52 Microcontroller and more detailed Features can be found at the bottom of this page. Since it is similar to the trust worthy architecture these microcontrollers are as per industry standard. The Microcontroller also has Operating mode, Idle Mode and Power down mode which makes it suitable for battery operated applications. However you can utilise external modules for the same. Atmel microcontroller can be programmed with different software's that is available in the market.

Arduino, Keil uVision are the most used platforms to name a few. If you are planning on serious programming and expansion with community support then Keil is recommended. In order to program the Atmel microcontroller we will need an IDE Integrated Development Environment , where the programming takes place. Also simulating you program on software before trying it on hardware will save a lot of time. Their collection has just piled up after Microchip has acquired Atmel. Each MCU has its own advantage and disadvantage.

The below points are just suggestions which might help one to select a MCU. Subscribe to stay updated with industry's latest Electronics components and news. Component Datasheet. AT89S52 Microcontroller Datasheet. Tags Microcontroller. Get Our Weekly Newsletter!
