It can be programmed to operate at different baud rates. Their collection has just piled up after Microchip has acquired Atmel. The AT89C51 is an age old 8-bit microcontroller from the Atmel family. Choosing Battery for Robots.

AT89C51 Microcontroller

Low-order address bits when interfacing with external memory. But, since the AT89C51 has a strong community support if your motive is to learn embedded then AT89C51 can still be a good choice.


Input receiver for serial communication. These ports are also bit addressable and so their bits can also be accessed individually. High-order address bits when interfacing with external memory.

All these ports are 8-bit bi-directional ports, microcontrollwr. What is Web Browser.

ATMEL 89C51 | AT89C51 Microcontroller Pin Diagram & Description

Supply datasheeet 5V up to 6. Read from external data memory. In order to program the Atmel microcontroller we will need an IDE Integrated Development Environmentwhere the programming takes place. Also simulating you program on software before trying it on hardware will save a lot of time. The AT89C51 is no longer in production and Atmel does not support new design. It is a 40 pin IC package with 4Kb flash memory.

This high-density System-in-Package SiP integrates controller, power switches, and support components.
