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.

Program pulse input during Flash programming. AT89C51 is an 8-bit microcontroller and belongs to Atmel’s family.

When 1s are written to these port pins, they are pulled high by the internal pull-ups and can be used as inputs. It works with the popular architecture and hence is used by most beginners till date.

Output transmitter for serial communication. Instead the new AT89S51 is recommended for new applications. Except P 0 which needs external pull-ups, rest of the ports have internal pull-ups. If you are planning on serious programming and expansion with community support then Keil is recommended. Low-order address bits when interfacing ratasheet external memory. The AT89C51 is an age old 8-bit microcontroller from the Atmel family. It can be programmed to operate at different baud rates.
