AT89C51 is an 8-bit microcontroller and belongs to Atmel’s family. It can be erased and program to a maximum of times.

All these ports are 8-bit bi-directional ports, i. Except P 0 which needs external pull-ups, rest of the ports have internal pull-ups.

When 1s are written to these port pins, they are pulled high by the internal pull-ups and can be used as inputs. These ports are also bit addressable and so their bits can also be accessed individually. This high-density System-in-Package SiP integrates controller, power switches, and support components.
