Each MCU has its own advantage and disadvantage. Port P 0 and P 2 are also used to provide low byte and high byte addresses, respectively, when connected to an external memory. Their collection has just piled up after Microchip has acquired Atmel. Write to external data memory. Input receiver for serial communication. TL — Programmable Reference Voltage. Skip to main content. Submitted by webmaster on 14 May Choosing Motor For Robots. It is a 40 pin IC package with 4Kb flash memory.

These ports are also bit addressable and so their bits can also be accessed individually. But, since the AT89C51 has a strong community support if your motive is to learn embedded then AT89C51 can still be a good choice. Virgin Galactic — Commercial Space Flight.
