It works with the popular 8051 architecture and hence is used by most beginners till date.It has four ports and all together provide 32 Programmable GPIO pins.It does not have in-built ADC module and supports only USART communication.But, since the AT89C51 has a strong community support if your motive is to learn embedded then AT89C51 can still be a good choice.
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. A compiler, where our program gets converted into MCU readable form called HEX files. Komunikasi Serial Mikrokontroler At89C51 Software Before TryingAlso simulating you program on software before trying it on hardware will save a lot of time. So you can use software like ISIS proteus from Labcenter to simulate your programs. Their collection has just piled up after Microchip has acquired Atmel. There are many parameters that one has to consider before selecting a MCU for hisher project. The below points are just suggestions which might help one to select a MCU. For example is you are reading many Analog voltages then make sure MCU has enough ADC channels and supportive resolution. Some MCU can support more than one module of the same protocol.
