It gives the possibility to generate several precise baudrates for serial communications. With 12 MHz you introduce small errors that will however be acceptable for hobbyists.


What is range of crystal oscillator frequency in ATMEL89C51?

Atmel posts the datasheet for their AT89C51 and other microcontrollers on their website (see link below). That datasheet specifies that the Atmel AT89C51 is operational for an oscillators in the range 24 MHz to 0 Hz (fully static paused). However, during initial flash programming and verification, it requires an oscillator frequency in the range 24 MHz to 3 MHz. That datasheet also answers many other questions you might have about this microcontroller.
