How to calculate baud rate in 8051 microcontroller. Kds crystals datasheet, cross reference, circuit and application notes in pdf format. This is often accomplished via nested loops of known length and then including any extra loop setup and possibly subroutine call and return instructions. The 8051 microcontroller transfers and receives data serially at many different baud rates. The top countries of suppliers are china, taiwan, china, from which the percentage of 11. By the way original 8051s executed a single machine cycle every 12 clocks, so at 12 mhz, the instruction execution frequency was 1 million instructions per second. Crystal oscillators can be manufactured for oscillation over a wide range of frequencies, from a few kilohertz up to several hundred megahertz.
Lets find the time period of the machine cycle in each case for the following crystal frequency of different 8051 based systems. So to calculate the machine cycle, we take 112 of the crystal frequency, then take the inverse of it results in time period.
