Detailed explanation-1: -Internally 8085A works with a frequency of 3 MHz internally with clock frequency. Hence a crystal of frequency of 6-MHz crystal gets connected between X1 and X2. Every operation in the entire 8085 system occurs with the given synchronization process with the clock.
Detailed explanation-2: -The 8085 microprocessor has an on-chip oscillator of 3 MHz. The 8086 microprocessor is available in three version with a clock speed (frequency) of 5 MHz, 8 MHz and 10 MHz. The 8085 microprocessor consists of 6500 transistors in its structure. The 8086 microprocessor consists of 29000 transistors.
Detailed explanation-3: -In 8085 microprocessor, why the frequency is internally divided by 2? The oscillations produced through the crystal are not uniform. They have a lot of distortion in the wave. To avoid such distortions that distorted wave is divided by 2 to get a uniform square clock pulse.
