The clock speed of the 8085 depends on the particular chip chosen. The basic 8085 could run up to around 3 MHz. The -1 version could run up to around 6 MHz. The -2 version could run up to around 5 MHz.
In each case, the crystal frequency had to be exactly twice the desired clock frequency, i.e. 6 Mhz, 12 MHz, and 10 MHz, respectively.
In all cases, the minimum clock frequency was 500 KHz. (Crystal 1 MHz)

There are 74 instructions in the 8085 microprocessor.
In 8085A microprocessor What is the meaning of A here?
Maximal clock speed. 8085: ? 8085A: 3 MHz 8085AH: 5 MHZ
What is the function of READY pin of 8085?
The READY pin on the 8085 microprocessor is used to delay the completion of a bus transfer cycle. It is sampled by the 8085 at the falling edge of clock following ALE. If it is high, the cycle completes. If it is low, the cycle is extended by one clock, with all lines held steady - then it is sampled again at each of the next falling edges of clock until it is high. The purpose of READY is to allow (usually) memory devices to operate at a slower speed than the 8085.

Specify the crystal frequency required for an 8085 system to operate at 1.1mhz?
The crystal frquency in an 8085 system is twice the desired clock frequency, so a crystal of 2.2 MHz is required to operate at 1.1 MHz.Note: Clock frequency is not the same as instructions per second, because the instructions in an 8085 take a variable number of clock cycles, between 4 and 18, to execute.
Why clock frequency of 6.14 mhz is used in 8085 microprocessor?
Because it is the top operating speed for that IC
How many clock cycles for halt in 8085?
7
Give the clock out frequency and state time T of 8085 when the crystal frequencies is 5MHz?
The clock out frequency of an 8085 is one half the crystal frequency. The period of one T cycle is the inverse of the clock frequency. At a crystal frequency of 5MHz, the clock is 2.5MHz, and T is 400 ns.
What is the difference between the Intel 8085 and the Intel 8086?
The Intel 8085 is an 8 bit microprocessor created in 1977.The Intel 8086 is a 16 bit microprocessor created in 1978. The 8086 was the first chip to start the x86 architecture family.8085 contains 16-bit address bus and 8-bit data bus8086 contains 20-bit address bus and 16-bit data bus..In 8085 the clock speed is 3MHZwhere as in 8086 the clock speed is 5MHZ.there are two differences btw 8085&80861. 8086 has 6 byte queue but 8085 has 4 byte queue2. 8086 has 16 bit data bus where as 8085 has 8 bit data bus
What no of instruction will be execute by using only one clock pulse in 8085 microprocessor?
There are no instructions in the 8085 that execute in only one clock pulse. The minimum number of clock cycles is four; three for instruction fetch and one for instruction decode/execute.
What is t state in 8085 microprocessor?
A T state is one cycle of the system clock.
When trap interrupt line is checked by 8085 microprocessor?
In the 8085, trap, intr, and rstx.5 lines are checked on the falling edge of clock, at the beginning of the last T cycle of an instruction, or approximately one clock cycle before ALE.
