There are 256 ports available in the 8085 microprocessor. The IN and OUT instructions have an 8-bit port number, and that is where the 256 comes from.
In order to use ports, the hardware addressing system must decode IO/M-. Some implementations don't do this, so they map IO addresses to memory addresses. In that case, you could say there are 65536 possible IO addresses, but that is not the same as ports, because ports are specific to the IN and OUT instructions.
The other "problem" with IN and OUT is that you cannot specify the address in a register, while you can do so with indirect memory addressing.

How many bits in 8085 microprocessor?
The 8085 is an 8-bit microprocessor. Even though there are some 16-bit registers (BC, DE, HL, SP, PC), with some 16-bit operations that can be performed on them, and a 16-bit address bus, the accumulator (A), the arithmetic logic unit (ALU), and the data bus are 8-bits in size, making the 8085 an 8-bit computer.
How many bits in 80286 processor?
8086 is a 16bit processor.
How many total instructions are there in 8085 MP?
there are 74 instruction sets in the 8085 up which consist of 246 bit pattern.
How many power supply uses in 8085 microprocessor?
+5v supply is alone needed for Intel 8085 Microprocessor
How many instruction are there in 8085 mp?
There are 74 instructions in the 8085 microprocessor.
How many ic does 8085 microprocessor have?

What are the uses of an Intel 8085 microprocessor?
In many engineering schools the 8085 processor is used in introductory microprocessor courses. Trainer kits composed of a printed circuit board, 8085, and supporting hardware are offered by various companies. These kits usually include complete documentation allowing a student to go from solder to assembly language programming in a single course..
How many location can be accessed by 8085 microprocessor?
The 8085 microprocessor can access 65536 (2^16) locations in memory, and 256 (2^8) locations in I/O space.
How many bit input is given to a microprocessor?
8 bit input is given to Intel 8085 microprocessor.
How many flags in microprocessor 8085 are issued by Intel?
5 FLAGS
How many data lines in 8086?
There are eight datalines, D0 through D7, in the 8085 microprocessor. They are shared, or multiplexed with the eight low order address lines, A0 through A7, and are called AD0 through AD7 on the pinout drawing.
What is the difference between 8080 and 8086?
The major difference between the 8085 and the 8086/8088 is that the 8085 is an 8 bit computer, and the 8086/8088 is a 16 bit computer.
