What is a 8085 microprocessor?
The Intel 8085 is an 8-bit microprocessor introduced by Intel in 1976. It's an enhanced version of the 8080 microprocessor, with additional features and improvements. Key Features: 1.8-bit architecture: Processes 8-bit data. 2.Clock speed: Operates at a clock speed of 3.072 MHz or 4.77 MHz. 3. Instruction set: Supports 78 instructions, including arithmetic, logical, and control instructions. 4. Memory: Can address up to 64 KB of memory. 5. I/O: Provides 40 pins for input/output operations. Applications: Embedded systems: Used in various embedded systems, such as traffic lights, robots, and industrial control systems. Computers: Used in early personal computers, such as the TRS-80 and Sinclair ZX80. Microcontrollers: Served as a precursor to modern microcontrollers. Importance: Influence on modern microprocessors: The 8085's architecture and instruction set influenced the design of later microprocessors. Educational significance: The 8085 is still used in educational institutions to teach microprocessor architecture and programming. The Intel 8085 microprocessor played a significant role in the development of modern computing and remains an important part of computer history.
How to control speed of dc motor using microprocessor 8085?
Here the DC motor is controlled by the microprocessor (8085). The kit used was dynalog 8085 kit. The DC motor is very difficult to control unlike the stepper motor, which can be controlled by giving the appropriate CONTROL WORD. By knowing the DC motor theory we know the different methods used to control the motor, the most primitive and the once upon a time the most popularly method was WARDLEONARD motor speed control, but this had many disadvantage, so the world of Electronics brought in the thyristor control, which were very flexible and can be employed to use AC instead of DC cause they had a inbuilt convertor. The thyristor-based system is good but when used with Microprocessor based speed controller they are really good. We have shown the block diagram, circuit diagram used by us to control a small tape recorder sized motor
How many machine cycles do ADD and LHLD instructions have?
In the context of the 8085 microprocessor, the ADD instruction takes 1 machine cycle to execute, as it operates directly on the accumulator and the specified register. On the other hand, the LHLD (Load H and L Direct) instruction requires 3 machine cycles, as it involves reading data from a specified memory address into the L and H registers.
How many bits are in a char short and long on the Motorola 68000 microprocessor?
8, 16, 32
How many times the given loop will be executed 8085?
To determine how many times a loop in 8085 assembly language will execute, you need to analyze the loop's structure and the conditions that control it. Typically, this involves examining the instructions that modify a counter or a condition flag. For a precise answer, the actual code of the loop is required, as the execution count can vary based on the initial values and logic used in the loop.
How many memory location can be addressed by microprocessor 8085?
The 8085 can address 216, or 65536 different memory locations.
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?
One.
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?

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 are contained in the A register of a 8085 CPU?
8085 is a 8 bit microprocessor and so A register which is also known as accumulator is also 8 bit.
How many input output devices can the 8085 microprocessor access?
(00-FF) 256 devices!
Why 8085 microprocessor called accumulator based?
The 8085 microprocessor is often referred to as accumulator-based because it primarily uses an accumulator register (register A) for arithmetic and logic operations. Most instructions directly operate on the data stored in the accumulator, which acts as the primary register for processing. This design simplifies the architecture and instruction set, allowing for faster data manipulation since the accumulator can be quickly accessed. Additionally, many instructions involve loading data into the accumulator, performing operations, and then storing the results back, emphasizing its central role in the microprocessor's operation.
What is meaning of 8085 microprocessor?
8085 is a 8 bit microprocessor designed by Intel.
How many total instructions are there in 8085 MP?
there are 74 instruction sets in the 8085 up which consist of 246 bit pattern.
