What are the limitations of 8085 microprocessor?
8085 Microprocessor has multiplexed address and data bus, so extra hardware is required to separate address and the data signals. Flags are very limited in 8085. Interrupts are very limited in 8085. Operating frequency is less in 8085 microprocessor, so the speed of execution is slow.
What is the major difference between Intel 8080 and 8086?
The 8086 design was expanded to support full 16-bit processing, instead of the fairly basic 16-bit capabilities of the 8080/8085. New kinds of instructions were added as well; full support for signed integers, base+offset addressing, and self-repeating operations.

What are the advantages and limitations of the microprocessor controlled system?
The microprocessor has a limitation on the size of data. Most of the microprocessor does not support floating point operations. The main disadvantage is it’s over heating physically. It should not contact with the other external devices.
What are the advantages and disadvantages of microcontroller and microprocessor?
The microcontroller is easy to interface additional RAM, ROM, and I/O port. Once microcontroller is programmed then they cannot be reprogrammed. Without any digital parts, it can act as microcomputer. It is easy to use, troubleshooting and system maintaining is simple.
What is the use of microprocessor 8085?
8085 is pronounced as “eighty-eighty-five” microprocessor. It is an 8-bit microprocessor designed by Intel in 1977 using NMOS technology. It is used in washing machines, microwave ovens, mobile phones, etc.
What is the difference between 8080 microprocessor and 8085 microprocessor?
Intel 8080 Microprocessor was released on April 1974 and Intel 8085 Microprocessor was introduced in 1976. 8085 is very close to the 8080 microprocessor, but some slight changes and modifications are present. There is 8 dedicated pins are there as Data bus (D0 to D7).
What are the limitations of 8-bit microprocessors?
Now micro processors with 8 bit are not available (at least commercially). 16 bit micro processors are also obsolete. Limitations of 8080 and 8085 are just that they are old and so inefficient now. Explore macroeconomics online with MIT.
What is the configuration of 808085?
8085 is pronounced as “eighty-eighty-five” microprocessor. It is an 8-bit microprocessor designed by Intel in 1977 using NMOS technology. It has the following configuration −. 8-bit data bus; 16-bit address bus, which can address upto 64KB; A 16-bit program counter; A 16-bit stack pointer; Six 8-bit registers arranged in pairs: BC, DE, HL
What is the address bus size of 8085 microcontroller?
The address bus is of 16 bits. The address bus is of 20 bits. The memory capacity is 64 KB.Also 8085 Can Perform Operation Upto 2^8 ie. 256 numbers. A number greater than this is to taken multiple times in 8 bit data bus.
