Is 8085 a microcontroller chip?
The multiplexed address/data bus reduced the number of PCB tracks between the 8085 and such memory and I/O chips. The 8085 had a long life as a controller, no doubt thanks to its built-in serial I/O and five prioritized interrupts, arguably microcontroller-like features that the Z80 CPU did not have.
What is the 8085 microprocessor?
The 8085 microprocessor is an 8-bit processor that includes on its chip most of the logic circuitry for performing computing tasks and for communicating with peripherals.
Is the 8085 still used?
The Intel 8085 microprocessor was introduced 40 years back, and along with its contemporaries — the Z80 and the 6502 — is pretty much a dinosaur in terms of microprocessor history. But that doesn’t stop it from still being included in the syllabus for computer engineering students in many parts of the world.
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.
Is 8085 a RISC or CISC?
So we can say our processor 8085 is a RISC and controller 8051 is a CISC. Reduced instruction set Computer. It is a type of microprocessor that has been designed to carry out few instructions at the same time. As instruction are few it can be executed in a less amount of time.
What are the features of 8085?
The features of 8085 include:
- It is an 8-bit microprocessor i.e. it can accept, process or provide 8-bit data.
- It operates on a single +5V power supply connected at Vcc.
- It operates on clock cycle with 50% duly cycle.
- It has on chip clock generator this internal clock generator requires tuned circuit like LC,
What are instructions of 8085?

Which type of architecture 8085 has?
Both data and program are in the same memory. So, Von Neumann architecture or Princeton architecture.
What is the clock speed of 8085 microprocessor?
8085 operates on a clock frequency of 3MHz–6MHz depending upon the version selected. Clock is provided by a crystal oscillator of 2 times the frequency, so as to produce a 50% duty cycle clock. The minimum operating frequency of 8085 is 500kHz.
What are the main features of 8085 microprocessor?
Features of 8085 Microprocessor:
- 1.It is an 8-bit microprocessor i.e. it can accept, process, or provide 8-bit data simultaneously.
- 2.It operates on a single +5V power supply connected at Vcc; power supply ground is connected to Vss.
- 3.It operates on clock cycle with 50% duty cycle.
- 4.It has on chip clock generator.
How many bits are used in the data bus of 8085?
8 bits
Data bus: Length of the data bus is 8 bits. This bus is used to transfer data between microprocessor and memory or IO devices in both directions.
How many buses are there in 8085 microprocessor?
three buses
8085 System Bus: Microprocessor communicates with memory and other devices (input and output) using three buses: Address Bus, Data Bus and Control Bus.
What are the features of a 8088 microprocessor?
The 8088 microprocessor has 16-bit registers, 16-bit internal data bus and 20-bit address bus, which allows the processor address up to 1 MB of memory. The 8088 uses the same segmented memory addressing as the 8086: the processor can address 64 KB of memory directly, and to address more
What is the speed of 8088?
The Intel 8088 has a clock speed from 5-10 MHz, with 16-bit registers, a 20-bit address bus, a 16-bit external data bus, and supports 1 mb of memory. The Intel 8088 also supports the Intel 8087 numeric co-processor that enables it to recognize and process floating point data and instructions.
What is the Intel 8088?
The Intel 8088 is a type of microprocessor that is part of the Intel 8086 series of microprocessors.
What is the history of microprocessor?
The first use of the term “microprocessor” is attributed to Viatron Computer Systems describing the custom integrated circuit used in their System 21 small computer system announced in 1968.
