What is 8085a 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.
What is programming of microprocessor?
Microprocessors are typically programmed using semi-English-language statements (assembly language). These instructions are called the microprocessor’s instruction set. Programs in assembly and high-level languages are represented by instructions that use English-language-type statements.
What is true microprocessor?
What is true about microprocessor? C. It also communicate with the other devices connected to it. Explanation: Microprocessor is a controlling unit of a micro-computer, fabricated on a small chip capable of performing ALU (Arithmetic Logical Unit) operations and communicating with the other devices connected to it.
Is 8085 still used?
This capability matched that of the competing Z80, a popular 8080-derived CPU introduced the year before. These processors could be used in computers running the CP/M operating system. The 8085 is supplied in a 40-pin DIP package….Intel 8085.

What are the 3 most important parts of a microprocessor?
Microprocessor Components
- CPU.
- Bus.
- Memory.
What are the features of 8086 microprocessor?
1) The 8086 is a 16-bit microprocessor. The term “16-bit” means that its arithmetic logic unit, internal registers and most of its instructions are designed to work with 16-bit binary words. 2) The 8086 has a 16-bit data bus, so it can read data from or write data to memory and ports either 16 bits or 8 bits at a time.
Where is 8086 microprocessor used?
Intel 8086 microprocessor is the enhanced version of Intel 8085 microprocessor. It was designed by Intel in 1976. The 8086 microprocessor is a16-bit, N-channel, HMOS microprocessor. Where the HMOS is used for “High-speed Metal Oxide Semiconductor”.
What is the internal architecture of the 8085 microprocessor?
1. Internal Architecture of 8085 Microprocessor Control Unit Generates signals within uP to carry out the instruction, which has been decoded. In reality causes certain connections between blocks of the uP to be opened or closed, so that data goes where it is required, and so that ALU operations occur.
How many registers are there in the 8085 processor?
There are 6 general purpose registers in 8085 processor, i.e. B, C, D, E, H & L. Each register can hold 8-bit data. These registers can work in pair to hold 16-bit data and their pairing combination is like B-C, D-E & H-L.
What is the clock speed of the 8085a?
The 8085A is a complete 8 bit parallel central processor. It requires a single +5 volt supply. Its basic clock speed is 3 MHz thus improving on the present 8080’s performance with higher system speed. Also it is designed to fit into a minimum system of three IC’s: The CPU, a RAM/ IO, and a ROM or PROM/IO chip.
How to call a subroutine in an 8085 environment?
A portion of the main program to call a subroutine SUB in an 8085 environment is given below. It is desired that control be returned to LP+DISP+3 when the RET instruction is executed in the subroutine. The set of instructions that precede the RET instruction in the subroutine are
