MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -The Intel 8085 ("eighty-eighty-five") is an 8-bit microprocessor produced by Intel and introduced in March 1976. It is software-binary compatible with the more-famous Intel 8080 with only two minor instructions added to support its added interrupt and serial input/output features.

Detailed explanation-2: -Why 8085 processor is called an 8 bit processor? Because 8085 processor has 8 bit ALU (Arithmetic Logic Review). Similarly 8086 processor has 16 bit ALU.

Detailed explanation-3: -In 8085 microprocessor, Address bus is of 16 bits (A0-A15) and can transfer maximum 16 bit address and hence can address 65, 536 different memory locations. This bus is multiplexed with 8 bit data bus.

Detailed explanation-4: -8085 is pronounced as “eighty-eighty-five” microprocessor. It is an 8-bit microprocessor designed by Intel in 1977 using NMOS technology.

Detailed explanation-5: -8 bit microprocessor:-8-bit is an early computer hardware device or software program that is capable of transferring eight bits of data at the same time. The Intel 8085 is an 8-bit microprocessor. Its data bus is 8-bit wide and hence, 8 bits of data can be transmitted in parallel from or to the microprocessor.
