Introduction The Intel 8085 is an 8-bit microprocessor introduced in the mid-1970s. R. Gaonkar’s widely used textbook and accompanying lecture PPTs present the 8085 architecture, instruction set, programming model, timing, and interfacing fundamentals in a clear, course-focused way. This article summarizes core topics a student or instructor would expect from “8085 PPT by Gaonkar.”

Functional Block Diagram (Visual schematic of the internal layout)

The 8085 microprocessor has several key features that make it a popular choice for many applications. Some of these features include:

Interrupts are hardware- or software-driven signals that temporarily suspend the microprocessor’s current program execution loop to service a priority routine known as an . Programming the 8085 Introduction The Intel 8085 is

The 8085 packaging consists of 40 operational pins categorized into functional groups:

Addressing modes describe how the microprocessor identifies the location of the operand required by an instruction.

Writes data bytes to a specified memory address. This article summarizes core topics a student or

These operations perform mathematical calculations, automatically updating the status flags based on the output.
