Before we dive into the PPTs, let's address the obvious: The Intel 8085 is an 8-bit processor from the late 1970s. Why do we still study it? microprocessor 8085 ppt by gaonkar free
The 8085 is an 8-bit, N-channel Metal Oxide Semiconductor (NMOS) microprocessor. It is famously used to teach the fundamentals of computer architecture because of its clear design. 8085 microprocessor ramesh gaonkar | PDF - Slideshare
The 8085 contains six 8-bit general-purpose registers: . They can be used individually or paired together ( BC, DE, HL ) to function as 16-bit registers. The HL pair acts as a memory pointer in many operations. The Accumulator (A Register)

Expands the single INTR line to accommodate up to eight vectored interrupts with dynamic priority ranking.
** pedagogical Clarity in Programming** Beyond hardware architecture, the 8085 is critical for teaching assembly language programming. Gaonkar’s materials are renowned for their step-by-step approach to instruction sets. The PPTs often categorize instructions into data transfer, arithmetic, logical, and branching groups, providing a logical taxonomy that aids retention. For a novice, the transition from high-level languages like Python or C to low-level assembly is jarring. Gaonkar’s slides mitigate this by using clear examples, such as the classic "Addition of Two 8-bit Numbers," to demonstrate how mnemonics translate to machine code and how that code manipulates flags in the status register. This specific focus on the "how" and "why" of programming fosters a deeper understanding of software-hardware interaction that high-level languages often abstract away. Explains how the lower-order address bus ( )
The Intel 8085 is a landmark in the history of computing. For students and engineers, Ramesh Gaonkar’s textbook "Microprocessor Architecture, Programming, and Applications with the 8085" remains the gold standard. If you are looking for a comprehensive microprocessor 8085 PPT based on Gaonkar’s methodology, this guide breaks down the core concepts you need for your presentation.
Moving data between registers, memory, and I/O (e.g., MOV , MVI , LDA , STA ).
Operates at a standard frequency of 3 MHz (crystal frequency of 6 MHz). Address Capacity: 16-bit address bus allows it to access bytes (64 KB) of memory. Module 2: Hardware Architecture and Pin Diagram Slide 3: Functional Block Diagram
Look for NPTEL or university course pages (like IIT or MIT OpenCourseWare), which often provide PDF/PPT versions of these lectures for free.
