If you are looking to build or study a presentation using the principles outlined above, your slide deck should follow this sequential structure to match Ramesh Gaonkar’s pedagogy:
Ramesh S. Gaonkar’s textbook has long been a standard in engineering education, offering a clear, comprehensive approach to the subject. It provides an integrated treatment of both the hardware and software aspects of the microprocessor, using the 8085 family to teach the basic concepts underlying all programmable devices. It doesn't assume any programming background, making it accessible to beginners.
The microprocessor places the 16-bit address from the Program Counter onto the address buses. ALE goes high to latch the lower address. T2: The RD¯modified cap R cap D with bar above microprocessor 8085 ppt by gaonkar free

For students looking to download ready-made presentation files that directly adapt Ramesh Gaonkar's text, several educational databases provide free slide decks.
The 40 pins of the 8085 can be categorized into specific functional groupings based on their operational roles.

Moving data between registers, memory, and I/O (e.g., MOV , MVI , LDA , STA ).
Ramesh Gaonkar’s text is celebrated for its clear, step-by-step approach to understanding both the hardware architecture and software programming of the 8085. A PPT based on his book typically breaks down the complexities of the 8-bit processor into manageable units.
The first byte is the opcode; the second byte is an 8-bit data operand (e.g., MVI B, 05H ).
A 16-bit register pointing to the current memory location in the Stack area (Last-In, First-Out sequence). The Flags Register
