The data operand is provided directly within the instruction itself (e.g., MVI A, 32H ).
Altering the sequence of program execution conditionally or unconditionally (e.g., JMP , JC , CALL , RET ).
A well-constructed 8085 PPT based on Gaonkar’s framework follows a predictable yet powerful narrative arc, typically comprising 60–120 slides. It is a blueprint of a revolution, broken down into discrete modules:
Lowest priority, non-vectored, maskable interrupt requiring an external hardware device to supply an opcode instruction byte (usually RST or CALL ).
The reason “Gaonkar” is so closely linked to the 8085 is that his book provides the definitive roadmap for understanding this processor. It is structured to take a learner from ground zero to a high level of proficiency. A standard course using Gaonkar's textbook is typically structured week-by-week, which is directly mirrored in the PPTs. microprocessor 8085 ppt by gaonkar

(Write): A low-active signal indicating that data on the data bus is to be written into the selected memory or I/O location. Status Pins (
: Typically runs at a maximum frequency of 3 MHz . Power Requirement : Operates on a single +5V DC supply.
Features a built-in clock generator and system controller, reducing the need for external support chips. Slide 2: The Gaonkar Pedagogical Approach The data operand is provided directly within the
The 8085 is an NMOS (Negative-channel Metal-Oxide Semiconductor) microprocessor introduced by Intel in 1976. It is an enhanced version of its predecessor, the 8080, designed to require fewer support chips to function.
You're looking for an informative post on "Microprocessor 8085 PPT by Gaonkar". Here's what I found:
Copies data from a source to a destination without modifying it (e.g., MOV , MVI , LXI , LDA ).
The time required to complete one access operation of memory or an I/O device (typically 3 to 6 T-states). It is a blueprint of a revolution, broken
: Moving data between registers or memory (e.g., MOV , MVI ).
A 16-bit register that points to the top of the stack in RAM.

In your diagrams, use one color for the Address Bus and another for the Data Bus .
The primary 8-bit register used to store data during ALU operations and receive the final result.
