The total time required to fetch and execute an instruction.
Adds 24 parallel I/O lines to interface with keyboards, LEDs, and alphanumeric displays.
: Differentiates between I/O operations (High) and memory operations (Low). S0cap S sub 0 S1cap S sub 1
Many educators and self-taught engineers search for a comprehensive "8085 microprocessor PPT by Gaonkar free" to streamline their lectures or self-study modules. This article synthesizes the core chapters, architectural diagrams, and programming paradigms popularized by Gaonkar into a structured, highly scannable reference guide. 1. Architectural Overview of the 8085
An 8-bit register that is part of the Arithmetic Logic Unit (ALU). It holds one of the operands for arithmetic/logic operations and stores the final result. microprocessor 8085 ppt by gaonkar free
. His teaching methodology is a staple in engineering curricula because it simplifies the transition from hardware architecture to software execution. Key Concepts in Gaonkar’s 8085 Teaching
The lowest priority interrupt. It is a general, maskable interrupt line. When activated, the microprocessor relies on an external device to place an opcode instruction (typically RST 0 through RST 7 or CALL ) onto the data bus.

This routine pulls two values from designated memory slots, adds them together, and saves the final output back to a designated memory location.
A high pulse on ALE signals external hardware (like a 74LS373 latch) to save the lower address bits, de-multiplexing the bus. Higher Address Bus (

Rahul's passion for the 8085 led him to create a comprehensive presentation on the microprocessor, which he generously shared with the world as a free PPT (PowerPoint Presentation) titled "Microprocessor 8085." The PPT quickly became a popular resource among students, engineers, and hobbyists, providing an in-depth look at the 8085's architecture, programming, and applications.
A 16-bit register pointing to the current memory address of the Last-In, First-Out (LIFO) stack structure implementation in the RAM. Slide 5: The Status Flag Register Slide Title: The 8085 Flags Register
Built using High-density NMOS (Negative-channel Metal-Oxide Semiconductor) technology. 2. Internal Architecture of the 8085
