Provides reliable real-time external communication through 5 hardware interrupt pins arranged by strict priority levels.
Includes opcode and operand in a single byte (e.g., MOV A, B , ADD C ).

: The time required to complete one access operation (Memory Read, I/O Write, etc.). microprocessor 8085 ppt by gaonkar free
If you would like help with any specific area of the 8085 microprocessor to build out your presentation, let me know. I can easily generate , provide a deeper breakdown of addressing modes , or write out step-by-step descriptions for specific timing diagrams .
Performs addition, subtraction, increments, or decrements on data registers or memory blocks. (Examples: ADD , ADI , SUB , INR , DCR ).
Maskable, edge-triggered interrupt. Vectored to 003CH . If you would like help with any specific
One subdivision of a machine cycle corresponding to one clock period. Example: Opcode Fetch Cycle
Uses an intuitive design with standard 8-bit data processing and a 16-bit memory addressing limit (
: When writing Assembly language code examples on slides, use bolding for mnemonics ( MOV ) and standard text for operands ( A, B ). (Examples: ADD , ADI , SUB , INR , DCR )
: All components (CPU, RAM, ROM, I/O) integrated into a single silicon chip. Slide 2: Features of the Intel 8085 Architecture : 8-bit general-purpose microprocessor. Pin Configuration : 40-pin Dual In-line Package (DIP). Speed & Power
If you are looking for free presentations or notes that mirror Gaonkar's teaching style, you can find comprehensive materials on platforms like or academic repositories like Willingdon College .
-States: The subdivision of a machine cycle corresponding to one clock period. An Opcode Fetch cycle typically requires 4 -states, while a standard Memory Read requires 3 Module 5: Interrupts and Interfacing
