The 8085 is housed in a 40-pin DIP package. Understanding these pins is crucial for interfacing. Address and Data Bus
Slide 3: Functional Block Diagram (The Core of Gaonkar's Approach) 8085 Functional Architecture
The data is explicitly specified within the instruction itself (e.g., MVI A, 05H ).
The 8085 contains five 1-bit flip-flops that change states based on the results of ALU operations: microprocessor 8085 ppt by gaonkar
Set to 1 if the result contains an even number of 1s.

Before the era of ARM and RISC-V architectures, the Intel 8085 was the teaching standard. Gaonkar didn't just write a datasheet; he wrote a pedagogical masterpiece. Here is why his specific interpretation is so sought after for PowerPoint presentations: The 8085 is housed in a 40-pin DIP package
is widely considered the gold standard for introductory material on 8-bit architecture, mirroring the comprehensive depth of his classic textbook,
Altering the sequence of program execution conditionally or unconditionally (e.g., JMP , JC , CALL , RET ).
Interrupts allow the processor to respond to an asynchronous external event. The 8085 has five hardware interrupts, ordered by priority: (Highest Priority, Non-Maskable) RST 7.5 (Maskable) RST 6.5 (Maskable) RST 5.5 (Maskable) INTR (Lowest Priority, Maskable) The 8085 contains five 1-bit flip-flops that change
Vectored interrupts automatically point the Program Counter to a hardcoded, specific memory address inside memory. Slide 12: Memory and I/O Interfacing Slide Title: Connecting the 8085 to the Outside World
The instructions are the "language" of the processor. Gaonkar classifies them into functional categories. Data Transfer Instructions
