The CPU automatically branches to a pre-defined, fixed memory address upon receiving the signal.

Applications of the 8085 Microprocessor Although older, the 8085 teaches the principles of: Traffic Light Control Systems Temperature Controllers Stepper Motor Control Electronic Instrumentation Conclusion
: It is a 40-pin IC that operates on a +5V power supply at a maximum frequency of 3 MHz. Instruction Set microprocessor 8085 ppt by gaonkar free
Performs arithmetic (8-bit addition, subtraction) and logical operations (AND, OR, XOR).
A positive-going pulse used to latch the lower 8 bits of the address during the first clock cycle of a machine cycle. Control and Status Signals: RD¯modified cap R cap D with bar above (Read): Low active signal indicating memory or I/O read. WR¯modified cap W cap R with bar above (Write): Low active signal indicating memory or I/O write. : High for I/O operations; Low for Memory operations. The CPU automatically branches to a pre-defined, fixed
You can find comprehensive presentation slides and summaries based on Gaonkar’s work through these educational platforms:
The 8085 has five hardware interrupts: TRAP (highest priority), RST 7.5, RST 6.5, RST 5.5, INTR. 4. 8085 Instruction Set and Addressing Modes Gaonkar classifies 8085 instructions into five groups: Data Transfer Group: Moves data (e.g., MOV, MVI, LDA, STA). Arithmetic Group: Performs math (e.g., ADD, SUB, INR, DCR). Logical Group: Bit manipulation (e.g., ANA, ORA, XRA, CMP). Branching Group: Jumps and calls (e.g., JMP, CALL, RET). Machine Control Group: Affects CPU status (e.g., HLT, NOP). Addressing Modes refer to how the operand is specified: Immediate, Register, Direct, Indirect, and Implicit. 5.

The 8085 microprocessor remains a foundational subject in computer engineering and electronics. Whether you are a student preparing for exams or an educator designing a curriculum, finding quality, structured study materials is crucial. seminal book, Microprocessor Architecture, Programming, and Applications with the 8085 , is considered the "bible" for this subject.
To build a highly effective presentation that aligns with Gaonkar's teaching structure, divide your slides into four primary pillars: Pillar 1: Hardware Architecture & Pin Diagram
, you can utilize the following structured information and download resources. Report & Presentation Summary
Alter the normal sequential flow of execution based on specific conditions (or unconditionally). JMP address (Unconditional Jump) JC address (Jump if Carry flag is set) CALL address (Call a subroutine) RET (Return from subroutine) Machine Control Instructions Control state configurations and interrupt lines. NOP (No Operation—creates processing delays) HLT (Halt CPU execution) SIM / RIM (Set/Read Interrupt Masks) 4. Timing Diagrams and Machine Cycles
