An 8-bit register containing 5 active status flags updated after ALU operations:
An 8-bit, NMOS microprocessor housed in a 40-pin Dual In-line Package (DIP).

Interrupts are external or internal signals that force the microprocessor to suspend its current program and execute a dedicated routine called an . The 8085 supports 5 hardware interrupts prioritized as follows: Interrupt Name Trigger Mechanism Vector Address 1 (Highest) TRAP Edge & Level Sensitive Non-Maskable RST 7.5 Rising Edge Sensitive RST 6.5 Level Sensitive RST 5.5 Level Sensitive 5 (Lowest) INTR Level Sensitive Non-Vectored

This unit acts as the brain of the microprocessor. It synchronizes all CPU operations with the clock frequency and generates control signals necessary for communication between the microprocessor and peripherals. 3. Pin Diagram and Signal Configuration

The Intel 8085 is a landmark in the history of computing. For students and engineers, Ramesh Gaonkar’s textbook "Microprocessor Architecture, Programming, and Applications with the 8085" remains the gold standard. If you are looking for a comprehensive microprocessor 8085 PPT based on Gaonkar’s methodology, this guide breaks down the core concepts you need for your presentation.
A signature element of Gaonkar’s teaching style is visual clarification of bus timings. A good PPT must include:
A 16-bit register pointing to the current top location of the Stack memory area (a Last-In, First-Out memory structure). B. Arithmetic and Logic Unit (ALU) The ALU performs real computing tasks, including: Addition and Subtraction Logical AND, OR, XOR, and Complement Left and Right Bit Shifts
