Microprocessor 8085 Ppt — By Gaonkar ^new^

Direct: 16-bit memory address is specified in the instruction (e.g., LDA 2050H ).

Eight instructions ( RST 0 through RST 7 ) that act as programmatic vector jumps. Slide 10: Interfacing and Peripheral Devices Slide Title: Peripheral Interfacing Concept Core Concepts:

Highest priority, non-maskable (cannot be disabled by software), vectored interrupt. Used for catastrophic events like power failures. RST 7.5: Maskable, vectored, edge-triggered interrupt. RST 6.5: Maskable, vectored, level-triggered interrupt. RST 5.5: Maskable, vectored, level-triggered interrupt.

The 8085 microprocessor has a total of 78 instructions, which are divided into the following categories: microprocessor 8085 ppt by gaonkar

: The final part of the course teaches students how to build a complete microprocessor system. Slides cover topics such as:

16-bit (can address 2¹⁶ = 65,536 bytes or 64KB of memory). Clock Speed: Typically 3MHz (requires a +5V power supply).

distinguishes between I/O operations (High) and Memory operations (Low). Combined with S1 and S2, they define the exact operational state (e.g., Opcode Fetch, Memory Read, Memory Write). Direct: 16-bit memory address is specified in the

High-performance Metal-Oxide-Semiconductor (HMOS) Integration: 40-pin Dual In-line Package (DIP) 2. Hardware Architecture and Functional Blocks

DMA (Direct Memory Access) Controller for high-speed data bypass directly to memory. Slide 11: Summary and Legacy Slide Title: Conclusion and the Legacy of the 8085 Core Concepts:

Set to 1 if an arithmetic operation generates a carry out of the most significant bit (D7). 3. Demultiplexing the Address and Data Bus Used for catastrophic events like power failures

Below is a structured outline for your PPT, incorporating key concepts and technical specifications found in Gaonkar’s curriculum.

Gaonkar emphasizes the relationship between the system clock and instruction execution.
