Used copies are abundant on Amazon, AbeBooks, and Flipkart. A new copy typically costs ₹550–₹700 in India ($25–$35 internationally). Many universities also provide PDF access through institutional library subscriptions, but the physical book is preferred for lab use.
: The principles of 8085 input/output (I/O) interfacing apply directly to modern microcontrollers like PIC, AVR (Arduino), and ARM Cortex-M processors. 🗺️ Core Architecture: Inside the 8085
Treating the microprocessor as a complex system of buses, latches, and timing signals.
Key devices analyzed include the , which expands the chip's physical I/O ports, and the Intel 8254 Programmable Interval Timer , used for precise frequency generation, delay management, and digital clock synchronization. Why Gaonkar's Approach Endures Used copies are abundant on Amazon, AbeBooks, and Flipkart
Performing bitwise Boolean logic, inversions, and comparisons (e.g., ANA , ORA , XRA , CMA , CMP ).
If you are self-studying, do not just read it. Follow this method:
For decades, Gaonkar's text has been widely regarded as a gold standard for learning the 8085 microprocessor. It is praised for its clarity, depth, and logical flow. The Thriftbooks User Review says: "A very comprehensive, good introductory text. I highly recommend this book to any instructor teaching an introductory microprocessor course. The 8085 is an excellent processor to start students in microprocessor theory." : The principles of 8085 input/output (I/O) interfacing
🔹 It doesn’t just teach theory; it dives into interfacing and practical applications that give students the logic needed to understand modern embedded systems.
: ~2,200 words. Optimized for the keyword phrase “R. Gaonkar microprocessor architecture programming and applications with the 8085 prentice hall 2014.”
Ramesh Gaonkar ’s Microprocessor Architecture, Programming, and Applications with the 8085 The 8085 offers a complete
AND, OR, XOR, and rotate instructions.
Another reviewer from Thriftbooks reinforces this, saying: "I had read this book page by page during the semester of Computer Architecture course in 1986, but it is even more useful today. Because the book explains every concept on microprocessor with the help of 8085 which is very simple to understand." On Flipkart, a user succinctly states: "This book provides a comprehensive treatment of the microprocessor, covering both hardware and software based on the 8085 Microprocessor family." The book continues to be cited in modern engineering courses as a key reference for microprocessor fundamentals.
: TRAP (non-maskable), RST 7.5, RST 6.5, RST 5.5, and INTR. Software Interrupts : RST 0 through RST 7.
Attempting to learn computer architecture via a modern x86 processor is counterproductive for a beginner due to hundreds of registers, complex caching layers, and pipeline architectures. The 8085 offers a complete, transparent, and graspable microcosm of computing logic. 6. Conclusion
The book is structured into three primary parts that move from basic concepts to complex system applications:
