Microprocessors and Microcontrollers is an established textbook for engineering students pursuing a course in electrical and electronics, electronics and communication, computer science, and information technology. It is also a useful resource for practising professionals. This second edition of the book goes one step further in providing a comprehensive coverage of topics and an application-oriented approach. The book is divided into six parts that cover the architecture, programming, and interfacing of 8085 and 8086 microprocessors, and 8096 and 8051 microcontrollers. Its lucid explanation and strong learning features such as case studies, design-based exercises, review questions, and assembly language programming examples lay a solid foundation for the subject. The additional C language programs for the 8051 microcontroller enhance the spectrum of coverage of the book.
