This fully revised edition of Microcontrollers is based on the feedback received from users across the country. It prepares the students for system development using the 8051 as well as 68HC11, 80x96, ARM and PIC family microcontrollers. It provides a perfect blend of both hardware and software aspects of the subject. A key feature is the clear explanation of the use of the software building blocks, interrupt handling mechanism, timers, RTOS, IDE and interfacing circuits. It also covers aspects such as programming, interfacing and system design, and offers a large number of figures and tables, examples, end-chapter summaries, meanings of key terms, review questions, practice exercises, and multiple choice questions.
