PIC Microcontrollers: An Introduction to Microelectronics, Third Edition, provides an introduction to the complex technology of microcontrollers. Starting with the standard PC, it establishes basic concepts and terminology: microprocessor systems, memory, input and output, and general digital systems ideas. It then examines the PIC microcontroller (MCU), which dominates the market for small-scale industrial applications. The analysis includes a chip that is no longer used commercially, with the minimum of advanced features: the PIC 16F84A; and the PIC 16F690, which has more features and is representative of more recent products in the PIC range. The discussions cover PIC architecture, programming techniques, PIC development systems, application design, program debugging, PIC motor applications, and microcontroller systems. Each chapter begins with an outline of contents and concludes with a set of questions for self-assessment or formal testing of students. This book was written for beginners, college or university students, or independent hobbyists.
