The 8051 family of microprocessors are the universally accepted standard which all electronics undergraduates need to know about. Students with only an elementary understanding of microprocessors will find this text especially useful. '8051 Microcontrollers' provides a practical and readable description of the 8051 family of microcontrollers, including 16-bit devices, and their use in practical applications. Often students and technicians are reliant on manufacturers' data books and application manuals to learn about these ubiquitous devices. This book fulfils the need for an easily understood account of the subject and uses worked examples, real-life applications, summary sections and exercises to demonstrate the relevance of the theory to everyday domestic and commercial situations.
