A textbook for a wide range of introductory courses in FE and HE. Provides an introduction to microprocessors, assuming no previous knowledge or a technical or mathematical background. All technical terms are carefully introduced and difficult subjects are clearly explained.
Primarily intended for diploma, undergraduate and postgraduate students of electronics, electrical, mechanical, information technology and computer engineering, this book offers an introduction to microprocessors and microcontrollers. The book is designed to explain basic concepts underlying programmable devices and their interfacing. It provides complete knowledge of the Intel’s 8085 and 8086 microprocessors and 8051 microcontroller, their architecture, programming and concepts of interfacing of memory, IO devices and programmable chips. The text has been organized in such a manner that a student can understand and get well-acquainted with the subject, independent of other reference books and Internet sources. It is of greater use even for the AMIE and IETE students—those who do not have the facility of classroom teaching and laboratory practice. The book presents an integrated treatment of the hardware and software aspects of the 8085 and 8086 microprocessors and 8051 microcontroller. Elaborated programming, solved examples on typical interfacing problems, and a useful set of exercise problems in each chapter serve as distinguishing features of the book.
The book is written for an undergraduate course on the 8085 and 8086 microprocessors and 8051 microcontroller. It provides comprehensive coverage of the hardware and software aspects of 8085 and 8086 microprocessors and 8051 microcontroller. The book uses plain and lucid language to explain each topic. A large number of programming examples is the feature of this book. The book provides the logical method of describing the various complicated concepts and stepwise techniques for easy understanding, making the subject more interesting. The book is divided into three parts. The first part focuses on the 8085 microprocessor. It teaches you the 8085 architecture, pin description, bus organization, instruction set, addressing modes, instruction formats, Assembly Language Programming (ALP), instruction timing diagrams, interrupts and interfacing 8085 with support chips, memory and peripheral ICs - 8251, 8253, 8255, 8259 and 8279. It also explains the interfacing of 8085 with data converters - ADC and DAC- and introduces a temperature control system design. The second part focuses on the 8086 microprocessor. It teaches you the 8086 architecture, register organization, memory segmentation, interrupts, addressing modes, operating modes - minimum and maximum modes, interfacing 8086 with support chips, minimum and maximum mode 8086 systems and timings. The third part focuses on the 8051 microcontroller. It teaches you the 8051 architecture, pin description, instruction set, programming 8051 and interfacing 8051 with external memory. It explains timers/counters, serial port, interrupts of 8051 and their programming. It also describes the interfacing 8051 with keyboards, LCDs and LEDs and explains the control of servomotor, stepper motors and washing machine using 8051.
The book begins with bipolar and unipolar logic families. It teaches you the TTL and CMOS logic families. It provides in-depth information about analog to digital converters and digital to analog converters. It also covers semiconductor memories and programmable logic devices. Then the book introduces microprocessors and microcontrollers. It introduces microprocessor with basic concepts, terminologies, phases in the execution process, evolution, block diagram, programming, instruction format, addressing modes, architectural advancements, selection criteria and applications. It also explains the block diagram, various types and applications of the microcontrollers. Finally, the book incorporates a detailed discussion of display devices.
Assuming only a general science education this book introduces the workings of the microprocessor, its applications, and programming in assembler and high level languages such as C and Java. Practical work and knowledge-check questions contribute to building a thorough understanding with a practical focus. The book concludes with a step-by-step walk through a project based on the PIC microcontroller. The concise but clearly written text makes this an ideal book for electronics and IT students and a wide range of technicians and engineers, including IT systems support staff, and maintenance / service engineers.*Crisp's conversational style introduces the fundamentals of the micro (microprocessors, microcontrollers, systems on a chip) in a way that is utterly painless but technically spot-on: the talent of a true teacher.*Microprocessors and microcontrollers are covered in one book, reflecting the importance of embedded systems in today's computerised world.*Practical work and knowledge-check questions support a lively text to build a firm understanding of the subject.
The 8085 is a microprocessor that has 8 bits and is made using N-MOS technology. It features 16-bit address bus and consequently can address up to 216 = 65536 bytes (64KB) memory addresses via A0-A15. AD0–AD7 are multiplexed over the first eight lines of the address bus and the first eight lines of the data bus, respectively. The eight lines labelled D0 through D7 make up the data bus. It enables external interrupt request.8085 contains of 16-bit programmed counter (PC) and stack pointer (SP) (SP). Six 8-bit general purpose register grouped in pairs: BC, DE, HL. It functions at 3 MHz, 5 MHz, and 6 MHz on the Serial in/Serial out Port and needs a power source of +5V to function properly. It is protected by a DIP enclosure with 40 pins (Dual in line package.
