8051 MICROCONTROLLER: PROGRAMMING AND INTERFACING

Welcome to “8051 Microcontroller: Programming and Interfacing.”
This book serves as a comprehensive guide to understanding and
mastering the intricacies of the 8051 microcontroller, a versatile and
widely used platform in the field of embedded systems.
The journey begins with an introduction to the fundamental
components of a microcontroller system, including the Central
Processing Unit (CPU), memory, I/O unit, and system bus. Readers
are then introduced to the distinctions between microprocessors,
microcomputers, and microcontrollers, laying the groundwork for a
deeper exploration of the 8051 microcontroller.
The book proceeds to delve into the classification of
microcontrollers, exploring parameters such as word length, memory
architecture, core architecture, and instruction set architectures.
Special attention is given to understanding the architecture of the
8051 microcontroller, its programming model, and on-chip memory
organization, including special function registers, internal RAM, and
internal ROM.
