1. Introduction to 8051 Microcontroller 2. Architecture of 8051

The book 8051 Microcontroller: Internals, Instructions, Programming and Interfacing by Subrata Ghoshal

, published by Pearson Education, is a standard academic resource for learning the architecture and application of the 8051 family. Key Features of the 8051 (as covered by Ghoshal)

The book provides a detailed look at the 8051’s "internals," focusing on its role as a versatile 8-bit microcontroller:

Architecture: Details the Harvard architecture (separate program and data memory) and the 8-bit CPU core.

Memory & Storage: Covers the fixed on-chip RAM and ROM, which make the 8051 ideal for cost-sensitive embedded systems.

I/O Ports: Explains the four bidirectional 8-bit ports (P0, P1, P2, and P3) used for interfacing.

Peripherals: Includes internal timers, UART for serial communication, and interrupt controllers (with 5 standard interrupts).

Programming: Focuses on Assembly language and C programming, teaching students how to write code for arithmetic, logical, and branching operations. Book Contents & Interfacing Topics

Unlike Western textbooks that bury concepts in prose, Ghoshal uses bullet points, flowcharts, and italicized definitions that are perfect for last-minute revision. Every chapter ends with university-style solved problems.

To prove the book’s practical value, here is a classic Ghoshal-style example: Interfacing a 4x4 keypad to display the pressed key on a 7-segment display.

(Assembly snippet – typical of Ghoshal’s teaching style)

ORG 0000H MAIN: MOV P1, #0FH ; Configure lower bits as input CALL SCAN SJMP MAIN

SCAN: MOV P1, #0EFH ; Row 0 low JB P1.0, NEXT1 MOV A, #1 ; Key '1' CALL DISPLAY ...

The book doesn’t just give code. It explains why you need pull-up resistors on Port 1 and how to debounce mechanical switches.
