This document provides an overview of advanced embedded systems and microcontrollers. It discusses embedded systems hardware and software design, and introduces three common microcontrollers - the 8051, AVR, and ARM. The 8051 and AVR are 8-bit microcontrollers often used in temperature sensors and other simple applications. The 32-bit ARM microcontroller is more powerful and may be used where safety is critical, like airbags in cars. Microcontrollers combine a CPU, memory, and I/O onto a single chip and are programmed using instructions stored in flash memory.

3. SUBJECT MATTER
• Introduction to Embedded Systems
• 8051 Microcontroller
• AVR Microcontroller
• ARM Microcontroller

4. What is Embedded Systems ? ? ?
•Combination of hardware and Software for a
Dedicated application……
•The software is permanently set into a read-
only memory
•MP3 Player is an Embedded System
•Computer is not an embedded system
•But combination of different embedded
systems

5. MICROCONTROLLER
• Microcontroller is a combination of CPU, RAM,
ROM, TIMERS/COUNTERS, INTRUPTS,
INPUT/OUTPUTS etc. are fabricated on a single
chip.
• They are the heart and soul of many everyday
appliances.
• A group of instructions called Program is fed to its
Flash Memory

6. TYPES OF
MICROCONTROLLER
• 8-Bit
1. 8051 (NXP/PHILIPS P89V51RD2)
2. PIC (PIC16F73, PIC16F877)
3. AVR (ATMEGA16)

7. TYPES OF
MICROCONTROLLER
• 16-Bit
1. PIC (PIC24FXX)
2. TI (MSP430F2013)
• 32-Bit
1. ARM (LPC2148)

8. CHOOSING MICROCONTROLLER
• Now we have 3 options, 8, 16 & 32 bit
microcontroller
• Choice is done on the basis of application
• Example:-
Air bags in cars - 32-bit
Temprature Sensor in AC – 8 bit
