The document discusses the ATmega32 microcontroller. It begins by defining a microcontroller as a small computer containing a processor, memory, and programmable input/output pins. It then lists some key features of the ATmega32 microcontroller, which include 32 I/O pins, 32KB of flash memory, 1024 bytes of EEPROM, and the ability to handle 3 external interrupts. The document also briefly covers the Von Neumann and Harvard architectures and how the ATmega32 is programmed using languages like Assembly, C, and C++ through the AVR studio software.

3. What is a microcontroller..?
A microcontroller (μC) is a small computer on a single
integrated circuit containing a processor, memory, and
programmable input/output Pins.
ATmega32 is an 8-bit high performance microcontroller manufactured By an American
semiconducting company corporation.
Use..?
Microcontrollers are used in automatically controlled
products & devices such as:-
 Automobile engine control systems
 Automatic medical devices
 Remote controlled toys
 Industrial tools and other embedded systems

4. Key features of atmega32
μcontroller
 32 input/output configurable pins.
4portsx8pins=32pins
 32 Kbytes Programmable flash memory.
With 10,000 read/write cycles
 1024 Bytes EEPROM
With 100,000 read/write cycles
 Can handle 3 external interrupts.

5. Features
 Inbuilt Analog to Digital converter.
Pins can sense & directly convert input analog signal to
digital signal.
 131 powerful Instruction sets.
Most of the instruction executes completely just in one
clock cycle only.
 Low power consumption.
Active mode – 0.6 mA current
Idle mode – 0.2 mA current
Power Down mode - <1μA current.

6. Features
 High speed operation at 6MHz frequency.
Processor Speed Extendable up to 16MHz.
 Programming lock for software security.
 Different programmers available in market like isp,
at tiny etc.
 Based on RISC & Harvard Architecture.

7. Von Neumann Architecture
The Von Neumann model is a computer
Architecture which uses same Memory for
User Data and Program.

8. Harvard Architecture
The Harvard model is a computer
Architecture which uses Separate
Memory for User Data and Program
unlike Von Neumon computer
Architecture.

11. Programming for avr atmega32
This microcontroller is easily programmable
using Assembly language, C , C++ and other
basic languages.
The company Atmel corporation, provides AVR
studio for its programming.
It converts assembly language and other basic
language program to .hex file extension.
