ATMega16 MICROCONTROLLER

At mega is the one of the IC series of a Micro controller. At mega 16 has 16 KB of flash memory. At mega 16 micro controller is a 40 pin wide DIP(Dual Inline Package) chip of At mega series by ATMEL.In At mega 16 Micro controller
At →stands for the company that manufactures Micro controllers i.e. Atmel Corporation.
mega→ stands for family/series of Micro controller.
16→stands for the flash memory of the micro controller ,Here At mega 16 has 16KB of flash memory.

Now we need to know about At mega 16 Micro controller and It's PIN configuration. Every MC is characterized by its PIN configuration.
Atmega 16 micro controller has 40 Pins in which 32 pins(PA0-PA7,PB0-PB7,PC0-PB7,PD0-PD7) are bidirectional and 8(Reset,vcc,Avcc,ref,Aref,Grnd,Xtal1,Xtal2) pins are fixed.
A PIN is input/output pheripheral of a Micro controller. A PORT is collection of 8 pins. Atmega 16 has four ports namely PORTA,PORTB,PORTC,PORTD.
PIN 1-8     → PORTB
PIN 14-21 → PORT D
PIN 22-29 → PORT C
PIN 33-40 → PORT A

PIN DESCRIPTION:

PA0-PA7,PB0-PB7,PC0-PC7,PD0-PD7  are the set of pins used for bidirectional input and output operations.
RESET         → To reset the input.
VCC,AVCC →  For Digital supply voltages.
XTAL1        →   Input to the inverting oscillator amplifier.
XTAL2        →   Output of the inverting oscillator amplifier
AREF          →   Reference pin for ADC
GND            →  Ground.

APPLICATIONS:

 As these Micro controllers are programmable we can use them in electronic devices where artificial intelligence is required.These micro controllers are used in robotics projects like Line follower and Maze Solver etc.,
