Atmega series of AVR microcontrollers

Topics:

As all AVR microcontrollers Atmega microcontrollers are 8 bit RISC microcontrollers. Their core are the same as tiny series, just they are more powerful and has more peripheral devices built in like:

  • Flash memory is in range 8...256kB;

  • RAM is in range 1...4kB;

  • EEPROM is from 512B to 4kB;

  • SPI interface;

  • JTAG programming and debugging interface;

  • Self programming capability (boot-loading);

  • 4 types of clocking;

  • Power down modes;

  • BOD - Brown Out Detecting;

  • Up to 27 sources of interrupts;

  • Hardware multiplier;

  • 8 bit and 16 bit timers;

  • WDT – Watch Dog Timer;

  • Up to 3 channel PWM generation;

  • Analog comparator;

  • 10 bit ADC;

  • UART and USART;

  • I2C or TWI interface.

  • Working frequencies up to 20MHz.
