The Next Step in AVR Microcontroller Capacity and Performance

When your designs need some extra muscle, you need the megaAVR®. Ideal for applications requiring large amounts of code, the megaAVR offers substantial program and data memories with performance up to 20 MIPS. Innovative picoPower® technology minimizes power consumption. All megaAVRs offer self-programmability for fast, secure, cost-effective in-circuit upgrades. You can even upgrade the flash while running your application.

Based on industry-leading, proven technology, the megaAVR family offers our widest selection of devices in terms of memories, pin-counts and peripherals. Choose from general-purpose devices to models with specialized peripherals like USB, or LCD controllers, or CAN, LIN and Power Stage Controllers. It's easy to find the perfect fit for your project in the megaAVR product family. Being supported by the Atmel Studio development platform further reduces your time-to-market.

Key Features

  • Broad family — megaAVR offers our widest selection of devices in terms of memories, pin counts and peripherals, enabling reuse of code and knowledge across projects.
  • picoPower technology — Selected megaAVR features ultra-low power consumption and individually-selectable low-power sleep modes that make it ideal for battery-powered applications.
  • High integration — The megaAVR features on-chip flash, SRAM, internal EEPROM, SPI, TWI, and USART, USB, CAN, and LIN, watchdog timer, a choice of internal or external precision oscillator, and general-purpose I/O pins, simplifying your design and reducing bill-of-materials.
  • Analog functions — Advanced analog capabilities, such as ADC, DAC, built-in temperature sensor and internal voltage reference, brown out detector, a fast analog comparator and a programmable analog gain amplifier. The high level of integration allows designs with fewer external analog components.
  • Rapid development — megaAVR microcontrollers speed development with powerful in-system programming and on-chip debug. In addition, in-system programming simplifies production line programming and field upgrades.
