ATMEL megaAVR Microcontrollers

Atmel® megaAVR® microcontrollers (MCUs) are the ideal choice for designs that need some extra muscle. For applications requiring large amounts of code, megaAVR devices offer substantial program and data memories with performance up to 20 MIPS. Meanwhile, innovative Atmel picoPower® technology minimizes power consumption. All megaAVR devices offer self-programmability for fast, secure, cost-effective in-circuit upgrades. You can even upgrade the Flash memory while running your application.

Based on proven, industry-leading technology, the megaAVR family offers our widest selection of devices in terms of memories, pin-counts and peripherals. These include everything from general-purpose devices to models with specialized peripherals like Peripheral Touch Controller (PTC), USB, LCD controllers, as well as CAN, LIN and Power Stage Controllers (PSC). You will easily find the perfect fit for your project in the megaAVR product family. All these devices are supported by the Atmel Studio development platform, which further reduces your time-to-market.

Key Features

• Broad family — The megaAVR family 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 devices feature ultra-low power consumption and individually selectable low-power sleep modes that make them ideal for battery-powered applications.
• High integration — Devices feature on-chip Flash, SRAM, internal EEPROM, SPI, TWI (I²C), 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 the bill-of-materials.
• Analog functions — Advanced analog capabilities include ADC, DAC, a built-in temperature sensor and internal voltage reference, brown out detector, a fast analog comparator and a programmable analog gain amplifier. This high level of integration allows designs with fewer external analog components.
• Rapid development — megaAVR MCUs speed development with powerful in-system programming and on-chip debug. In addition, in-system programming simplifies production line programming and field upgrades.
• IoT ready — The IoT (Internet of Things) can extend to almost any application—from typical building and home automation to medical and healthcare systems. IoT designs typically require some form of processing power to perform embedded computing tasks and transmit data to the Internet. Increasingly, these devices are battery driven, thus power consumption often becomes the key success factor for a user-friendly IoT-enabled product. megaAVR devices are among the best MCUs in the world when it comes to power consumption, making them a natural choice for IoT applications.
