New megaAVR® MCUs


8-bit MCUs built for Real-time Control with Core Independent Peripherals

The megaAVR® MCUs broaden the effectiveness of real-time control systems with a combination of intelligent hardware peripherals alongside the low-power capacity of the AVR core. Each of the ATmega4809, 4808, 3209, and 3208 offer individualized options for pin-counts, packages, and memory. Each includes a high-speed ADC and easy-to-configure Core Independent Peripherals, making the megaAVR family optimal for use as companion MCUs for complex microprocessor-based systems, or as standalone processors in command-and-control environments.


Engineered for Real-time Control

Modern control applications utilize MCUs to increase their performance, while making them more efficient and reliable.  The new megaAVR® devices take the concept further with a peripheral set designed to decrease system response time and increase reliability, while at the same time reducing overall code footprint, validation time, and system development cost.
