Microchip`s new AVRmega 8-bit MCUs family ATMEGA4809 for Real-time Control with Core Independent Peripherals.

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

Combining intelligent hardware peripherals along with the low-power capability of an AVR® core, megaAVR® microcontrollers (MCUs) broaden the effectiveness of your real-time control systems. Devices like the ATmega4809, ATmega4808, ATmega3209 and ATmega3208 offer individualized options for larger memory, pin counts and packages, while devices such as the ATmega1609, ATmega1608, ATmega809 and ATmega808 offer lower memory and pin-count variants.

In addition to their easy-to-configure Core Independent Peripherals, all of these devices include a high-speed Analog-to-Digital Converter (ADC) that enables efficient noise reduction. This makes devices in the ATmega4809 family optimal as companion MCUs for complex microprocessor-based systems, or as stand-alone 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. These 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 costs.
