The Microchip megaAVR family is a well-established microcontroller solution with a wide selection of available devices in production. This way it is possible to identify a perfect fit for the application based on the feature requirements. The megaAVR family ranges from the 4KB Flash ATmega48P with 28 pins up to the 256KB ATmega2560 with 100 pins. If none of the devices in the megaAVR family match the requirements of the application to be developed, one can choose between the tinyAVR family below it or the AVR XMEGA family above it. They all use the same CPU and instruction set!
