3 Blink an LED
4 Long and Short Button Press
5 Wake-Up On Button Press
This example demonstrates the usage of interrupts and sleep modes. In this use case, the microcontroller exits sleep on button press, turns on an LED, and goes back to sleep. On button release, it exits sleep, turns off the LED, and goes back to sleep. The LED is ON while the button is pressed, but the microcontroller can be in sleep mode.

1.4 AVR® DA Family Overview

The figure below shows the AVR® DA devices, laying out pin count variants and memory sizes:

Vertical migration is possible without code modification, as these devices are fully pin and feature compatible
Horizontal migration to the left reduces the pin count, and therefore, the available features

Devices with different Flash memory sizes typically also have different SRAM.
