Frequently asked questions
How do I program an ATtiny44A?
It is typically programmed through its ISP (in-system programming) interface using an AVR programmer, or via a USB-to-ISP adapter. Some boards and Arduino-based workflows also support it with a board package for ATtiny devices.
Can it run at 3.3 V?
Yes. Its operating voltage range is 1.8 V to 5.5 V, so it can run on a 3.3 V supply, provided the clock speed you use is supported at that voltage.
