Frequently asked questions
How do I program the ATMEGA16?
Use an AVR ISP programmer such as a USBasp, which connects over the SPI pins. The chip also supports JTAG for on-chip debugging.
Can I run it from a 3.3 V supply?
The listed operating range is 4.5 to 5.5 V, so a 5 V supply is the standard choice. Check the datasheet before running it at a lower voltage, since the maximum clock speed depends on supply voltage.
