Frequently asked questions
What should I use instead of this chip?
Atmel recommends the ATmega8515 as the replacement for new designs. Compare memory sizes, pinout and peripherals before swapping parts in an existing circuit.
How do I program it?
It is programmed through the ISP interface using an AVR programmer. The Arduino IDE cannot program it directly without an external ISP method and suitable wiring.
