ATmega328P-PU

ATmega328, DIP28, new chip, without any bootloader. You will need some ISCP programer (like USBAP) to program this chip. It won't work in Arduino unless You burn it with Arduino bootloader.

If You need ATMega328 with bootloader we have them with Duemilanove bootloader or with UNO bootloader

• 32 kB Flash
• 2 kB RAM
• 1 kB EEPROM
• clock up to 20 MHz (with restrictions on minimum working voltage)
• core AVR8 (8 bit)
