I am planning to use the ATMega644 in a new design. But on the datasheet of the ATMega644 ATMEL says that the ATMega644 is not recommended for new designs. I thought of buying the ATMega644 from DigiKey as they have already stock of the 644. How is this possible?? Is it save to use the 644 at this point in time, or must I wait until ATMEL says it is save?
