ATtiny48/88 has less volatile and non-volatile memory than ATmega48/88/168 and
ATmega48P/88P/168P/328P, as shown in the table below. This means some
firmware may have to be re-engineered or recompiled using memory optimisation
algorithms.
Table 5-1. Memory Summary.
ATtiny48/88 has a reduced clock system as compared to ATmega48/88/168 and
ATmega48P/88P/168P/328P.
ATtiny48/88 does not include a crystal oscillator, but all other clocking options of
ATmega48/88/168 and ATmega48P/88P/168P/328P are available, as shown in the
table below.
