AVR515
Signature bytes are unique for each device, as shown in the table below.
Table 12-3. Signature bytes.
In ATtiny48/88 there is only one calibration range but in ATmega48/88/168 and
ATmega48P/88P/168P/328P devices there are two, as shown in the table below.
Table 12-4. Oscillator Calibration Register.
The maximum frequency of ATtiny48/88 devices is lower than that of devices
ATmega48/88/168 and ATmega48P/88P/168P/328P, as shown in the table below.
