8089A-AVR-09/07
The 8-bit Timer/Counter2 of ATmega48/88/168 and ATmega48P/88P/168P/328P has
not been implemented in ATtiny48/88.
The Universal Synchronous and Asynchronous serial Receiver and Transmitter
(USART) have not been implemented in ATtiny48/88.
The option to use an external voltage reference has not been implemented in
ATtiny48/88. The external voltage reference pin (AREF in ATmega48/88/168 and
ATmega48P/88P/168P/328P) has been replaced by a general purpose I/O pin. This
means in ATtiny48/88 it is not possible to use an external bypass capacitor to
stabilize the internal voltage reference.
The differences in Fuse Bytes, Signature Bytes and the Calibration Byte are outlined
in the sections below.
ATtiny48/88, ATmega48/88/168 and ATmega48P/88P/168P/328P have identical high
fuse bytes, but there are some differences in the extended and low fuse bytes, as
shown in the tables below.
