Hallo veit,
hier ist mal wieder folgendes Motto angesagt: "RTFM"

Zitat:
The ATmega8515 provides all the features of the AT90S4414/8515. In addition, several
new features are added. The ATmega8515 is backward compatible with
AT90S4414/8515 in most cases. However, some incompatibilities between the two
microcontrollers exist. To solve this problem, an AT90S4414/8515 compatibility mode
can be selected by programming the S8515C Fuse. ATmega8515 is 100% pin compatible
with AT90S4414/8515, and can replace the AT90S4414/8515 on current printed
circuit boards. However, the location of Fuse bits and the electrical characteristics differs
between the two devices.


Wobei ich echt positiv vom Preis des ATmega8515 überrascht bin...

Gruß,
SIGINT
