This datasheet deals with product characteristics of AT90PW2 and AT90WM3. It will be updated
as soon as characterization will be done.
Typical values contained in this datasheet are based on simulations and characterization of
other AVR microcontrollers manufactured on the same process technology. Min and Max val-
ues will be available after the device is characterized.

Revision
First revision of parts, only for running production.
Second revision of parts, for all new developments.
The major changes are :
• complement the PSCOUT01, PSCOUT11, PSCOUT21 polarity in
• Add the PSC software triggering capture -
• Add bits to read the PSC output activity -
• Add some clock configurations -
• Change Amplifier Synchonization -
• Correction of the Errata -
