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
centered mode - See “PSCn0 & PSCn1 Basic Waveforms in Center
Aligned Mode” on page 139.
• Add the PSC software triggering capture - See “PSC 0 Input Capture
Register – PICR0H and PICR0L” on page 170.
• Add bits to read the PSC output activity - See “PSC0 Interrupt Flag
Register – PIFR0” on page 172.
• Add some clock configurations - See “Device Clocking Options Select
AT90PWM2B/3B” on page 31.
• Change Amplifier Synchonization - See “Amplifier” on page 252. and
See “” on page 254.
• Correction of the Errata - See “Errata” on page 23.
This datasheet deals with product characteristics of AT90PW2 and AT90WM3. It will be updated
as soon as characterization will be done.
2. Disclaimer
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.
