History

This datasheet deals with product characteristics of AT90PW2 and AT90WM3. It will be updated

as soon as characterization will be done.

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.

Revision

AT90PWM2

AT90PWM3

First revision of parts, only for running production.

AT90PWM2B

AT90PWM3B

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 138.

• Add the PSC software triggering capture - See “PSC 0 Input Capture

• Add bits to read the PSC output activity - See “PSC0 Interrupt Flag

• Add some clock configurations - See “Device Clocking Options Select

AT90PWM2B/3B” on page 30.

• Change Amplifier Synchonization - See “Amplifier” on page 251. and

See “” on page 253.

• Correction of the Errata - See “Errata” on page 348.
