VDD = 3.3 V ± 10% / 5.0 V ± 10%, TA = –40 to 125 °C, unless otherwise specified.

All values need to be confirmed during device validation.

Data based on characterization results, not tested in production.

fCPU 120 MHz + 2% can be achieved over full temperature 125 °C ambient, 150 °C junction temperature.
