Voltage
— 1.8 — V DSBOREN = 1 on “LF” device or
“F” device in Deep Sleep
Note 1: This is the limit to which V
DDCORE can be lowered in Sleep mode, or during a device Reset, without losing RAM
data.
2: V
USB should always be maintained  VDD, but may be left floating (high impedance, without external
pull-down) when the USB module is disabled and RC4/RC5 will not be used as general purpose inputs.
3: The device will operate normally until Brown-out Reset occurs, even though V
DD may be below VDDMIN.
