Note 1: This is the limit to which VDD can be lowered in Sleep mode, or during a device Reset, without losing RAM
data.
2: With BOR enabled, operation is supported until a BOR occurs. This is valid although V
DD may be below the
minimum rated supply voltage.
3: With BOR enabled, full-speed operation (F
OSC = 64 MHZ) is supported until a BOR occurs. This is valid
although V
DD may be below the minimum voltage for this frequency.

Note 1: The power-down current in Sleep mode does not depend on the oscillator type. Power-down current is
measured with the part in Sleep mode, with all I/O pins in high-impedance state and tied to V
DD or VSS and
all features that add delta current disabled (such as WDT, Timer1 Oscillator, BOR, etc.).
