— 2.85 — V
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 VDD may be below
the minimum rated supply voltage.
3: With BOR enabled, full-speed operation (FOSC = 64 MHz) is supported until a BOR occurs. This is valid
although VDD may be below the minimum voltage for this frequency.
