Legend: Shading of rows is to assist in readability of the table.
Note 1: This is the limit to which V
DD can be lowered in Sleep mode, or during a device Reset, without losing RAM data.
2: With BOR enabled, full-speed operation (FOSC = 40 MHz) is supported until a BOR occurs. This is valid although V
DD
may be below the minimum voltage for this frequency.
