• All operating
Note: 2. When an oscillator is used for the subclock,
hold V
CC at 2.2 V to 5.5 V from power-on
until the oscillation settling time has elapsed.

• Active (high-speed) mode
• Sleep (high-speed) mode
Note: 1. The fosc values are those when an oscillator
is used; when an external clock is used the
minimum value of fosc is 1 MHz.
