Figure 5.2 Time delay until Suspend

NOTES:

1. The measurement condition is V

CC = 2.2 to 5.5 V and Topr = -20 to 85°C (N version) / -40 to 85°C (D version).

2. Necessary time until the voltage detection circuit operates when setting to 1 again after setting the VCA25 bit in the VCA2

NOTES:

1. The measurement condition is V

CC = 2.2 to 5.5 V and Topr = -20 to 85°C (N version) / -40 to 85°C (D version).

2. Time until the voltage monitor 1 interrupt request is generated after the voltage passes V
