5. Electrical Characteristics
NOTES:
1.
This condition is not applicable when using with Vcc
≥ 1.0V.
2.
When turning power on after the time to hold the external power below effective voltage (Vpor1) exceeds10s, refer to Table
3.
tw(por2) is time to hold the external power below effective voltage (Vpor2).
NOTES:
1.
When not using the voltage monitor 1 reset, use with Vcc
≥ 2.7V.
2.
tw(por1) is time to hold the external power below effective voltage (Vpor1).
