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
5.9 Reset Circuit Electrical Characteristics (When Not Using Voltage Monitor 1 Reset).
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).
