R8C/14 Group, R8C/15 Group 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 (V

por1) exceeds10s, refer to Table

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

3. t

w(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. t

w(por1) is time to hold the external power below effective voltage (Vpor1).
