NOTES:
1. V
CC = 2.7 to 5.5 V, Topr = −20 to 85°C (N version) / −40 to 85°C (D version), unless otherwise specified.
2. These standard values show when the FRA1 register value after reset is assumed.
NOTE:
1. V
CC = 2.7 to 5.5 V, Topr = −20 to 85°C (N version) / −40 to 85°C (D version), unless otherwise specified.
NOTES:
1. The measurement condition is V
CC = 2.7 to 5.5 V and Topr = 25°C.
2. Waiting time until the internal power supply generation circuit stabilizes during power-on.
3. Time until system clock supply starts after the interrupt is acknowledged to exit stop mode.
