NOTES:

VCC = 2.2 to 5.5 V, Topr = -20 to 85

°C (N version) / -40 to 85°C (D version), unless otherwise specified.

These standard values show when the FRA1 register value after reset is assumed.

These standard values show when the correction value in the FRA6 register is written to the FRA1 register.

NOTE:

VCC = 2.2 to 5.5 V, Topr = -20 to 85

°C (N version) / -40 to 85°C (D version), unless otherwise specified.

NOTES:

The measurement condition is VCC = 2.2 to 5.5 V and Topr = 25

°C.

Waiting time until the internal power supply generation circuit stabilizes during power-on.

Time until system clock supply starts after the interrupt is acknowledged to exit stop mode.
