5. Electrical Characteristics

NOTES:

1.

°C.

2.

The standard value shows when the HRA1 register is assumed as the value in shipping and the HRA2 register value is set to

00h.

NOTES:

1.

°C.

2.

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

3.

Time until CPU clock supply starts since the interrupt is acknowledged to exit stop mode.

NOTES:

1.

°C / -40 to 85 °C, unless otherwise specified.
