Notes:

1. VCC = 1.8 to 5.5 V and Topr =

−20 to 85 °C (N version)/−40 to 85 °C (D version), unless otherwise specified.

2. This enables the setting errors of bit rates such as 9600 bps and 38400 bps to be 0% when the serial interface is used in

UART mode.

Note:

1. VCC = 1.8 to 5.5 V and Topr =

−20 to 85 °C (N version)/−40 to 85 °C (D version), unless otherwise specified.

Notes:

1. The measurement condition is VCC = 1.8 to 5.5 V and Topr = 25

°C.

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