Notes:

VCC = 1.8 to 5.5 V, Topr =

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

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:

VCC = 1.8 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 = 1.8 to 5.5 V and Topr = 25

°C.

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