Notes:
1. V
CC = 1.8 to 5.5 V, 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. V
CC = 1.8 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 = 1.8 to 5.5 V and Topr = 25°C.
2. Waiting time until the internal power supply generation circuit stabilizes during power-on.
