1. Product Lineup

The following sentence should be modified as follows:

(Error)

*2: Detection voltage of the external low voltage detection reset (initial) is

2.8V±8% (2.576V to 3.024V). This detection voltage (2.576V) is below the

minimum operation guarantee voltage (2.7V). Between this detection voltage

and the minimum operation guarantee voltage, MCU functions are not

guaranteed except for the low voltage detector. Note that although the detection

level is below the minimum operation guarantee voltage, the LVD reset factor

flag is set as the voltage drops below the detection level.

(Correct)

*2: The initial detection voltage of the external low voltage detection is 2.8V±8%

(2.576V to 3.024V). This LVD setting

and internal LVD cannot be used to reliably generate a reset before voltage dips

below minimum guaranteed operation

voltage, as these detection levels are below the minimum guaranteed MCU

operation voltage. Below the minimum

guaranteed MCU operation voltage, MCU operations are not guaranteed with the

exception of LVD.

*1: When it is used outside recommended operation guarantee range (range of

the operation guarantee), contact your sales representative.
