271 / 280 page ![]() Document Number: 002-04662 Rev. *F Page 271 of 280 MB91520 Series Page Section Change Results 46 ■During Power-on The following sentence modified as following: (Error) To prevent a malfunction of the voltage step-down circuit built in the device, the voltage rising must be monotonic increasing during power-on. Power-on prohibits that the voltage goes up and down and voltage rising stops temporarily. (Correct) To prevent a malfunction of the voltage step-down circuit built in the device, the voltage rising must be monotonic during power-on. 142,143 11. Electrical Characteristics Recommended operating conditions The following sentence modified as following: (Error) *1: When it is used outside recommended operation guarantee range (range of the operation guarantee), contact your sales representative. Moreover, minimum value with an effective external low-voltage detection reset becomes a voltage until generating low-voltage detection reset. (Correct) *1: When it is used outside recommended operation guarantee range (range of the operation guarantee), contact your sales representative. 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. 156, 157 11. Electrical Characteristics AC Characteristics Added (3-2) Power-on Conditions for MB91F52xxxE 184 11. Electrical Characteristics AC Characteristics (4-4) I2C timing The following sentence modified as following: (Error) High-speed mode*3 Unit Remarks Min Max Notes: Only ch.3 and ch.4 are standard mode/high-speed mode correspondence. *3: A high-speed mode I2C bus device can be used (Correct) Fast mode*3 Unit Remarks Min Max Notes: Only ch.3 and ch.4 are standard mode/fast mode correspondence. *3: A fast mode I2C bus device can be used |
