Notes
1) Sudden change in supply voltage during operation may initiate a power-on sequence. To change supply volt-
age during operation, it is recommended to smoothly raise the voltage to avoid rapid fluctuations in the supply
voltage.
A voltage rising rate of 50 mV/
ms or less is recommended.
2) Set RST pin to “L” level when turning on the device, at least the tRSTL duration after the supply voltage reaches
VCC is necessary before turning the RST to “H” level.
Not less than 3 V
3) If the supply voltage goes below the lower limit of the guaranteed operating voltage range, be sure to restart
the power supply from the VSS level. This is because an internal power-on reset must be generated to restart
operation without allowing the internal circuit to run out of control.
The guaranteed operating voltage range of MB91107 series is from 3.0 to 3.6 V.
