MB90480/485 Series
80
Note that when the microcontroller drive current is low, such as in the power saving modes, the +B input
potential may pass through the protective diode and increase the potential at the VCC pin, and this may affect
other devices.
Note that if a +B signal is input when the microcontroller current is off (not fixed at 0 V) , the power supply
is provided from the pins, so that incomplete operation may result.
Note that if the +B input is applied during power-on, the power supply is provided from the pins and the
resulting supply voltage may not be sufficient to operate the power-on reset.
Care must be taken not to leave the +B input pin open.
Note that analog system input/output pins other than the A/D input pins (LCD drive pins, comparator input
pins, etc.) cannot accept
+B signal input.
Sample recommended circuits:
*8 : MB90485 series only
P20 to P27, P30 to P37, P40 to P47, P70 to P77 pins can be used as 5 V I/F pin on applied 5 V to VCC5 pin.
P76 and P77 is Nch open drain pin.
*9 : As for P76 and P77 (Nch open drain pin) , even if using at 3 V simplicity (VCC3
= VCC5) , the ratings are applied.
WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current,
temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.
