CONFIDENTIAL

*6:

· Corresponding pins: all general-purpose ports except P035, 041, 093, 122, P222, P227, P232 and P236.

· Use within recommended operating conditions.

· Use at DC voltage (current).

· The + B signal should always be applied by connecting a limiting resistor between the + B signal and the

microcontroller.

· The value of the limiting resistor should be set so that the current input to the microcontroller pin does not

exceed rated values at any time regardless of instantaneously or constantly when the + B signal is input.

· Note that when the microcontroller drive current is low, such as in the low power consumption modes, the

+ B input potential can increase the potential at the VCC pin via a protective diode, possibly affecting other

devices.

· Note that if the + B signal is input when the microcontroller is off (not fixed at 0 V), since the power is

supplied through the pin, the microcontroller may operate incompletely.

· Note that if the +B signal is input at power-on, since the power is supplied through the pin, the power-on

reset may not function in the power supply voltage.

· Do not leave + B input pins open.

*7: When it is used under this condition, contact your sales representative.

*8: It is a standard when four-layer substrate is used.

*9: Please see to the item of "Product lineup" for details.

*10: It is a condition that can be used by limiting the product type of TEQFP and BGA.

*11: It is a condition that can be used by the package limitation of FPT-144P-M08 and FPT-176P-M07.

*12: It is a condition that can be used by limiting the package of FPT-208P-M06.

Sample recommended circuit

MB91520 series

+B input (12 to 16V)

Protective diode

Limiting resistor current

Semiconductor devices may be permanently damaged by application of stress (including, without limitation,

voltage, current or temperature) in excess of absolute maximum ratings. Do not exceed any of these ratings.
