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

*9: Corresponding pins: General-purpose ports other than those of P103, P104, P105 and P106.

*10: Corresponding pins: General-purpose ports of P103, P104, P105 and P106.

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.

Use a ceramic capacitor or a

capacitor that has the similar

frequency characteristics. Use a

capacitor with a capacitance

*1: When it is used outside recommended operation guarantee range (range of the operation guarantee),contact your sales

representative.

The initial detection voltage of the external low voltage detection is 2.8 V ± 8 % (2.576 V to 3.024 V). 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
