10. Voltage Step-down Circuit Stabilization Time
MB89930A series contains the following products and the operating characteristics vary with whether they
contain the internal step-down circuit.
Part number
Operating voltage
The same built-in resources are used for the above product types; operating sequences after the power-on reset
are different depending on whether they have the internal voltage step-down circuit.
The operating sequences after the power-on reset with the different models will be described below.
As described above, CPU starts at delayed time with the product having the internal voltage step-down circuit
compared with the product not having the internal voltage step-down circuit. This is because the time should be
allowed for the stabilization time for voltage step-down circuit for normal operation.
