9. Details on Handling C Terminal of MB89530 Series
The MB89530 series contains the following products. The regulator integrated model and the regulator-less
model have different performance characteristics.
Although these product models have the same internal resources, the operation sequence after a power-on
reset is different between the regulator integrated model and regulator-less model.
The operation sequence after a power-on reset of each model is shown below.
As above, the regulator integrated model starts the CPU behind the regulator-less model. This is because the
regulator requires a settling time for normal operation.
The MB89P538 offers a choice of regulator-integrated and regulator-less models selectable depending on the
C-terminal treatment. Use the right one for your mask board.
10. Note to Noise In the External Reset Pin (RST)
If the reset pulse applied to the external reset pin (RST) does not meet the specifications, it may cause malfunc-
tions. Use caution so that the reset pulse less than the specifications will not be fed to the external reset pin (RST) .
