The MB90M405 series is a general-purpose 16-bit microcontroller, developed for applications requiring fluorescent
display tube panel control. Each microcontroller is equipped with 60 highly voltage-resistant output pins, needed
Ufor fluorescent display control. The command structure inherits the same AT architecture as the F2MC-8L and
F2MC-16L, in order to provide enhanced C-language support, improved extended/signed multiplication/division
t4instructions in addressing mode, and enhanced bit processing. In addition, an onboard 32-bit accumulator allows
long word processing.
eNote : F2MC stands for FUJITSU Flexible MicroController, and is a registered trademark of Fujitsu Limited.

■ HANDLING DEVICES
This section contains important information on handling the device, regarding the following :
• Do not exceed maximum rated voltage (to prevent latch-up)
• Supply voltage stability
• Power-on precautions
• Treatment of unused pins
• Treatment of A/D converter power supply pin
• Notes on using external clock
• Power supply pin
• Sequence for applying power analog input of A/D converter
• Output of high-voltage output pin (circuit types C & D)
• Do not exceed maximum rated voltage (to prevent latch-up)
• With a CMOS IC, if voltage above VCC or below VSS is applied to an output or input pin other than a medium/
high voltage resistance pin, or if voltage between VCC and VSS, but exceeding the rated voltage, is applied, a
latch-up state could be generated. In the event of a latch-up, the power current will increase drastically, possibly
destroying the chip due to overheating. For this reason, make sure not to exceed the maximum rating.
• When applying or shutting off analog power, make sure that the analog power (AVCC) and analog input voltage
do not exceed the digital power voltage (VCC) .
• Supply voltage stability
Even within the scope of operational protection for VCC power voltage, a sudden increase in power voltage could
cause the unit to malfunction. For this reason, please stabilize the VCC power voltage.
The standard for stabilizing voltage is a VCC ripple fluctuation (peak to peak value) of no more than 10% of
standard VCC power voltage at commercial power frequencies (50 Hz to 60 Hz) , and an excess fluctuation rate
of no more than 0.1 V/ms for instantaneous changes when switching power.
• Power-on precautions
When turning on the power, ensure that the power voltage (VCC) power-up time is at least 50 µs (0.2 V to
2.7 V) , in order to keep the built-in step-down circuit from malfunctioning.
• Treatment of unused pins
Leaving unused input pins free could cause permanent damage due to malfunctions and latch-ups. For this
reason, set unused input pins to pull-up or pull-down via resistance of 2 kΩ or more. Additionally, if there are
unused I/O pins, either set them to output and leave them free, or set them to input and treat them as input pins.
• Notes on using external clock
When using an external clock, please drive pin X1 only, and free pin X1. An example of using an external clock
is shown in the figure below:
