■ HANDLING DEVICES
1.
Preventing latch-up
CMOS IC chips may suffer latch-up under the following conditions :
A voltage higher than VCC pin or lower than VSS pin is applied to an input or output pin.
A voltage higher than the rated voltage is applied between VCC pin and VSS pin.
The AVCC power supply is applied before the VCC voltage.
Latch-up may increase the power supply current drastically, causing thermal damage to the device.
Use meticulous care not to exceed the rating.
For the same reason, also be careful not to let the analog power-supply voltage (AVCC, AVR) exceed the digital
power-supply voltage.
2.
Treatment of unused pins
Leaving unused input pins open may result in permanent damage of the device due to misbehavior or latch-up.
Therefore, they must be pulled up or pulled down through resistors. In this case, those resistors should be more
than 2 k
Ω .
Unused bidirectional pins should be set to the output state and can be left open, or the input state with the above
described connection.
3.
Using external clock
To use external clock, drive the X0 pin and leave X1 pin open.
4.
Precautions for when not using a sub clock signal
If you do not connect pins X0A and X1A to an oscillator, use pull-down handling on the X0A pin and leave the
X1A pin open.
5.
Notes on during operation of PLL clock mode
On this microcontroller, if in case the crystal oscillator breaks off or an external reference clock input stops while
the PLL clock mode is selected, a self-oscillator circuit contained in the PLL may continue its operation at its
self-running frequency. However, Fujitsu Microelectronics will not guarantee results of operations if such failure
occurs.
6.
Power supply pins (VCC/VSS)
If there are multiple VCC and VSS pins, from the point of view of device design, pins to be of the same potential
are connected the inside of the device to prevent malfunction such as latch-up.
To reduce unnecessary radiation, prevent malfunctioning of the strobe signal due to the rise of ground level,
and observe the standard for total output current, be sure to connect the VCC and VSS pins to the power supply
and ground externally.
Connect VCC and VSS pins to the device from the current supply source at a low impedance.
