■ NOTES ON DEVICE HANDLING
Preventing latch-ups
When using the device, ensure that the voltage applied does not exceed the maximum voltage rating.
In a CMOS IC, if a voltage higher than VCC or a voltage lower than VSS is applied to an input/output pin that
is neither a medium-withstand voltage pin nor a high-withstand voltage pin, or if a voltage out of the rating
range of power supply voltage mentioned in "1. Absolute Maximum Ratings" of “
When a latch-up occurs, power supply current increases significantly, which may cause a component to be
thermally destroyed.
Stabilizing supply voltage
Supply voltage must be stabilized.
A malfunction may occur when power supply voltage fluctuates rapidly even though the fluctuation is within
the guaranteed operating range of the VCC power supply voltage.
As a rule of voltage stabilization, suppress voltage fluctuation so that the fluctuation in VCC ripple (p-p value)
at the commercial frequency (50 Hz/60 Hz) does not exceed 10% of the standard VCC value, and the transient
fluctuation rate does not exceed 0.1 V/ms at a momentary fluctuation such as switching the power supply.
Notes on using the external clock
When an external clock is used, oscillation stabilization wait time is required for power-on reset, wake-up
from subclock mode or stop mode.
■ PIN CONNECTION
Treatment of unused input pins
If an unused input pin is left unconnected, a component may be permanently damaged due to malfunctions
or latch-ups. Always pull up or pull down an unused input pin through a resistor of at least 2 k
Ω. Set an
unused input/output pin to the output state and leave it unconnected, or set it to the input state and treat it
the same as an unused input pin. If there is an unused output pin, leave it unconnected.
Power supply pins
To reduce unnecessary electro-magnetic emission, prevent malfunctions of strobe signals due to an increase
in the ground level, and conform to the total output current standard, always connect the VCC pin and the VSS
pin to the power supply and ground outside the device. In addition, connect the current supply source to the
VCC pin and the VSS pin with low impedance.
It is also advisable to connect a ceramic capacitor of approximately 0.1 F as a bypass capacitor between
the VCC pin and the VSS pin at a location close to this device.
DBG pin
Connect the DBG pin directly to an external pull-up resistor.
To prevent the device from unintentionally entering the debug mode due to noise, minimize the distance
between the DBG pin and the VCC or VSS pin when designing the layout of the printed circuit board.
The DBG pin should not stay at “L” level after power-on until the reset output is released.
RST pin
Connect the RST pin directly to an external pull-up resistor.
To prevent the device from unintentionally entering the reset mode due to noise, minimize the distance
between the RST pin and the VCC or VSS pin when designing the layout of the printed circuit board.
The PF2/RST pin functions as the reset input/output pin after power-on. In addition, the reset output function
of the PF2/RST pin can be enabled by the RSTOE bit in the SYSC register, and the reset input function or
the general purpose I/O function can be selected by the RSTEN bit in the SYSC register.
Analog power supply
Always set the same potential to AVCC and VCC pins. When VCC is larger than AVCC, the current may flow
through the AN00 to AN07 pins.
