0 V.
*2 : Set AV
CC
and V
CC
to the same voltage. Make sure that AV
CC
does not exceed V
CC
and that the voltage at the
analog inputs does not exceed AV
CC
when the power is switched on.
*3 : V
I
and V
O
should not exceed V
CC
0.3 V. V
I
should not exceed the specified ratings. However, if the maximum
current to/from an input is limited by some means with external components, the I
CLAMP
rating supersedes the
V
I
rating.

Use within recommended operating conditions.
Use at DC voltage (current) .
The
B signal should always be applied a connecting limit resistance between the
B signal and the
microcontroller.
The value of the limiting resistance should be set so that when the
B signal is applied the input current to
the microcontroller pin does not exceed rated values, either instantaneously or for prolonged periods.
Note that when the microcontroller drive current is low, such as in the power saving modes, the
B input
potential may pass through the protective diode and increase the potential at the V
CC
pin, and this may
affect other devices.
Note that if a
B signal is inputted when the microcontroller power supply is off (not fixed at 0 V) , the power
supply is provided from the pins, so that incomplete operation may result.
Note that if the
B input is applied during power-on, the power supply is provided from the pins and the
resulting power supply voltage may not be sufficient to operate the power-on reset.
Care must be taken not to leave the
B input pin open.
Recommended circuit sample :
*7 : If used exceeding T
A
105 °C, please consult with us due to the restricted reliability.
It is ensured to write/erase data to the Flash memory between T
A
40 °C and
105 °C.
WARNING:
Semiconductor devices can be permanently damaged by application of stress (voltage, current,
temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.
