2. Recommended Operating Conditions
WARNING: The recommended operating conditions are required in order to ensure the normal operation of the
Supply voltage
Analog supply voltage
Analog reference voltage
Operating temperature
Note that if a B signal is input 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 supply voltage may not be sufficient to operate the power-on reset.
Care must be taken not to leave the B input pin open.
Note that analog system input/output pins other than the A/D input pins (LCD drive pins, comparator input
pins, etc.) cannot accept B signal input.

semiconductor device. All of the device’s electrical characteristics are warranted when the device is
operated within these ranges.
Always use semiconductor devices within their recommended operating condition ranges. Operation
outside these ranges may adversely affect reliability and could result in device failure.
No warranty is made with respect to uses, operating conditions, or combinations not represented on
the data sheet. Users considering application outside the listed conditions are advised to contact their
FUJITSU representatives beforehand.
