*1: The parameter is based on AVSS

= VSS = 0.0 V.

*2: Apply equal potential to AVCC and VCC. AVR should not exceed AVCC

+ 0.3 V.

*3: VI and VO should not exceed Vcc + 0.3 V. VI must not exceed the rating voltage. However, if the maximum

current to/from an input is limited by some means with external components, the ICLAMP rating supersedes

the VI rating.

*4: Applicable pins: P10 to P15, PF0, PF1 (Inapplicable pins: PG1, PG2)

• Use within recommended operating conditions.

• Use at DC voltage (current).

• +B signal is an input signal that exceeds VCC voltage. The + B signal should always be applied a limiting

resistance placed 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 VCC pin, and this affects

other devices.

• Note that if the + 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.

• Note that analog system input/output pins other than the A/D input pins (LCD drive pins, etc.) cannot accept

+B signal input.

• Sample recommended circuits :

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.
