Notes: 1. Do not leave the AVCC, AV

ref, and AVSS pins open even if the A/D converter and

D/A converter are not used.

Even if the A/D converter and D/A converter are not used, apply a value in the range

2.0 V to 5.5 V to AVCC and AV

ref pins by connection to the power supply (VCC), or some

other method. Ensure that AV

ref ≤ AVCC.

2. P67 to P60 include supporting module inputs multiplexed on those pins.

IRQ2 includes the ADTRG signal multiplexed on that pin.

4. When IICS = 0. Low-level output when the bus drive function is selected is determined

separately.

5. The upper limit of the applied voltage on Ports 6 and A is V

CC +0.3 V when CIN input is

not selected, and the lower of V

CC +0.3 V and AVCC +0.3 V when CIN input is selected.

When a pin is in output mode, the output voltage is equivalent to the applied voltage.

6. Current dissipation values are for V

IH min = VCC –0.5 V, and VIL max = 0.5 V with all

output pins unloaded and the on-chip pull-up MOSs in the off state.

7. The values are for V

RAM ≤ VCC < 4.0 V, VIH min = VCC × 0.9, and VIL max = 0.3 V.

8. For flash memory program/erase operations, the applicable ranges are V

CC = 4.5 V to

5.5 V and T

a = 0 to +75°C (regular specifications) or Ta = 0 to +85°C (wide-range

specifications).
