Notes: 1. If the A/D or D/A converter is not used, the AVCC, V
ref
, and AVSS pins should not be
open. Even if the A/D or D/A converter is not used, connect the AVCC and V
ref
pins to
V
CC
and supply 4.0 V to 5.5 V. In this case, V
ref
≤ AV

.
2. Current consumption values are for V
IH
min = V
CC
– 0.5 V and V
IL
max = 0.5 V, with all
output pins unloaded and the on-chip MOS pull-up transistors in the off state.
3. The values are for V

IH
min = V

× 0.9, and V
IL
max = 0.3 V.
4. I
CC
depends on V
CC
and f as follows:
I
CC
max. = 2.0 (mA) + 0.7 (mA/V) × V
CC
+ 1.4 (mA/MHz) × f + 0.20 (mA/(MHz⋅V)) × V
CC
× f
(normal operation)
I
CC
max. = 1.5 (mA) + 0.6 (mA/V) × V
CC
