Notes: 1. If the A/D and D/A converters are not used, do not leave the AV
CC
, V
ref
, and AV
SS
pins open. Connect the AV
CC
and V
ref
pins to V
CC
, and the AV
SS
pin to V
SS
.
2. Current dissipation values are for V
IH min
= V
CC
– 0.2 V and V
IL max
= 0.2 V with all output
pins unloaded and all MOS input pull-ups in the off state.
3. The values are for V

IH
min = V
CC
× 0.9, and V
IL
max = 0.3 V.
4. I
CC
depends on V
CC
and f as follows:
I
CC
max = 1.0 (mA) + 1.10 (mA/(MHz × V)) × V
CC
× f (normal operation)
I
CC
max = 1.0 (mA) + 0.88 (mA/(MHz × V)) × V
CC
× f (sleep mode)
