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. Apply a voltage between 2.0 V and 5.5 V to the AV
CC
and V
ref
pins by connecting
them to V
CC
, for instance. Set V
ref
≤ AV
CC
.
2. Current dissipation values are for V
IH
min = V
CC
– 0.5 V, V
IL
max = 0.5 V with all output
pins unloaded and the on-chip pull-up resistors in the off state.
3. The values are for V

max = 0.3 V.
4. I
CC
depends on V
CC
and f as follows:
