Notes: 1. If the A/D or D/A converter is not used, the AV
CC
, V
ref
, and AV
SS
pins should not be open.
Even if the A/D or D/A converter is not used, connect the AV
CC
and V
ref
pins to V
CC
and
supply 2.0 V to 3.6 V. In this case, V
ref
≤ AV
CC
.
2. Current consumption values are for V
IH
min = V
CC
– 0.2 V and V
IL
max = 0.2 V, with all
output pins unloaded and the on-chip MOS pull-up transistors in the off state.
3. The values are for V
RAM
≤ V
CC
< 2.2 V, V
IH
min = V
CC
– 0.2, and V
IL
max = 0.2 V.
4. I
CC
depends on V
CC
and f as follows:
I
CC
max = 1.0 (mA) + 0.74 (mA/(MHz × V)) × V
CC
× f (normal operation)
I
CC
max = 1.0 (mA) + 0.58 (mA/(MHz × V)) × V
CC
× f (sleep mode)
