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
RAM
 ≤ V
CC
 < 3.0 V, 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 = 0.5 (mA) + 0.55 (mA/(MHz × V)) × V
CC
 × f (normal operation) 
I
CC
 max = 0.4 (mA) + 0.44 (mA/(MHz × V)) × V
CC
 × f (sleep mode) 
  5.  Applies on condition that the RES pin is low level at power on.
