Measured under conditions of Ta=25°C and no load.
The supply current during operation, I
DD1
(I
DD2
), is measured under the
following conditions: After all I/O pins are set to input mode and the oscillation
is set to <NORMAL mode>, the MMOD pin is fixed at V
SS
, the input pins are
fixed at V
DD
, and a 20MHz (8.39MHz) square wave of amplitude V
DD
,V
SS
is input
to the OSC1 pin.
The supply current during operation, I
DD3
, is measured under the following
conditions: After all I/O pins are set to input mode and the oscillation is set to
<SLOW mode>, the MMOD pin is fixed at V
SS
, the input pins are fixed at V
DD
,
and a 32.768kHz square wave of amplitude V
DD
,V
SS
is input to the XI pin.
The supply current during HALT mode, I
DD5
(I
DD6
), is measured under the
following conditions: After all I/O pins are set to input mode and the oscillation
is set to <HALT mode>, the MMOD pin is fixed at V
SS
, the input pins are fixed
at V
DD
, and an 32.768kHz square wave of amplitude V
DD
,V
SS
is input to the XI
pin.
The supply current during STOP mode I
DD7
(I
DD8
) is measured under the following
conditions: After the oscillation mode is set to <STOP mode>, the MMOD pin is
fixed at V
SS
, the input pins are fixed at V
DD
, and the OSC1 and XI pins are
unconnected.
