Run (Operating) I
DD
measured using external square wave clock source (f
OP
= 8.4 MHz). All inputs 0.2 V from rail.
No dc loads. Less than 100 pF on all outputs. C
L
= 20 pF on OSC2. All ports configured as inputs. OSC2 capaci-
tance linearly affects run I
DD
. Measured with all modules enabled.
Wait I
DD
measured using external square wave clock source (f
OP
= 8.4 MHz). All inputs 0.2 Vdc from rail. No dc
loads. Less than 100 pF on all outputs, C
L
= 20 pF on OSC2. All ports configured as inputs. OSC2 capacitance
linearly affects wait I
DD
. Measured with all modules enabled.
Stop I
DD
measured with OSC1 = V
SS
.
Maximum is highest voltage that POR is guaranteed.
Maximum is highest voltage that POR is possible.
If minimum V
DD
is not reached before the internal POR reset is released, RST must be driven low externally until
minimum V
DD
is reached.
