2. Typical values reflect average measurements at midpoint of voltage range, 25

3. 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 capacitance linearly
affects run I
DD
. Measured with all modules enabled.
4. 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.
5. Stop I
DD
measured with OSC1 = V
SS
. All inputs 0.2 V from rail. No dc loads. Less than 100 pF on all outputs. All ports
configured as inputs.
6. Maximum is highest voltage that POR is guaranteed.
7. Maximum is highest voltage that POR is possible.
8. 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.
