2. Typical values reflect average measurements at midpoint of voltage range, 25 °C only.
3. Run (operating) I
DD
measured using external square wave clock source. 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
CGMXCLK
= 6 MHz); all inputs 0.2 V from rail; no dc loads; less than 100
pF on all outputs. C
L
= 20 pF on OSC2; USB in suspend mode, 15 KΩ ± 5% termination resistors on D+ and D– pins; all ports config-
ured as inputs; OSC2 capacitance linearly affects wait I
DD
.
5. STOP I
DD
measured with USB in suspend mode, OSC1 grounded, 1.425 KΩ ± 1% pull-up resistor on D+ pin and 15 KΩ ± 1% pull-
down resistors on D+ and D– pins, no port pins sourcing current.
6. Maximum is highest voltage that POR is guaranteed.
7. 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.
8. R

is measured at V
DD
= 5.0V.
