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 K

Ω ±

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 K

Ω ±

1% pull-up resistor on D+ pin and 15 K

±

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

PU

is measured at V

DD

= 5.0V.
