2. Typical values reflect average measurements at 3V, 25 °C only.
3. In LDD mode, the specified I
OL
is achieved when the external pullup voltage is equal to or higher than the voltage:
V
OL
+ voltage dropped across LED.
4. Run (operating) I
DD
measured using external square wave clock source (f
XCLK
= 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. All ports configured as inputs. OSC2 capacitance linearly
affects run I
DD
. Measured with all modules enabled.
5. Wait I
DD
measured using external square wave clock source (f
XCLK
= 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. All ports configured as inputs. OSC2 capacitance linearly affects wait I
DD
.
6. Stop I
DD
measured with OSC1 grounded; no port pins sourcing current.
7. Maximum is highest voltage that POR is guaranteed.
