Leakage Current â General Purpose I/O
over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted)

PARAMETER
High-impedance leakage current
TEST CONDITIONS
(1) (2)
VCC
1.8 V/3 V
MIN MAX UNIT

(1) The leakage current is measured with VSS or VCC applied to the corresponding pin(s), unless otherwise noted.
(2) The leakage of the digital port pins is measured individually. The port pin is selected for input and the pullup/pulldown resistor is
disabled.
Outputs â General Purpose I/O (Full Drive Strength)
over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted)
PARAMETER
VOH High-level output voltage
VOL Low-level output voltage

(1) The maximum total current, I(OHmax) and I(OLmax), for all outputs combined should not exceed ±48 mA to hold the maximum voltage drop
specified.
(2) The maximum total current, I(OHmax) and I(OLmax), for all outputs combined should not exceed ±100 mA to hold the maximum voltage
drop specified.
Outputs â General Purpose I/O (Reduced Drive Strength)
over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted)(1)

specified.
(3) The maximum total current, I(OHmax) and I(OLmax), for all outputs combined, should not exceed ±100 mA to hold the maximum voltage
drop specified.
