ISK2

(Quasi-bidirectional, Push-pull Mode, Set GPIO

to output LOW, Apply GPIO pin

VIN=(VSS+0.4)V for VSS and measure the

source current)

4.102

12.351

VDD = VDDIO = 1.8V

ITL

Logic 1 to 0 Transition Current

(Quasi-bidirectional Mode)

-70

VDD = VDDIO = 3.3V

VIN=2.0V

CIO

I/O pin capacitance

4.2

Notes:

1. Guaranteed by characterization result, not tested in production.

2. The ISR and ISK must always respect the abslute maximum current and the sum of I/O, CPU and peripheral must not

exceed ΣIDD and ΣISS.

Test Conditions

VILR

Negative going threshold

(Schmitt input), nRESET

0.3*VDD

VDD = 3.3V

VIHR

Positive going threshold

(Schmitt Input), nRESET

0.7*VDD

VDD = 3.3V

RRST

Internal nRESET pin pull up resistor

VDD = 3.3V,

Notes:

1. Guaranteed by characterization result, not tested in production.

It is recommended to add a 10 kΩ and 10uF capacitor at nRESET pin to keep reset signal stable.
