GPO characteristics

This section summarizes the operating and measurement conditions of the GPO feature.

The parameters in the DC and AC characteristic tables that follow are derived from tests

performed under the measurement conditions summarized in the relevant tables. GPO is

CMOS compliant.

Note:

The GPO (general purpose output) can sink or source at least 0.7 mA @1.65V , 2mA

@2.7V, 4mA @ 5.5V.

2. Characterization only on bench.

3. When GPO is set in RF Field detection mode return to quiet position could request long time depending of

ST25TA02K-P activity (~20ms).
