STR73xF Data Brief

13/22

Legend / Abbreviations for Table 3:

Type:

I = input, O = output, S = supply, HiZ= high impedance,

Port and control configuration:

– Input:

pu/pd = with internal 100k

Ω weak pull-up or pull down

– Output:

OD = open drain (logic level)

PP = push-pull

Interrupts:

INTx =external interrupt line

WUPx =Wake-Up interrupt line

The reset state of the I/O ports is input floating. To avoid excess power consumption, unused I/O ports

must be tied to ground.
