STR73xF

Block Diagram

13/40

Legend / Abbreviations for Table 3:

Type:

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

In/Output level:

TT= TTL 0.8V / 2V with input trigger

CT= CMOS 0.3VDD/0.7VDD with input trigger

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.
