Pin description

ST7FOXF1, ST7FOXK1, ST7FOXK2

16/226

Legend / Abbreviations for Table 2:

Type: I = input, O = output, S = supply

In/Output level: CT = CMOS 0.3VDD/0.7VDD with input trigger

Output level: HS = 20 mA high sink (on N-buffer only)

Port and control configuration:

●

Input: float = floating, wpu = weak pull-up, int = interrupt, ana = analog

●

Output: OD = open drain, PP = push-pull

The RESET configuration of each pin is shown in bold which is valid as long as the device is

in reset state.
