Figure 4.

20-pin SO and DIP package pinout

Legend / Abbreviations for Table 3: Type: I = input, O = output, S = supply

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

Output level: HS = 20mA 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

Note:

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

in reset state.

In the open-drain output column, T defines a true open-drain I/O (P-Buffer and protection diode to VDD are not

implemented).

Available on ST7FOXK2 only.

It is mandatory to connect all available VDD and VDDA pins to the supply voltage and all VSS and VSSA pins to ground.
