Pin description
ST7LITE49K2
18/245
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.
