I/O pin capacitance

1. Max(VDDx) is the maximum value among all the I/O supplies

All I/Os are CMOS-compliant (no software configuration required).

The GPIOs (general purpose input/outputs) can sink or source up to ±8 mA and sink or source up to ±20 mA (with

a relaxed VOL / VOH).

In the user application, the number of I/O pins that can drive current must be limited to respect the absolute

maximum rating specified.

•

The sum of the currents sourced by all the I/Os on VDD, plus the maximum consumption of the MCU

sourced on VDD, cannot exceed the absolute maximum rating ΣIVDD.

•

The sum of the currents sunk by all the I/Os on VSS, plus the maximum consumption of the MCU sunk on

GND, cannot exceed the absolute maximum rating ΣIVGND.
