I/O system current consumption

The current consumption of the I/O system has two components: static and dynamic.

I/O static current consumption

All the I/Os used as inputs with pull-up generate current consumption when the pin is

externally held low. The value of this current consumption can be simply computed by using

the pull-up/pull-down resistors values given in Table 48: I/O static characteristics.

For the output pins, any external pull-down or external load must also be considered to

estimate the current consumption.

Additional I/O current consumption is due to I/Os configured as inputs if an intermediate

voltage level is externally applied. This current consumption is caused by the input Schmitt
