GPIO Current differences in datasheet and PSoC Creator

[Michael_K]

Good morning all,

in the datasheet of the PSoC 4100 series the maximum current per GPIO pin is given with 25mA, but in the PSoC Creator is given with 4mA source, 8mA sink. Can the GPIO supply more current than spicified in the PSoC Creator?

The 4/8 mA specification is maintaining a correct logical level at the output. You may draw7sink quite more, but the output level will not be in the low/high range.
