nRF52810 Hardware version issue

[james]

Hi, I want to know what is the different between QFAAB0 and QFAAD0. The IO of  QFAAD0 version  seems to be broken down easily.Maximum 4mA current flows into IO.

Hi James,

See nRF52810 PS/GPIO/ Electrical specification.

If you have GPIO configured in the standard drive, the spec says it can max sink 4 mA:

Symbol	Description	Min.	Typ.	Max.	Units
IOL,SD	Current at VSS+0.4 V, output set low, standard drive, VDD ≥1.7	1	2	4	mA

If you want to sink more current, you need to configure pin in high drive mode. This should not differ between the two revisions you mention.

thanks. All GPIOS can be configured to high drive mode?
