Pin multiplexing
The multiple pin configurations by different i.MX 8M Mini/Nano-internal function units must be taken note of.
The pin assignment in Table 3 refers to a TQMa8MxML with i.MX 8M Mini Quad CPU in combination with the Starterkit MBa8Mx.
The pin assignment in Table 5 refers to a TQMa8MxNL with i.MX 8M Nano Quad CPU in combination with the Starterkit MBa8Mx.
A certain i.MX 8M Mini or i.MX 8M Nano derivative listed in Table 7 and Table 8 does not necessarily provide all features
described in Table 3 and Table 5. Details are to be taken from (3) and (4).
NXP provides a pin multiplexing tool, which simplifies the selection and configuration (i.MX Pins Tool – NXP Tool).
The electrical and pin characteristics are to be taken from the i.MX 8M Mini and PMIC documentation, see Table 47.
Attention: Destruction or malfunction, pin multiplexing
Depending on the configuration, many i.MX 8M Mini pins can provide several different functions.
Please take note of the information concerning the configuration of these pins in the i.MX 8M Mini
Reference Manual (1), before integration or start-up of your carrier board / Starterkit.
Improper programming by operating software can cause malfunctions, deterioration or
destruction of the TQMa8MxML.
The descriptions given in the following tables should be taken note of:
−
DNC:
These pins must never be connected and have to be left open.
