2.1.7 eUICC Interface
As an option TX62/TX82 supports an eUICC in MFF-XS format. This MFF-XS eUICC is located
under the shielding, is only connected to specific module pads, and has no physical connec-
tions with other circuits inside the module. Figure 16 shows an example of how to connect the
eUICC to the module’s SIM interface lines as well as a switch to select whether to use the in-
ternal MFF-XS eUICC or an external plug-in SIM card. Figure 17 shows an example for a direct
connection to the module’s SIM interface lines.

The eUICC interface comprises five lines (plus ground) as listed below in Table 7.
