eUICC
interface
CC2_VPP -- Used for single wire protocol (SWP
NFC) in MFF-XS eUICC.
SWP NFC is currently not
supported and deacti-
vated for the eUICC.
Thus, there are two
options:
If an external SWP mas-
ter is connected never-
theless (or for future use)
the CC2_VPP line should
be pulled up by an exter-
nal 10k resistor to VCC.
If there is no plan to use
SWP the CC2_VPP line
can be grounded.

Maximum cable length or
copper track should be
no longer as 100mm to
eUICC interface.
The signals CC2_RST,
CC2_IO, CC2_CLK and
CC2_VCC are protected
against ESD with a spe-
cial diode array.
If unused keep lines
open.
