2 Interface Characteristics
ALAS5V is equipped with an SMT application interface that connects to the external applica-
tion. The SMT application interface incorporates the various application interfaces as well as
the RF antenna interface.
2.1 Application Interface
2.1.1 Pad Assignment
The SMT application interface on the ALAS5V provides connecting pads to integrate the mod-
ule into external applications. Table 3 lists the pads’ assignments. Figure 3 (bottom view) and
Figure 4 (top view) show the connecting pads’ numbering plan.
Please note that a number of connecting pads are marked as reserved for future use (rfu) and
further qualified as either (<name>), (dnu), (GND) or (nc):
Pads marked as “rfu“ and qualified as “<name>“ (signal name) may be soldered and could
be connected to an external application compliant to the signals’ electrical characteristics
as described in Table 4.
Pads marked "rfu" and qualified as "dnu" (do not use) may be soldered but should not be
connected to an external application.
Pads marked "rfu" and qualified as "GND" (ground) are assigned to ground with ALAS5V
modules, but may have different assignments with future Gemalto M2M products using the
same pad layout.
Pads marked "rfu" and qualified as "nc" (not connected) are internally not connected with
ALAS5V modules, but may be soldered and arbitrarily be connected to external ground.
Also note that some pads are marked with a circle ( ). These pads have a round shape for
improved impedance control.
Gemalto strongly recommends to solder all connecting pads for mechanical stability and heat
dissipation.
Also, Gemalto strongly recommends to provide test points for certain signal lines to and from
the module while developing SMT applications – for debug and/or test purposes during the
manufacturing process. In this way it is possible to detect soldering problems. Please refer to
[3] for more information on test points and how to implement them. The signal lines for which
test points should be provided for are marked as “Test point required” or “Test point recom-
mended“ in Section 2.1.2: Table 4 describing signal characteristics.
