OVERVIEW
In Telit modules there are four pins for SIM card holder connection; these lines are:
•SIMVCC (SIM Power supply)
•SIMRST (SIM Reset)
•SIMIO (SIM Data)
•SIMCLK (SIM Clock)
On the modules supporting Hot Insertion/removal of the SIM there is an additional pin for
sensing SIM presence:
•SIMIN (SIM Presence/Absence)
On the modules not supporting Hot Insertion/removal of the SIM, SIM is queried at Startup.
SIM connection design must take in account these general rules:
1) Data Integrity: standard rules for digital layout and routing must be followed taking in
consideration that SIMCLK has frequency of 3.57 MHz and SIMIO baud rate is greater
or equal than 9600Bps
2) EMI/EMC: this is a key aspect to consider designing an application based on TELIT
modules with internal antenna and/or without a proper shielded box. Some of these
conditions may occur:
•antenna picks-up digital noise coming from SIM card lines
•antenna radiated field may interfere digital lines
•digital lines (in particular clock) may radiate spurious in the surrounding space
To overcome all these potential problems, connection lines must be kept as short as possible
and shielded and SIM-holder position has to be as far as possible from antenna.
Besides RF bypass capacitors (10 pF ... 33 pF) closed to SIM card SIM-holder are another
good care.
When connection is not short, insertion of 10 … 47 Ohm resistor with 10 ... 33 pF capacitor
(RC filter) is a good caution to improve EMI from SIMCLK line.
On SIMRST and SIMIO lines is allowed to insert 10 ... 100 Ohm resistor with 10 ... 33 pF
capacitor (RC filter) to improve the EMI measurements.
Do not insert resistors on SIMVCC, their use is not supported by SIM electrical interface.
3) ESD: take ESD caution if application based on TELIT module has SIM holder with
contacts reachable from human body. Refer to chapter 5

Not Subject to NDA
Note/Tip:
SIM card is detected inserted when SIMIN line is shorted to
ground.
If in the application the SIM holder doesn’t foresee the switch for the
presence/absence of the SIM card, the SIMIN line can be connected to
ground or the SIM can be selected as present with the following AT
command:AT#SIMDET=1.
Note/Tip:
On xL865 and xE866 there is no dedicated SIMIN pin. To use the
feature, SIMIN pin has to be configured with the AT command
AT#SIMINCFG=<GPIO_pin> among the available GPIOs. Be careful because
in some products not all GPIOs can be configured for SIMIN function; you can
find the suitable GPIOs in the Hardware User Guide of the single devices or
in their Global Form Factor application note.
Note/Tip:
On GL865-QUAD V4 and GE310-GNSS there is no dedicated SIMIN
pin. Hot Insertion/removal of the SIM is not supported.
Target Market
Figure 2-1 illustrates in particular how the application should be designed and what values
the components should have:

PCB LAYOUT
In this section general rules are given on how to place and connect the components on the
PCB in order to obtain the better results on the EMI side.
The placement of the 33 pF filtering capacitors is very important in order to maximize their
effectiveness; the capacitors should be placed as closest as possible to the SIM pins and
intercepting the tracks that goes to the module. Figure 3-1 and Figure 3-2 show wrong PCB
designs:
Figure 3-1 PCB Layout 1 Figure 3-2 PCB Layout 2
The following Figure 3-3 shows a better design:

ESD PROTECTION
Note/Tip:
If the SIM is accessible to the customer use TVS dioses or varistors
to protect Telit modules from Electrostatic discharge.
ESD protection for SIM interface
It’s possible to use dedicate ESD protection chips with integrated EMI filter designed for the
SIM like ECLAMP2465T or TPD3F303. If these components are used it’s possible avoid
mounting the 33pF capacitors indicated in Figure 2-1, only the 1uF capacitor must remain,
we suggest to leave the solder pads in order to have the possibility to mount the 33pF
capacitors if necessary.

DUAL SIM SELECTION
The Telit modules can already support more than one SIM card, in the following Figure 5-1 is
showed a schematic example of dual SIM connection:
Figure 5-1 Dual SIM
SIM A is enabled using this AT command sequence:
•AT#GPIO=X,1,1
•AT#GPIO=Z,0,1
•AT#GPIO=Y,0,1
•AT#SIMDET=0 (5 seconds of pause)
•AT#SIMDET=2
SIM B is enabled using this AT command sequence:
•AT#GPIO=X,0,1
•AT#GPIO=Z,1,1
•AT#GPIO=Y,1,1
•AT#SIMDET=0 (5 seconds of pause)
•AT#SIMDET=2
If the user doesn't need SIM hot removal he can ground SIMIN pin on module side, in this case
the AT command sequence change a bit because AT#SIMDET has to be set to 1 and not to 2:

•AT#GPIO=X,0,1

•AT#SIMDET=1

•AT#GPIO=Z,0,1
•AT#GPIO=Y,1,1

•AT#SIMDET=1
Note/Tip:
The P-Channel MOSFETS should have a Ron typical around 0.5Ωand
must never exceed 1Ω.
Note/Tip:
On xL865 and xE866 families there is no dedicated SIMIN pin and
AT#SIMDET=1 is the default value. To use the configuration showed in Figure
5-1 the SIMIN pin has to be configured with: AT#SIMINCFG=<GPIO_pin>
(stored in NVM) and AT#SIMDET=2 (stored in the extended profile AT&P).
Be careful because in some products not all GPIOs can be configured for
SIMIN function; you can find the suitable GPIOs in the Hardware User Guide
of the single devices or in their Global Form Factor application note.
Note/Tip:
On GL865-QUAD V4 and GE310-GNSS in the Dual SIM Selection
circuit shown here, the switch IC must be controlled by an external processor
and module shall be rebooted after SIM switching.
It’s also possible use a dedicated IC switch with a low Ron channel for SIMVCC such as
FSA2567:

SIM-ON-CHIP
In the M2M applications, there are several cases where the SIM Card will never be changed
once installed, also it would be preferable if it shouldn’t be possible to remove it at all;
furthermore the SIM Card is required to work in a more harsh environment with respect to
standard mobile phones SIM Cards. In order to address these kinds of application the SIM On
Chip have been developed; they are basically a special SIM Card chip packaged as a surface
mount assembly device that is then assembled together with the modem at the factory and
will be never removed from the application.
This approach results in a great advantage in terms of long term reliability because the
contacting issues that can arise due to moisture, vibrations and harsh environmental
conditions with standard SIM holders are avoided by design since the SIM On Chip is soldered
on the application PCB.
The Telit modules support the usage of M2M SIM-On-Chip and their usage is exactly the same
as for conventional SIM Cards.
SIM On Chip are interfaced with the same lines as for standard SIM:
•SIMVCC
•SIMIO
•SIMRST
•SIMCLK
and shall be connected and decoupled in the same way as the standard SIM Card holder as
shown in the chapter 3.1. An example of SIM On Chip connection is shown in the following
schematic:
Figure 6-1 SIM On Chip connection
Since the SIM On Chip are not removable, it is possible to tie SIMIN to GND and eventually use
the AT command AT#SIMDET to simulate insertion/removal.

SIM Integration Design Guide
80000NT10001A Rev. 15 Page 15 of 32 2021-01-29
Not Subject to NDA
Furthermore if the SIM On Chip is shielded inside the application box and cannot be subject to
ESD discharges, the ESD protections can be omitted.
If there is the need to have both a SIM On Chip and a backup SIM Holder, then a dual SIM
approach can be followed and the connections shall be the same as for chapter 5.

3GPP POWER SAVING MODE (PSM)
Only for LE866, In order to ensure the 3GPP Rel 12 compliance when using the SIM in PSM
states, it is suggested to use two latches on the SIM_RST and SIM_CLK lines.
The two latches are enabled by the PSM_STATUS line as indicated in figure below:
