3.1 Power Supply
The power supply pins of SIM7100C include four VBAT pins (pin 62&63, pin 38&39). VBAT directly
supplies the power to RF and baseband circuit. VBAT directly supplies the power to RF PA and baseband
system. Power Supply Pin
4 VBAT pins are dedicated to connect the supply voltage.

3.1.1 Design Guide
Make sure that the input voltage at the VBAT pin will never drop below 3.15V even during a transmit
when the current consumption up to more than 700mA. If the power voltage drops below 3.15V, the
module may be shut down automatically. Using large tantalum capacitors (above 300uF) will be the best
way to reduce the voltage drops.
For the consideration of RF performance and system stability, some multi-layer ceramic chip (MLCC)
capacitors (0.1/1uF) need to be used for EMC because of their low ESR in high frequencies. Note that
capacitors should be put beside VBAT pins as close as possible. Also User should minimize the PCB trace
impedance from the power supply to the VBAT pins through widening the trace to 80 mil or more on the
board. The following figure is the recommended circuit.
Figure 6: VBAT input application circuit
Note: The Cd, Ce, Cb, Cc and Cf must be mounted for SIM7100C.

In addition, in order to get a stable power source, it is suggested to use a zener diode of which reverse
zener voltage is 5.1V and dissipation power is more than 500mW.

3.1.2 Recommended Power supply circuit
We recommend DCDC or LDO is used for the power supply of the module, make sure that the peak
current of power components can rise up to more than 2A. The following figure is the reference design of
+5V input power supply. The designed output for the power supply is 3.8V, here a linear regulator can be
used.
Figure 7: Reference circuit of the LDO power supply
If there is a big difference between the input voltage and the desired output (VBAT), a switching converter
power will be preferable because of its better efficiency, especially at the high current situation. The
following figure is the reference circuit. Note that DCDC may deprave RF performance because of ripple
current intrinsically.

Figure 8: Reference circuit of the DCDC power supply
3.1.3 Voltage monitor
To monitor the power supply voltage, user can use the AT command “AT+CBC”, this command has two
parameters: the battery status and the voltage value (mV). It will return the capacity percentage and actual
value of battery (at the VBAT pin). The voltage is continuously measured at intervals, whenever the
measured battery voltage is lower than a specific value set by the AT command “AT+CVALARM”. For
example, if the voltage value is set to be 3.4V, the following URC will be presented: “warning! voltage is
low: 3.3v”.
If the voltage is lower than a specific value which is set by the AT command “AT+CPMVT”, the module
will be powered off automatically and AT commands cannot be executed any more.
Note: Under-voltage warning function and under-voltage power-off function are disabled by default.
For more information about these AT command, please refer to Document [1].
3.2 Power on/Power off/Reset Time Sequence
3.2.1 Power on Sequence
SIM7100C can be powered on by PWRKEY pin, which starts normal operating mode.
PWRKEY pin is pulled up with a 200k ohm resistor to 1.8V in module. User can power on the SIM7100C
by pulling the PWRKEY pin down for a short time. The power-on scenarios are illustrated in the following
figures.

on and firmware goes ready, VDD_EXT will be high level.
Note: For details about “AT+CPOF”, please refer to Document [1].
3.2.3 Reset Function
SIM7100C also have a RESET pin (PIN4) to reset the module. This function is used as an emergency reset
only when AT command “AT+CPOF” and the PWRKEY pin has no effect. User can pull the RESET pin

to ground, then the module will reset.
This pin is already pulled up in module, so the external pull-up resistor is not necessary. A 100nF capacitor
close to the RESET pin is strongly recommended. A reference circuit is recommended in the following
figure.

3.3.1 RI Behavior
If UART port is used in Null Modem, the pin “RI” can be used as an interrupt signal to HOST. Normally it
will keep high logic level until certain condition such as receiving SMS, voice call (CSD, video) or URC
reporting, then “RI” will change to low logic level to inform the master (client PC). It will stay low until
the master clears the interrupt event with AT command.

status. Initially it keeps high, when a voice call or CSD call comes, the pin “RI” will change to low for
about 5900ms, then it will return to high level for 100ms. It will repeat this procedure until this call is
answered or hung up.

3.6 PCM Interface
SIM7100C provides hardware PCM interface for external codec. The PCM interface enables
communication with an external codec to support hands-free applications. SIM7100C PCM interface can
be used in two modes: the default mode is auxiliary PCM (8 KHz long sync mode at 128 KHz PCM CLK);
the other mode is primary PCM (8 KHz short sync mode at 2048 KHz PCM CLK). In short-sync
(primary PCM) mode, SIM7100C can be a master or a slave. In long-sync (auxiliary PCM) mode,
SIM7100C is always a master. SIM7100C also supports 3 kinds of coding formats: 8 bits (-law or A-law)

3.6.2 PCM Signal Description
The default PCM interface in SIM7100C is the auxiliary PCM interface. The data changes on the high
level of PCM_CLK and is sampled at the falling edge of PCM_CLK in one period. Primary PCM is
disabled after every power-on or every reset event. So user must use AT command to enable the primary
PCM mode after powering on or resetting the module every time if user wants to use Primary
PCM.SIM7100C PCM Interface can be operated in Master or Slave mode if it is configured to primary
PCM. In Master Mode, the Module drives the clock and sync signals that are sent to the external codec.
When it is in Slave Mode, the external codec drives the clock and sync signals which are sent to the
module. Both PCM modes are discussed in this section followed by additional PCM topics.
3.6.3 Auxiliary PCM (128 KHz PCM clock)
-law coding is supported by the auxiliary PCM. The auxiliary codec port operates with standard
Smart Machine Smart Decision
SIM7100C_User Manual_V1.01 2015-09-19

long-sync timing and a 128 KHz clock. The AUX_PCM_SYNC runs at 8 KHz with 50% duty cycle.
Most -law codec support the 128 KHz clock.

3.8 I2C Interface
I2C is used to communicate with peripheral equipments and can be operated as either a transmitter or
receiver, depending on the device function. Use AT Commands “AT+CRIIC and AT+CWIIC” to read/write
register values of related peripheral equipments connected with I2C interface. Its operation voltage is
1.8V.
3.8.1 I2C Pin Description
Table 26: I2C Pin description
3.8.2 I2C Signal Description
Both SDA and SCL are bidirectional lines, connected to a positive supply via a pull-up resistor
respectively. When the bus is free, both lines are high.
3.8.3 I2C Design Guide
For SIM7100C, the data on the I2C bus can be transferred at rates up to 400kbps. The number of
peripheral devices connected to the bus is solely dependent on the bus capacitance limit of 400pF. Note
that PCB traces length and bending are in users’ control to minimize load capacitance.
Note
：
SDA and SCL have none pulled up resistors in module. So there is need to pull them up in users’
application circuit.

：
1. For SIM7100C, GPIO0, GPIO2, GPIO3 and GPIO5 have multiplex function, user can use
them as PCM interface to connect extend codec. Refer to section 3.11 and document [1] for details.
2. When the module is powered off, make sure all digital interfaces (PCM UART, etc) connected with
peripheral devices have no voltage higher than 0.3V. If users’ design cannot meet above conditions,
high level voltages maybe occur in GPIO pins because current leakage from above digital interfaces
may occur.
3.14 Multi-functional interface

4.2 Antenna Design Guide
SIM7100C provides RF antenna interface. Customer’s antenna should be located in the host board and
connected to module’s antenna pad through micro-strip line or other types of RF trace and the trace
impedance must be controlled in 50Ω. SIMCom recommends that the total insertion loss between the
antenna pad and antenna should meet the following requirements:
●LTE (F<1GHz) <0.5dB
●LTE (1GHz<F<2GHz) <0.9dB
●LTE (2GHz<F) <1.2dB
To facilitate the antenna tuning and certification test, a RF connector and an antenna matching circuit
should be added. The following figure is the recommended circuit.
Figure 32: Antenna matching circuit (MAIN_ANT)
In this figure, the components R4,C3,C4 and R4 is used for antenna matching, the value of components
can only be got after the antenna tuning, usually, they are provided by antenna vendor. By default, the R3,
R4 are 0 Ohm resistors, and the C3, C4 are reserved for tuning.
The RF test connector in the figure is used for the conducted RF performance test, and should be placed as
close as to the module’s antenna pin. The traces impedance between components must be controlled in
50ohm.

In above figure, R1, C1, C2 and R2 are used for diversity antenna matching. By default, the R1, R2 are 0
Ohm resistors, and the C1, C2 are reserved for tuning.
4.3 GNSS (GPS and GLONASS)
SIM7100C merges GNSS (GPS/GLONASS) satellite and network information to provide a
high-availability solution that offers industry-leading accuracy and performance. This solution performs
well, even in very challenging environmental conditions where conventional GNSS receivers fail, and
provides a platform to enable wireless operators to address both location-based services and emergency
mandates.

Note: Performance will vary depending on the environment, antenna type and signal conditions and so
on.
4.3.2 GNSS Operate Mode
SIM7100C supports both A-GPS and S-GPS, and then provides three operating modes: mobile-assisted
mode, mobile-based mode and standalone mode. A-GPS includes mobile-assisted and mobile-based mode.
Smart Machine Smart Decision
SIM7100C_User Manual_V1.01 2015-09-19
58
In mobile-assisted mode, when a request for position location is issued, available network information is
provided to the location server (e.g. Cell-ID) and assistance is requested from the location server. The
location server sends the assistance information to the handset. The handset/mobile unit measures the
GNSS observables and provides the GNSS measurements along with available network data (that is
appropriate for the given air interface technology) to the location server. The location server then
calculates the position location and returns results to the requesting entity.
In mobile-based mode, the assistant data provided by the location server encompasses not only the
information required to assist the handset in measuring the satellite signals, but also the information
required to calculate the handset’s position. Therefore, rather than provide the GNSS measurements and
available network data back to the location server, the mobile calculates the location on the handset and
passes the result to the requesting entity.
In standalone (autonomous) mode, the handset demodulates the data directly from the GNSS satellites.
This mode has some reduced cold-start sensitivity, and a longer time to first fix as compared to the assisted
modes. However, it requires no server interaction and works out of network coverage.
This combination of GNSS measurements and available network information provides:
●High-sensitivity solution that works in all terrains: Indoor, outdoor, urban, and rural
●High availability that is enabled by using both satellite and network information
Therefore, while network solutions typically perform poorly in rural areas and areas of poor cell
geometry/density, and while unassisted, GNSS-only solutions typically perform poorly indoors. The
SIM7100C GNSS solution provides optimal time to fix, accuracy, sensitivity, availability, and reduced
network utilization in both of these environments, depending on the given condition.

on
Sleep
LTE
Module will automatically go into sleep mode if the
conditions of sleep mode are enabling and there is no on air
and no hardware interrupt (such as USB wake-up operation or
data on serial port).
In this case, the current consumption of module will be
reduced to the minimal level.
In sleep mode, the module can still receive paging message
and SMS.
Idle
LTE
Software is active. Module is registered to the LTE network,
and the module is ready to communicate.
Standby
LTE
Module is ready for EDGE/HSPA+ /LTE data transfer, but no
data is currently sent or received. In this case, power
consumption depends on network settings and EDGE/HSPA+
/LTE configuration.
Data
transfer
LTE
There is EDGE/HSPA+/LTE data transfer in progress. In this
case, power consumption is related to network settings (e.g.
power control level); uplink/downlink data rates and GPRS
configuration (e.g. used multi-slot settings).
Minimum
functionality mode
AT command “AT+CFUN” can be used to set the module to a minimum
functionality mode without removing the power supply. In this mode, the RF
part of the module will not work or the USIM card will not be accessible, or
both RF part and USIM card will be closed, and the serial port is still
accessible. The power consumption in this mode is lower than normal mode.
5.2.2 Minimize Power Consumption
There are two modes that SIM7100C achieves low power consumption.
5.2.3 Sleep mode
If peripheral equipments stops working, and there is no on air or hardware interrupts (such as GPIO
interrupts or data on UART), SIM7100C will enter sleep mode automatically. In this mode, SIM7100C can
still receive paging，voice call or SMS from network. If USB interface of SIM7100C is connected to host
CPU, but host CPU does not support USB suspending, then SIM7100C will not enter sleep mode. After
USB is disconnected, SIM7100C will enter sleep mode.
Note: When UART interface is connected with host CPU, SIM7100C cannot enter sleep mode until
RXD is pulled down by the host CPU. If the module is in the idle mode, make sure to pull the RXD to
low level by host CPU. SIMCom recommends using GPIO43 or DTR to wake up the module from host
CPU and to use GPIO41 or RI to wake up the host CPU. Before designing, pay attention to how to
realize waking function and refer to Document[24] and Document[25] for more detail.

5.2.4 Minimum functionality mode
Minimum functionality mode ceases a majority function of module, thus minimizing the power
consumption. This mode is set by the AT command which provides a choice of the functionality levels.
●AT+CFUN=0: Minimum functionality
●AT+CFUN=1: Full functionality (Default)
●AT+CFUN=4: Disable RF function of the module (Flight mode)
If SIM7100C has been set to minimum functionality mode, the module will firstly enter sleep mode, then
the RF function and SIM card function will be closed. In this case, the serial port is still accessible, but RF
function or SIM card will be unavailable. When SIM7100C is in minimum functionality or flight mode, it
can return to full functionality by the AT command “AT+CFUN=1”.
5.3 Current Consumption
The current consumption in suspended mode and without USB connection is listed in the table below.
Here, “suspended mode” means that SIM7100C is connected to USB bus, but it does not transfer data.
Table 46: Current consumption

5.4 EMC and ESD Notes
EMC tests should be performed to detect any potential problems. Possible harmful emissions radiate by
the application to the RF receiver in the receiver band. RF emissions interfere with audio input/output. It is
recommended to shield the sensitive components and trace with common ground and user can add beads
where necessary.
Normally SIM7100C is mounted on customer host board. Although some ESD components have been
added in SIM7100C, to prevent ESD, user should put some ESD components on customers’ board. The
ESD components should be placed beside the connectors which human body might touch, such as SIM
card holder, audio jacks, switches, keys, etc. The following table is the SIM7100C ESD measurement
performance; the results are from SIMCom EVB test.

6.2 Typical Solder Reflow Profile
For customer convenience, SIMCom provides a typical example for a commonly used soldering profile. In
final board assembly, the typical solder reflow profile will be determined by the largest component on the
board, as well as the type of solder/flux used and PCB stack-up. Therefore the soldering profile shown
below is only a generic recommendation and should be adjusted to the specific application and
manufacturing constraints.

Requirements
When in a hospital or other health care facility, observe the restrictions about the use
of mobiles. Switch the cellular terminal or mobile off, medical equipment may be
sensitive to not operate normally for RF energy interference.
Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it is
switched off. The operation of wireless appliances in an aircraft is forbidden to
prevent interference with communication systems. Forget to think much of these

instructions may lead to the flight safety or offend against local legal action, or both.
Do not operate the cellular terminal or mobile in the presence of flammable gases or
fumes. Switch off the cellular terminal when you are near petrol stations, fuel depots,
chemical plants or where blasting operations are in progress. Operation of any
electrical equipment in potentially explosive atmospheres can constitute a safety
hazard.
Your cellular terminal or mobile receives and transmits radio frequency energy while
switched on. RF interference can occur if it is used close to TV sets, radios,
computers or other electric equipment.
Road safety comes first! Do not use a hand-held cellular terminal or mobile when
driving a vehicle, unless it is securely mounted in a holder for hands free operation.
Before making a call with a hand-held terminal or mobile, park the vehicle.
GSM cellular terminals or mobiles operate over radio frequency signals and cellular
networks and cannot be guaranteed to connect in all conditions, for example no
mobile fee or a invalid SIM card. While you are in this condition and need emergent
help, please remember using emergency calls. In order to make or receive calls, the
cellular terminal or mobile must be switched on and in a service area with adequate
cellular signal strength.
Some networks do not allow for emergency call if certain network services or phone
features are in use (e.g. lock functions, fixed dialing etc.). You may have to
deactivate those features before you can make an emergency call.
Also, some networks require that a valid SIM card be properly inserted in the cellular
terminal or mobile.
