6 Quickly start
6.1 Running
There are two ways to provide power supply to SIM5320AD module: one is to use the 6V power
supply provided in the EVB kit; the other is to use USB port of personal computer.
(1) When user use the power supply, if user insert 6V DC source adapter, user should connect
ADAPTER_VBAT pin and VBAT pin on the EVB board; then insert a valued SIM card and
check if the antenna is connected, and make sure that RF control switch is set to ON; finally
press the on/off switch for about 1 second, and then SIM5320AD module will begin running.
(2) Another option is to use USB port of Computer as power supply. To do so, user need to
connect USB_VBAT pin and VBAT pin on the EVB board, and make sure that RF control
switch is set to ON. Firstly insert the sim card and connect the antenna, then connect the PC
with USB-to-USB cable and press the Power_ON button for one second, then SIM5320AD
will start running.
User can see the light on the EVB flashing at a certain frequency about 1.25Hz. By the state,
user can judge whether the EVB and SIM5320AD is running or not. No function and test can be
executed if user has not connected necessary accessories.
NOTE: This EVB board supports USB power supply when user connects USB_VBAT and
VBAT together.
6.2 Installing Driver
There are 3 ways to connect the module to user’s computer and communicate via HyperTerminal:
(1) Using USB-TO-USB cable;
(2) Using UART-TO-USB cable;
(3) Using UART-TO-UART cable.
In the first case, user need install the module USB driver, which can be got from our FAE or sales;
For the UART to USB driver, user may get it from the CD in the EVB kit; If user use UART to
UART cable, there are certain points to be noticed. One can use UART to UART cable in EVB kit,
if the customers want to use their own UART to UART cable, please make sure that the pin
sequences of it is same as those of cable in EVB kit, pin sequences of which are shown in Figure
9.

6.3 Connecting Net and calling
Once user installs the driver, user can follow steps below to connect to Network.
(1) When user use a UART-UART cable, user need to connect the serial port line to the serial port,
open the HyperTerminal (AT command windows) on user’s Personal computer. The location of
the HyperTerminal in windows2000/XP/Vista can be found from START→accessory→
communication→HyperTerminal. Please set the correct Baud Rate and COM port number, the
Baud Rate of SIM5320AD is 115200, and the COM port number is based on which UART port
user’s serial port line is inserted, user should select the port such as COM1 or COM2 etc.
(2) Connect the antenna to the SIM5320AD module using an antenna transmit line, insert SIM
card into the SIM card holder, and insert handset into its sockets.
(3) Follow the steps of running which has been mentioned above in Sector 5.1, power on the
system, type the AT command from the HyperTerminal, and then the SIM5320AD module will
execute its corresponding function. For example, if user type “AT”, then it should respond “OK”;
if user type “ATI”, it should display product identification information.
(4) If user want to use USB to USB cable, user need to connect the cable to USB port of the
module and the computer, then follow step 1~3.
(5) If user use UART to USB cable, user need to connect the cable to module serial port and the
USB port of the computer, then follow step 1~3.
6.4 Downloading
Connect the USB port line to the USB port, connect the direct current source adapter, run the
download program, and choose the correct image, please follow the QDL downloading menu for

3 Application Interface Specification
3.1
Power Supply
The power supply pins of SIM5320AD include VBAT_RF and VBAT_BB. VBAT_RF directly supplies
the power to RF PA; VBAT_BB supplies the power to the baseband system. For the VBAT_RF, the ripple
due to GSM/GPRS emission burst (every 4.615ms）may cause voltage drop, and the current consumption
rises typically to peak of 2A. So the power supply must be able to provide sufficient current up to 2A. The
following figure is the VBAT_RF voltage ripple wave at the maximum power transmit phase.
The test condition: VBAT_RF=4.0V, VBAT maximum output current =2A, CA=100 µF tantalum capacitor
(ESR=0.7Ω) and CB=1µF(Please refer to Figure 36—Application circuit).

Note: 1.Though the VBAT_RF and VBAT_BB are supplied by the same voltage level, they are different pins. VBAT_RF
is for RF section and VBAT_BB is for baseband system.
2. When the module is power off, users must pay attention to the issue about current leakage. Refer to Chapter 3.10.2
Note2.
3.1.2
Design Guide
Mostly, user connects the VBAT_RF and VBAT_BB pins with one power supply. Make sure that the input
voltage at the VBAT_BB pin will never drop below 3.3V even during a transmit burst when the current
consumption rises up to 2A. If the power voltage drops below 3.3V, the module may be shut down
automatically. Using a large tantalum capacitor (above 100uF) will be the best way to reduce the voltage
drops. If the power current cannot support up to 2A, users must introduce larger capacitor (typical 1000uF)
to storage electric power, especially GPRS multiple time slots emission.
For the consideration of RF performance and system stability, another large capacitor (above 100uF)
should be located at the VBAT_RF pin and some multi-layer ceramic chip (MLCC) capacitors (0.1uF)
need to be used for EMC because of their low ESR in high frequencies. Note that capacitors should be put
beside VBAT_RF 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 8: VBAT input application circuit
There are three sections about how to design and optimize users’ power systems.
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 2A. The following figure is the reference design of +5V input
power supply. The designed output for the power supply is 4.1V, here a linear regulator can be used.

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.

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_BB 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 is disabled by default, user can enable it by the AT command “AT+CVALARM”.
Auto power off feature is disabled by default, user should set it by the AT command “AT+CPMVT” to an appropriate
value. Please refer to Document [1].
3.1.3
RTC Backup
The module uses RTC (Real Time Clock) to update and maintain inherent time and keeps system alive at
no power supply status. The RTC power supply of module can be provided by an external capacitor or a
battery (non-chargeable or rechargeable) through the VRTC. The following figures show various reference
circuits for RTC back up. The discharge current is less than 10uA. If this feature is used, please refer to the
AT commands “AT+CTZU” and “AT +CTZR”.

UART Interface
SIM5320AD provides a UART (universal asynchronous serial transmission) port. It consists of a flexible
7-wire serial interface. The module is as the DCE (Data Communication Equipment) and the client PC is
as the DTE (Data Terminal Equipment). AT commands are entered and serial communication is performed
through UART interface. The application circuit is in the following figures.

3.3.2
Application Guide
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.
Figure 20: RI behaviour in NULL Modem
If Full Modem is used to establish communication between devices, the pin “RI” is another operation
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.

3.5.3
Design Guide
For SIM5320AD, 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：I2C_SDA and I2C _SCL have been pulled up with two 2.2kR resistors to 2.6V level in module. So there is no need
to pull them up in users’ application circuit.
3.6
USB Interface
SIM5320AD module contains a USB interface. This interface is compliant with the USB2.0 specification.
The USB2.0 specification requires hosts such as the computer to support all three USB speeds, namely
low-speed (1.5Mbps), full-speed (12Mbps) and high-speed (480Mbps). USB charging and USB-OTG is
not supported.

Application Guide
Currently SIM5320AD supports the USB suspend and resume mechanism which can help to save power.
If no transaction is on USB bus, SIM5320AD will enter suspend mode. When some events such as voice
call or receiving SMS happen, SIM5320AD will resume normal mode automatically.
Figure 24: USB interface
Because of high bit rate on USB bus, pay attention to influence of junction capacitance of ESD component
on USB data lines. Typically, the capacitance should be less than 4pF @1MHz.
Note：The SIM5320AD has two kinds of interface (UART and USB) to connect to host CPU.
USB interface is mapped
to five virtual ports: “SIMTECH USB Modem”, “SIMTECH NMEA Device”, “SIMTECH ATCOM Device”,
“SIMTECH Diagnostics interface” and “SIMTECH Wireless Ethernet Adapter”.
3.7 SPI Interface
SPI interface of SIM5320AD is master only. It provides a duplex, synchronous, serial communication link

Global Positioning System
SIM5320AD merges GPS 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 GPS receivers fail, and provides a platform to enable
wireless operators to address both location-based services and emergency mandates.

3.9.2
Operate Mode
SIM5320AD 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.
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 GPS
observables and provides the GPS 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 GPS 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 GPS 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 GPS measurements and available network information provides:
SIM5320_Hardware Design_V1.01

2011-11-10
Smart Machine Smart Decision
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, GPS-only solutions typically perform poorly indoors. The
SIM5320AD GPS solution provides optimal time to fix, accuracy, sensitivity, availability, and reduced
network utilization in both of these environments, depending on the given condition.
3.9.3
Application Guide
Users can adopt an active antenna or a passive antenna as GPS signal transceiver. In this document, all
GPS specification mentioned is from passive antenna. The following is the reference circuit.

components can only be obtained after the antenna tuning usually, and they are provided by antenna
vendor.C2 in Figure 27 is used for DC isolation. In active antenna circuit, users must use an external
LDO/DCDC to provide VDD voltage whose value should be taken according active antenna characteristic,
and VDD can be shut down to avoid consuming additional current when not being used.
GPS can be used by NMEA port. User can select NMEA as output through UART or USB. NMEA
sentences are automatic and no command is provided. NMEA sentences include GSV, GGA, RMC, GSA,
and VTG. Before using GPS, user should configure SIM5320AD in proper operating mode by AT
command. Please refer to related document for details. SIM5320AD can also get position location
information through AT directly.
Note:GPS is closed by default, it could be started by AT+CGPS. The AT command has two parameters, the first is on/off,
and the second is GPS mode. Default mode is standalone mode.
AGPS mode needs more support from the mobile telecommunication network. Refer to AGPS application document for
details.
3.10 Multi-functional interface
SIM5320AD merges functions for various applications. It can enrich users’ design and lower the cost of
users’ hardware.
3.10.1 Sink Current Source
The dedicated pin (CURRENT_SINK) is intended for driving passive devices，such as LCD backlight, this
implementation is +5V tolerant and suitable for driving white LEDs. The high-current driver can maintain
a constant current which is set by the AT command “AT+ CLEDITST”, capable of up to 150 mA.

3.10.2 Reset Function
SIM5320AD 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 POWER_ON 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

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.
