Safety Information    The  following  safety  precautions  must  be  observed  during  all  phases  of  the  operation,  such  as  usage, service or repair of any cellular terminal or mobile incorporating UG95 module. Manufacturers of the cellular terminal should send the following safety information to users and operating personnel and to incorporate these guidelines into all manuals supplied with the product. If not so, Quectel does not take on any liability for customer failure to comply with these precautions.     Full attention must be given to driving at all times in order to reduce the risk of an accident. Using a mobile while driving (even with a handsfree kit) cause distraction and can lead to an accident. You must comply with laws and regulations restricting the use of wireless devices while driving.    Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it switched  off.  The  operation  of  wireless  appliances  in  an  aircraft  is  forbidden  to prevent interference with communication systems. Consult the airline  staff  about the use of wireless devices on boarding the aircraft, if your device offers a Airplane Mode which must be enabled prior to boarding an aircraft.  Switch  off  your  wireless device  when  in hospitals  or clinics  or  other health  care facilities.  These  requests  are  desinged  to  prevent  possible  interference  with sentitive medical equipment.    UMTS  cellular  terminals  or  mobiles  operate  over  radio  frequency  signal  and cellular network and cannot be guaranteed to connect in all conditions, for example no  mobile  fee  or  an  invalid  SIM  card.  While  you  are  in  this  condition  and  need emergent  help,  please  remember  using  emergency  call.  In  order  to  make  or receive call, the cellular terminal or mobile must be switched on and in a service area with adequate cellular signal strength.  Your cellular terminal or mobile contains a transmitter and receiver. When it is ON , it receives and transmits radio frequency energy. RF interference can occur if it is used close to TV set, radio, computer or other electric equipment.  In locations with potencially explosive atmospheres, obey all posted signs to turn off  wireless  devices  such  as  your  phone  or  other  cellular  terminals.  Areas  with potencially exposive atmospheres including fuelling areas, below decks on boats, fuel  or  chemical  transfer  or  storage  facilities,  areas  where  the  air  contains chemicals or particles such as grain, dust or metal powders.

Operating Modes  The table below briefly summarizes the various operating modes referred in the following chapters.  Table 5: Overview of Operating Modes Mode Details   Normal Operation UMTS Idle Software  is  active.  The  module  has  registered  to  the  UMTS network and the module is ready to send and receive data. UMTS Talk/Data UMTS  connection  is  ongoing.  In  this  mode,  the  power consumption is decided by network setting (e.g. TPC pattern) and data transfer rate. HSPA Idle Software  is  active.  The  module  has  registered  to  the  HSPA network and the module is ready to send and receive data. HSPA Data HSPA  data  transfer  is  ongoing.  In  this  mode,  the  power consumption is decided by network setting (e.g. TPC pattern) and data transfer rate. Minimum Functionality Mode AT+CFUN command can set the module entering into a minimum functionality mode without removing the power supply. In this case, both RF function and USIM card will be invalid.   Sleep Mode In this mode, the current consumption of the module will be reduced to the minimal level. During this mode, the module can still receive paging message, SMS and voice call from the network normally. Power Down Mode In  this  mode,  the  power  management  unit  shuts  down  the  power  supply  for  the baseband part and RF part. Only the power supply for RTC remains. Software is not active.  The  serial  interface  is  not  accessible.  Operating  voltage  (connected  to VBAT_RF and VBAT_BB) remains applied.  3.5. Power Saving   3.5.1.

Power Supply 3.6.1.  Power Supply Pins UG95  provides  four  VBAT  pins  dedicated  to  connect  with  the  external  power  supply.  There  are  two separate voltage domains for VBAT.      VBAT_RF with two pads for module RF.   VBAT_BB with two pads for module baseband.  The following table shows the VBAT pins and ground pins.

Decrease Voltage Drop The power supply range of the module is 3.4V~ 4.3V. Because of the voltage drop during the transmitting time, a bypass capacitor of about 100µF with low ESR should be used. Multi-layer ceramic chip (MLCC) capacitor can provide the best combination of low ESR. Three ceramic capacitors (100nF, 33pF, 10pF) are recommended to be applied to the VBAT pins. The capacitors should be placed close to the UG95’s VBAT pins. The following figure shows star structure of the power supply.  The main  power supply from  an external application  has  to  be  a  single  voltage  source  and  has  to  be expanded  to two  sub paths  with star structure.  In  addition, in  order to  get a stable power  source,  it is suggested to use a zener diode of whose reverse zener voltage is 5.1V and dissipation power is more than 0.5W.
                                                                                                                                              UMTS/HSPA  Module  Series                                                                 UG95  Hardware  Design  UG95_Hardware_Design                  Confidential / Released                             25 / 67    ModuleVBAT_RFVBAT_BBVBATC1100uFC6100nFC733pFC810pF++C2100nFC5100uFC333pFC410pFD15.1V Figure 5: Star Structure of the Power Supply  Please pay special attention to the power supply design for applications. Make sure the input voltage will never drop below 3.4V. If the voltage drops below 3.4V, the module will turn off automatically. The PCB traces from the VBAT pins to the power source must be wide enough to ensure that there isn’t too much voltage drop occurs in the transmitting procedure. The width of VBAT_BB trace should be no less than 1mm, and the width of VBAT_RF trace should be no less than 2mm, and the principle of the VBAT trace is the longer, the wider.  3.6.3.  Reference Design for Power Supply The power design for the module is very important, since the performance of power supply for the module largely depends on the power source. The power supply is capable of providing the sufficient current up to 2A at least. If the voltage drop between the input and output is not too high, it is suggested to use a LDO to supply power for module. If there is a big voltage difference between the input source and the desired output (VBAT), a buck converter is preferred to be used as a power supply.  The following figure shows a reference design for +5V input power source. The designed output for the power supply is 3.88V and the maximum load current is 3A.
                                                                                                                                              UMTS/HSPA  Module  Series                                                                 UG95  Hardware  Design  UG95_Hardware_Design                  Confidential / Released                             26 / 67     DC_INC1 C2MIC29302WU U1IN OUTENGNDADJ2 4135VBAT 100nF C3470uFC4100nFR2100K47KR3470uF470R51K R4R11%1%MCU_POWER_ON/OFF 47K4.7KR5R6 Figure 6: Reference Circuit of Power Supply   It is suggested to disconnect power supply to turn off the module when the module is in abnormal state.  3.6.4.

RTC Interface  The RTC (Real Time Clock) can be powered by an external capacitor through the pin VRTC when the module is powered down and there is no power supply for the VBAT. If the voltage supply at VBAT is disconnected, the  RTC can be  powered  by  the  capacitor.  The capacitance determines  the duration of buffering when no voltage is applied to UG95.  The capacitor is charged from  the internal LDO of UG95  when there  is  power  supply for the  VBAT. A serial 1KΩ resistor had been placed on the application inside the module. It limits the input current of the capacitor.  The following figure shows the reference circuit for VRTC backup.  Large Capacitance CapacitorModuleRTC Core1KVRTCC Figure 16: RTC Supply from Capacitor  In order to evaluate the capacitance of capacitor according to the backup time, we have to consider the following parameters:    VRTC - The starting voltage of the capacitor.

Assure the possibility of the length of the trace is less than 200mm.     Keep USIM card signal away from RF and VBAT alignment.   Assure the ground between module and USIM holder short and wide. Keep the width of ground and USIM_VDD no less than 0.5mm to maintain the same electric potential. The decouple capacitor of USIM_VDD should be less than 1uF and must be near to USIM holder.   To  avoid  cross-talk  between  USIM_DATA  and  USIM_CLK,  keep  them  away  with  each  other  and shield them with surrounded ground.     In  order  to  offer  good  ESD  protection,  it  is  recommended  to  add  TVS  such  as  WILL (http://www.willsemi.com) ESDA6V8AV6. The 22Ω resistors should be added in series between the module and the USIM card so as to suppress the EMI spurious transmission and enhance the ESD protection.    3.11.2.

The impedance of USB differential trace is 90ohm.   Pay attention to the influence of junction capacitance of ESD component on USB data lines. Typically, the capacitance value should be less than 2pF such as ESD9L5.0ST5G.   Do not route signal traces under crystals, oscillators, magnetic devices and RF signal  traces. It is important to route the USB differential traces in inner-layer with ground shielding not only upper and lower layer but also right and left side.   Keep the ESD components as closer to the USB connector as possible.  It is suggested to reserve RC circuit near USB connector for debug.  The USB interface is recommended to be reserved for firmware upgrade in your design. The following figure shows the recommended test points.

Storage  UG95 is stored in the vacuum-sealed bag. The restriction of storage condition is shown as below.    Shelf life in sealed bag is 12 months at < 40ºC/90%RH.    After this bag is opened, devices that will be subjected to reflow solder or other high temperature process must be:   Mounted within 72 hours at factory conditions of ≤ 30ºC/60%RH.  Stored at <10% RH.  Devices require bake, before mounting, if:   Humidity indicator card is >10% when read 23ºC±5ºC.  Mounted for more than 72 hours at factory conditions of ≤ 30ºC/60% RH.  If baking is required, devices may be baked for 48 hours at 125ºC±5ºC.   As  plastic  container  cannot  be  subjected  to  high  temperature,  module  needs  to  be  taken  out  from container  to  high  temperature  (125ºC)  bake.  If  shorter  bake  times  are  desired,  please  refer  to IPC/JEDECJ-STD-033 for bake procedure.  7.2. Manufacturing and Welding  The squeegee should push the paste on the surface of  the stencil that makes the paste fill the stencil openings and penetrate to the PCB. The force on the squeegee should be adjusted so as to produce a clean stencil surface on a single pass. To ensure the module soldering quality, the thickness of stencil at the hole of the module pads should be 0.13mm. For details, please refer to document [6].  NOTE

Multi-slot classes are product dependant, and determine the maximum achievable data rates in both the uplink and downlink directions. Written as 3+1 or 2+2, the first number indicates the amount of downlink timeslots, while the second number indicates the amount of uplink timeslots. The active slots determine the total number of slots the GPRS device can use simultaneously for both uplink and downlink communications. The description of different multi-slot classes is shown in the following table.  Table 33: GPRS Multi-slot Classes Multislot Class Downlink Slots Uplink Slots Active Slots 1 1 1 2 2 2 1 3 3 2 2 3 4 3 1 4 5 2 2 4 6 3 2 4 7 3 3 4 8 4 1 5 9 3 2 5 10 4 2 5 11 4 3 5 12 4 4 5
