Requirements of quality
IEC 60068 Environmental testing
DIN EN 60529 IP codes
Compliance with international rules and regulations
Manufacturers of mobile or fixed devices incorporating TC63 modules are advised to have
their completed product tested and approved for compliance with all applicable national and
international regulations. As a quad-band GSM/GPRS engine designed for use on any GSM
network in the world, TC63 is required to pass all approvals relevant to operation on the
European and North American markets. For the North American market this includes the
Rules and Regulations of the Federal Communications Commission (FCC) and PTCRB, for
the European market the R&TTE Directives and GCF Certification Criteria must be fully
satisfied.
The FCC Equipment Authorization granted to the TC63 Siemens reference application is
valid only for the equipment described in Section 8.1.
SAR requirements specific to portable mobiles
Mobile phones, PDAs or other portable transmitters and receivers incorporating a GSM
module must be in accordance with the guidelines for human exposure to radio frequency
energy. This requires the Specific Absorption Rate (SAR) of portable TC63 based
applications to be evaluated and approved for compliance with national and/or international
regulations.
Since the SAR value varies significantly with the individual product design manufacturers are
advised to submit their product for approval if designed for portable use. For European and
US markets the relevant directives are mentioned below. It is the responsibility of the
manufacturer of the final product to verify whether or not further standards, recommendations
or directives are in force outside these areas.
Products intended for sale on US markets
ES 59005/ANSI C95.1 Considerations for evaluation of human exposure to
Electromagnetic Fields (EMFs) from Mobile Telecommunication
Equipment (MTE) in the frequency range 30MHz - 6GHz
Products intended for sale on European markets
EN 50360 Product standard to demonstrate the compliance of mobile phones
with the basic restrictions related to human exposure to
electromagnetic fields (300MHz - 3GHz)
Note: Usage of TC63 in a fixed, mobile or portable application is not allowed without a
new FCC certification.

1.4 Safety Precautions
The following safety precautions must be observed during all phases of the operation, usage,
service or repair of any cellular terminal or mobile incorporating TC63. Manufacturers of the
cellular terminal are advised to convey the following safety information to users and
operating personnel and to incorporate these guidelines into all manuals supplied with the
product. Failure to comply with these precautions violates safety standards of design,
manufacture and intended use of the product. Siemens AG assumes no liability for
customer’s failure to comply with these precautions.
When in a hospital or other health care facility, observe the restrictions on the
use of mobiles. Switch the cellular terminal or mobile off, if instructed to do so
by the guidelines posted in sensitive areas. Medical equipment may be
sensitive to RF energy.
The operation of cardiac pacemakers, other implanted medical equipment
and hearing aids can be affected by interference from cellular terminals or
mobiles placed close to the device. If in doubt about potential danger, contact
the physician or the manufacturer of the device to verify that the equipment is
properly shielded. Pacemaker patients are advised to keep their hand-held
mobile away from the pacemaker, while it is on.
Switch off the cellular terminal or mobile before boarding an aircraft. Make
sure it cannot be switched on inadvertently. The operation of wireless
appliances in an aircraft is forbidden to prevent interference with
communications systems. Failure to observe these instructions may lead to
the suspension or denial of cellular services to the offender, 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. Remember that interference can occur if it is used
close to TV sets, radios, computers or inadequately shielded equipment.
Follow any special regulations and always switch off the cellular terminal or
mobile wherever forbidden, or when you suspect that it may cause
interference or danger.
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
speakerphone operation. Before making a call with a hand-held terminal or
mobile, park the vehicle.
Speakerphones must be installed by qualified personnel. Faulty installation or
operation can constitute a safety hazard.

IMPORTANT!
SOS
Cellular terminals or mobiles operate using radio signals and cellular
networks. Because of this, connection cannot be guaranteed at all times
under all conditions. Therefore, you should never rely solely upon any
wireless device for essential communications, for example emergency calls.
Remember, 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 calls if certain network services or
phone features are in use (e.g. lock functions, fixed dialing etc.). You may
need to deactivate those features before you can make an emergency call.
Some networks require that a valid SIM card be properly inserted in the
cellular terminal or mobile.

Remote SIM Access TC63 supports Remote SIM Access. RSA enables TC63 to use a
remote SIM card via its serial interface, in addition to the SIM card
locally attached to the dedicated lines of the application interface.
In a vehicle mounted scenario, for example, this allows the driver
to access a mobile phone brought into the car from a carembedded phone. The connection between both phones can be a
Bluetooth wireless link or a serial link, e.g. via the car cradle.
The necessary protocols and procedures are implemented
according to the “SIM Access Profile Interoperability Specification
of the Bluetooth Special Interest Group”.

3.1 Operating Modes
The table below briefly summarizes the various operating modes referred to in the following
chapters.
Table 1: Overview of operating modes
Normal operation
GSM / GPRS SLEEP Various power save modes set with AT+CFUN
command.
Software is active to minimum extent. If the module was
registered to the GSM network in IDLE mode, it is
registered and paging with the BTS in SLEEP mode,
too. Power saving can be chosen at different levels:
The NON-CYCLIC SLEEP mode (AT+CFUN=0)
disables the AT interface. The CYCLIC SLEEP modes
AT+CFUN=7 and 9 alternatively activate and deactivate
the AT interfaces to allow permanent access to all AT
commands.
GSM IDLE Software is active. Once registered to the GSM
network, paging with BTS is carried out. The module is
ready to send and receive.
GSM TALK Connection between two subscribers is in progress.
Power consumption depends on network coverage
individual settings, such as DTX off/on, FR/EFR/HR,
hopping sequences, antenna.
GPRS IDLE Module is ready for GPRS data transfer, but no data is
currently sent or received. Power consumption depends
on network settings and GPRS configuration (e.g.
multislot settings).
GPRS DATA GPRS data transfer in progress. Power consumption
depends on network settings (e.g. power control level),
uplink / downlink data rates, GPRS configuration (e.g.
used multislot settings) and reduction of maximum
output power.
POWER DOWN Normal shutdown after sending the AT^SMSO command.
The Power Supply disconnects the supply voltage from the baseband part of
the circuit. Only a voltage regulator is active for powering the RTC. Software is
not active. Interfaces are not accessible.
Operating voltage (connected to BATT+) remains applied.

s
Airplane mode Airplane mode shuts down the radio part of the module, causes the module to
log off from the GSM/GPRS network and disables all AT commands whose
execution requires a radio connection.
Airplane mode can be controlled by using the AT commands AT^SCFG and
AT+CALA:
• With AT^SCFG=MEopMode/Airplane/OnStart the module can be configured
to enter the Airplane mode each time when switched on or reset.
• The parameter AT^SCFG=MEopMode/Airplane can be used to switch back
and forth between Normal mode and Airplane mode any time during
operation.
• Setting an alarm time with AT+CALA followed by AT^SMSO wakes the
module up into Airplane mode at the scheduled time.
Charge-only mode Limited operation for battery powered applications. Enables charging while
module is detached from GSM network. Limited number of AT commands is
accessible. Charge-only mode applies when the charger is connected if the
module was powered down with AT^SMSO.

3.2 Power Supply
TC63 needs to be connected to a power supply at the B2B connector (5 pins each BATT+
and GND).
The power supply of TC63 has to be a single voltage source at BATT+. It must be able to
provide the peak current during the uplink transmission.
All the key functions for supplying power to the device are handled by the power
management section of the analog controller. This IC provides the following features:
• Stabilizes the supply voltages for the GSM baseband using low drop linear voltage
regulators.
• Switches the module's power voltages for the power up and down procedures.
• Delivers, across the VEXT pin, a regulated voltage for an external application. This
voltage is not available in Power-down mode.
• SIM switch to provide SIM power supply.
3.2.1 Minimizing Power Losses
When designing the power supply for your application please pay specific attention to power
losses. Ensure that the input voltage V
even in a transmit burst where current consumption can rise to typical peaks of 2A. It should
be noted that TC63 switches off when exceeding these limits. Any voltage drops that may
occur in a transmit burst should not exceed 400mV.
The measurement network monitors outburst and inburst values. The drop is the difference
of both values. The maximum drop (Dmax) since the last start of the module will be saved. In
IDLE and SLEEP mode, the module switches off if the minimum battery voltage (V
reached.
Example:
V
min = 3.2V
I
Dmax = 0.35V
V
min = VImin + Dmax
batt
V
min = 3.2V + 0.35V = 3.55V
batt
The best approach to reducing voltage drops is to use a board-to-board connection as
recommended, and a low impedance power source. The resistance of the power supply lines
on the host board and of a battery pack should also be considered.
Note: If the application design requires an adapter cable between both board-to-board
connectors, use a flex cable as short as possible in order to minimize power
losses.

Example: If the length of the flex cable reaches the maximum length of 100mm, this
connection may cause, for example, a resistance of 30m in the BATT+ line and
30m in the GND line. As a result, a 2A transmit burst would add up to a total
voltage drop of 120mV. Plus, if a battery pack is involved, further losses may
occur due to the resistance across the battery lines and the internal resistance of
the battery including its protection circuit.

3.2.3 Monitoring Power Supply by AT Command
To monitor the supply voltage you can also use the AT^SBV command which returns the
value related to the reference points BATT+ and GND.
The module continuously measures the voltage at intervals depending on the operating
mode of the RF interface. The duration of measuring ranges from 0.5s in TALK/DATA mode
to 50s when TC63 is in IDLE mode or Limited Service (deregistered). The displayed voltage
(in mV) is averaged over the last measuring period before the AT^SBV command was
executed.

3.3 Power Up / Power Down Scenarios
In general, be sure not to turn on TC63 while it is beyond the safety limits of voltage and
temperature stated in Chapter 5. TC63 would immediately switch off after having started and
detected these inappropriate conditions. In extreme cases this can cause permanent
damage to the module.
3.3.1 Turn on TC63
TC63 can be started in a variety of ways as described in the following sections:
• Hardware driven start-up by IGT line: starts Normal mode or Airplane mode (see Section
3.3.1.1)
• Software controlled reset by AT+CFUN command: starts Normal or Airplane mode (see
Section 3.3.1.3)
• Hardware driven start-up by VCHARGE line: starts charging algorithm and Charge-only
mode (see Section 3.3.1.2)
• Wake-up from Power-down mode by using RTC interrupt: starts Airplane mode
The option whether to start into Normal mode or Airplane mode depends on the settings
made with the AT^SCFG command or AT+CALA. With AT+CALA, followed by AT^SMSO the
module can be configured to restart into Airplane mode at a scheduled alarm time. Switching
back and forth between Normal mode and Airplane mode is possible any time during
operation by using the AT^SCFG command.
After startup or mode change the following URCs indicate the module’s ready state:
• “SYSSTART” indicates that the module has entered Normal mode.
• “^SYSSTART AIRPLANE MODE” indicates that the module has entered Airplane mode.
• “^SYSSTART CHARGE ONLY MODE” indicates that the module has entered the
Charge-only mode.
Detailed explanations on AT^SCFG, AT+CFUN, AT+CALA and Airplane mode can be found
in [1].
3.3.1.1 Turn on TC63 Using Ignition Line IGT
When the TC63 module is in Power-down mode, it can be started to Normal mode or
Airplane mode by driving the IGT (ignition) line to ground. This must be accomplished with an
open drain/collector driver to avoid current flowing into this pin.
The module will start up when both of the following two conditions are met:
• The supply voltage applied at BATT+ must be in the operating range.
• The IGT line needs to be driven low for at least 400ms.
Considering different strategies of host application design the figures below show two
approaches to meet this requirement: The example in Figure 5 assumes that IGT is activated
after BATT+ has already been applied. The example in Figure 6 assumes that IGT is held
low before BATT+ is switched on. In either case, to power on the module, ensure that low
state of IGT takes at least 400ms from the moment the voltage at BATT+ is available.

If configured to a fix baud rate (AT+IPR0), the module will send the URC “^SYSSTART” or

3.3.1.2 Turn on TC63 Using the VCHARGE Signal
As detailed in Section 3.5.7, the charging adapter can be connected regardless of the
module’s operating mode.
If the charger is connected to the charger input of the external charging circuit and the
module’s VCHARGE pin while TC63 is off, and the battery voltage is above the undervoltage
lockout threshold, processor controlled fast charging starts (see Section 3.5.6). TC63 enters
a restricted mode, referred to as Charge-only mode where only the charging algorithm will be
launched.
During the Charge-only mode TC63 is neither logged on to the GSM network nor are the
serial interfaces fully accessible. To switch to normal operation and log on to the GSM
network, the IGT line needs to be activated as described in Section 3.3.1.

3.3.1.3 Reset TC63 via AT+CFUN Command
To reset and restart the TC63 module use the command AT+CFUN. You can enter
AT+CFUN=,1 or AT+CFUN=x,1, where x may be in the range from 0 to 9. See [1] for details.
If configured to a fix baud rate (AT+IPR0), the module will send the URC “^SYSSTART” or
“^SYSSTART AIRPLANE MODE to notify that it is ready to operate. If autobauding is
enabled (AT+IPR=0) there will be no notification. To register to the network SIM PIN
authentication is necessary after restart.
3.3.1.4 Reset or Turn off TC63 in Case of Emergency
Caution: Use the EMERG_RST pin only when, due to serious problems, the software is not
responding for more than 5 seconds. Pulling the EMERG_RST pin causes the loss of all
information stored in the volatile memory. Therefore, this procedure is intended only for use
in case of emergency, e.g. if TC63 does not respond, if reset or shutdown via AT command
fails.
The EMERG_RST signal is available on the application interface. To control the
EMERG_RST line it is recommended to use an open drain / collector driver.
The EMERG_RST line can be used to switch off or to reset the module. In any case the
EMERG_RST line must be pulled to ground for ≥10ms. Then, after releasing the
EMERG_RST line additional activation of IGT for 400 ms will reset the module. If IGT is not
activated for 400 ms the module switches off. In this case, it can be restarted any time as
described in section 3.3.1.1.
After hardware driven restart, notification via “^SYSSTART” or “^SYSSTART AIRPLANE”
URC is the same as in case of restart by IGT or AT command. To register to the network SIM
PIN authentication is necessary after restart.

3.3.2 Turn off TC63
TC63 can be turned off as follows:
• Normal shutdown: Software controlled by AT^SMSO command
• Automatic shutdown: Takes effect if board or battery temperature is out of range or if
undervoltage or overvoltage conditions occur.
3.3.2.1 Turn off TC63 Using AT Command
The best and safest approach to powering down TC63 is to issue the AT^SMSO command.
This procedure lets TC63 log off from the network and allows the software to enter into a
secure state and safe data before disconnecting the power supply. The mode is referred to
as Power-down mode. In this mode, only the RTC stays active.
Before switching off the device sends the following response:
^SMSO: MS OFF
OK
^SHUTDOWN
After sending AT^SMSO do not enter any other AT commands. There are two ways to verify
when the module turns off:
• Wait for the URC “^SHUTDOWN”. It indicates that data have been stored non-volatile
and the module turns off in less than 1 second.
• Also, you can monitor the PWR_IND pin. High state of PWR_IND definitely indicates that
the module is switched off.
Be sure not to disconnect the supply voltage V
been issued and the PWR_IND signal has gone high. Otherwise you run the risk of losing
data. Signal states during turn-off are shown in Figure 7.
While TC63 is in Power-down mode the application interface is switched off and must not be
fed from any other source. Therefore, your application must be designed to avoid any current
flow into any digital pins of the application interface, especially of the serial interfaces. No
special care is required for the USB interface which is protected from reverse current.
