General info
How to use this document
The target audiences for this document are all categories of software and hardware
developers, system integrators and expert end-users of SIEMENS GSM wireless modules.
The content applies in particular to current users and developers whose applications are
utilizing SIEMENS TC35/TC37/TC35T for their communications purposes.
The aim of this document is to provide information and offer support in order to facilitate the
transition towards the new generation of SIEMENS wireless modules, namely, TC35i.
Information provided here is based on official technical manuals and released specifications
for TC35 and TC35i. The naming conventions used in this document follow those of source
documentation.
The authors presume the readers are already familiar with the contents of those manuals.
The document presents migration issues in detail using comparison tables between the
modules and covers topics ranging from hardware specifications to AT-command interface.
Technical specifications and interfaces to GSM telecom services are described and
compared in detail as well as all the relevant features. AT-command interface was given
particular attention since it represents the main tool available to developers through which
applications can be controlled. Available commands for both TC35i and TC35T are listed and
classified according to their implementation within each of the modules. Differences in test,
query and execution syntax as well as in available parameters are noted for each command.
Commands are classified in three main groups: jointly supported commands, commands
new with respect to TC35 and TC35 commands not supported by TC35i.

extent. If the GSM engine was
registered to the GSM network in IDLE
mode, it is registered and paging in
SLEEP mode, too. AT interface is not
responding.
Software is active to a minimum extent. If the
module was registered to a GSM network in
IDLE mode, it remains, in SLEEP mode,
registered and pageable from the BTS.
Power saving can be chosen at different levels.
The NON_CYCLIC SLEEP mode (AT+CFUN=0)
disables the AT interface. The CYCLIC SLEEP
mode AT+CFUN=5, 6, 7 and 8 alternatingly
activate and deactivate the AT interface to
allow permanent access to all AT commands.
Software is active. Once registered to the GSM network, paging with BTS is carried out.
The module is ready to send and receive.
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.
Operating voltage is applied. Only a voltage regulator in the Power Supply ASIC is active
for powering the RTC. Software is not active. The RS-232 interface is not accessible.
Restricted operation launched by RTC alert function while the module is in Power Down
mode. Module will not be registered to GSM network. Limited number of AT commands is
accessible. If application is battery powered: No charging functionality in Alarm mode.
Limited operation for battery powered applications. Enables charging while engine is
detached from GSM network. Limited number of AT commands is accessible. There are
several ways to launch Charge-only mode:
æ From Power Down mode: Connect charger to POWER lines when engine was powered
down by AT^SMSO.
æ From Normal mode: Connect charger to POWER lines, then enter AT^SMSO.
Normal operation (SLEEP, IDLE, TALK, DATA) and charging running in parallel. Charge
mode changes to Charge-only mode when the module is powered down before charging
has been completed.

Interface/connectors comparison TC35i/TC35
TC35 and TC35i are equipped with a 40-pin 0.5mm pitch ZIF connector that connects to the
cellular application platform. The mentioned ZIF connector is completely the same for both
devices. The host interface incorporates several sub-interfaces described in the following
chapters
TC35 and TC35i are totally PIN compatible. Some off the TC35 signal names were
changed with TC35i but the functionality is completely identical.

4.4.2 Power up / down scenarios
TC35 and TC35i are fully identical regarding the power up/down scenario with the following
exception:
To actually turn off the TC35i, the emergency shutdown line has to be driven to ground for ≥
3.2s. The TC35 emergency shutdown line needs to be driven to ground for ≥ 3.5s
For further information please consult the HW manual for TC35 and TC35i.
4.4.3 Automatic shutdown
To ensure proper operation of all assemblies under varying conditions, such as temperature,
input voltage, transmission power etc., TC35 and TC35i features protection elements for
automatic shutdown.
Automatic shutdown takes effect if:
• the TC35/TC35i board is exceeding the critical limits of overtemperature or
undertemperature
• the battery is exceeding the critical limits of overtemperature or undertemperature in a
battery application, undervoltage is detected
• overvoltage is detected.
4.4.3.1
Temperature dependent shutdown
The board temperature is constantly monitored by an internal NTC resistor located on the
PCB. The NTC that detects the battery temperature must be part of the battery pack circuit as
described in the manual. The values detected by NTC resistor are measured directly on the
board and the battery and are therefore, not fully identical with the ambient temperature.

RTC backup
The internal Real Time Clock of is supplied from a dedicated voltage regulator in the power
supply ASIC which is also active when TC35 and TC35i are in POWER DOWN status. Alarm
function is included that allows waking up TC35 and TC35i without logging to the GSM
network.
On the TC35i board a serial resistor is placed next to the VDDLP line in order to limit
the input current of an empty capacitor. This eliminates the need of adding a resistor
as required in applications based on the earlier TC35 module.
On the TC35 board there is no resistor placed on the board and it should be added when
designing the GSM application

4.7.4 Audio Interface
Both TC35 and TC35i comprise two analogue audio interfaces, each with an analogue
microphone input and an analogue loudspeaker output (see block diagram below).
To suit several types of equipment, there are several audio modes available which can be
selected with the AT^SNFS command. The electrical characteristics of the voiceband part
vary with the audio mode. For example, sending and receiving amplification, sidetone paths,
noise suppression etc. depend on the selected mode and can be set with AT commands
(except for mode 1).
All analogue microphone inputs and loudspeaker outputs are balanced. A power supply for
electret microphones is implemented in both interfaces, too. If not needed, they have to be
decoupled with capacitors.
Detailed instructions on using AT commands are presented in the AT Command Manual.
TC35i only: Independently of the audio mode, analogue interfaces 1 or 2 can be
selected and configured by AT commands.
Characteristics of audio modes
The electrical characteristics of the voiceband part depend on the current audio mode, set
with AT^SNFS command. Voice band characteristics are the same for TC35 and TC35i. For
further details please consult the HW manual.

Mechanical Dimensions
TC35 and TC35i provide the same type of connectors and mounting holes on the board. The
position of mounting holes is identical as with TC35, as well as the order of external
connectors. The outline mechanical dimensions are identical with both devices except the
high. TC35i is a single side mounted device that makes it much thinner compared to TC35.

4.10 Mounting and installation
Appropriate installation and mounting to the host housing / enclosure is essential for reliable
operation of the GSM engine.
TC35i & TC35
The TC35 board provides three mounting holes. To properly mount it to the host device you
can use M1.6 or M1.8 screws plus suitable washers. The maximum diameter of the screw
head, including the washer, must not exceed 4 mm.
To prevent mechanical damage, be careful not to force, bend or twist the GSM engine. Make
sure it is positioned flat against the host device.
Avoid placing the TC35 board tightly to the host device. Instead, it is recommended
to set the spacers between the module and the host device. If your design approach does not
allow for spacers make sure the host device provides an opening for the RF part.
Avoid exerting any pressure on the shielding covers. Contact springs or other components
must not be fastened to the covers. In extreme conditions, you run the risk of short-circuit if
the cover was damaged or distorted due to pressure. Furthermore, the covers must not be
used to apply any solder joints.
For snap-in concept please be aware that the TC35i PCB is thinner then the TC35

active for 10 minutes (after last character). The sole
exception for wake up is at+cfun=1.
TC35
<fun> parameter accepts only values 0 and
1.
Additional notes

•
To check that ME has entered the
SLEEP mode, it is recommended to
measure the supply current. Depending
on the configuration of the SYNC pin,
the SLEEP mode may also be indicated
by a status LED (see "AT^SSYNC
Configure SYNC Pin", pg. 177).
•
When in SLEEP mode, the following
events may cause the ME to wake up:
incoming call, Real Time Clock alarm,
falling edge of RTS (RS-232, 2.65V
CMOS level) and receipt of an
unsolicited result code (URC, see
chapter 7.1.3).
Additional notes

•
To check the current operation mode see „AT^SSYNC
Configure SYNC Pin", pg. 181.
•
To check if ME has entered SLEEP mode it is necessary
to measure the supply current. SLEEP mode actually
starts after remaining network activities were
terminated.
•
For SLEEP mode functionalities (<fun>=0, 5, 6) will
not work without PIN1.
•
After reset it is necessary to enter PIN1 again.
•
In SLEEP mode the device wakes up by incoming call,
short message, Real Time Clock alarm, falling edge of
RTS (RS-232 levels) and upon receipt of an unsolicited
result code (URC, see chapter 10.1.4).
•
In CYCLIC SLEEP mode device wakes up by incoming
call, short message (only if notification output is
configured using AT+CNMI=1,1), Real Time Clock
alarm and upon receipt of an unsolicited result code
(URC, see chapter 10.1.4). RTS signal is only for
handshake and does not wake up the ME.
•
In CYCLIC SLEEP mode 7 and 8 device wakes up by
incoming call, short message, Real Time Clock alarm
and upon receipt of an unsolicited result code but
continues the CYCLIC SLEEP after the event is
finished. Only with at+cfun=1 the system wakes up
permanently. RTS signal is only for handshake and
does not wake up the ME.

Note:

Note:
The Mobile Equipment storage "ME" has space for
25 short messages.
The storage "MT" is the sum of the storages "ME"
and "SM". The indices (<index>) from 1 to 25 are
associated to the "ME" storage. Indices equal to
26 and higher belong to the "SM" storage.
Incoming short messages with message class 1 or
2 (refer <dcs> GSM 03.38) will be stored in the
"ME" or "SM" storage only. Therefore the ^SMGO:
2 indication (see AT^SMGO) could occur, without
the indication ^SMGO: 1 before.
When switching parameter <mem3> from ''MT'' to
''SM'' the ''ME'' storage will be filled with dummy
short messages. Therefore the execution can last
up to 35 seconds if all the 25 records have to be
written.
When switching back from ''SM'' to ''MT'' the
dummy short messages will be deleted. The
execution could last 35 seconds, too.
In case of short messages present in the ''ME''
storage they will be remembered when switching
back from ''SM'' to ''MT''.
The <mem1>, <mem2> and <mem3> parameter
will be stored in non-volatile memory.
Multiplexer: The parameter <mem3> will be the
same for all instances. The
parameter
<mem2> and <mem3> can differ from one
instance to the other.
