Functional Description of TME-3

Circuit Description

The Data module baseband blocks provide the MCU, DSP, external memory interface and
digital control functions in the UPP ASIC . Power supply circuitry, charging, audio pro­cessing and RF control hard ware are in the UEM ASIC.

The purpose of the RF block is to receive and demodulate the radio frequency signal from
the base station and to transmit a modulated RF signal to the base station.

GSM Data Module RL7

The description of the RL7 data module is divided into Baseband and RF sections.

Baseband Module

TME-3 baseband supports a power saving function called "sleep mode". As the M2M sys­tem protocol link must be active at all time, only so called "light sleep" is activated inter­mittently. In this mode the MCU has been shut down but peripherals are active.

TME-3 powered externally and does not have battery and thus there is no need for
charger functions. The power supply is synchronous step down switching type.

Technical Summary

Main functionality of the baseband is implemented into two ASICs: UPP and UEM.

UPP ASIC provides the MCU, DSP, external memory interface and digital control func­tions. UEM ASIC contains power supply circuitry, charging, audio processing and RF con­trol hardware.

Technical Summary

Baseband is running from power rails 2.8V analog voltage and 1.8V I/O voltage. UPP core
voltage Vcore can be lowered down to 1.0V, 1.3V and 1.5V. UEM includes 6 linear LDO
(low drop-out) regulators for baseband and 7 regulators for R F. It also includes 4 current
sources for biasing purposes and internal usage. UEM also includes SIM interface which
supports 3V SIM cards. TME-3 does not currently support 1.8 V SIMs.

The interface between the baseband and the RF section is handled by a UEM ASIC. The
UEM provides A/D and D/A conversion of the in-phase and quadrature receive and trans­mit signal paths and also A/D and D/A conversions of received and transmitted audio sig­nals to and from the user interface. The UEM supplies the analog TXC and AFC signals to
RF section according to the UPP DSP digital control.

Data transmission between the UEM and the UPP is implemented using two serial bus­ses, DBUS for DSP and CBUS for MCU. There are also separate signals for PDM coded
audio. Digital speech processing is handled by the DSP inside UPP ASIC. UEM is a dual
voltage circuit, the digital parts are running from the baseband supply 1.8V and the ana­log parts are running from the analog supply 2.78V. UEM uses also VBAT directly

The baseband supports external microphone inputs and speaker outputs. Input and out­put signal source selection and gain control is performed by the UEM according to con­trol messages from the UPP. Analog and digital PCM audio are routed to M2M system
connector.

EMC shielding for baseband is implemented using metal lids. On the other side the mod­ule is shielded with PWB grounding. Heat generated by the circuitry is conducted out via
the PWB ground planes.

Modes of Ope ration

The TME-3 has three modes of operation:

• RS-232 Mode (M2M system mode)

• Application mode (AT command mode)

• User Control mode

Internally the RL7 module has the following operating modes:

• NO_SUPPLY

• POWER_OFF

•POWER_ON

• RESET

•SLEEP

• PROTECTION

RS232 mode

Fig. 2 shows TME-3 in RS-232 mode. TME-3 enters RS-232 mode in powerup when it
detects a 68k 1% pull-down resistor at M2M system connector pin 21.

In RS-232 mode TME-3 is connected to DAU-12 RS-232 adapter. The adapter provides a
standard RS-232 interface. Power for TME-3 and the adapter is fed through TME-3 DC
jack.

Application mode

In application mode TME-3 is connected to a user specific application. The mechanical
and electrical interface between application and TME-3 is the M2M system connector.
The application can be powered through M2M system or the application can deliver
power to TME-3.

User Control mode

In the user control mode the Nokia 30 GSM Connectivity Terminal is controlled by a
mobile phone. Text message templates that are sent from the mob ile to the Nokia 30
instruct the terminal, which in turn controls a device or machine attached to it through
the M2M System connector.

An example of a device attached to the Nokia 30 for wireless control would be a refrig­erator. You might want to check the temperature of the refrigerator when out of town.
The temperature of the refrigerator could be altered with the mobile as well.

You could also turn off the lights of the apartment that you had accidentally left on by
sending a text message template.

There are three levels of access control for the User control mode.
Firstly, a message identifier entered when the terminal is used for the first time with the

Nokia 30 Configurator is only known by the person who entered it. This identifier begins
every text message template aimed to control the Nokia 30 and the application attached
to it.

Secondly, it can be specified from which phone number the text message templates are
allowed.

Thirdly, a password can be used that is entered whenever a text message template is sent
to the Nokia 30.

(forced by HW)

In NO_SUPPLY mode the phone has no supply voltage.
When battery voltage appears, TME-3 enters RESET mode. In TME-3, RESET mode leads

always to POWER_ON mode. During low activity TME-3 can switch f rom POWER_ON to
SLEEP mode. PROTECTION mode happens if the thermal shutdown of UEM regulators
triggers. PROTECTION mode leads immediately to POWER_OFF mode. TME-3 can enter
POWER_OFF mode also from POWER_ON or SLEEP modes if the UEM internal watchdog
elapses. POWER_OFF mode is not stationary.

In TME-3 there is a special power-up hardware, which essentially presses automatically
the power key as soon as it detects the POWER_OFF mode.
