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 pro-
cessing 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 sys-
tem protocol link must be active at all time, only so called "light sleep" is activated inter-
mittently. 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 func-
tions. UEM ASIC contains power supply circuitry, charging, audio processing and RF con-
trol 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 RF. 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 trans-
mit signal paths and also A/D and D/A conversions of received and transmitted audio sig-
nals 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 bus-
ses, 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 ana-
log 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 out-
put signal source selection and gain control is performed by the UEM according to con-
trol 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 mod-
ule is shielded with PWB grounding. Heat generated by the circuitry is conducted out via
the PWB ground planes.
Modes of Operation
The TME-3 has three modes of operation:
