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
