Six I/O pins from UPP port1, which is normally used for keyboard, are used for led con-
trol. Leds are buffered with digital transistors. shows the allocation of led control pins.
Table 7: UI LEDs
The leds are connected between VBAT and ground, and there is a current limiting resistor
and a transistor switch in series with every led. An 1.8V level active high control signal
from UPP KEYB(10:0) switches the leds on and off. The current through a green led is
~15mA, and the current through a red led is ~5mA. This unsymmetry in led drive currents
ensures that the brightnesses of leds are equal.
UPP Processor
UPP contains ARM7 and LEAD3 MCU & DSP cores, RAM memory and custom logic.
The UPP block contains also an external flash memory. TME-3 flash size is 32Mbit.
M2M system
The M2M system block contains the M2M system connector and the glue logic needed to
make connections between application and the TME-3. The application interface of TME-
3 is the standard M2M application interface. The M2M system interface includes FBUS,
MBUS, GENIOUSART, analog and digital audios (multiplexed to same pins), DC input volt-
age, regulated 3.6V battery voltage and some general purpose I/Os.
All signal pins of M2M system are 5V tolerant. The 5V input voltage level is translated
down to 2.78V and 1.8V logic levels for UEM and UPP. The outputs of M2M system are
translated from UPP/UEM 1.8V and 2.78V levels to 3.3V level.
M2M system connector is a 50-pin male connector.
SIM
The SIM block contains a SIM card reader, which is connected to UEM SIM interface.
Audio
TME-3 does not have any built-in audio equipment, such as microphone or earpiece.
All audio signals are routed outside of TME-3 via M2M system connector to an external
audio accessory. The RAE-3 does not include or support vibra and buzzer.
