Turning OFF the UC864-E/G/WD/WDU Turning off the device can be done in three ways: • by software command (see UC864-E/G/WD/WDU Software User Guide) • by hardware shutdown • by Hardware Unconditional Restart When the device is shut down by software command or by hardware shutdown, it issues to the network a detach request that informs the network that the device will not be reachable any more. 4.3.1.

UC864-E/G/WD/WDU Hardware User Guide 1vv0300766a Rev.4 - 03/02/09 NOTE: Do not use any pull up resistor on the RESET# line or any totem pole digital output. Using pull up resistor may bring to latch up problems on the UC864-E/G/WD/WDU power regulator and improper functioning of the module. The line RESET# must be connected only in open collector configuration. TIP: The unconditional hardware Restart must always be implemented on the boards and the software must use it as an emergency exit procedure.

A switching power supply will not be suited because of the low drop-out requirements. • When using a linear regulator, a proper heat sink must be provided in order to dissipate the power generated.

PAGE 27
UC864-E/G/WD/WDU Hardware User Guide 1vv0300766a Rev.4 - 03/02/09 • Make sure the low ESR capacitor on the power supply output (usually a tantalum one) is rated at least 10V. • For Car applications a spike protection diode must be inserted close to the power input, in order to clean the supply from spikes. • A protection diode must be inserted close to the power input, in order to save UC864-E/G/WD/WDU from power polarity inversion. This can be the same diode as for spike protection.

Battery Source Power Supply Design Guidelines • The desired nominal output for the power supply is 3.8V and the maximum allowed voltage is 4.2V, hence a single 3.7V Li-Ion cell battery type is suited for supplying the power to the Telit UC864-E/G/WD/WDU module.

UC864-E/G/WD/WDU Hardware User Guide 1vv0300766a Rev.4 - 03/02/09 During trickle charging the voltage across the battery terminals rises; when it reaches the fast charge threshold level the charging process goes into a fast charge phase. During the fast charge phase the process proceeds with a current limited for charging; this current limit depends on the required time for completing the charge and on battery pack capacity.
PAGE 30
UC864-E/G/WD/WDU Hardware User Guide 1vv0300766a Rev.4 - 03/02/09 The UC864-E/G/WD/WDU measures the temperature of its internal component in order to satisfy this last requirement. This not exactly the same as the battery temperature but in common use, the two temperatures must not differ too much and the charging temperature range must be guaranteed.
PAGE 31
UC864-E/G/WD/WDU Hardware User Guide 1vv0300766a Rev.4 - 03/02/09 NOTE: The average consumption during transmissions depends on the power level at which the device is requested to transmit via the network. The average current consumption hence varies significantly. NOTE: The thermal design for the Power supply must be made keeping an average consumption at the max transmitting level during calls of 790mA rms plus 90mA rms for GPS in tracking mode in UC864-G.

UC864-E/G/WD/WDU Hardware User Guide 1vv0300766a Rev.4 - 03/02/09 5.2.3. Power Supply PCB Layout Guidelines As seen in the electrical design guidelines, the power supply must have a low ESR capacitor on the output to cut the current peaks and a protection diode on the input to protect the supply from spikes and polarity inversion. The placement of these components is crucial for the correct working of the circuitry. A misplaced component can be useless or can even decrease the power supply performances.

Whenever this signal is pulled low, UC864-E/G/WD/WDU is reset. When the device is reset it stops all operations.

RS232 Level Translation In order to interface the Telit UC864-E/G/WD/WDU with a PC com port or a RS232 (EIA/TIA-232) application a level translator is required. This level translator must: • invert the electrical signal in both directions; • change the level from 0/2.6V to +15/-15V .
PAGE 42
UC864-E/G/WD/WDU Hardware User Guide 1vv0300766a Rev.4 - 03/02/09 An example of level translation circuitry of this kind is: The example is done with a SIPEX SP3282EB RS232 Transceiver that could accept supply voltages lower than 3V DC. NOTE: In this case Vin has to be set with a value compatible with the logic levels of the module. (Max 2.9V DC). In this configuration the SP3282EB will adhere to EIA/TIA562 voltage levels instead of RS232 (-5 ~ +5V) Reproduction forbidden without Telit Communications S.p.

UC864-E/G/WD/WDU Hardware User Guide 1vv0300766a Rev.4 - 03/02/09 Second solution could be done using a MAXIM transceiver (MAX218) In this case the compliance with RS232 (+-5V) is possible. Another level adapting method could be done using a standard RS232 Transceiver (MAX3237EAI) adding some resistors to adapt the levels on the UC864 Input lines. NOTE: In this case has to be taken in account the length of the lines on the application to avoid problems in case of High-speed rates on RS232.

UC864-E/G/WD/WDU Hardware User Guide 1vv0300766a Rev.4 - 03/02/09 8.3. 5V UART Level Translation If the OEM application uses a microcontroller with a serial port (UART) that works at a voltage different from 2.6 – 2.9V, then a circuitry has to adapt the different levels of the two signal sets. As for the RS232 translation, there are a multitude of single chip translators. For example a possible translator circuit for a 5V TRANSMITTER/RECEIVER can be: Reproduction forbidden without Telit Communications S.

UC864-E/G/WD/WDU Hardware User Guide 1vv0300766a Rev.4 - 03/02/09 TIP: This logic IC for the level translator and 2.6V pull-ups (not the 5V one) can be powered directly from PWRMON line of UC864-E/G/WD/WDU. Note that the TC7SZ07AE has open drain output; therefore the resistor R2 is mandatory. A power source of the internal interface voltage corresponding to the 2.6V CMOS high level is available at the VAUX pin on the connector.
PAGE 46
UC864-E/G/WD/WDU Hardware User Guide 1vv0300766a Rev.4 - 03/02/09 Careful approach is needed to avoid latch-up on UC864-E/G/WD/WDU and the use of this output line to power electronic devices must be avoided, especially for devices that generate spikes and noise such as switching level translators, micro controllers, failure in any of these condition can severely compromise the UC864-E/G/WD/WDU functionality. NOTE: The input lines working at 2.

In HSDPA (High Speed download Packet Access) mode(for UC864-E/G only), the downlink data speed rates up to 7.2Mbps.

Using a GPIO Pad as Input The GPIO pads, when used as inputs, can be connected to a digital output of another device and report its status, provided this device has interface levels compatible with the 2.6V CMOS levels of the GPIO. If the digital output of the device is connected with the GPIO input, the pad has interface levels different from the 2.6V CMOS.

Power Supply Influence After applying a signal with a different amplitude from suggested by the manufacturer, a performance change will follow, according to the rule “if resonance frequency fo increases, amplitude decreases”. Because resonance frequency depends on acoustic design and lowering the amplitude of the driving signal, the response bandwidth tends to become narrow, and vice versa.
