Hardware Commands Auto-Turning ON the GL865 To Auto-turn on the GL865, the power supply must be applied on the power pins VBATT and VBATT_PA, after 1000 m-seconds, the V_AUX / PWRMON pin will be at the high logic level and the module can be consider fully operating. When the power supply voltage is lower than 3.4V, after 4000 mseconds, the V_AUX / PWRMON pin will be at the high logic level and the module can be consider fully operating.
GL865 Hardware User Guide 1vv0300910 Rev.1 – 2011-07-22 NOTE: The power supply on the pins VBATT and VBATT_PA must be applied at the same time or for the special application in the first apply the VBATT_PA and in second time apply VBATT, never vice versa in this case can be damage the unit. NOTE: In order to avoid a back powering effect it is recommended to avoid having any HIGH logic level signal applied to the digital pins of the GL865 when the module is powered OFF or during an ON/OFF transition.
GL865 Hardware User Guide 1vv0300910 Rev.1 – 2011-07-22 5.2. Turning OFF the GL865 Turning off of the device can be done in two ways: • General turn OFF • Processor turn OFF General turn OFF – disconnect the power supply from the both power pins VBATT and VBATT_PA at the same time. In this case all parts of the module are in OFF condition, any power consumption is present.

GL865 Hardware User Guide 1vv0300910 Rev.1 – 2011-07-22 6. Power Supply The power supply circuitry and board layout are a very important part in the full product design and they strongly reflect on the product overall performances, hence read carefully the requirements and the guidelines that will follow for a proper design. 6.1.
GL865 Hardware User Guide 1vv0300910 Rev.1 – 2011-07-22 6.2. Power Consumption The GL865 power consumptions are: GL 865 Mode Average (mA) SWITCHED OFF Switched Off <5uA Switched Off with <650uA AT#SYSHALT Mode description Module power supplied only on VBATT_PA pin, the VBATT pin is not power supplied.

GL865 Hardware User Guide 1vv0300910 Rev.1 – 2011-07-22 NOTE: The electrical design for the Power supply should be made ensuring it will be capable of a peak current output of at least 2 A. 6.3. General Design Rules The principal guidelines for the Power Supply Design embrace three different design steps: • the electrical design • the thermal design • the PCB layout. 6.3.1.
GL865 Hardware User Guide 1vv0300910 Rev.1 – 2011-07-22 An example of linear regulator with 5V input is: 6.3.1.2. + 12V input Source Power Supply Design Guidelines The desired output for the power supply is 3.8V, hence due to the big difference between the input source and the desired output, a linear regulator is not suited and shall not be used. A switching power supply will be preferable because of its better efficiency especially with the 2A peak current load represented by the GL865.
GL865 Hardware User Guide 1vv0300910 Rev.1 – 2011-07-22 A protection diode should be inserted close to the power input, in order to save the GL865 from power polarity inversion. This can be the same diode as for spike protection. An example of switching regulator with 12V input is in the below schematic (split in 2 parts): 6.3.1.3. Battery Source Power Supply Design Guidelines Reproduction forbidden without Telit Communications S.p.A.
GL865 Hardware User Guide 1vv0300910 Rev.1 – 2011-07-22 The desired nominal output for the power supply is 3.8V and the maximum voltage allowed is 4.2V, hence a single 3.7V Li-Ion cell battery type is suited for supplying the power to the Telit GL865 module. WARNING: The three cells Ni/Cd or Ni/MH 3,6 V Nom. battery types or 4V PB types MUST NOT BE USED DIRECTLY since their maximum voltage can rise over the absolute maximum voltage for the GL865 and damage it.
GL865 Hardware User Guide 1vv0300910 Rev.1 – 2011-07-22 6.3.2. Thermal Design Guidelines The thermal design for the power supply heat sink should be done with the following specifications: See para 7.2 Power Consumption NOTE: The average consumption during transmissions depends on the power level at which the device is requested to transmit by the network. The average current consumption hence varies significantly.
GL865 Hardware User Guide 1vv0300910 Rev.1 – 2011-07-22 6.3.3. Power Supply PCB layout Guidelines As seen on the electrical design guidelines the power supply shall 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.
GL865 Hardware User Guide 1vv0300910 Rev.1 – 2011-07-22 The power supply input cables should be kept separate from noise sensitive lines such as microphone/earphone cables. Reproduction forbidden without Telit Communications S.p.A.

GL865 Hardware User Guide 1vv0300910 Rev.1 – 2011-07-22 An example of level translation circuitry of this kind is: The example is done with a MAXIM MAX3237 Transceiver that could accept supply voltages of 3V DC. Not exceeded with supply voltage higher then 3.1VDC because this is the higher voltage limit of module’s inputs. NOTE: In this case Vin has to be set with a value compatible with the logic levels of the module. (Max 3.1V DC) Reproduction forbidden without Telit Communications S.p.A.
GL865 Hardware User Guide 1vv0300910 Rev.1 – 2011-07-22 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 GL865 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.
GL865 Hardware User Guide 1vv0300910 Rev.1 – 2011-07-22 9.4. 5V UART level translation If the OEM application uses a microcontroller with a serial port (UART) that works at a voltage different from 2.8 - 3V, then a circuitry has to be provided to adapt the different levels of the two set of signals. As for the RS232 translation there are a multitude of single chip translators.
GL865 Hardware User Guide 1vv0300910 Rev.1 – 2011-07-22 NOTE: The input lines working at 2.8VCMOS can be pulled-up with 47KΩ In case of reprogramming of the module has to be considered the use of the RESET line to start correctly the activity. The preferable configuration is having an external supply for the buffer.

GL865 Hardware User Guide 1vv0300910 Rev.1 – 2011-07-22 Drawing of the Magnetic Buzzer. The disk and diaphragm are attracted to the core by the magnetic field. When an oscillating signal is moved through the coil, it produces a fluctuating magnetic field which vibrates the diaphragm at a frequency of the drive signal. Thus the sound is produced relative to the frequency applied. Diaphragm movement. 11.7.1.
GL865 Hardware User Guide 1vv0300910 Rev.1 – 2011-07-22 Because resonance frequency depends on acoustic design, by lowering the amplitude of the driving signal the response bandwidth tends to become narrow, and vice versa.
