GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 NOTE: Reserved pins must not be connected. NOTE: RTS must be connected to the GND (on the module side) if flow control is not used. NOTE: If not used, almost all pins must be left disconnected. The only exceptions are the 2 following pins : 4.1.1.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 5. Hardware Commands 5.1. Turning ON the GC864-QUAD / PY To turn the GC864-QUAD / PY on, the pad ON# must be tied low for at least 1 second and then released. A pulse duration less than 1 second should also start the power on procedure, but this is not guaranteed. The maximum current that can be drained from the ON# pad is 0,1 mA. A simple circuit to do it is: TIP: To check if the device has powered on, the hardware line PWRMON must be monitored.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 For example: 1- Let us assume you need to drive the ON# pad with a totem pole output of a +3/5 V microcontroller (uP_OUT1): 2- Let us assume you need to drive the ON# pad directly with an ON/OFF button: A flow chart with proper turn on procedure is detailed below: Reproduction forbidden without Telit Communications S.p.A’s. written authorization - All Rights Reserved.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 5.2. Turning OFF the GC864-QUAD / PY Turning off of the device can be done in three ways: • by software command (see GC864-QUAD / PY Software User Guide) • by tying low pin ON# Either ways, the device issues a detach request to network informing that the device will not be reachable any more. To turn OFF the GC864 via pin ON#, this must be tied low for at least 1s and then released. The same circuitry and timing for the power on shall be used.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 TIP: To check if the device has powered off, the hardware line PWRMON must be monitored. When PWRMON goes low, then the device has powered off. 5.2.1. Hardware Unconditional Restart WARNING: The hardware unconditional Restart must not be used during normal operation of the device since it does not detach the device from the network.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 In the following flow chart is detailed the proper restart procedure: For example: 1- Let us assume you need to drive the RESET# pad with a totem pole output of a +3/5 V microcontroller (uP_OUT2): Reproduction forbidden without Telit Communications S.p.A’s. written authorization - All Rights Reserved.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 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 following requirements and guidelines for a proper design. 6.1. Power Supply Requirements POWER SUPPLY Nominal Supply Voltage Max Supply Voltage Supply voltage range SW rel. 7.02.xx4 or older 3.8 V 4.2 V 3.4 V - 4.2 V SW rel. 7.03.x00 or newer 3.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 The GSM system is made in a way that the RF transmission is not continuous but it is packed into bursts at a base frequency of about 216 Hz. The relative current peaks can be as high as about 2A. Therefore the power supply has to be designed in order to withstand with these current peaks without big voltage drops; this means that both the electrical design and the board layout must be designed for this current flow.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 • A Bypass low ESR capacitor of adequate capacity must be provided in order to cut the current absorption peaks close to the GC864-QUAD / PY, a 100μF tantalum capacitor is usually suited. • Make sure the low ESR capacitor on the power supply output (usually a tantalum one) is rated at least 10V. • A protection diode must be inserted close to the power input, in order to save the GC864-QUAD / PY from power polarity inversion.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 6.2.1.2. +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 GC864-QUAD/PY.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 An example of switching regulator with 12V input is in the schematic below (split in 2 parts): Reproduction forbidden without Telit Communications S.p.A’s. written authorization - All Rights Reserved.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 6.2.1.3. Battery Source Power Supply Design Guidelines The desired nominal output for the power supply is 3.8V and the maximum voltage allowed is 4.2V (4.5 if using SW release 7.03.x00 or newer). A single 3.7V Li-Ion cell battery type is suited for supplying the power to the Telit GC864-QUAD/PY module. CAUTION: The three cells Ni/Cd or Ni/MH 3,6 V Nom.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 During the fast charge phase the process proceeds with a current limited charging; this current limit depends on the required time for the complete charge and from the battery pack capacity. During this phase the voltage across the battery terminals still raises but at a lower rate. Once the battery voltage reaches its maximum voltage then the process goes into its third state: Final charging.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 As you can see, the charging process is not a trivial task to be done; moreover all these operations must start only if battery temperature is inside a charging range, usually 5°C – 45°C.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 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. Considering the very low current during idle, especially if Power Saving function is enabled, it is possible to consider from the thermal point of view that the device absorbs current significantly only during calls.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 6.2.4. • The PCB traces from the input connector to the power regulator IC must be wide enough to ensure no voltage drops occur when the 2A current peaks are absorbed. Note that this is not made in order to save power loss but especially to avoid the voltage drops on the power line at the current peaks frequency of 216 Hz that will reflect on all the components connected to that supply, introducing the noise floor at the burst base frequency.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 • In abnormal conditions, the maximum RF output power is up to 34 dBm for few seconds. For this particular application, we recommend the customer to involve TTSC (Telit Technical Support Center) in the design phase of the application.

Antenna The antenna connection and board layout design are the most important part in the full product design and they strongly reflect on the product overall performances, hence read carefully and follow the requirements and the guidelines for a proper design. 7.1.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 7.2. GSM Antenna – Installation Guidelines • Install the antenna in a place covered by the GSM signal. • The Antenna must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter; • Antenna shall not be installed inside metal cases • Antenna shall be installed also according Antenna manufacturer instructions.

GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 8.1. Reset Signal Signal RESET Function Phone reset I/O I PIN Number 54 RESET is used to reset the GC864-QUAD / PY modules. Whenever this signal is pulled low, the GC864-QUAD / PY is reset. When the device is reset it stops any operation. After the release of the reset GC864-QUAD / PY is unconditionally shut down, without doing any detach operation from the network where it is registered.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 9. Serial Ports The serial port on the Telit GC864-QUAD/PY is the core of the interface between the module and OEM hardware. 2 serial ports are available on the module: • • 9.1. MODEM SERIAL PORT MODEM SERIAL PORT 2 (DEBUG) MODEM SERIAL PORT Several configurations can be designed for the serial port on the OEM hardware, but the most common are: • RS232 PC com port • microcontroller UART @ 2.

GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 TIP: For a minimum implementation, only the TXD and RXD lines can be connected, the other lines can be left open provided a software flow control is implemented. TIP: In order to avoid noise or interferences on the RXD lines it is suggested to add a pull up resistor (100KΩ to 2.8V) Reproduction forbidden without Telit Communications S.p.A’s. written authorization - All Rights Reserved.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 9.2. RS232 Level Translation In order to interface the Telit GC864-QUAD/PY with a PC com port or a RS232 (EIA/TIA-232) application a level translator is required.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 An example of level translation circuitry of this kind is: The RS232 serial port lines are usually connected to a DB9 connector with the following layout: Reproduction forbidden without Telit Communications S.p.A’s. written authorization - All Rights Reserved.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 9.3. 5V UART Level Translation If the OEM application uses a microcontroller with a serial port (UART) that works at a voltage different from 2.8 – 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.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 TIP: This logic IC for the level translator and 2.8V pull-ups (not the 5V one) can be powered directly from VAUX line of the GC864-QUAD / PY. Note that the TC7SZ07AE has open drain output; therefore the resistor R2 is mandatory.

GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 10.2. Electrical Characteristics TIP: Being the microphone circuitry the more noise sensitive, its design and layout must be done with particular care. Both microphone paths are balanced and the OEM circuitry must be balanced designed to reduce the common mode noise typically generated on the ground plane. However the customer can use the unbalanced circuitry for particular application. 10.2.1.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 10.2.2. Output Lines Characteristics TIP: We suggest driving the load differentially from both output drivers, thus the output swing will double and the need for the output coupling capacitor avoided. However if particular OEM application needs also a Single Ended circuitry can be implemented, but the output power will be reduced four times .

GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 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 11.8.1 Frequency Behavior The frequency behavior represents the effectiveness of the reproduction of the applied signals.
GC864 Hardware User Guide 1vv0300733 Rev.12 – 2009-06-04 11.8.4. Working Current Influence In the component data sheet you will find the value of MAX CURRENT that represents the maximum average current that can flow at nominal voltage without current limitation. In other words it is not the peak current, which could be twice or three times higher. If driving circuitry does not support these peak values, the SPL will never reach the declared level or the oscillations will stop. 11.9.
