  • Page 16: Power On/Off Operation

    3.4.1 Turning the G610 on When the G610 is powered off, the PMU operates at low power mode, with only the RTC timer active. G610 will power on again when the POWER_ON signal is falling edge. Asserting the POWER_ON signal low for a minimum of 800 milliseconds will turn G610 on in default power on mode.

  • Page 18: Turning The G610 Off

    3.4.2.1 Turning the G610 off Using POWER_ON The POWER_ON signal is set high using an internal pull up resistor when power is applied to G610. When the POWER_ON signal is falling edge and keeping low for a minimum of 3 seconds will turn G610 off. This will initiate a normal power-off process, which includes disabling of all applications interfaces (UART, SIM card, audio, etc.) and logout the network connection.

  • Page 19: Sleep Mode

    3.5.1 Activating Sleep Mode By default, the G610 powers on in Idle Mode. The ATS24 default is 0. In this mode the G610 interfaces and features are functional and the module is fully active. Sleep mode is activated by the ATS24 command. Such as ATS24 would be activated Sleep mode at soon.

  • Page 20: Terminating Sleep Mode

    During Sleep mode, G610 continues monitoring the GSM network for any incoming data, message or voice calls. When G610 receives an indication from the network that an incoming voice call, message or data is available, it automatically wakes up from Sleep mode to alert the application. When G610 wakes up to Idle mode all its interfaces are enabled.
  • Page 21 2) The G610 serial interface is set NONE FLOW (AT+IFC=0,0)(The default value) Most of serial data from DTE to G610 will be lost when the G610 serial interface is set NONE FLOW (default value). The G610 will receive the data and make responses after it go back to Idle mode.

  • Page 22: Real Time Clock

    When the main power supply and VBACKUP is disconnected from G610, the RTC timer will reset and the current time and date will be lost. On the next G610 power-up the time and date will need to be set again automatically or manually.

  • Page 23: Rtc Application

    G610 includes one completely independent serial communications interfaces (UART). The G610 UART is a standard 8-signal bus. This UART is used for all the communications with G610 - AT commands interface, GPRS/EGPRS data and CSD data, programming and software upgrades.

    GSM SIM card. The G610 does not incorporate an on-board SIM card tray for SIM placement. The SIM must be located on the user application board, external to the G610. The G610 SIM interface includes all the necessary signals, which are routed to the interface connector, for a direct and complete connection to an external SIM.

  • Page 26: Sim Design Guidelines

    3.8.2 SIM Design Guidelines The SIM interface and signals design is extremely important for proper operation of G610 and the SIM card. There are several design guidelines that must be followed to achieve a robust and stable design that meets the required standards and regulations.

    The G610 incorporates a regulated voltage output VDD. The regulator provides a 2.85V output for use by the customer application. This regulator can source up to 10mA of current to power any external digital circuits. When the G610 started up by power on signal, The VDD is output. So it can be Illustrating module start up. Note: The VDD regulator is powered from the G610's main power supply, and therefore any current sourced through this regulator originates from the G610 BATT supply.
