13. 2 SIM Design Guidelines The SIM interface and signals design is extremely important for proper operation of module 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 e The SIM should be located and its signals should be routed away from any possible EMI sources such as the RF antenna and digital switching signals e The SIM interface signals length should not exceed 100 mm between the module interface connector and the SIM tray This is to meet with EMC regulations and improve signal integrity e To avoid crosstalk between the SIM clock and data signals SIM_CLK and SIM_DATA it is recommended to rout them separately on the application board and preferably isolated by a surrounding ground plane e The SIM card signals should be protected from ESD using very low capacitance protective elements zener diodes etc The recommended part no of ESD isAVR M1005C270MAAB TDk We also recommended the ESD component should layout with SIM hold closely 3 9 I2C Interface G610 supports 12C interface two lines one serial data line SDA one serial clock line SCL Features e Reaches up to 400kbit s e Open drain output e Generate start bit and stop bit automatically e Response and confirm automatically e Application hardware DC protocol Pin No Signal Name Description 36 SDA GPIO19 12C data signal 37 SCL GP
14. 5 3 Terminating Sleep Mode Terminating the Sleep mode or wake up is defined as the transition of the module operating state from Sleep mode to Idle mode There are several ways to wake up module from Sleep mode as described below During Sleep mode the G610 internal clocks and circuits are disabled in order to minimize power consumption When terminating the Sleep mode and switching to Idle mode G610 requires a minimal delay time to reactivate and stabilize its internal circuits before it can respond to application data This delay is typically of 5ms The delay guarantees that data on the serial interface is not lost or misinterpreted 3 5 3 1 Temporary Termination of Low Power Mode Temporary termination of Sleep mode occurs when module switches from Sleep mode to Idle mode for a defined period and then returns automatically to Sleep mode Low power mode may be terminated temporarily by several sources some of which are user initiated and others are initiated by the system G610 Hardware User Manual Page 19 of 41 FIDCCON gt Incoming Network Data During Sleep mode module continues monitoring the GSM network for any incoming data message or voice calls When module 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 module wakes up to Idle mode all its interfaces are enabled gt DTR_N Signal DTR_N
