TOBY-L2 and MPCI-L2 series - System Integration Manual 1.4 Operating modes TOBY-L2 and MPCI-L2 series modules have several operating modes. The operating modes are defined in Table 5 and described in detail in Table 6, providing general guidelines for operation. General Status Operating Mode Definition Power-down Not-Powered Mode VCC or 3.3Vaux supply not present or below operating range: module is switched off. Power-Off Mode VCC or 3.
PAGE 22
TOBY-L2 and MPCI-L2 series - System Integration Manual Operating Mode Description Transition between operating modes Active-Mode Module is switched on with application interfaces enabled or not suspended: the module is ready to communicate with an external device by means of the application interfaces unless power saving configuration is enabled by AT+UPSV (see 1.9.1.4, 1.9.2.4 and u-blox AT Commands Manual [3]). When the module is switched on by an appropriate power-on event (see 1.6.
PAGE 23
TOBY-L2 and MPCI-L2 series - System Integration Manual 1.5 1.5.1 Supply interfaces Module supply input (VCC or 3.3Vaux) TOBY-L2 modules are supplied via the three VCC pins, and MPCI-L2 modules are supplied via the five 3.3Vaux pins. All supply voltages used inside the modules are generated from the VCC or the 3.3Vaux supply input by integrated voltage regulators, including the V_BCKP RTC supply, the V_INT generic digital interface supply, and the VSIM or UIM_PWR SIM interface supply.
PAGE 24
TOBY-L2 and MPCI-L2 series - System Integration Manual 1.5.1.2 VCC or 3.3Vaux current consumption in 2G connected-mode When a GSM call is established, the VCC or 3.3Vaux module current consumption is determined by the current consumption profile typical of the GSM transmitting and receiving bursts. The peak of current consumption during a transmission slot is strictly dependent on the RF transmitted power, which is regulated by the network (the current base station).
PAGE 25
TOBY-L2 and MPCI-L2 series - System Integration Manual When a GPRS connection is established, more than one slot can be used to transmit and/or more than one slot can be used to receive. The transmitted power depends on network conditions, which set the peak current consumption, but following the 3GPP specifications the maximum Tx RF power is reduced if more than one slot is used to transmit, so the maximum peak of current is not as high as can be in case of a 2G single-slot call.
PAGE 26
TOBY-L2 and MPCI-L2 series - System Integration Manual 1.5.1.3 VCC or 3.3Vaux current consumption in 3G connected mode During a 3G connection, the module can transmit and receive continuously due to the Frequency Division Duplex (FDD) mode of operation with the Wideband Code Division Multiple Access (WCDMA). The current consumption depends on output RF power, which is always regulated by the network (the current base station) sending power control commands to the module.
PAGE 27
TOBY-L2 and MPCI-L2 series - System Integration Manual 1.5.1.4 VCC or 3.3Vaux current consumption in LTE connected-mode During an LTE connection, the module can transmit and receive continuously due to the Frequency Division Duplex (FDD) mode of operation used in LTE radio access technology. The current consumption depends on output RF power, which is always regulated by the network (the current base station) sending power control commands to the module.
PAGE 28
TOBY-L2 and MPCI-L2 series - System Integration Manual 1.5.1.5 VCC or 3.3Vaux current consumption in cyclic idle/active mode (power saving enabled) The power saving configuration is by default disabled, but it can be enabled using the AT+UPSV command (see the u-blox AT Commands Manual [3]). When power saving is enabled, the module automatically enters the low power idle-mode whenever possible, reducing current consumption.
PAGE 29
TOBY-L2 and MPCI-L2 series - System Integration Manual 1.5.1.6 VCC or 3.3Vaux current consumption in fixed active-mode (power saving disabled) When power saving is disabled, the module does not automatically enter the low power idle-mode whenever possible: the module remains in active-mode. Power saving configuration is by default disabled. It can also be disabled using the AT+UPSV command (see u-blox AT Commands Manual [3] for detail usage).
PAGE 30
TOBY-L2 and MPCI-L2 series - System Integration Manual 1.5.2 RTC supply input/output (V_BCKP) The RTC supply V_BCKP pin is not available on MPCI-L2 series modules. The V_BCKP pin of TOBY-L2 series modules connects the supply for the Real Time Clock (RTC). A linear LDO regulator integrated in the Power Management Unit internally generates this supply, as shown in Figure 11, with low current capability (see the TOBY-L2 series Data Sheet [1]).
PAGE 31
TOBY-L2 and MPCI-L2 series - System Integration Manual 1.5.3 Generic digital interfaces supply output (V_INT) The generic digital interfaces supply V_INT pin is not available on MPCI-L2 series modules. The V_INT output pin of the TOBY-L2 series modules is connected to an internal 1.8 V supply with current capability specified in the TOBY-L2 series Data Sheet [1].
PAGE 32
TOBY-L2 and MPCI-L2 series - System Integration Manual 1.6 System function interfaces 1.6.1 Module power-on The PWR_ON input pin is not available on MPCI-L2 series modules. When the TOBY-L2 and MPCI-L2 series modules are in the not-powered mode (switched off, i.e. the VCC or 3.3Vaux module supply is not applied), they can be switched on as following:  Rising edge on the VCC or 3.3Vaux supply input to a valid voltage for module supply, starting from a voltage value lower than 0.
PAGE 33
TOBY-L2 and MPCI-L2 series - System Integration Manual Figure 14 shows the module power-on sequence from the not-powered mode, describing the following phases:  The external supply is applied to the VCC or 3.3Vaux module supply inputs, representing the start-up event.  The PWR_ON and the RESET_N or PERST# pins suddenly rise to high logic level due to internal pull-ups.  The V_BCKP RTC supply output is suddenly enabled by the module as VCC reaches a valid voltage value.
PAGE 34
TOBY-L2 and MPCI-L2 series - System Integration Manual 1.6.2 Module power-off TOBY-L2 series can be properly switched off by:  AT+CPWROFF command (see u-blox AT Commands Manual [3]). The current parameter settings are saved in the module’s non-volatile memory and a proper network detach is performed.
PAGE 35
TOBY-L2 and MPCI-L2 series - System Integration Manual Figure 15 describes the TOBY-L2 power-off sequence by means of AT+CPWROFF with the following phases:  When the +CPWROFF AT command is sent, the module starts the switch-off routine.  The module replies OK on the AT interface: the switch-off routine is in progress.
PAGE 36
TOBY-L2 and MPCI-L2 series - System Integration Manual 1.6.3 Module reset TOBY-L2 and MPCI-L2 series modules can be properly reset (rebooted) by:  AT+CFUN command (see u-blox AT Commands Manual [3]). MPCI-L2 series modules can be additionally properly reset (rebooted) by:  AT+CPWROFF command (see u-blox AT Commands Manual [3]): the behavior differs than TOBY-L2 series, as MPCI-L2 modules will reboot rather than remain switched off due to modules’ internal configuration.

PAGE 48
TOBY-L2 and MPCI-L2 series - System Integration Manual CTS signal behavior The module hardware flow control output (CTS line) is set to the ON state (low level) at UART initialization. If the hardware flow control is enabled, as it is by default, the CTS line indicates when the UART interface is enabled (data can be received): the module drives the CTS line to the ON state or to the OFF state when it is either able or not able to accept data from the DTE over the UART (for example see section 1.9.2.
PAGE 49
TOBY-L2 and MPCI-L2 series - System Integration Manual DSR signal behavior If AT&S1 is set, as it is by default, the DSR module output line is set by default to the OFF state (high level) at UART initialization. The DSR line is then set to the OFF state when the module is in command mode14 or in online command mode14 and is set to the ON state when the module is in data mode14.
PAGE 50
TOBY-L2 and MPCI-L2 series - System Integration Manual RI signal behavior The RI module output line is set by default to the OFF state (high level) at UART initialization. The RI line can notify an incoming call: the RI line is switched from the OFF state to the ON state with a 4:1 duty cycle and a 5 s period (ON for 1 s, OFF for 4 s, see Figure 21), until the DTE attached to the module sends the ATA string and the module accepts the incoming data call.
PAGE 51
TOBY-L2 and MPCI-L2 series - System Integration Manual 1.9.2.4 UART and power-saving The power saving configuration is controlled by the AT+UPSV command (for the complete description, see the u-blox AT Commands Manual [3]). When power saving is enabled, the module automatically enters low power idle-mode whenever possible, and otherwise the active-mode is maintained by the module (see section 1.4 for definition and description of module operating modes referred to in this section).
PAGE 52
TOBY-L2 and MPCI-L2 series - System Integration Manual AT+UPSV HW flow control RTS line DTR line Communication during idle-mode and wake up 3 Enabled (AT&K3) ON ON Data sent by the DTE is correctly received by the module. Data sent by the module is correctly received by the DTE. 3 Enabled (AT&K3) ON OFF Data sent by the DTE is buffered by the DTE and will be correctly received by the module when it is ready to receive data (when the UART is enabled).
PAGE 53
TOBY-L2 and MPCI-L2 series - System Integration Manual The CTS output line is driven to the ON or OFF state when the module is either able or not able to accept data from the DTE over the UART: Figure 23 illustrates the CTS output line toggling due to paging reception and data received over the UART, with AT+UPSV=1 configuration. Data input CTS OFF CTS ON time [s] ~9.
PAGE 54
TOBY-L2 and MPCI-L2 series - System Integration Manual The module automatically enters the low power idle-mode whenever possible but it wakes up to active-mode according to any required activity related to the network (e.g. for the periodic paging reception described in section 1.5.1.5, or for any other required RF signal transmission or reception) or any other required activity related to the functions / interfaces of the module.
PAGE 55
TOBY-L2 and MPCI-L2 series - System Integration Manual Figure 25 shows the case where in addition to the wake-up character further (valid) characters are sent. The wake up character wakes-up the module UART. The other characters must be sent after the “wake up time” of ~5 ms. If this condition is satisfied, the module (DCE) recognizes characters. The module will disable the UART after 2000 GSM frames from the latest data reception. UART DCE UART is enabled for 2000 GSM frames (~9.
