  • Page 20: Supply Interfaces

    TOBY-L2 and MPCI-L2 series - System Integration Manual Supply interfaces 1.5.1 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 21 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.
  • Page 22 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 23 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 again on output RF power, which is always regulated by network commands.

The current consumption is strictly dependent on the transmitted RF output power, which is always regulated by network commands.
  • Page 25 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 26 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 27: 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 28: 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]. This supply is internally generated by a switching step- down regulator integrated in the Power Management Unit and it is internally used to source the generic digital I/O interfaces of the TOBY-L2 module, as described in Figure 12.

As described in Figure 13, the TOBY-L2 series PWR_ON input is equipped with an internal active pull-up resistor to the VCC module supply: the PWR_ON input voltage thresholds are different from the other generic digital interfaces.
  • Page 30 The internal reset signal is held low: the baseband core and all the digital pins are held in the reset state. The reset state of all the digital pins is reported in the pin description table of TOBY-L2 Series Data Sheet [1].

  • Page 31: Module Power-Off

    (see the u-blox AT Commands Manual [3]), and then the 3.3Vaux supply can be removed. An abrupt hardware shutdown occurs on TOBY-L2 series modules when a low level is applied on the RESET_N pin for a specific time period. In this case, the current parameter settings are not saved in the module’s non-volatile memory and a proper network detach is not performed.
  • Page 32 Operational → Tristate ~2.5 s ~5 s Figure 15: TOBY-L2 series power-off sequence description The Internal Reset signal is not available on a module pin, but the application can monitor the V_INT pin to sense the end of the power-off sequence.

  • Page 33: Module Reset

    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.

    The ANT1 represents the primary RF input/output for transmission and reception of LTE/3G/2G RF signals. The ANT1 pin of TOBY-L2 series modules has a nominal characteristic impedance of 50  and must be connected to the primary Tx / Rx antenna through a 50  transmission line to allow proper RF transmission and reception.

Frequency Range See the TOBY-L2 series Data Sheet [1] and the The required frequency range of the antenna connected MPCI-L2 series Data Sheet [2] to ANT1 port depends on the operating bands of the used cellular module and the used mobile network.
