2 Interfaces

2.1 Power management

2.1.1 Module supply input (VCC)

SARA-G3 modules must be supplied through the three VCC pins by a DC power supply. Voltages must be stable: during operation, the current drawn from VCC can vary by some order of magnitude, especially due to the surging consumption profile of the GSM system (described in the SARA-G3 / SARA-U2 series system integration manual [2]). It is important that the system power supply circuit is able to support peak power.

SARA-G3 modules product versions “02” onwards provide separate supply inputs over the three VCC pins:

• VCC pins #52 and #53 represent the supply input for the internal RF power amplifier, demanding

most of the total current drawn of the module when RF transmission is enabled during a voice/data call

• VCC pin #51 represents the supply input for the internal baseband Power Management Unit and

the internal transceiver, demanding minor part of the total current drawn of the module when RF transmission is enabled during a voice/data call

2.1.2 RTC supply input/output (V_BCKP)

V_BCKP is the Real Time Clock (RTC) supply of SARA-G3 modules. When VCC voltage is within the

valid operating range, the internal Power Management Unit (PMU) supplies the RTC and the same supply voltage is available on V_BCKP pin. If the VCC voltage is under the minimum operating limit (e.g. during not powered mode), the V_BCKP pin can externally supply the RTC.

2.1.3 Digital I/O interfaces supply output (V_INT)

SARA-G3 modules provide an internally generated supply rail output for digital interfaces (V_INT). This can be used in place of an external discrete regulator to supply pull-up resistors on the DDC interface. This optimizes the bill of material for various applications, e.g. with u-blox positioning modules operating at 1.8 V.

2.2 Antenna

2.2.1 Antenna RF interface (ANT)

The ANT pin has an impedance of 50  and provides the RF antenna interface of SARA-G3 modules.

2.2.2 Antenna detection (ANT_DET)

The ANT_DET pin is an Analog to Digital Converter (ADC) input provided only by SARA-G340 and SARA-G350 modules to sense the antenna presence (as optional feature), evaluating the resistance from the ANT pin to GND by means of an external antenna detection circuit implemented on the application board. For more details, see the SARA-G3 / SARA-U2 series system integration manual [2] and the u-blox AT commands manual [1], +UANTR.

2.3 System functions

2.3.1 Module power-on (PWR_ON)

SARA-G3 modules can be switched on in one of the following ways:

• Rising edge on the VCC pin to a valid voltage for module supply, i.e. applying module supply

• Low level on the PWR_ON input pin, i.e. forcing the pin (normally high with external pull-up) to a

low level for a valid time period (see section 4.2.7). The PWR_ON pin requires an external pull-up resistor to set its value to logic high and may not be left floating

• RTC alarm, i.e., pre-programmed scheduled time (see the u-blox AT commands manual [1],

AT+CALA)

☞ SARA-G300 and SARA-G310 cannot be switched on with RTC alarm.

2.3.2 Module power-off

SARA-G3 modules can be properly switched off, with storage of current settings and network detach, by:

• AT+CPWROFF command

An abrupt under-voltage shutdown occurs on SARA-G3 modules when the VCC supply drops below the extended operating range minimum limit, but in this case it is not possible to perform the storing of the current parameter settings in the module’s non-volatile memory as well as the proper network detach.

An over-temperature or an under-temperature shutdown occurs on SARA-G3 modules when the temperature measured within the cellular module reaches the dangerous area, if the optional Smart Temperature Supervisor feature is enabled and configured by the dedicated AT command. For more details, see the SARA-G3 / SARA-U2 series system integration manual [2] and the u-blox AT commands manual [1], +USTS AT command.

2.3.3 Module reset (RESET_N)

SARA-G3 modules can be properly reset (rebooted), with storage of current parameter settings in the module’s non-volatile memory and proper network detach, in this way:

• AT+CFUN command (see the u-blox AT commands manual [1]). This causes an “internal” or

“software” reset of the module.

An abrupt “external” or “hardware” reset occurs when a low level is applied to the RESET_N pin, which is normally set high by an internal pull-up, for a valid time period (see section 4.2.8), but in this case it is not possible to perform the storing of the current parameter settings as well as the proper network detach.

2.3.4 External 32 kHz signal input (EXT32K)

SARA-G300 and SARA-G310 provide the EXT32K input pin that must be fed by a proper 32 kHz signal to furnish the reference clock for the RTC, allowing very low power idle-mode and RTC functions support. See section 4.2.9 for detailed electrical specifications for the 32 kHz signal.

SARA-G340 and SARA-G350 do not provide the EXT32K input pin. An internal 32 kHz oscillator automatically generates the reference clock for the RTC, allowing very low power idle-mode and RTC functions support.

SARA-G3 series - Data sheet

UBX-13000993 - R23 Interfaces Page 13 of 47 C1-Public

2.3.5 Internal 32 kHz signal output (32K_OUT)

SARA-G300 and SARA-G310 provide the 32K_OUT output pin which gives a 32 kHz reference signal suitable only to feed the EXT32K input pin of SARA-G300 / SARA-G310 modules, furnishing the reference clock for the RTC, allowing low power idle-mode and RTC functions support with modules switched on.

SARA-G340 and SARA-G350 do not provide the 32K_OUT output; there is no EXT32K input on these modules.

2.4 SIM

2.4.1 (U)SIM interface

A (U)SIM card interface is available via the VSIM, SIM_IO, SIM_CLK, SIM_RST pins of SARA-G3 series modules: the high-speed SIM/ME interface is implemented as well as the automatic detection of the required SIM supporting voltage.

Both 1.8 V and 3 V SIM types are supported: activation and deactivation with automatic voltage switch from 1.8 V to 3 V are implemented, according to ISO-IEC 7816-3 Specifications. The SIM driver supports the PPS procedure for baud-rate selection, according to the values proposed by the SIM Card.

2.4.2 SIM card detection (SIM_DET)

☞ Not supported by SARA-G300-00S and SARA-G310-00S modules.

The SIM_DET pin of SARA-G3 modules is a digital input provided to sense the SIM card presence (as an optional feature), when it is properly connected to the mechanical switch of the SIM card holder (for more details, see the SARA-G3 / SARA-U2 series system integration manual [2]).

2.5 Serial interfaces

SARA-G3 modules provide the following serial communication interfaces:

• UART interface: 9-wire unbalanced 1.8 V asynchronous serial interface supporting

o AT command mode o Data mode and Online command mode

o MUX functionality, including dedicated GNSS tunneling virtual channel
