1.3 Pin-out
Table 3Table 3 lists the pin-out of the SARA-G3 modules, with pins grouped by function.
VCC pins are internally connected each other.
VCC supply circuit affects the RF performance
and compliance of the device integrating the
module with applicable required certification
schemes.
See section 1.5.11.5.1 for functional description
and requirements for the VCC module supply.
See section 2.1.12.1.1 for external circuit design-

GND pins are internally connected each other.
External ground connection affects the RF and
thermal performance of the device.
See section 1.5.11.5.1 for functional description.

Real Time Clock
supply
input/output
V_BCKP = 2.3 V (typical) generated by
internal regulator when valid VCC supply is
present.
See section 1.5.21.5.2 for functional description.
See section 2.1.22.1.2 for external circuit design-
in.
Digital Interfaces
supply output
V_INT = 1.8 V (typical) generated by internal
regulator when the module is switched on.
See section 1.5.31.5.3 for functional description.
See section 2.1.32.1.3 for external circuit design-
in.
High input impedance: input voltage level has to
be properly fixed, e.g. adding external pull-up.
See section 1.6.11.6.1 for functional description.
See section 2.2.12.2.1 for external circuit design-
in.
A series Schottky diode is integrated in the
module as protection, and then an internal 10
k pull-up resistor to V_INT is provided.
See section 1.6.31.6.3 for functional description.
See section 2.2.22.2.2 for external circuit
design-in.
Input for RTC reference clock, needed to enter
the low power idle-mode and provide RTC
functions.
See section 1.6.41.6.4 for functional description.
See section 2.2.32.2.3 for external circuit
design-in.
