8 / 30 page  SARA-N2 series - Data Sheet UBX-15025564 - R16 Interfaces Page 8 of 30 2 Interfaces 2.1 Power management 2.1.1 Module supply input (VCC) SARA-N2 series modules must be supplied through the VCC pins by a DC power supply with nominal voltage of 3.6 V. Voltage must be stable during module operation, taking into account that the current drawn from VCC pins may vary significantly based on the power consumption profile of the NB-IoT system. 2.1.2 Digital I/O interfaces supply output (V_INT) SARA-N2 series modules provide an internally generated supply rail output (V_INT) operating at 1.8 V. This can be used in place of an external discrete regulator to supply external digital interfaces. The voltage level present at the V_INT pin depends on the module operating mode: When the radio is off, the voltage level is kept low (i.e. 0 V) When the radio is on, the voltage level is maintained high (i.e. 1.8 V) ☞ Provide a test point connected to the V_INT pin for diagnostic purpose. 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-N2 series modules. 2.2.1.1 Antenna detection (ANT_DET) The ANT_DET pin is an Analog to Digital Converter (ADC) input used to sense the antenna presence evaluating the resistance from the ANT pin to GND by means of an external antenna detection circuit implemented on the application board. ☞ The antenna detection (ANT_DET) interface is not supported by "02" product versions. 2.3 System functions 2.3.1 Module power-on SARA-N2 series modules can be switched on by a rising edge voltage applied to the VCC pins. See section 4.2.2 for more details about the valid supply voltage range. 2.3.2 Module power-off An abrupt under-voltage shutdown occurs on SARA-N2 series modules when the VCC supply voltage drops below the operating range minimum limit (see section 4.2.2). 2.3.3 Module reset SARA-N2 series modules can be reset applying a low voltage level on the RESET_N input pin, which is normally set high by an internal pull-up, for a valid time period (see the section 4.2.5). This causes an “external” or “hardware” reset of the module. ☞ Provide a test point connected to the RESET_N pin for diagnostic purposes. |
