1 Functional description
1.1 Overview
SARA-N2 series modules are a Narrow Band Internet of Things (NB -IoT) solution coming in the miniature SARA LGA form factor (16.0 x 26.0 mm, 96-pin). The modules offer IoT data communication over an extended operating temperature range of –40 °C to +85 °C, with extremely low power consumption. The SARA-N2 series includes variants supporting single-band and dual -band communication and designed to operate in the frequency range of the LTE bands 5, 8, 20 and 28. These products are ideally suited to battery -powered IoT applications characterized by occasional communications of small amounts of data. SARA-N2 series modules are the optimal choice for IoT devices designed to operate in locations with a very limited coverage and requiring low energy consumption to permit a very long operating life of the prim ary batteries. Examples of applications include and are not limited to: smart grids, smart metering, telematics, street lighting, environmental monitoring and control, security and asset tracking.

1.5 AT command support
The SARA-N2 series modules support AT commands according to the 3GPP standards, plus the u-blox AT command extensions. ☞ For the complete list of all supported AT commands and their syntax, see the SARA-N2 series AT Commands Manual [1].
1.6 Supported features
Network Indication Pin configured to indicate the network status: registered home network, registered roaming, data call enabled, no service. The feature can be enabled through the +UGPIOC AT command. Embedded UDP stack Embedded UDP/IP stack for UDP sockets.to establish a transparent end-to-end communication. CoAP The Constrained Application Protocol (CoAP) is a datagram-based client/server application protocol for devices on the constrained network (e.g. low overhead, low-power), designed to easily translate to HTTP for simplified integration with the web. CoAP clients can use the GET, PUT, POST and DELETE methods using requests and responses with a CoAP server. Release Assistance The Release Assistance feature introduced in 3GPP Rel.13 allows the module to request for the RRC connection to be dropped as soon as the message has been received by the network. This feature allows a reduction in the module power consumption. Self-Registration Support of Self-Registration feature according to CTCC (China Telecom Corporation) and CUCC (China Unicom Corporation) requirements. Firmware update Over AT commands (FOAT) Firmware module update over AT command interface. The feature can be enabled and configured through the +UFWUPD AT command. Firmware update Over The Air (FOTA) The Firmware over-the-air (FOTA) component uses the CoAP context to download a FW update package from a dedicated server. Power Saving Mode (PSM) The Power Saving Mode (PSM) feature, defined in 3GPP Rel.13, allows further reduction of the module current consumption maximizing the amount of time a device can remain in extremely low power deep sleep mode during periods of data inactivity. It can be activated and configured by the +CPSMS AT command. Deep-sleep mode The SARA-N2 series modules enters in extremely low power deep sleep mode whenever possible, using the internal 32 kHz clock to maintaining an extremely low current consumption. This optimizes the life time of the battery pack used to supply the system eDRX Extended mode DRX, based on 3GPP Rel.13, reduces the amount of signaling overhead decreasing the frequency of scheduled measurements and/or transmissions performed by the module. This in turn leads to a reduction in the module power consumption while maintaining a perpetual connection with the base station Coverage Enhancement Coverage Enhancements Modes introduced in 3GPP Rel.13 for the NB-IoT system improve the cell signal penetration allowing a 20 dB coverage enhancement over standard GSM systems.

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 externa l 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 p ull-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.

2.4 SIM interface
A SIM card interface is provided by the VSIM, SIM_IO, SIM_CLK, and SIM_RST pins of SARA-N2 series modules, supporting 1.8 V SIM card/chip types.
2.5 Serial interfaces
2.5.1 Asynchronous serial interface (UART)
The UART interface is a 5-wire unbalanced asynchronous serial interface available for communication with an application host processor (AT commands and data communication) and for FW upgrade. The main characteristics of the interface are the following: Serial port with RS-232 functionality working at the VCC voltage domain (0 V for low data bit or ON state and ~3.6 V, i.e. VCC, for high data bit or OFF state) Data lines (RXD as module data output, TXD as module data input) Hardware flow control lines (CTS as module output, RTS as module input) The following baud rates are supported: 4800, 9600 (default baud rate), 57600 and 115200 b/s. Fixed frame format: 8N1 (8 data bits, no parity, 1 stop bit) The CTS line can be configured as RING indicator, to signal an incoming message received by the module or an URC event, or as Network status indicator (for more details see section 2.6 and the u-blox SARA-N2 series AT Commands Manual [1], +URING, +UGPIOC AT commands). ☞ For FW upgrade purposes, connect a test point to the RXD and TXD pins. ☞ Hardware flow control function is not supported by the "02" product versions.
2.5.2 Secondary asynchronous serial interface (Secondary UART)
The secondary UART interface is a 2 -wire unbalanced asynchronous serial interface available for diagnostic purpose, to capture trace diagnostic logs delivered by the module. The main characteristics of the interface are: Serial port with RS-232 functionality working at the V_INT voltage domain (0 V for low data bit or ON state and 1.8 V, i.e. V_INT, for high data bit or OFF state) Data line (GPIO1 as module data output) No flow control Fixed baud rate: 921600 b/s Fixed frame format: 8N1 (8 data bits, no parity, 1 stop bit) ☞ For diagnostic purposes, connect a test point to the GPIO1 pin. ☞ The trace diagnostic log is temporarily stopped when the module is in deep-sleep mode.
