1.1 Overview
· SARA-R500S-01B, general purpose LTE Cat M1 / LTE Cat NB2 product designed for multi-regional deployments
The miniature SARA LGA form factor (26.0 x 16.0 mm, 96-pin) allows an easy integration into compact designs and a seamless drop-in migration from other LTRX cellular module families. SARA-R5 series modules are form-factor compatible with the LTRX LISA, LARA and TOBY cellular module families and they are pin-to-pin compatible with the u-blox SARA-R4, SARA-N2, SARA-N3, SARA-N4, SARA-G3, SARA-G4 and SARA-U2 cellular modules families. This facilitates migration from other LTRX LPWA modules as well as from other LTRX GSM/GPRS, CDMA, UMTS/HSPA and higher LTE categories modules, maximizing customer investments, simplifying logistics, and enabling very short time-to-market. SARA-R500S-01B modules provide software-based multi-band configurability enabling international multi-regional coverage in LTE Cat M1 / NB2 radio access technologies, supporting a comprehensive set of 3GPP Rel. 14 features that are relevant for IoT applications. SARA-R500s modules offer data communications up to 1200 kbit/s over an extended operating temperature range of 40 °C to +85 °C, with low power consumption, and with coverage enhancement for deeper range into buildings and basements (and underground with NB2).

LTE-M and NB-IoT 3GPP release 14 features

2 Interfaces
2.1 Power management
2.1.1 Module supply input (VCC)
SARA-R500S-01B modules must be supplied through the VCC pins by a proper external DC power supply providing a nominal voltage within the normal operating range (see Table 11). Voltage must be stable, because during operation the current drawn from VCC may vary significantly, based on the power consumption profile of the LTE Cat M1 and LTE Cat NB2 radio access technologies (described in the SARA-R5 series system integration manual [2]).
The three VCC pins of SARA-R5 series modules are internally connected to both the internal Power Amplifier and the internal Power Management Unit, which integrates voltage regulators generating all the internal supply voltages needed by the module for the designed operations, as the supply voltage for the generic digital interfaces (V_INT), the supply voltage for the SIM interface (VSIM), and the supply voltage for the internal GNSS receiver.
It is important that the system power supply circuit is able to withstand the maximum pulse current during a transmit burst at maximum power level (see Table 13).
2.1.2 Generic digital interfaces supply output (V_INT)
SARA-R5 series modules provide a 1.8 V supply rail output on the V_INT pin, which is internally generated when the module is switched on. The same voltage domain is used internally to supply the generic digital interfaces of the module. The V_INT supply output can be used in place of an external discrete regulator.
It is recommended to provide accessible test point directly connected to the V_INT pin.
2.2 Antenna interface
2.2.1 Cellular antenna RF interface (ANT)
The ANT pin is the cellular RF antenna I/O interface, designed with 50 characteristic impedance.
2.2.2 GNSS antenna RF interface (ANT_GNSS)
The GNSS antenna RF interface is not supported by SARA-R500E, SARA-R500S, SARA-R510S.
The ANT_GNSS pin represents the GNSS RF input of the SARA-R510M8S modules, designed with 50 characteristic impedance and with an internal DC block, suitable for both active and/or passive GNSS antennas due to the built-in SAW filter followed by an LNA in front of the integrated high performing LTRX M8 concurrent positioning engine.
2.2.3 Antenna detection (ANT_DET)
The ANT_DET pin is an Analog to Digital Converter (ADC) input with a current source provided by SARA-R5 series modules to sense the external antenna presence (as an optional feature), evaluating the DC resistance to GND by means of an externally implemented circuit (for more details, see the LTRX SARA-R5 series system integration manual [2] and the SARA-R5 series AT commands manual [1]).

2.3 System functions
2.3.1 Module power-on
When the SARA-R500E, SARA-R500S and SARA-R510M8S modules are not powered, they can be switched on as following:
· Rising edge on the VCC supply input to a valid voltage for modules supply: the modules switch on applying VCC supply starting from a voltage value lower than 2.15 V, providing a fast enough VCC voltage slope, as it must ramp from 2.15 V to 3.0 V within 300 ms, and reach a regular nominal VCC voltage value within the operating range (see Table 11).
When the SARA-R510S modules are not powered, they can be switched on as following:
· Applying a voltage at the VCC module supply input within the operating range (see Table 11), and then forcing a low level at the PWR_ON input pin, which is normally set high by an internal pull-up, for a valid time period (see section 4.2.9, module switch-on).
When the SARA-R5 series modules are in power-off mode (i.e. switched off, but with a valid voltage present at the VCC module supply input within the operating range reported in Table 11), they can be switched on as following:
· Forcing a low level at the PWR_ON input pin, which is normally set high by an internal pull-up, for a valid time period (see section 4.2.9, module switch-on).
When the SARA-R5 series modules are in low power PSM / eDRX6 deep-sleep mode, with a valid voltage present at the VCC module supply input within the operating range reported in Table 11, they can be woken up as following:
· Forcing a low level at the PWR_ON input pin, which is normally set high by an internal pull-up, for a valid time period (see section 4.2.9, module early wake-up from PSM / eDRX deep-sleep).
The PWR_ON line is intended to be driven by open drain, open collector or contact switch.
It is recommended to provide accessible test point directly connected to the PWR_ON input pin.
2.3.2 Module power-off
The proper graceful power-off of the SARA-R5 series modules, with storage of the current parameter settings in the module's non-volatile memory and a clean network detach, can be triggered by:
· AT+CPWROFF command (see the SARA-R5 series AT commands manual [1])
A faster and safe power-off procedure of the modules, with storage of the current parameter settings in the module's non-volatile memory and without a clean network detach, can be triggered by:
· AT+CFUN=10 command (see the SARA-R5 series AT commands manual [1]) · Toggling the GPIO input configured with the faster and safe power-off function (see section 2.7)
An abrupt emergency hardware shutdown of the modules, without saving current parameter settings in the module's non-volatile memory and without clean network detach, can be executed by:
· Forcing a low pulse at the PWR_ON and RESET_N input pins, in the proper sequence described in section 4.2.9 with details in Figure 6

An abrupt under-voltage shutdown occurs on SARA-R5 series modules when the VCC supply is removed. If this occurs, it is not possible to store the current parameter settings in the module's non-volatile memory or to perform the proper network detach.
An over-temperature or an under-temperature shutdown occurs on the SARA-R5 series modules when the temperature measured within the module reaches the dangerous area (see section 4.2.16), if the optional "Smart temperature supervisor" feature is enabled and configured by the dedicated AT command (see the SARA-R5 series AT commands manual [1], +USTS AT command).
2.3.3 Module reset
SARA-R5 series modules can be reset (re-booted), saving current parameter settings in the module's non-volatile memory and performing a proper network detach, by:
· AT+CFUN=16 command (for other options and further details, see the SARA-R5 series AT commands manual [1]). This causes a graceful software reset of the module.
An abrupt software reset of the module is executed by applying a low pulse at the RESET_N input pin, which is normally set high by an internal pull-up, for a valid time period (see section 4.2.10). The current parameter settings are not saved in the module's non-volatile memory and a proper network detach is not performed.
The RESET_N line is intended to be driven by open drain, open collector or contact switch.
It is recommended to provide accessible test point directly connected to the RESET_N input pin.
2.4 SIM
The external SIM interface is not supported by the SARA-R500E modules.
2.4.1 SIM interface
SARA-R5 series modules provide the VSIM, SIM_IO, SIM_CLK, SIM_RST pins as an interface to connect an external SIM card/chip. Both 1.8 V and 3.0 V SIM types are supported. Activation and deactivation with an automatic voltage switch from 1.8 V to 3.0 V is implemented according to the ISO-IEC 7816-3 specifications.
2.4.2 SIM detection
The GPIO5 pin of SARA-R5 series modules is a 1.8 V digital input which can be configured as an external interrupt to detect the SIM card presence (as a feature which can be optionally used), as intended to be properly connected to the mechanical switch of an external SIM card holder.
For more details, see the SARA-R5 series system integration manual [2] and the SARA-R5 series AT commands manual [1].

2.9 Cellular antenna dynamic tuner interface

SARA-R5 series modules include two output pins (named I2S_TXD and I2S_WA) that can optionally be used to control in real time an external antenna tuning IC, as the two pins change their output value dynamically according to the specific current LTE band in use by the module (see Table 5).

I2S_TXD 0 0 1 1

I2S_WA 0 1 0 1

LTE frequency band in use B71 ( < 700 MHz) B12, B13, B28, B85 (700..800 MHz) B5, B8, B18, B19, B20, B26 (800..900 MHz) B1, B2, B3, B4, B25, B66 ( > 1000 MHz)

Table 5: SARA-R5 series modules antenna dynamic tuning truth table

For design guidelines, see the SARA-R5 series system integration manual [2]. For details about how to enable the feature, see the SARA-R5 series AT commands manual [1], +UTEST=4 AT command.

2.10 GNSS peripheral outputs
The GNSS peripheral output pins are not supported by SARA-R500E, SARA-R500S, SARA-R510S
and SARA-R510M8S-00B product versions.
SARA-R510M8S modules provide the following 1.8 V peripheral output pins directly connected to the internal u-blox M8 GNSS chipset (as is illustrated in Figure 4):
· The ANT_ON output pin, over the I2S_RXD pin, can provide optional control for switching off power to an external active GNSS antenna or an external separate LNA. This facility is provided to help minimize power consumption in power save mode operation.
· The GEOFENCE output pin, over the I2S_CLK pin, can provide optional indication of the geofencing status and can be used, for example, to wake up a host on activation.
2.11 Reserved pin (RSVD)
SARA-R5 series modules have a pin reserved for future use, marked as RSVD. This pin is to be left unconnected on the application board.

7.2 Moisture sensitivity levels
SARA-R5 series modules are moisture sensitive devices (MSD) in accordance with the IPC/JEDEC
specification.
The Moisture Sensitivity Level (MSL) relates to the packaging and handling precautions required. SARA-R5 series modules are rated at MSL level 4. For more information regarding moisture sensitivity levels, labeling, storage and drying, see the u-blox package information user guide [3].
For the MSL standard, see IPC/JEDEC J-STD-020 (can be downloaded from www.jedec.org).

7.3 Reflow soldering
Reflow profiles are to be selected according to u-blox recommendations (see the SARA-R5 series system integration manual [2]).
Failure to observe these recommendations can result in severe damage to the device!

7.4 ESD precautions
SARA-R5 series modules contain highly sensitive electronic circuitry and are Electrostatic
Sensitive Devices (ESD). Handling SARA-R5 series modules without proper ESD protection may destroy or damage them permanently.
SARA-R5 series modules are Electrostatic Sensitive Devices (EDS) and require special ESD precautions typically applied to ESD sensitive components.
Table 8 details the maximum ESD ratings of the SARA-R5 series modules.
Proper ESD handling and packaging procedures must be applied throughout the processing, handling and operation of any application that incorporates SARA-R5 series modules.
ESD precautions should be appropriately implemented on the application board where the module is mounted, as described in the SARA-R5 series system integration manual [2].
Failure to observe these precautions can result in severe damage to the device!
