TOBY-R2 series - Data Sheet
1 Functional description
1.1 Overview
The TOBY-R2 series comprises LTE Cat 1 / 3G / 2G multi-mode modules in the small TOBY LGA form-factor
(35.6 x 24.8 mm) that are easy to integrate in compact designs.
TOBY-R2 series modules support up to five LTE bands, up to four 3G UMTS/HSPA bands and up to four 2G
GSM/(E)GPRS bands for voice and/or data transmission.
TOBY-R2 series modules are form-factor compatible with u-blox SARA, LISA and LARA cellular module families
and are pin-to-pin compatible with u-blox TOBY-L cellular module families: this facilitates easy migration from
the u-blox GSM/GPRS, CDMA, UMTS/HSPA, and LTE high data rate modules, maximizes the investments of
customers, simplifies logistics, and enables very short time-to-market.
The modules are ideal for applications that are transitioning to LTE from 2G and 3G, due to the long term
availability and scalability of LTE networks.
With a range of interface options and an integrated IP stack, the modules are designed to support a wide range
of data-centric applications. The unique combination of performance and flexibility make these modules ideally
suited for medium speed M2M applications, such as smart energy gateways, remote access video cameras,
digital signage, telehealth and telematics.
TOBY-R2 series modules support Voice over LTE (VoLTE) and voice service over 3G (CSFB) for applications that
require voice, such as security and surveillance systems.

Feature
Description
LTE Rx Diversity
Improved cellular link quality and reliability on all operating bands, by means of 2 receiving antenna inputs.
GNSS via modem7
Full access to u-blox positioning chips and modules is available through a dedicated DDC (I 2C) interface. This means
that from any host processor a single serial port can control the cellular module and the positioning chip or module.
For more details see the GNSS Implementation Application Note [5].
Embedded AssistNow

device based on the CellLocate® database:

Normal scan: only the parameters of the visible home network cells are sent

Deep scan: the parameters of all surrounding cells of all mobile operators are sent
CellLocate® is available via a set of AT commands for CellLocate ® service configuration and position request.
Hybrid Positioning7
The current module position is provided by a u-blox positioning chip or module or the estimated position from
CellLocate® depending on which method provides the best and fastest solution according to the user configuration.
Hybrid positioning is available via a set of AT commands that allow the configuration and the position request.
Wi-Fi via modem7
Full access to Wi-Fi modules is available through a dedicated SDIO interface. This means that from any host
processor a single serial port can control the cellular module and the short range communication module.
Smart Temperature
Supervisor
Constant monitoring of the module board temperature:

Warning notification when the temperature approaches an upper or lower predefined threshold

Shutdown notified and forced when the temperature value is outside the specified range (shutdown
suspended in case of an emergency call in progress)
The Smart Temperature Supervisor feature can be enabled and configured through the +USTS AT command.
The sensor measures board temperature, which can differ from ambient temperature.
Power saving
The power saving configuration is by default disabled, but it can be enabled and configured using the +UPSV AT
command. When the power saving is enabled, the module automatically enters the low power idle-mode whenever
possible, reducing current consumption.
During idle-mode, the module processor core runs with the RTC 32 kHz reference clock, which is generated by the
internal 32 kHz oscillator.
Fast Dormancy
The Fast Dormancy feature, defined in 3GPP Rel.8, allows reduction of current consumption and network utilization
during periods of data inactivity. It can be activated and configured by +UFDAC and +UDCONF=61 AT commands.
LTE cDRX
Both the Long DRX Cycle and the Short DRX cycle are supported for LTE Connected Discontinuous Reception,
allowing reduction of current consumption and LTE network utilization during periods of data inactivity
Power Saving Mode
(PSM) as specified in
3GPP Release 127
The Power Saving Mode (PSM) feature, defined in 3GPP Rel.12, allows further reduction of the module current
consumption by decreasing the signaling load between the module and the network on non-access stratum level
during periods of data inactivity. It can be activated and configured by dedicated AT commands.

2 Interfaces
2.1 Power management
2.1.1 Module supply input (VCC)
TOBY-R2 series modules must be supplied through the three VCC pins by a DC power supply. Voltage must be
stable, because 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 TOBY-R2 series System Integration
Manual [2]). It is important that the system power supply circuit is able to support peak power.
TOBY-R200 modules provide separate supply inputs over the three VCC pins:

VCC pins #71 and #72 represent the supply input for the internal RF power amplifier, demanding most of
the total current drawn by the module when RF transmission is enabled during a voice/data call

VCC pin #70 represents the supply input for the internal baseband Power Management Unit and the internal
transceiver, demanding minor part of the total current drawn by the module when RF transmission is
enabled during a voice/data call
2.1.2 RTC supply input / output (V_BCKP)
When VCC voltage is within the valid operating range, the internal Power Management Unit (PMU) supplies the
Real Time Clock (RTC) and the same supply voltage is available on the 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 Generic digital interfaces supply output (V_INT)
TOBY-R2 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 modules. The V_INT supply output can be used in place of an external discrete regulator.
2.2 Antenna interfaces
2.2.1 Antenna RF interfaces
The modules have two RF pins with a characteristic impedance of 50 . The primary antenna pin (ANT1)
supports both Tx and Rx, providing the main antenna interface, while the secondary antenna pin (ANT2)
supports Rx only for the LTE Rx diversity configuration.
2.2.2 Antenna detection
The ANT_DET pin is an Analog to Digital Converter (ADC) input with a current source provided by TOBY-R2
modules to sense the antenna presence (as an optional feature). It evaluates the resistance from ANT1 and
ANT2 pins to GND by means of an external antenna detection circuit implemented on the application board.
(For more details, see TOBY-R2 series System Integration Manual [2] and u-blox AT Commands Manual [1].)

2.3 System functions
2.3.1 Module power-on
TOBY-R2 series can be switched on in one of the following ways:

Rising edge on the VCC pins to a valid voltage for module supply, i.e. applying module supply: the modules
switch on if the VCC supply is applied, starting from a voltage value of less than 2.1 V, with a rise time from
2.3 V to 2.8 V of less than 4 ms, reaching a proper nominal voltage value within VCC operating range.
Alternately, in case for example the fast rise time on VCC rising edge cannot be guaranteed by the application,
TOBY-R2 series modules can be switched on from not-powered mode as following:

RESET_N input pin is held low by the external application during the VCC rising edge, so that the modules
will switch on when the external application releases the RESET_N input pin from the low logic level after
the VCC supply voltage stabilizes at its proper nominal value within the operating range

PWR_ON input pin is held low by the external application during the VCC rising edge, so that the modules
will switch on when the external application releases the PWR_ON input pin from the low logic level after
the VCC supply voltage stabilizes at its proper nominal value within the operating range
When the TOBY-R2 series modules are in the power-off mode (i.e. properly switched off as described in section
2.3.2, with valid VCC module supply applied), they can be switched on as follows:

Low pulse on the PWR_ON pin, which is normally set high by an internal pull-up, for a valid time period (see
section 4.2.8). The PWR_ON line should be driven by open drain, open collector or contact switch.

Rising edge on the RESET_N pin, i.e. releasing the pin from the low level, normally set high by an internal
pull-up. The RESET_N line should be driven by open drain, open collector or contact switch.

RTC alarm, i.e. pre-programmed scheduled time by AT+CALA command.
2.3.2 Module power-off
TOBY-R2 series can be properly switched off, saving current parameter settings in the module’s non-volatile
memory and performing a proper network detach, by:

AT+CPWROFF command (see the u-blox AT Commands Manual [1]).

Low pulse on the PWR_ON pin, which is normally set high by an internal pull-up, for a valid time period (see
section 4.2.8). The PWR_ON line should be driven by open drain, open collector or contact switch.
An abrupt under-voltage shutdown occurs on TOBY-R2 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 and to
perform the proper network detach.
An abrupt shutdown occurs on TOBY-R2 series modules when a low level is applied on the RESET_N pin, which
is normally set high by an internal pull-up. If this occurs, it is not possible to store the current parameter settings
in the module’s non-volatile memory and to perform the proper network detach.
An over-temperature or an under-temperature shutdown occurs on TOBY-R2 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 TOBY-R2 series
System Integration Manual [2] and the u-blox AT Commands Manual [1], +USTS AT command.

2.3.3 Module reset
TOBY-R2 series modules can be reset (rebooted) by:

AT+CFUN command (see the u-blox AT Commands Manual [1]). This causes an “internal” or “software”
reset of the module. The current parameter settings are saved in the module’s non-volatile memory and a
proper network detach is performed.
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 the section 4.2.9). This causes an “external”
or “hardware” reset of the entire module, including the integrated power management unit, except for the RTC
internal block: the V_INT generic digital interfaces supply is switched off and all the digital pins are tri-stated,
but the V_BCKP supply and the RTC block are enabled. 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 should be
driven by open drain, open collector or contact switch.
2.3.4 Module / host configuration selection
Selection of module / host configuration over HOST_SELECT0 and HOST_SELECT1 pins is not supported.
TOBY-R2 series modules include two pins (HOST_SELECT0, HOST_SELECT1) for the selection of the module /
host application processor configuration.
2.4 SIM
2.4.1 SIM interface
A SIM card interface is provided on the VSIM, SIM_IO, SIM_CLK, SIM_RST pins: 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 (1.8 V and 3 V ME). Activation and deactivation with automatic
voltage switch from 1.8 V to 3 V is 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/chip.
2.4.2 SIM detection
TOBY-R2 series modules provide the SIM detection function over the GPIO5 pin to sense the SIM card physical
presence (as an optional feature) when the pin of the module is properly connected to the mechanical switch of
the SIM car holder (for more details see the TOBY-R2 series System Integration Manual [2]).


One-shot autobauding is supported and it is by default enabled: automatic baud rate detection is performed
only once, at module start up. After the detection, the module works at the fixed baud rate (the detected
one) and the baud rate can only be changed via AT command (see u-blox AT Commands Manual [1], +IPR).

The following frame format are supported: 8N2, 8N1 (default format when automatic frame recognition is
disabled), 8E1, 8O1, 7E1 and 7O1

One-shot automatic frame recognition is supported and it is by default enabled in conjunction with
automatic baud rate detection (autobauding): the detection is performed only once, at module start up.
After the detection, the module works at the detected frame format and it can only be changed via AT
command (see u-blox AT Commands Manual [1], +ICF).
UART serial interface can be conveniently configured through AT commands: see the u-blox AT Commands
Manual [1] (+IPR, +ICF, +IFC, &K, \Q, +UPSV AT commands) and TOBY-R2 series System Integration Manual [2].

2.5.3 DDC (I2C) interface
Communication with u-blox GNSS receivers over DDC (I C) is not supported by “02” product versions.
TOBY-R2 series modules include an I C-bus compatible DDC interface (SDA, SCL) available to communicate with
a u-blox GNSS receiver and with external I C devices as an audio codec: the TOBY-R2 module acts as an I C
master which can communicate with I C slaves in accordance with the I C bus specifications [16].
For more details regarding the DDC (I C) interface usage and the integration with a u-blox GNSS receiver see the
TOBY-R2 series System Integration Manual [2], the GNSS Implementation Application Note [5], and the I C and
GNSS AT commands description in the u-blox AT Commands Manual [1].
2.5.4 SDIO interface
The SDIO interface is not supported by “02” modules product versions.
TOBY-R2 series modules include a 4-bit Secure Digital Input Output interface (SDIO_D0, SDIO_D1, SDIO_D2,
SDIO_D3, SDIO_CLK, SDIO_CMD) designed to communicate with external compatible u-blox short range radio
communication Wi-Fi modules.
2.6 Audio
TOBY-R2 series modules support Voice over LTE (VoLTE) as well as Circuit-Switched Fall-Back (CSFB) from LTE to
3G or 2G radio bearer for providing audio services.
TOBY-R2 series modules include a 4-wire I S digital audio interface (I2S_TXD, I2S_RXD, I2S_CLK, I2S_WA) that
can be configured by AT command in PCM mode (short synchronization signal) or in normal I S mode (long
synchronization signal) to transfer digital audio data to/from an external device as an audio codec.
For more details regarding internal audio processing system capabilities, I S digital audio interface possible
configurations, usage and guideline for the integration with an external digital audio device as an audio codec
see TOBY-R2 series System Integration Manual [2] and the audio sections in u-blox AT Commands Manual [1].
2.7 Clock output
TOBY-R2 series modules provide a master digital clock output function on the GPIO6 pin, which can be
configured to provide a 13 MHz or 26 MHz square wave. This is mainly designed to feed the master clock input
of an external audio codec, as the clock output can be configured in “Audio dependent” mode (generating the
square wave only when the audio path is active), or in “Continuous” mode.
For more details see the u-blox AT Commands Manual [1], +UMCLK AT command.

7.2 Moisture Sensitivity Levels
TOBY-R2 series modules are Moisture Sensitive Devices (MSD) in accordance to the IPC/JEDEC
specification.
The Moisture Sensitivity Level (MSL) relates to the packaging and handling precautions required. TOBY-R2 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 Guide [7].
For 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 TOBY-R2 series System Integration
Manual [2]).
Failure to observe these recommendations can result in severe damage to the device!
7.4 ESD precautions
TOBY-R2 series modules contain highly sensitive electronic circuitry and are Electrostatic
Sensitive Devices (ESD). Handling TOBY-R2 series modules without proper ESD protection may
destroy or damage them permanently.
TOBY-R2 series modules are Electrostatic Sensitive Devices (ESD) and require special ESD precautions typically
applied to ESD sensitive components.
Table 7 reports the maximum ESD ratings of the TOBY-R2 series modules.
Proper ESD handling and packaging procedures must be applied throughout the processing, handling and
operation of any application that incorporates TOBY-R2 series module.
ESD precautions should be implemented on the application board where the module is mounted, as described in
the TOBY-R2 series System Integration Manual [2].
Failure to observe these recommendations can result in severe damage to the device!
