4. POWER SUPPLY

The power supply circuitry and board layout are a very important part in the full product design and they strongly reflect on the product overall performances, hence read carefully the requirements and the guidelines that will follow for a proper design.

Power Supply Requirements

The external power supply must be connected to VBATT and VBATT_PA pads and must fulfil the following requirements:

Power Supply

Nominal Supply Voltage

Operating Voltage Range

Extended Voltange Range

NOTE: The Operating Voltage Range MUST never be exceeded; care must be taken when designing the application’s power supply section to avoid having an excessive voltage drop. If the voltage drop is exceeding the limits it could cause an unintentional power off of ME910C1 module. The Power supply must be higher than 3.20 V to power on the ME910C1 module.

3.8V

Value

3.40 V÷ 4.20 V

3.20 V÷ 4.50 V

Overshoot voltage (regarding MAX Extended Operating Voltage) and drop in voltage (regarding MIN Extended Operating Voltage) MUST never be exceeded; The “Extended Operating Voltage Range” can be used only with completely assumption and application of the HW User guide suggestions.

General Design Rules

The principal guidelines for the Power Supply Design embrace three different design steps:

•

the electrical design of the power supply

•

the thermal design

•

the PCB layout

4.3.1. Electrical Design Guidelines of the power supply

The electrical design of the power supply depends strongly from the power source where this power is drained. We will distinguish them into three categories:

•

+5V input (typically PC internal regulator output)

•

+12V input (typically automotive)

•

Battery

4.3.1.1. +5V Source Power Supply Design Guidelines

•

The desired output for the power supply is 3.8V, hence there's not a big difference

between the input source and the desired output and a linear regulator can be used. A switching power supply will not be suited because of the low drop out requirements.

•

When using a linear regulator, a proper heat sink shall be provided in order to

dissipate the power generated.

•

A Bypass low ESR capacitor of adequate capacity must be provided in order to cut

the current absorption peaks close to the Module, a 100μF capacitor is usually suited.

•

Make sure the low ESR capacitor on the power supply output rated at least 10V.

1VV0301351 Rev.8 Page 29 of 100 2018-09-28

ME910C1 HW User Guide

An example of linear regulator with 5V input is:

Guidelines

4.3.1.2. +12V Source Power Supply Design Guidelines

•

The desired output for the power supply is 3.8V, hence due to the big difference

between the input source and the desired output, a linear regulator is not suited and shall not be used. A switching power supply will be preferable because of its better efficiency.

•

When using a switching regulator, a 500kHz or more switching frequency regulator

is preferable because of its smaller inductor size and its faster transient response. This allows the regulator to respond quickly to the current peaks absorption.

•

In any case the frequency and Switching design selection is related to the

application to be developed due to the fact the switching frequency could also generate EMC interferences.

•

For car PB battery the input voltage can rise up to 15,8V and this should be kept in

mind when choosing components: all components in the power supply must withstand this voltage.

•

A Bypass low ESR capacitor of adequate capacity must be provided in order to cut

the current absorption peaks, a 100μF capacitor is usually suited.

•

Make sure the low ESR capacitor on the power supply output is rated at least 10V.

•

For Car applications a spike protection diode should be inserted close to the power

input, in order to clean the supply from spikes.

1VV0301351 Rev.8 Page 30 of 100 2018-09-28

ME910C1 HW User Guide

An example of switching regulator with 12V input is in the below schematic:

4.3.1.3. Battery Source Power Supply Design Guidelines

The desired nominal output for the power supply is 3.8V and the maximum voltage allowed is 4.2V, hence a single 3.7V Li-Ion cell battery type is suited for supplying the power to the Telit ME910C1 module.

•

A Bypass low ESR capacitor of adequate capacity must be provided in order to cut

the current absorption peaks, a 100μF tantalum capacitor is usually suited.

•

Make sure the low ESR capacitor (usually a tantalum one) is rated at least 10V.

•

A protection diode should be inserted close to the power input, in order to save the

ME910C1 from power polarity inversion. Otherwise the battery connector should be done in a way to avoid polarity inversions when connecting the battery.

•

The battery must be rated to supply peaks of current up to 0.6 A for LTE.

1VV0301351 Rev.8 Page 31 of 100 2018-09-28

ME910C1 HW User Guide

NOTE: DON'T USE any Ni-Cd, Ni-MH, and Pb battery types directly connected with ME910C1. Their use can lead to overvoltage on the ME910C1 and damage it. USE ONLY Li-Ion battery types.

4.3.2. Thermal Design Guidelines

Worst case as reference values for thermal design of ME910C1 are:

•

Average current consumption: 250 mA (LTE CAT M1 and NB1 modes)

•

Average current consumption: 600 mA (GPRS and EDGE modes)

•

Supply voltage: 4.50V

NOTE: Make PCB design in order to have the best connection of GND pads to large surfaces of copper.

NOTE: The ME910C1 includes a function to prevent overheating.

4.3.3. Power Supply PCB layout Guidelines

As seen on the electrical design guidelines the power supply shall have a low ESR capacitor on the output to cut the current peaks on the input to protect the supply from spikes The placement of this component is crucial for the correct working of the circuitry. A misplaced component can be useless or can even decrease the power supply performances.

•

The Bypass low ESR capacitor must be placed close to the Telit ME910C1 power

input pads or in the case the power supply is a switching type it can be placed close to the inductor to cut the ripple provided the PCB trace from the capacitor to the

1VV0301351 Rev.8 Page 32 of 100 2018-09-28

ME910C1 HW User Guide

ME910C1 is wide enough to ensure a dropless connection even during an 0.6 A (LTE) or 2A (GSM) current peak.

•

The protection diode must be placed close to the input connector where the power

source is drained.

•

The PCB traces from the input connector to the power regulator IC must be wide

enough to ensure no voltage drops occur when an 2 A current peak is absorbed (valid only for product supporting GSM mode).

•

The PCB traces to the ME910C1 and the Bypass capacitor must be wide enough to

ensure no significant voltage drops occur. This is for the same reason as previous point. Try to keep this trace as short as possible.

•

To reduce the EMI due to switching, it is important to keep very small the mesh

involved; thus the input capacitor, the output diode (if not embodied in the IC) and the regulator have to form a very small loop.This is done in order to reduce the radiated field (noise) at the switching frequency (100-500 kHz usually).

•

A dedicated ground for the Switching regulator separated by the common ground

plane is suggested.

•

The placement of the power supply on the board should be done in such a way to

guarantee that the high current return paths in the ground plane are not overlapped to any noise sensitive circuitry as the microphone amplifier/buffer or earphone amplifier.

•

The power supply input cables should be kept separate from noise sensitive lines

such as microphone/earphone cables.

•

The insertion of EMI filter on VBATT pins is suggested in those designs where

antenna is placed close to battery or supply lines. A ferrite bead like Murata BLM18EG101TN1 or Taiyo Yuden P/N FBMH1608HM101 can be used for this purpose.

•

VAUX Power Output

A regulated power supply output is provided in order to supply small devices from the module, like: level translators, audio codec, sensors, and others.

Pin R11 can be used also as PWRMON (module powered ON indication) function, because is always active when the module is powered ON and cannot be set to LOW level by any AT command.

Host can only detect deep sleep mode by monitoring of VAUX/PWRMON output pin, since there is no pin dedicated to PSM status indicator,

To turn on the ME910C1 the pad ON_OFF*/WAKE* must be tied low for at least 5 second and then released. The maximum current that can be drained from the ON_OFF*/WAKE* pad is 0,1 mA. ON_OFF*/WAKE* pad can make an asynchronous wakeup of the system from the PSM Mode, before the scheduled event of timer T3412 expired. To make asynchronous exit from PSM mode ON_OFF*/WAKE* pin must be set LOW for at least 5 seconds.

Figure 1 illustrates a simple circuit to power on the module using an inverted buffer output.

Figure 1: Power-on Circuit

NOTE: Don't use any pull up resistor on the ON_OFF*/WAKE* line, it is internally pulled up. Using pull up resistor may bring to latch up problems on the ME910C1 power regulator and improper power on/off of the module. The line ON_OFF*/WAKE* must be connected only in open collector or open drain configuration.

In this document all the lines that are inverted, hence have active low signals are labelled with a name that ends with”#",”*” or with a bar over the name.

To check if the device has powered on, the hardware line PWRMON should be monitored.

WARNING

It is recommended to set the ON_OFF*/WAKE* line LOW to power on the module only after VBATT is higher than 3.20V.

In case this condition it is not satisfied you could use the HW_SHUTDOWN* line to recover it and then restart the power on activity using the ON_OFF*/WAKE* line.

An example of this is described in the following diagram.

After HW_SHUTDOWN* is released you could again use the ON_OFF*/WAKE* line to power on the module.

Power Off

Turning off of the device can be done in two ways:

• via AT command (see ME910C1 Software User Guide, AT#SHDN)

• pin ON_OFF*/WAKE* for at least 3 seconds

Either ways, the device issues a detach request to network informing that the device will not be reachable any more.

NOTE: To check if the device has been powered off or IN PSM mode, the hardware line PWRMON must be monitored. The device is powered off when PWRMON goes low.

In order to avoid a back powering effect it is recommended to avoid having any HIGH logic level signal applied to the digital pins of the ME910C1 when the module is powered off or during an ON-OFF transition.

Wake from deep sleep mode

ME910C1 supports Power Saving Mode (PSM) functionality defined in 3GPP Release 12. When Periodic Update Timer expires, ME910C1 power off until the next scheduled wakeup time. Asynchronous event controlled by host can wake up from deep sleep mode by asserting ON_OFF*/WAKE* pin LOW for at least 5 seconds. Host can detect deep sleep mode by polling VAUX/PWRMON pin if previously configured.

Unconditional Shutdown

HW_SHUTDOWN* is used to unconditionally shutdown the ME910C1. Whenever this signal is pulled low, the ME910C1 is reset. When the device is reset it stops any operation. After the release of the line, the ME910C1 is unconditionally shut down, without doing any detach operation from the network where it is registered. This behaviour is not a proper shut down because any cellular device is requested to issue a detach request on turn off. The HW_SHUTDOWN* is internally controlled on start-up to achieve always a proper power-on reset sequence, so there's no need to control this pin on start-up. To unconditionally shutdown the ME910C1, the pad HW_SHUTDOWN* must be tied low for at least 200 milliseconds and then released. The signal is internally pulled up so the pin can be left floating if not used. If used, then it

must always be connected with an open collector transistor

, to permit to the internal circuitry the power on reset and under voltage lockout functions. During PSM mode, HW_SHUTDOWN toggle has no effect. The use of HW_SHUTDOWN* pin is valid only when ME910C1 has VAUX/PWRMON output HI.

Fast power down

The procedure to power off ME910C1 described in Chapter 5.3 normally takes more than 1 second to detach from network and make ME910C1 internal filesystem properly closed. In case of unwanted supply voltage loss the system can be switched off without any risk of filesystem data corruption by implementing Fast Shut Down feature. Fast Shut Down feature permits to reduce the current consumption and the time-topoweroff to minimum values.

NOTE: Refer to ME910C1 series AT command reference guide (Fast power down - #FASTSHDN) in order to set up detailed AT command.

5.6.1. Fast Shut Down by Hardware

The Fast Power Down can be triggered by configuration of any GPIO. HI level to LOW level transition of GPIO commands fast power down.

The ME910C1 module is provided with by 2 Asynchronous serial ports:

• MODEM SERIAL PORT 1 (Main)

• MODEM SERIAL PORT 2 (Auxiliary)

Several configurations can be designed for the serial port on the OEM hardware, but the most common are:

• RS232 PC com port

• microcontroller UART @ 1.8V (Universal Asynchronous Receive Transmit)

• microcontroller UART @ 5V or other voltages different from 1.8V

Depending from the type of serial port on the OEM hardware a level translator circuit may be needed to make the system work. On the ME910C1 the ports are CMOS 1.8.

5.7.3.1. Modem serial port 1

The serial port 1 on the ME910C1 is a +1.8V UART with all the 7 RS232 signals. It differs from the PC-RS232 in the signal polarity (RS232 is reversed) and levels.

5.7.3.3. RS232 level translation

In order to interface the ME910C1 with a PC com port or a RS232 (EIA/TIA-232) application a level translator is required. This level translator must:

• invert the electrical signal in both directions;

• Change the level from 0/1.8V to +15/-15V.

Actually, the RS232 UART 16450, 16550, 16650 & 16750 chipsets accept signals with lower levels on the RS232 side (EIA/TIA-562), allowing a lower voltage-multiplying ratio on the level translator. Note that the negative signal voltage must be less than 0V and hence some sort of level translation is always required. The simplest way to translate the levels and invert the signal is by using a single chip level translator. There are a multitude of them, differing in the number of drivers and receivers and in the levels (be sure to get a true RS232 level translator not a RS485 or other standards). By convention the driver is the level translator from the 0-1.8V UART to the RS232 level. The receiver is the translator from the RS232 level to 0-1.8V UART. In order to translate the whole set of control lines of the UART you will need:

• 5 drivers

1VV0301351 Rev.8 Page 54 of 100 2018-09-28

ME910C1 HW User Guide

• 3 receivers

An example of RS232 level adaptation circuitry could be done using a MAXIM transceiver (MAX218) In this case the chipset is capable to translate directly from 1.8V to the RS232 levels (Example done on 4 signals only).

The RS232 serial port lines are usually connected to a DB9 connector with the following layout:

General purpose I/O

The ME910C1 module is provided by a set of Configurable Digital Input / Output pins (CMOS 1.8V). Input pads can only be read; they report the digital value (high or low) present on the pad at the read time. Output pads can only be written or queried and set the value of the pad output. An alternate function pad is internally controlled by the ME910C1 firmware and acts depending on the function implemented.

5.8.1. Using a GPIO as INPUT

The GPIO pads, when used as inputs, can be connected to a digital output of another device and report its status, provided this device has interface levels compatible with the

1.8V CMOS levels of the GPIO. Input current (@1.8V) is about 18uA (corrisponding to 100K pulldown value) in all GPIO pin expect GPIO_09 where current is about 100uA. This value is present since ME910 poweron.

Device Status

Led Status

If the digital output of the device to be connected with the GPIO input pad of ME910C1 has interface levels different from the 1.8V CMOS, then it can be buffered with an open collector transistor with a 47K pull up to 1.8V supplied by VAUX/POWERMON R11 pad.

NOTE: In order to avoid a back powering effect it is recommended to avoid having any HIGH logic level signal applied to the digital pins of the ME910C1 when the module is powered off or during an ON/OFF transition.

Refer to ME910C1 series AT command reference guide for GPIO pins configuration.

5.8.2. Using a GPIO as OUTPUT

The GPIO pads, when used as outputs, can drive 1.8V CMOS digital devices or compatible hardware. When set as outputs, the pads have a push-pull output and therefore the pull-up resistor may be omitted.

5.8.3. Indication of network service availability The STAT_LED pin status shows information on the network service availability and Call

status. The function is available as alternate function of GPIO_01 (to be enabled using the AT#GPIO=1,0,2 command).

In the ME910C1 modules, the STAT_LED needs an external transistor to drive an external LED and its voltage level is defined accordingly to the table below:.

6.4.1. PCB Design guidelines

When using the ME910C1, since there's no antenna connector on the module, the antenna must be connected to the ME910C1 antenna pad (K1) by means of a transmission line implemented on the PCB. This transmission line shall fulfil the following requirements:

Item Value

Characteristic

Impedance

50 ohm (+-10%)

Max Attenuation 0,3 dB

Coupling Coupling with other signals shall be avoided

Ground Plane

Cold End (Ground Plane) of antenna shall be equipotential to the ME910C1 ground pins

The transmission line should be designed according to the following guidelines:

• Make sure that the transmission line’s characteristic impedance is 50ohm ;

• Keep line on the PCB as short as possible, since the antenna line loss shall be less than about 0,3 dB;

• Line geometry should have uniform characteristics, constant cross section, avoid meanders and abrupt curves;

• Any kind of suitable geometry / structure (Microstrip, Stripline, Coplanar, Grounded Coplanar Waveguide...) can be used for implementing the printed transmission line afferent the antenna;

• If a Ground plane is required in line geometry, that plane has to be continuous and sufficiently extended, so the geometry can be as similar as possible to the related canonical model;

• Keep, if possible, at least one layer of the PCB used only for the Ground plane; If possible, use this layer as reference Ground plane for the transmission line;

• It is wise to surround (on both sides) the PCB transmission line with Ground, avoid having other signal tracks facing directly the antenna line track.

• Avoid crossing any un-shielded transmission line footprint with other signal tracks on different layers;

• The ground surrounding the antenna line on PCB has to be strictly connected to the main Ground Plane by means of via holes (once per 2mm at least), placed close to the ground edges facing line track;

• Place EM noisy devices as far as possible from ME910C1 antenna line;

• Keep the antenna line far away from the ME910C1 power supply lines;

1VV0301351 Rev.8 Page 70 of 100 2018-09-28

ME910C1 HW User Guide

• If EM noisy devices (such as fast switching ICs, LCD and so on) are present on the PCB hosting the ME910, take care of the shielding of the antenna line by burying it in an inner layer of PCB and surround it with Ground planes, or shield it with a metal frame cover.

• If EM noisy devices are not present around the line, the use of geometries like Microstrip or Grounded Coplanar Waveguide has to be preferred, since they typically ensure less attenuation if compared to a Stripline having same length;

6.4.2. PCB Guidelines in case of FCC Certification

In the case FCC certification is required for an application using ME910C1, according to FCC KDB 996369 for modular approval requirements, the transmission line has to be similar to that implemented on ME910C1 interface board and described in the following chapter.

6.4.2.1. Transmission line design

During the design of the ME910C1 interface board, the placement of components has been chosen properly, in order to keep the line length as short as possible, thus leading to lowest power losses possible. A Grounded Coplanar Waveguide (G-CPW) line has been chosen, since this kind of transmission line ensures good impedance control and can be implemented in an outer PCB layer as needed in this case. A SMA female connector has been used to feed the line. The interface board is realized on a FR4, 4-layers PCB. Substrate material is characterized by relative permittivity εr = 4.6 ± 0.4 @ 1 GHz, TanD= 0.019 ÷ 0.026 @ 1 GHz. A characteristic impedance of nearly 50 Ω is achieved using trace width = 1.1 mm, clearance from coplanar ground plane = 0.3 mm each side. The line uses reference ground plane on layer 3, while copper is removed from layer 2 underneath the line. Height of trace above ground plane is 1.335 mm. Calculated characteristic impedance is 51.6 Ω, estimated line loss is less than 0.1 dB. The line geometry is shown below:

ME910C1 HW User Guide

6.4.2.2. Transmission Line Measurements

An HP8753E VNA (Full-2-port calibration) has been used in this measurement session. A calibrated coaxial cable has been soldered at the pad corresponding to RF output; a SMA connector has been soldered to the board in order to characterize the losses of the transmission line including the connector itself. During Return Loss / impedance measurements, the transmission line has been terminated to 50 Ω load. Return Loss plot of line under test is shown below:

6.4.2.3. Antenna Installation Guidelines

•

Install the antenna in a place covered by the LTE signal with CAT-M1 support.

•

Antenna must not be installed inside metal cases

•

Antenna must not be installed according Antenna manufacturer instructions

•

Antenna integration should optimize the Radiation Efficiency. Efficiency values >

50% are recommended on all frequency bands

•

Antenna integration should not perturb the radiation pattern described in Antenna

manufacturer documentation.

•

It is preferable to get an omnidirectional radiation pattern to

•

Antenna Gain must not exceed values indicated in regulatory requirements, where

applicable, in order to meet related EIRP limitations. Typical antenna Gain in most M2M applications does not exceed 2dBi

•

If the device antenna is located farther than 20cm from the human body and there

are no co-located transmitter then the Telit FCC/IC approvals can be re-used by the end product

•

If the device antenna is located closer than 20cm from the human body or there are

co-located transmitter then the additional FCC/IC testing may be required for the end product (Telit FCC/IC approvals cannot be reused)

RF Front End Design

The ME910C1 Module contains a pre-select SAW filter but doesn’t contain the LNA needed to reach the maximum sensitivity. Active antenna (antenna with a built-in low noise amplifier) must be used and must be supplied with proper bias-tee circuit.

8.2.1. Guidelines of PCB line for GNSS Antenna

•

Ensure that the antenna line impedance is 50ohm.

•

Keep the antenna line on the PCB as short as possible to reduce the loss.

•

Antenna line must have uniform characteristics, constant cross section, avoid

meanders and abrupt curves.

•

Keep one layer of the PCB used only for the Ground plane, if possible.

•

Surround (on both the sides, over and under) the antenna line on PCB with Ground,

avoid having other signal tracks facing directly the antenna line of track.

•

The ground around the antenna line on PCB has to be strictly connected to the

Ground Plane by placing vias once per 2mm at least.

•

Place EM noisy devices as far as possible from antenna line.

•

Keep the antenna line far away from power supply lines.

•

Keep the antenna line far away from GSM RF lines.

•

If you have EM noisy devices around the PCB hosting the module, such as fast

switching ICs, take care of the shielding of the antenna line by burying it inside the layers of PCB and surround it with Ground planes, or shield it with a metal frame cover.

•

If you do not have EM noisy devices around the PCB hosting the module, use a

strip-line on the superficial copper layer for the antenna line. The line attenuation will be lower than a buried one.

GNSS Antenna Requirements

GNSS active antenna must be used or integrated in the application.

8.3.2. GNSS Antenna – Installation Guidelines

• The antenna must be installed according to the antenna manufacturer’s instructions to obtain the maximum performance of GNSS receiver.

• The antenna location must be evaluated carefully if operating in conjunction with any other antenna or transmitter.

• The antenna must not be installed inside metal cases or near any obstacle that may degrade features like antenna lobes and gain.

8.3.3. Powering the External LNA (active antenna)

The LNA of active antenna needs a source of power because 1.8V or 3V DC voltage needed by active antenna is not supplied by the ME910C1 module, but can be easily included by the host design.

The electrical characteristics of the GPS_LNA_EN signal are:

1.6 1.9 0V 0.3

Example of external antenna bias circuitry:

1VV0301351 Rev.8 Page 78 of 100 2018-09-28

ME910C1 HW User Guide

Be aware of max bias current in case of unwanted short on antenna cable, decoupling inductor may be demaged.

In case of LNA with 1.8V supply, VAUX/POWERMON pin can be used to supply active GNSS antenna

10. APPLICATION PCB DESIGN

The ME910C1 modules have been designed in order to be compliant with a standard leadfree SMT process

Footprint

TOP VIEW

In order to easily rework the ME910C1 is suggested to consider on the application a 1.5 mm placement inhibit area around the module. It is also suggested, as common rule for an SMT component, to avoid having a mechanical part of the application in direct contact with the module.

NOTE: In the customer application, the region under WIRING INHIBIT (see figure above) must be clear from signal or ground paths.

PCB pad dimensions

The recommendation for the PCB pads dimensions are described in the following image (dimensions in mm)

Solder resist openings

It is not recommended to place via or micro-via not covered by solder resist in an area of 0,3 mm around the pads unless it carries the same signal of the pad itself

Inhibit area for micro-via

1VV0301351 Rev.8 Page 83 of 100 2018-09-28

ME910C1 HW User Guide

Holes in pad are allowed only for blind holes and not for through holes.

Recommendations for PCB pad surfaces:

Finish Layer Thickness (um) Properties

Electro-less Ni /

Immersion Au

3 –7 / 0.05 – 0.15 good solder ability protection,

high shear force values

The PCB must be able to resist the higher temperatures which are occurring at the leadfree process. This issue should be discussed with the PCB-supplier. Generally, the wettability of tin-lead solder paste on the described surface plating is better compared to lead-free solder paste.

It is not necessary to panel the application’s PCB, however in that case it is suggested to use milled contours and predrilled board breakouts; scoring or v-cut solutions are not recommended

Stencil

Stencil’s apertures layout can be the same of the recommended footprint (1:1), we suggest a thickness of stencil foil ≥ 120 µm.

Solder paste

Item Lead Free

Solder Paste Sn/Ag/Cu

We recommend using only “no clean” solder paste in order to avoid the cleaning of the modules after assembly
