1 Introduction
This document defines the MC60 module and describes its hardware interface which is connected with
the customer application as well as its air interface.
The document can help you quickly understand module interface specifications, as well as the electrical
and mechanical details. Associated with application note and user guide, you can use MC60 module to
design and set up mobile applications easily.
1.1. Safety Information
The following safety precautions must be observed during all phases of the operation, such as usage,
service or repair of any cellular terminal or mobile incorporating MC60 module. Manufacturers of the
cellular terminal should send the following safety information to users and operating personnel, and
incorporate these guidelines into all manuals supplied with the product. If not so, Quectel assumes no
liability for the customer’s failure to comply with these precautions.
Full attention must be given to driving at all times in order to reduce the risk of an
accident. Using a mobile while driving (even with a handsfree kit) causes
distraction and can lead to an accident. You must comply with laws and regulations
restricting the use of wireless devices while driving.
Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it is
switched off. The operation of wireless appliances in an aircraft is forbidden, so as
to prevent interference with communication systems. Consult the airline staff about
the use of wireless devices on boarding the aircraft, if your device offers a Airplane
Mode which must be enabled prior to boarding an aircraft.
Switch off your wireless device when in hospitals, clinics or other health care
facilities. These requests are desinged to prevent possible interference with
sentitive medical equipment.

GSM/GPRS/GNSS Module Series
MC60 Hardware Design
Cellular terminals or mobiles operating over radio frequency signal and cellular
network cannot be guaranteed to connect in all conditions, for example no mobile
fee or with an invalid SIM card. While you are in this condition and need emergent
help, please remember using emergency call. In order to make or receive a call,
the cellular terminal or mobile must be switched on and in a service area with
adequate cellular signal strength.
Your cellular terminal or mobile contains a transmitter and receiver. When it is ON ,
it receives and transmits radio frequency energy. RF interference can occur if it is
used close to TV set, radio, computer or other electric equipment.
In locations with potencially explosive atmospheres, obey all posted signs to turn
off wireless devices such as your phone or other cellular terminals. Areas with
potencially explosive atmospheres include fuelling areas, below decks on boats,
fuel or chemical transfer or storage facilities, areas where the air contains
chemicals or particles such as grain, dust or metal powders, etc.

2 Product Concept
2.1. General Description
MC60 is a multi-purpose module which integrates a high performance GNSS engine and a dual-band
GSM/GPRS engine. It can work as all-in-one solution or stand-alone solution according to customers'
application demands.
The dual-band GSM/GPRS engine can work at frequencies of EGSM900MHz and DCS1800MHz. MC60
features GPRS multi-slot class 12 and supports the GPRS coding schemes CS-1, CS-2, CS-3 and CS-4.
For more details about GPRS multi-slot classes and coding schemes, please refer to the Appendix B &
C.
The GNSS engine is a single receiver integrating GLONASS and GPS systems. It supports multiple
positioning and navigation systems including autonomous GPS, GLONASS, SBAS (including WAAS,
EGNOS, MSAS and GAGAN), and QZSS. It is able to achieve the industry’s highest level of sensitivity,
accuracy and TTFF with the lowest power consumption. The embedded flash memory provides capacity
for storing user-specific configurations and allows for future updates.
MC60 is an SMD type module with 54 LCC pads and 14 LGA pads which can be easily embedded into
applications. With a compact profile of 18.7mm × 16.0mm × 2.1mm, the module can meet almost all the
requirements for M2M applications, including vehicle and personal tracking, wearable devices, security
systems, wireless POS, industrial PDA, smart metering, remote maintenance & control, etc.
Designed with power saving technique, the current consumption of MC60 is as low as 1.2mA in SLEEP
mode when DRX is 5 and the GNSS part is powered off. The GNSS engine also has many advanced
power saving modes including standby and backup modes which can fit the requirement of low-power
consumption in different scenes.
GSM part of MC60 is integrated with Internet service protocols such as TCP/UDP, PPP, HTTP and FTP.
Extended AT commands have been developed for you to use these Internet service protocols easily.
EASY technology as a key feature of GNSS part of MC60 module is one kind of AGPS. Capable of
collecting and processing all internal aiding information like GNSS time, ephemeris, last position, etc., the
GNSS part will have a fast TTFF in either Hot or Warm start.
The module fully complies with the RoHS directive of the European Union.

1. 1) Within operation temperature range, the module is 3GPP compliant.
2. 2) Within extended temperature range, the module remains the ability to establish and maintain a
voice, SMS, data transmission, emergency call, etc. There is no unrecoverable malfunction. There
are also no effects on radio spectrum and no harm to radio network. Only one or more parameters like
P
might reduce in their value and exceed the specified tolerances. When the temperature returns to
out
the normal operating temperature levels, the module will meet 3GPP compliant again.

3.2. Application Modes Introduction
MC60 module integrates both GSM and GNSS engines which can work as a whole (all-in-one solution)
unit or work independently (stand-alone solution) according to customer demands.
MC60_Hardware_Design Confidential / Released 25 / 99
GSM/GPRS/GNSS Module Series
MC60 Hardware Design
In all-in-one solution, the MC60 works as a whole unit. The GNSS Part can be regarded as a peripheral of
the GSM Part. This allows for convenient communication between GSM and GNSS Parts, such as AT
command sending for GNSS control, GNSS part firmware upgrading, and EPO data download.
In stand-alone solution, GSM and GNSS Parts work independently, and thus have to be controlled
separately.
All-in-one solution and stand-alone solution schematic diagrams are shown below.

3.3. Power Supply
3.3.1. Power Features
The power supply of the GSM part is one of the key issues in MC60 module design. Due to the 577us
radio burst in GSM part every 4.615ms, the power supply must be able to deliver high current peaks in a
burst period. During these peaks, drops on the supply voltage must not exceed the minimum working
voltage of the module.
For MC60 module, the maximum current consumption could reach 1.6A during a burst transmission. It will
cause a large voltage drop on the VBAT. In order to ensure stable operation of the module, it is
recommended that the maximum voltage drop during the burst transmission does not exceed 400mV.

GSM/GPRS/GNSS Module Series
MC60 Hardware Design
Figure 5: Voltage Ripple during Transmitting
3.3.2. Decrease Supply Voltage Drop
3.3.2.1. Decrease Supply Voltage Drop for GSM Part
Power supply range of the GSM part is from 3.3V to 4.6V. Make sure that the input voltage will never drop
below 3.3V even in a burst transmission. If the power voltage drops below 3.3V, the module will be turned
off automatically. For better power performance, it is recommended to place a 100uF tantalum capacitor
with low ESR (ESR=0.7Ω) and ceramic capacitors 100nF, 33pF and 10pF near the VBAT pin. A reference
circuit is illustrated in the following figure.
The VBAT trace should be wide enough to ensure that there is not too much voltage drop during burst
transmission. The width of trace should be no less than 2mm; and in principle, the longer the VBAT trace,
the wider it will be.
Figure 6: Reference Circuit for the VBAT Input
MC60_Hardware_Design Confidential / Released 28 / 99

MC60 Hardware Design
3.3.2.2. Decrease Supply Voltage Drop for GNSS Part
The same as VBAT, power supply range of GNSS part is from 2.8 to 4.3V. Typical GNSS_VCC peak
current is 40mA during GNSS acquisition after power up. So it is important to supply sufficient current and
make the power clean and stable. The decouple combination of 10uF and 100nF capacitor is
recommended nearby GNSS_VCC pin. A reference circuit is illustrated in the following figure.
Figure 7: Reference Circuit for the GNSS_VCC Input
3.3.3. Reference Design for Power Supply
3.3.3.1. Reference Design for Power Supply of GSM Part
In all-in-one solution, the GSM part controls the power supply of the GNSS part. Therefore, the GSM part
share the same power circuit design in both all-in-one and stand-alone solutions.
The power supply of GSM part is capable of providing sufficient current up to 2A at least. If the voltage
drop between the input and output is not too high, it is suggested to use a LDO as the module’s power
supply. If there is a big voltage difference between the input source and the desired output (VBAT), a
switcher power converter is recommended to be used as the power supply.
The following figure shows a reference design for +5V input power source for GSM part. The designed
output for the power supply is 4.0V and the maximum load current is 3A. In addition, in order to get a
stable output voltage, a zener diode is placed close to the pins of VBAT. As to the zener diode, it is
suggested to use a zener diode whose reverse zener voltage is 5.1V and dissipation power is more than 1
Watt.
