Introduction
2 Introduction
2.1 Product concept
G600 GPRS Module supports four GSM bands. 900/1800 MHz or 850/1900 MHz, and with
GPRS multi-slot class 10, G600 can operate on any GSM/GPRS network to provide voice and data
communications.
The G600 is similar to a condensed cellular phone core, which can be integrated into any
system or product that needs to transfer voice or data information over a cellular network. Thus, it
significantly enhances the system's capabilities, transforming it from a standalone, isolated product
to a powerful high-performance system with global communications capabilities.
The G600 is designed as a complete GSM/GPRS communications solution with all the
controls, interfaces and features to support a broad range of applications:
Low cost
Wider voltage operate range
A variety set of indicators and control signals
More lower power consumption
A variety of serial communications solutions.
All these features and interfaces are easily controlled and configured using a versatile AT
command interface that provides full control over the G600 operation.
The G600 control and indication interface extends its capabilities beyond GSM
communications. This includes an A/D and GPIO interface, and a regulated output voltage for
supplying external circuits. With these interfaces, the G600 can operate and control external
applications and receive feedback from external environment and circuits.
The G600 interface design, using a single 50 pin board-to-board connector, through which all
application interfaces are managed, facilitates fast and easy integration. It significantly shortens the
development process, and minimizes the product's time to market.
The G600 is extremely compact in size with a slim mechanical design, which makes it space
saving on the application board and easily fitted into any board design.
The advanced power supply management significantly reduces power consumption to a
necessary minimum and prolongs battery life.

3.3.1 Power Supply Design
Special care must be taken when designing the power supply of the G600. The single external
DC power source indirectly supplies all the digital and analog interfaces, but also directly supplies
the RF power amplifier (PA). Therefore, any degradation in the power supply performance, due to
losses, noises or transients, will directly affect the G600 performance.
The burst-mode operation of the GSM transmission and reception draws instantaneous
current surges from the power supply, which causes temporary voltage drops of the power supply
G600 GPRS Module Hardware User Manual Page 13 of 41
HardwareInterfaceDescription
level. The transmission bursts consume the most instantaneous current, and therefore cause the
largest voltage drop. If the voltage drops are not minimized, the frequent voltage fluctuations may
degrade the G600 performance.
It is recommended that the voltage drops during a transmit burst will not exceed 300mV,
measured on the G600 interface connector. In any case, the G600 supply input must not drop
below the minimum operating level during a transmit burst. Dropping below the minimum operating
level may result in a low voltage detection, which will initiate an automatic power-off.
To minimize the losses and transients on the power supply lines, it is recommended to follow
these guidelines:
BATT 300mV max
3.3V min
TX_EN
Use a 1000 uF, or greater, low ESR capacitor on the G600 supply inputs. The capacitor
should be located as near to the G600 interface connector as possible.
Use low impedance power source, cabling and board routing.
Use cabling and routing as short as possible.
Filter the G600 supply lines using filtering capacitors, as described in the table.

3.4 Power On/Off Operation
The G600 power on and off is the two primary phases, which are related at the interface
connector by the hardware signals POWER_ON, VDD.
The POWER_ON signal is main controller.
The VDD signal indicates whether G600 is powered on or off. When this signal is disable (0V),
G600 is powered-off. When it is output (2.85V), G600 is powered-on.
Important: When the VBAT power supplied, the G600 module will be turn on automatically.
Important: The VDD would be flowed backwards by other IOs which be connected extend
voltage. So DSR/CTS/LPG can be indicated the powered on process replaced.
Important: The TXD should be pulled up continuously between the G600 turn on process.

3.4.1 Turning the G600 On
When the G600 is powered off, the PMU operates at low power mode, with only the RTC timer
active. G600 will power on again when the POWER_ON signal is falling edge. Asserting the
POWER_ON signal low for a minimum of 800 milliseconds will turn G600 on.
The figure illustrates the G600 power on is succeeded.

3.4.2 Turning the G600 Off
There are several ways to turn the G600 off:
Asserting the POWER_ON signal low for a minimum of 3 seconds.
Undervoltage automatic shutdown.
Overvoltage automatic shutdown.
AT command.
3.4.2.1 Turning the G600 Off Using POWER_ON
The POWER_ON signal is set high using an internal pull up resistor when power is applied to
G600. When the POWER_ON signal is falling edge and keeping low for a minimum of 3 seconds
will turn G600 off. This will initiate a normal power-off process, which includes disabling of all
applications interfaces (UART, SIM card, audio, etc.) and logout the network connection.

3.4.2.2 Undervoltage automatic shutdown
A low power shut down occurs when G600 senses the external power supply is below the
minimal operating limit (VBAT≤3.2V). The module will respond by powering down automatically
without notice.
This form of power-down is not recommended for regular use since the unexpected power loss
may result in loss of data.
3.4.3 Turning the G600 Off Using AT Command
+MRST
The AT+MRST command initiates a G600 power off operation, which powers off the G600
without logout networks.
+CFUN
The AT+CFUN=0 command initiates a G600 power off operation, which powers off the G600
with logout networks.
3.5 Sleep Mode
The G600 incorporates an optional low power mode, called Sleep Mode, in which it operates
in minimum functionality, and therefore draws significantly less current.
During Sleep Mode the G600 network connection is not lost. G600 will be waked up cycled
and monitored the GSM network constantly for any incoming calls or data. During Sleep mode, all
of the G600 interface signals are inactive and are kept in their previous state, prior to activating low
G600 GPRS Module Hardware User Manual Page 18 of 41
HardwareInterfaceDescription
power mode. To save power, all the G600 internal clocks and circuits are shut down, and therefore
serial communications is limited.
The CTS_N signal is alternately enabled (LOW level) and disabled (HIGH level) synchronously
with Sleep Mode and Idle mode. At the same time this indicates the G600 serial interfaces are
active.
Important: G600 will not enter Sleep mode in any case when there is data present on the
serial interface or incoming from the GSM network or an internal system task is running. Only when
processing of any external or internal system task has completed, G600 will enter Sleep mode
according to the ATS24 command settings.
Important: All of the description about CTS_N, it must be set the UART to HW control by
AT command.
3.5.1 Activating Sleep Mode
By default, the G600 powers on in Idle Mode. The ATS24 default is 0. In this mode the G600
interfaces and features are functional and the module is fully active. Sleep mode is activated by the
ATS24 command. Such as ATS24 would be activated Sleep mode at soon.
Important: The value of ATS will be saved by re-power G600. But the G600’s default power
on mode is IDLE mode yet.

3.5.2 Serial Interface During Sleep Mode
The G600 wakes up periodically from Sleep mode to page the GSM network for any incoming

HardwareInterfaceDescription
calls or data. After this short paging is completed, G600 returns to Sleep mode. During this short
awake period, the serial interfaces are enabled and communications with the module is possible.
The CTS_N signal is alternately enabled and disabled synchronously with the network paging
cycle. CTS_N is enabled whenever G600 awakes to page the network. The period based on the
DRX permanent of the network.
4.615 ms (TDMA frame duration) * 51 (number of frames) * DRX value.
At the same time, the CTS_N indicates the G600 serial interfaces are active or inactive.
CTS
(DRX=2)
3.5.3 Terminating Sleep Mode
Terminating the Sleep mode, or wake-up, is defined as the transition of the G600 operating
state from Sleep mode to Idle mode. There are several ways to wake-up G600 from Sleep mode
as described below.
Important: During Sleep mode the G600 internal clocks and circuits are disabled, in order
to minimize power consumption. When terminating the Sleep mode, and switching to Idle mode,
G600 requires a minimal delay time to reactivate and stabilize its internal circuits before it can
respond to application data. This delay is typically of 5 ms, and is also indicated by the CTS_N
signal inactive (high) state. The delay guarantees that data on the serial interface is not lost or
misinterpreted.
3.5.3.1 Temporary Termination of Low Power Mode
Temporary termination of Sleep mode occurs when G600 switches from Sleep mode to Idle
mode for a defined period, and then returns automatically to Sleep mode.
Low power mode may be terminated temporarily by several sources, some of which are user
initiated and others are initiated by the system.
