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 Power Supply
The G600 power supply must be a single external DC voltage source of 3.3V to 5.2V. The power supply must be able to sustain the voltage level during a GSM transmit burst current serge, which may reach 2.0A. The G600 interface connector has 10 contacts for the main power supply, as described in the table. All these contacts must be used for proper operation.

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

Hardware Interface Description

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.

BATT

300mV max 3.3V min

TX_EN

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: ? 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: Important: When the VBAT power supplied, the G600 module will be turn on automatically. 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.

3.4.2 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

Hardware Interface Description

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: AT command. All of the description about CTS_N, it must be set the UART to HW control by

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.

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.

Incoming Network Data

During Sleep mode, G600 continues monitoring the GSM network for any incoming data, message or voice calls. When G600 receives an indication from the network that an incoming voice call, message or data is available, it automatically wakes up from Sleep mode to alert the application. When G600 wakes up to Idle mode all its interfaces are enabled. Depending on the type of network indication and the application settings, G600 may operate in several methods, which are configurable by AT commands, to alert the application of the incoming data: a) b) c) d)
?

Enable the serial interface's CTS_N Send data to the application over the serial interface. Enable the serial interface's Ring Indicator (RING_N) signal. LPG status indicator

Data on the Serial interface

During Sleep mode, serial communications is limited to short periods, while G600 is paging the network. When the serial interface is active, data can be exchanged between the application and the G600. The G600 will not return to Sleep mode until the serial interface transmission is completed and all the data is processed. Only when the serial interface transfer is completed and the data is processed, G600 will return to Sleep mode automatically, according to the ATS24 settings.

But then G600 will go back to Idle mode if data and CTS_N enabled at the same time. 3.5.3.2 Permanent termination of Sleep Mode The G600 Sleep mode is enabled and disabled by the ATS24 command. ? ATS24 : ATS24 = 0 disables Sleep mode. The value of ATS24 (>0) will be saved but the mode will not be save by re-power G600.

3.6 Real Time Clock
G600 incorporates a Real Time Clock (RTC) mechanism that performs many internal functions, one of which is keeping time. The RTC subsystem is embedded in the PMU and operates in all of the G600 operating modes (Off, Idle, Sleep), as long as power is supplied above the minimum operating level. When main power is not work, backup battery or capacitor can be supplied to RTC by interface connector VBACKUP. When the main power supply and VBACKUP is disconnected from G600, the RTC timer will reset and the current time and date will be lost. On the next G600 power-up the time and date will need to be set again automatically or manually.

3.6.2 RTC Application
The G600 time and date can be set using the following methods: ? Automatically retrieved from the GSM network. In case G600 is operated in a GSM network that supports automatic time zone updating, it will update the RTC with the local time and date upon connection to the network. The RTC will continue to keep the time from that point. ? Using the AT+CCLK command. Setting the time and date manually by this AT commands overrides the automatic network update. Once the time and date are manually updated, the RTC timer will keep the time and date synchronized regardless of the G600 operating state.

3.7 Serial Interfaces
G600 includes one completely independent serial communications interfaces (UART). The G600 UART is a standard 8-signal bus. This UART is used for all the communications with G600 - AT commands interface, GPRS/EGPRS data and CSD data, programming and software upgrades. The UART signals are active low CMOS level signals. For standard RS232 communications with a PC, an external transceiver is required. G600 is defined as a DCE device, and the user application is defined as the DTE device. These definitions apply for the UART signals naming conventions, and the direction of data flow, as described in the figure. DCE G600 GPRS MODULE DTE G600 Pin#

3.8 SIM Interface
The G600 incorporates a SIM interface, which conforms to the GSM 11.11 and GSM 11.12 standards, which are based on the ISO/IEC 7816 standard. These standards define the electrical, signaling and protocol specifications of a GSM SIM card. The G600 does not incorporate an on-board SIM card tray for SIM placement. The SIM must be located on the user application board, external to the G600. The G600 SIM interface includes all the necessary signals, which are routed to the interface connector, for a direct and complete connection to an external SIM. The G600 supports 1.8V or 3.0V SIM card automatic. While the G600 turn on by POWER_ON. At first SIM_VCC output 1.8V voltage for external SIM card communication. If it is not successful SIM_VCC output 2.85V voltage and communicated SIM card again. Important: If SIM_VCC is supplied, remove SIM card is prohibited. Otherwise, it would be

Hardware Interface Description

3.8.2 SIM Design Guidelines
The SIM interface and signals design is extremely important for proper operation of G600 and the SIM card. There are several design guidelines that must be followed to achieve a robust and stable design that meets the required standards and regulations. ? The SIM should be located, and its signals should be routed, away from any possible EMI sources, such as the RF antenna and digital switching signals. ? The SIM interface signals length should not exceed 100 mm between the G600 interface connector and the SIM tray. This is to meet with EMC regulations and improve signal integrity. ? To avoid crosstalk between the SIM clock and data signals (SIM_CLK and SIM_DATA), it is recommended to rout them separately on the application board, and preferably isolated by a surrounding ground plane. ? The SIM card signals should be protected from ESD using very low capacitance protective elements (zener diodes, etc.).

3.9 Audio Interface
The G600 audio interface supports two channel audio devices and operating modes. The audio interface's operating modes, active devices, amplification levels and speech processing algorithms are fully controlled by the host application, through advanced programming options and a versatile AT commands set.

3.9.5 Audio Design
The audio quality delivered by G600 is highly affected by the application audio design, particularly when using the analog audio interface. Therefore, special care must be taken when designing the G600 audio interface. Improper design and implementation of the audio interface will result in poor audio quality. Poor audio quality is a result of electrical interferences, or noises, from circuits surrounding the audio interface. There are several possible sources for the audio noise: ? ? ? Transients and losses on the power supply EMI from antenna radiations Digital logic switching noise

Most of the audio noise originates from the GSM transmit burst current surges (217 Hz TDMA buzz), which appear on the main power supply lines and antenna, but also indirectly penetrate the internal application's supplies and signals. The noises are transferred into the G600's audio circuits through the microphone input signals and then are amplified by the G600's internal audio
G600 GPRS Module Hardware User Manual Page 28 of 41

Hardware Interface Description

amplifiers. To minimize the audio noise and improve the audio performance the microphone and speaker signals must be designed with sufficient protection from surrounding noises. The following guidelines should be followed to achieve best audio performance: ? ? Reference the microphone input circuits to the G600 AGND interface signal. If using single-ended audio outputs, they should be referenced to the G600 AGND interface signal. ? ? ? ? ? Keep the audio circuits away from the antenna. Use RF filtering capacitors on the audio signals. The audio signals should not be routed adjacent to digital signals. Isolate the audio signals by a surrounding ground plane or shields. Filter internal supplies and signals that may indirectly affect the audio circuits, from noises and voltage drops.

3.10 A/D Interface
The G600 includes 3 Analog to Digital Converter (ADC) (2 ADC in 50pins and 1 ADC in 80pins) signals with 12-bit resolution, for environmental and electrical measurements. The ADC signals accept an analog DC voltage level on their inputs and convert it to a 12-bit digital value for further processing by G600 or the user application. In Idle mode, the ADC input is sampled consecutive times by sampling time interval, and the lasted 8 samples are compared and averaged to provide a stable and valid result. In Sleep mode, the ADC is stopped. When the G600 switch to Idle mode, the ADC should be stable after 5mS.

3.10.1 Power Supply ADC
