Chapter 2: Hardware Interface Description The following paragraphs describe in details the hardware requirements for properly interfacing and operating the G30 module. Architecture Overview Figure 2-1 below illustrates the primary functional components of the G30.
Architecture Overview The G30 consists of the following blocks: Baseband The baseband IC is combined with the RF transceiver and the power management unit (PMU). This chipset provides all baseband and low power RF band functionality for GPRS/GSM, and includes: • Micro-controller Unit (MCU) for system and user code execution. • Digital Signal Processor (DSP) for voice and data processing. • Serial communications interfaces.
Chapter 2: Hardware Interface Description Operating Modes G30 incorporates several operating modes. Each operating mode is different in the active features and interfaces. Table 2-1 summarizes the general characteristics of the G30 operating modes and provides general guidelines for operation. Table 2-1: G30 Operating Modes Mode Description Features Not Powered VCC supply is disconnected. VRTC is disconnected. The G30 is Off. Any signals connected to the interface connector must be set tri-state.
Power Supply Power Supply The G30 power supply must be a single external DC voltage source of 3.3V to 4.2V. The power supply must be able to sustain the voltage level during a GSM transmit burst current surge, which may reach 2.0A. The G30 interface contacts for the main power supply, are described in Table 2-2. All these contacts must be used for proper operation.
Chapter 2: Hardware Interface Description Figure 2-2 illustrates the power supply behavior during GSM transmission. Figure 2-2: Transmission Power Drops Note: 1 TX slot is shown. It is recommended that the voltage drops during a transmit burst will not exceed 300mV, measured on the G30 interface connector. In any case, the G30 supply input must not drop below the minimum operating level during a transmit burst.
Power Supply Power Consumption Table 2-4 specifies typical G30 current consumption ratings in various operating modes. The current ratings refer to the overall G30 current consumption over the VCC supply. Table 2-4: G30 Current Ratings Parameter 14 Description Conditions Min Typ Max Unit IOFF RTC mode 90 µA IIDLE Idle mode 28 mA ISLEEP Low power mode 1.
Chapter 2: Hardware Interface Description Power On/Off Operation The G30 power on and off process includes two primary phases, which are indicated at the interface connector by the hardware input signal RESET_IN, and the output signal CTS. The RESET_IN is usually an input signal to the G30, and its main function is to initiate HW reset to the G30. However, this signal can also serve as "live indication" signal, and indicate whether G30 is powered on or off.
Power On/Off Operation Figure 2-3 illustrates the G30 power on upon application of a power supply. Figure 2-3: Power Supply Turn-on Turning the G30 On Using PWR_ON The PWR_ON input signal is set high by an internal pull-up resistor whenever a power supply is applied to G30. Therefore, it is recommended to operate this signal using an open collector/drain circuit connection. Asserting the PWR_ON signal low for a minimum of 600 milliseconds (0.6 seconds) and a maximum of 1.
Chapter 2: Hardware Interface Description Turning the G30 Off Using PWR_ON The PWR_ON signal is set high using an internal pull up resistor when power is applied to G30. Asserting the PWR_ON signal low for a minimum of 3 seconds will turn G30 off. This will initiate a normal power-off process, which includes disabling of all applications interfaces (UART, SIM card, audio, etc.) and closing the network connection. Figure 2-5 illustrates the power-off timings when using the PWR_ON signal.
Low Power Mode Low Power Mode The G30 incorporates an optional low power mode, called Sleep Mode, in which it operates in minimum functionality, and therefore draws significantly less current. During low power mode the G30 network connection is not lost. G30 continues to monitor the GSM network constantly for any incoming calls or data. During low power mode, all of the G30 interface signals are inactive and are kept in their previous state, prior to activating low power mode.
Chapter 2: Hardware Interface Description The G30 wakes up periodically from low power mode to page the GSM network for any incoming calls or data. After this short paging is completed, G30 returns to low power mode. During this short awake period, the serial interfaces are enabled and communications with the module is possible. The CTS signal is alternately enabled and disabled synchronously with the network paging cycle. CTS is enabled whenever G30 awakes to page the network.
Low Power Mode Temporary Termination of Low Power Mode Temporary termination of low power mode occurs when G30 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. Using the WKUPI signal The WKUPI signal is an active low input, that is set high by default.
Chapter 2: Hardware Interface Description Data on the Serial interface While G30 is temporarily awake in Idle mode, data may be transmitted on the serial interface. In case data is being transmitted in any direction, G30 will not return to low power mode. This is regardless of the original wake-up reason or source. G30 will remain awake while data is transferred.
Real Time Clock Real Time Clock G30 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 G30 operating modes (Off, RTC, Idle, Sleep), as long as power is supplied above the minimum operating level. The G30 time and date can be set using the following methods: • Automatically retrieved from the GSM network.
Chapter 2: Hardware Interface Description Serial Interfaces G30 includes three completely independent serial communications interfaces, which may be used by the application for several purposes. UART The G30 UART is a standard 8-signal bus. The primary UART is used for all the communications with G30 - AT commands interface, GPRS data and CSD data, programming and software upgrades. The UART signals are active low CMOS level signals.
Serial Interfaces When G30 receives a call, the RI signal (Ring Indication), initiates pulse indication to the host. The RI behavior is shown in Figure 2-11. Figure 2-11: RI Behavior When Receiving a Call Serial Peripheral Interface (SPI) The G30 provides a synchronous SPI-compatible serial interface, used for data logging only, implemented with the synchronous serial controller hardware block of the G30. The SPI is a master-slave protocol: the module runs as a SPI master device.

SIM Interface External SIM Card G30 does not incorporate an on-board SIM card tray for SIM placement. The external SIM must be located on the user application board, external to the G30. The G30 SIM interface includes all the necessary signals, which are routed to the interface connector, for a direct and complete connection to an external SIM. G30 supports dynamic detection of the SIM card, through a dedicated SIM detection signal.
Chapter 2: Hardware Interface Description • To avoid crosstalk between the SIM clock and data signals (SIM_CLK and SIM_DIO), 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.). • The G30 interface does not support SIM programming through the VPP signal. This signal should not be connected to G30.
Audio Interface Audio Interface The G30 audio interface supports several 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. The G30 supports the following audio devices: • Two single-ended and biased mono analog microphone inputs for use in a variety of modes.
Chapter 2: Hardware Interface Description Figure 2-15 shows the microphone circuit and Table 2-9 gives the microphone specifications. Figure 2-15: Handset Microphone Circuit Important: The microphone circuit design depends on the type of microphone device. A series capacitor is required in case a passive microphone is used, or the application provides a separate bias voltage to an active microphone circuit.
Audio Interface Figure 2-16 shows the microphone circuit and Table 2-10 gives the microphone specifications. Figure 2-16: Headset Microphone Circuit Important: The headset microphone circuit design depends on the type of microphone device. A series capacitor is required in case a passive microphone is used, or the application provides a separate bias voltage to an active microphone circuit.
Chapter 2: Hardware Interface Description Figure 2-17 shows a differential speaker circuit, Figure 2-18 shows a single-ended speaker circuit and Table 2-11 gives the speaker specifications. Figure 2-17: Differential Speaker Circuit Important: For safety regulations it is important to place series resistors on the speaker output lines, as illustrated in Figure 2-17.
Audio Interface Important: When implementing a single ended speaker design, it is required to place a series capacitor and resistor on the speaker output line, as illustrated in Figure 2-18. The capacitor should be of low tolerance with values of C = 10-22 uF.
Chapter 2: Hardware Interface Description Important: When implementing a single ended loudspeaker design, it is required to place a series capacitor and resistor on the alert output line, as illustrated in Figure 2-19. The capacitor should be of low tolerance with values of C = 10-22 uF. The resistor value should be R = 0Ω at the design stage, but may be changed to a different value during audio safety testing, in case that alert level limitation is required.
Audio Interface Digital Audio Interface The G30 digital audio interface is a serial Pulse Code Modulation (PCM) bus, which uses linear 2's compliment coding. G30 is the PCM bus master, supplying the clock and sync signals to the application. The G30 digital interface is a 4 signal PCM bus, which includes a bit clock output signal for the bus timing, a frame sync output signal for audio sampling timing, and serial data input and output signals.
Chapter 2: Hardware Interface Description Figure 2-20 illustrates the I2S bus format. Figure 2-20: I2S BUS Format The PCM bus signal's configuration for voiceband audio is: • PCM_CLK - 144 kHz serial clock • PCM_FS - 8 kHz bit-wide frame-sync • PCM_DOUT - 16-bit linear audio data output • PCM_DIN - 16-bit linear audio data input The 16-bit serial data is transferred in both directions after each sync signal's falling edge.
Audio Interface Table 2-14 describes the available audio paths in Basic mode. Table 2-14: Basic Mode Audio Paths Audio Path Input Signal Output Signal Description Handset MIC SPKR_N, SPKR_P Default audio path for speech and DTMF tones and ring. Headset HDST_INT HDST_SPK Alternate path for headset device. Enable by setting HDST_INT interface signal low.
Chapter 2: Hardware Interface Description Audio Programming Interface The G30 incorporates a unique audio programming interface, through AT commands, which controls the following audio features: • Audio Path - Defines the input and output devices for speech, DTMF tones, rings and alerts. • Audio Gain - Defines the amplification (gain) level for input and output audio devices. • Audio Algorithm - Defines the speech processing features for voice calls.
Audio Interface Table 2-16 gives the speech processing features. Table 2-16: Speech Processing Features Feature Default Setting AT Command Basic Advanced Echo Suppression Noise Suppression Sidetone Description ATS96 AT+MAFEAT Disabled Controls the echo and noise suppression. ATS94 AT+MAFEAT Enabled Controls the sidetone. Gain Control The amplification (gain) level for each input and output device can be configured through AT commands.
Chapter 2: Hardware Interface Description 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 G30's audio circuits through the microphone input signals and then are amplified by the G30's internal audio amplifiers.
A/D Interface A/D Interface The G30 includes 3 Analog to Digital Converter (ADC) signals with 12-bit resolution, for environmental and electrical measurements. The ADC signals measure an analog DC voltage level on their inputs which is converted to a 12-bit digital value for further processing by G30 or the user application. The A/D signals operation and reporting mechanism is defined by the AT+MADCM command. Each A/D can be defined to provide several reports: • A single measurement.
Chapter 2: Hardware Interface Description Important: During GSM transmissions the power supply may suffer voltage drops. This can cause frequent and wide changes in the power supply A/D measurements. This should be taken into account when designing and operating the G30 power supply A/D interface. Table 2-18 gives the supply A/D specifications. Table 2-18: Supply A/D Specifications Parameter Conditions Measurement Range Min Typ 3.0 Resolution 10 Max Unit 5.
Controls and Indicators Interface Controls and Indicators Interface The G30 incorporates several interface signals for controlling and monitoring the module's operation. The following paragraphs describes these signals and their operation. Table 2-20 gives a description of the controls and indicators signals. Table 2-20: Controls and Indicators Pin # (81 pin LGA interface) Pin # (70 pin connector interface) 27 25 RESET_IN OC External reset input External reset signal voltage domain.

PU drain. Value at reset: T/OD. 1 36 GPIO5 I/O GPIO Generic digital interfaces voltage domain. Output driver class F. PU/PD class B. 2 38 GPIO6 I/O GPIO Generic digital interfaces voltage domain.
Controls and Indicators Interface Important: The VREF regulator is powered from the G30's main power supply, and therefore any current sourced through this regulator originates from the G30 VCC supply. The overall VCC current consumed by G30 is directly affected by the VREF operation. The G30 current consumption rises with respect to the current sourced through VREF. Table 2-21 gives the VREF specifications. Table 2-21: VREF Specifications Parameter Min Typ Max Unit -3% 2.
Chapter 2: Hardware Interface Description In case the serial interface incorporates hardware flow control signals, the data will be sent according to their state, after the ATS102 delay time has expired. • ATS100 - Defines the application minimal wakeup duration, in seconds, for a single wakeup event. This time definition is required to avoid frequent unnecessary wakeup events and consequent ATS102 delays.
Controls and Indicators Interface A DC resistance below 100kohm (+10%) is defined as a valid antenna connection, and the ANT_DET output signal is set high. Note: Antenna detect indicator is valid after 2 second from power-up only. GPRS Detection The GPRS output signal indicates the network GPRS connection status. When G30 is connected to a GPRS network, this signal is enabled. When G30 is not connected to the GPRS network this signal is disabled.
Chapter 2: Hardware Interface Description Antenna Interface Important: G30 has two basic hardware models that are differ from one another in the antenna interface. The first uses antenna interface with a U.FL connector, and the second uses RF B2B pads in accordance with the table below. When a U.FL connector module is used, the RF B2B pads are not connected, but the design guidelines must be followed.
