Regulatory Requirements

The C24 module is compliant with applicable FCC and IC requirements. The integrated system incorporating the C24 module may be subject to further regulations and standards. Motorola strongly recommends that the system integrator seeks professional advice regarding the regulations and standards that apply to their product.

The Federal Communications Commission (FCC) requires application for certification of digital devices in accordance with CFR Title 47, Part 2 and Part 15. This includes Electromagnetic Energy Exposure (EME) testing. As the C24 modem is not a standalone transceiver but is an integrated module, the C24 cannot be tested by itself for EME certification. It is, however, the integrator’s responsibility to have the completed device tested for EME certification.

The C24 module is compliant to FCC and IC requirements allowing use within North America. Use in other regions may require regional "type approvals" which the manufacturer of the final product integration or reseller will be responsible for procuring. It is strongly recommended that professional advice be sought before placing the finished integrated product on the market to establish local approval and marking requirements.

Safety Statement and Requirements

Certain safety precautions must be observed during all phases of the operation, usage, service or repair of any cellular terminal or mobile incorporating the C24 module. The integrator is advised to consider the following general cautions in the context of their integrated system incorporating the C24 module, and to provide the end user with the applicable warnings and advice of safe operation of the equipment.

Failure to comply with these precautions violates safety standards of design, manufacture and intended use of the product. Motorola assumes no liability for customer failure to comply with these precautions.

• The C24 must be operated at the voltages described in the technical documentation

• The C24 must not be mechanically nor electrically changed. Use of connectors should follow

the guidance of the technical documentation

• The integrated product incorporating the C24 module must be evaluated for SAR under

intended use conditions, and suitable text and SAR values be provided to the end user

• No wireless device can guarantee operation at all times due to network or interference

conditions. A user should never rely on a wireless device as the sole means of making emergency calls

• The C24 module complies with all applicable standards and directives, this does not

guarantee that the product it is integrated into complies, expert advice should be sought to identify the applicable regulations and show compliance

Suitable warning statements regarding the use of RF energy in the integrated host system should be given in the end user documentation.

Antenna and Transmission Safety Precautions

User Operation

The C24 module is normally supplied without an antenna, and is compliant with SAR requirements provided the following conditions are observed.

Do not operate your unit when a person is within 8 inches (20 centimeters) of the antenna. A person or object within 8 inches (20 centimeters) of the antenna could impair call quality and may cause the phone to operate at a higher power level than necessary.

Important: The unit must be installed in a manner that provides a minimum separation distance

of 20 cm or more between the antenna and persons and must not be co-located or operate in conjunction with any other antenna or transmitter to satisfy FCC RF exposure requirements for mobile transmitting devices.

Important: To comply with the FCC RF exposure limits and satisfy the categorical exclusion

requirements for mobile transmitters, the requirements described in the following section, “Antenna Installation” , must be met.

Preface

Standards

Antenna Installation

• The antenna installation must provide a minimum separation distance of 20 cm from users

and nearby persons and must not be co-located or operating in conjunction with any other antenna or transmitter.

• The combined cable loss and antenna gain must not exceed +5.3 dBi (800 band). The

combined cable loss and antenna gain must not exceed +4.2 dBi and total system output must not exceed 2.0W EIRP in the PCS (1900) band in order to comply with the EIRP limit of

24.232 (b). OEM installers must be provided with antenna installation instruction and transmitter operating conditions for satisfying RF exposure compliance.

• For system integrations requiring higher antenna gain, or position closer than 20 cm from the

body, SAR compliance testing of the completed product will be required. It is strongly recommended that the system integrator seeks the advice of a suitably accredited test laboratory to develop a test plan and carry out necessary testing.

Chapter 1: Introduction

The C24 is the newest member of Motorola's embedded cellular modules family.

Designed with dual band CDMA operation, embedded GPS receiver, and with 1x Data capabilities, C24 can operate on any CDMA 1x network to provide voice and data communications, and positioning information.

The C24 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 C24 is designed as a complete CDMA communications solution with all the controls, interfaces and features to support a broad range of applications:

• A powerful audio interface.

• A large set of indicators and control signals.

• Several advanced power-saving modes.

• 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 C24 operation.

The C24 control and indication interface extends its capabilities beyond CDMA communications. This includes an A/D and GPIO interface, and a regulated output voltage for supplying external circuits. With these interfaces, the C24 can operate and control external applications and receive feedback from external environment and circuits.

The integrated GPS receiver supports autonomous and assisted modes of operation for a reliable and immediate location determination. The location information is provided in NMEA format or by AT commands, which provides the application flexible design.

The C24 interface design, using a single 70 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 C24 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.

Power Supply

The C24 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 transmit current surge, which may reach 600 mA.

The C24 interface connector has 8 contacts for the main power supply, as described in Ta ble 2- 2. All these contacts must be used for proper operation.

Power Supply Design

Special care must be taken when designing the power supply of the C24. 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 C24 performance.

It is recommended that any voltage drops during transmission will not exceed 300mV, measured on the C24 interface connector. In any case, the C24 supply input must not drop below the minimum operating level during transmission. Dropping below the minimum operating voltage may degrade the module performance.

To minimize the losses and transients on the power supply lines, it is recommended to follow these guidelines:

• Use a 100 uF, or greater, low ESR capacitor on the C24 supply inputs. The capacitor should

be located as near to the C24 interface connector as possible.

• Use low impedance power source, cabling and board routing.

• Use cabling and routing as short as possible.

• Filter the C24 supply lines using filtering capacitors, as described in Table 2-3.

Power On/Off Operation

When the C24 power supply is stable above the minimum operating level and C24 is powered off, only the internal RTC timer is active.

The C24 power on and off process includes two primary phases, which are indicated at the interface connector by the hardware output signals RESET_N and CTS_N.

The RESET_N signal indicates whether C24 is powered on or off.

When this signal is enabled (low), C24 is powered-off. When it is disabled (high), C24 is powered-on.

The CTS_N signal indicates the serial communications interface (UART) status. When this signal is high, the C24 serial interface is disabled. When it is low, the serial interface is enabled, and C24 is ready to communicate.

Important: Do not operate the C24 out of its electrical or environmental limits. Refer to the

specifications chapter for details of these limits.

Turning the C24 On

During a power on process C24 may toggle several interface signals, which are visible to the application. These signals do not represent any valid state or data, and should be ignored by the customer application until completed.

Turning the C24 On Using ON_N

The ON_N input signal is set high, by an internal pull-up resistor whenever a power supply is applied to C24. Therefore, it is recommended to operate this signal using an open collector/drain circuit connection.

Asserting the ON_N signal low for a minimum of 500 milliseconds (0.5 seconds) and a maximum of 1.5 seconds will cause the C24 to turn-on.

Figure 2-2 illustrates the power-on process using the ON_N signal.

Figure 2-2: ON_N Power On Timing

12 C24 Module Hardware Description December 15, 2008

Chapter 2: Hardware Interface Description

Turning the C24 On Using IGN

To turn on C24, the IGN signal must be asserted high. The IGN signal must remain high for the duration of the C24 operation. C24 powers down when the IGN signal is returned to its low state.

Figure 2-3 illustrates the power-on process using the IGN signal.

Figure 2-3: IGN Power On Timing

Turning the C24 Off

There are several ways to turn the C24 off:

• Asserting the ON_N signal low for a minimum of 2 seconds.

• Setting the IGN signal low.

• AT command.

Turning the C24 Off Using ON_N

Asserting the ON_N signal low for a minimum of 2 seconds will turn C24 off. This will initiate a normal power-off process, which includes disabling of all applications interfaces (UART, audio, etc.) and closing the network connection.

December 15, 2008 C24 Module Hardware Description 13

Power On/Off Operation

Figure 2-4 illustrates the power-off timings when using the ON_N signal.

Figure 2-4: ON_N Power Off Timing

Turning the C24 Off Using IGN

The IGN signal may be used to power off C24 only if it was also used to power it on. When the IGN signal is set low, C24 will turn off. This will initiate a normal power-off process, which includes disabling of all applications interfaces (UART, audio, etc.) and closing the network connection.

The IGN signal will not power off C24 before 30 seconds have elapsed since C24 was powered-on. This delay mechanism is implemented to protect C24 from unexpected transients on the IGN line during power up.

Figure 2-5 illustrates the power-off timings when using the IGN signal.

Figure 2-5: IGN Power Off Timing

14 C24 Module Hardware Description December 15, 2008

Chapter 2: Hardware Interface Description

Turning the C24 Off Using AT+MRST

The AT+MRST command initiates a C24 system reset operation, which powers off the C24. This command emulates the ON_N signal operation for power off.

Power Loss shut down

A low power shut down occurs when C24 senses the external power supply is below the minimal operating limit. 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.

December 15, 2008 C24 Module Hardware Description 15

Low Power Mode

The C24 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 C24 network connection is not lost. C24 continues to monitor the CDMA network constantly for any incoming calls or data.

During low power mode, all of the C24 interface signals are inactive and are kept in their previous state, prior to activating low power mode. To save power, all the C24 internal clocks and circuits are shut down, and therefore serial communications is limited.

Activating Low Power Mode

By default, the C24 powers on in Idle mode. In this mode the C24 interfaces and features are functional and the module is fully active.

Low power mode is activated by the ATS24 command. The value set by this command determines the inactive state duration required by C24, in seconds, after which C24 will enter sleep mode.

For example:

ATS24 = 1 activates low power mode after 1 second of inactivity.

ATS24 = 5 activates low power mode after 5 seconds of inactivity.

ATS24 = 0 disables low power mode (default).

Figure 2-6 illustrates the ATS24 command operation.

Figure 2-6: A TS24 Operation

Important: C24 will not enter low power mode in any case when there is data present on the

serial interface or incoming from the network or an internal system task is running. Only when processing of any external or internal system task has completed, and C24 is inactive for the duration of ATS24, it will enter low power mode.

16 C24 Module Hardware Description December 15, 2008

Chapter 2: Hardware Interface Description

Serial Interface During Low Power Mode

During low power mode the C24 serial interfaces are disabled. This is indicated by the CTS signal high state.

The C24 wakes up periodically from low power mode to page the network for any incoming calls or data. After this short paging is completed, C24 returns to low power 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 C24 awakes to page the network. This indicates the C24 serial interfaces are active (see Figure 2-7).

Figure 2-7: CTS Signal During Sleep Mode

The periodical enabling and disabling of the CTS_N signal during low power mode can be controlled by the AT+MSCTS command.

Setting AT+MSCTS=1 permanently disables the serial interface during low power mode, even during a network page by C24. The CTS_N signal is disabled, and therefore the serial interfaces are blocked.

Terminating Low Power Mode

Terminating the low power mode, or wake-up, is defined as the transition of the C24 operating state from Sleep mode to Idle mode. There are several ways to wake-up C24 from low power mode as described below.

Important: During power saving mode the C24 internal clocks and circuits are disabled, in

order to minimize power consumption. When terminating the power saving mode, and switching to Idle mode, C24 requires a minimal delay time to reactivate and stabilize its internal circuits before it can respond to application data. This delay is typically of 15 milliseconds, 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.

December 15, 2008 C24 Module Hardware Description 17

Low Power Mode

Temporary Termination of Low Power Mode

Temporary termination of low power mode occurs when C24 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_N signal

The WKUPI_N signal is an active low input, which is set high by default. By asserting this signal low the application can wake-up C24 from low power mode and switch to Idle mode.

C24 will remain in Idle mode, awake and fully active, as long as WKUPI_N signal remains low. When this signal is disabled and set high again, C24 will return to Sleep mode automatically, according to the ATS24 settings (see Figure 2-8).

Figure 2-8: WKUPI_N Signal Operation

The WKUPI_N signal is the recommended method to temporarily wake-up C24 from low power mode. It provides the application full control of the C24 operating mode and guarantees that data on the serial interface will not be lost or misinterpreted.

The WKUPI_N signal must be used to wake up C24 from low power mode if the serial interface has been disabled by the AT+MSCTS command.

Incoming Network Data

During low power mode, C24 continues monitoring the CDMA network for any incoming data, message or voice calls.

When C24 receives an indication from the network that an incoming voice call, message or data is available, it automatically wakes up from low power mode to alert the application. When C24 has completed to process all the tasks related to the incoming data, it will automatically return to low power mode according to the ATS24 settings.

Depending on the type of network indication and the application settings, C24 may operate in several methods, which are configurable by AT commands, to alert the application of the incoming data:

• Enable the WKUPO_N signal to wake-up the application from low power.

18 C24 Module Hardware Description December 15, 2008

Chapter 2: Hardware Interface Description

• Send data to the application over the serial interface.

• Enable the serial interface's Ring Indicator (RI_N) signal.

Data on the Serial interface

While C24 is temporarily awake in Idle mode, data may be transmitted on the serial interface. In case data is being transmitted in any direction, C24 will not return to low power mode. This is regardless of the original wake-up reason or source. C24 will remain awake while data is transferred.

Only when the serial interface transfer is completed and the data has been processed, C24 will return to low power mode automatically, according to the ATS24 settings (see Figure 2-9).

Figure 2-9: Serial Interface Data

Permanent termination of Low Power Mode

The C24 low power mode is enabled and disabled by the ATS24 command.

To permanently terminate the C24 low power mode, the ATS24 = 0 command must be used. Setting ATS24 = 0 disables the currently active low power mode and switches C24 to Idle mode.

C24 will not return to low power mode until an ATS24 > 0 commands is set again.

This command can be sent only when the serial interface is active.

In case the serial interface is disabled, it must first be activated before sending this command. To reactivate the serial interface, a temporary termination of the low power mode is required, as described in “Temporary Termination of Low Power Mode” on page 18.

Following the temporary low power mode termination, the serial interface will activate and the ATS24 = 0 command can be received by C24.

December 15, 2008 C24 Module Hardware Description 19

Real Time Clock

C24 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 PMIC and operates in all of the C24 operating modes (Off, Idle, Sleep), as long as power is supplied above the minimum operating level.

The C24 time and date can be set using the following methods:

• Automatically retrieved from the network.

C24 operates in a CDMA 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 C24 operating state.

When the power supply is disconnected from C24, the RTC timer will reset and the current time and date will be lost. On the next C24 power-up the time and date will be set again automatically or manually.

Serial Interfaces

C24 includes three completely independent serial communications interfaces, which may be used by the application for several purposes.

Primary UART (UART1)

The C24 primary UART is a standard 8-signal port for RS232. The UART is used for all the communications with C24 - AT commands interface, 1x 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.

C24 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 Figure 2-10.

Chapter 2: Hardware Interface Description

Figure 2-10: UART1 Interface Signals

The C24 primary UART supports baud rates 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 and 230400 bps.

Auto baud rate detection is not supported and the default baud rate is 115200 bps.

All flow control handshakes are supported: hardware, software, or none.

The UART default port configuration is 8 data bits, 1 stop bit and no parity, with hardware flow control and 115200 baud rate.

Secondary UART (UART2)

The secondary UART is a 4-signal interface, which only provides data and flow control signals. The secondary UART is used to communicate GPS data in NMEA format.

The UART signals are active low CMOS level signals. For standard RS232 communications with a PC, an external transceiver is required.

Serial Interfaces

Figure 2-11: UART2 Interface Signals

The UART default port configuration is 8 data bits, 1 stop bit and no parity, with hardware flow control and 115200 baud rate.

Important: The UART2 interface can't be operated together with the UIM Card interface. Both

interfaces share the same internal HW port. Therefore, applications using the UART2 interface must not connect any external devices to the UIM Card interface, and vise versa.

USB Interface

C24 incorporates a standard Universal Serial Bus (USB) interface.

The C24 USB electrical interface and protocol conform to the USB 2.0 full-speed specifications. C24 is defined as a USB device on the USB bus and does not support hub or host functionality.

The USB interface provides the following services:

• Standard communications with C24, as done through the UART1 interface

• FW programming

• Data logging for application debug

• Output of GPS location data in Binary and NMEA format

The USB interface signals are shown in Figure 2-12.

22 C24 Module Hardware Description December 15, 2008

UIM Interface

The C24 incorporates a UIM interface, which conforms to the ISO/IEC 7816 standard which defines the electrical, signaling and protocol specifications of a UIM card.

C24 does not incorporate an on-board UIM card tray for UIM placement. The UIM must be located on the user application board, external to the C24. The C24 UIM interface includes all the necessary signals, which are routed to the interface connector, for a direct and complete connection to an external UIM.

C24 supports dynamic detection of the UIM card, through a dedicated UIM detection signal. C24 will detect a UIM card insertion or removal upon power up or during operation by the transitions on the UIM_PD_N signal.

Important: The UIM interface can't be operated together with the UART2 interface. Both

interfaces share the same internal HW port. Therefore, applications using the UIM interface must not connect any external devices to the UART2 interface, and vise versa.

Figure 2-13 illustrates a typical UIM interface connection to C24. This connection type is

implemented on the C24 Developer Board, using an FCI SIM tray, PN 7111S1615A05.

UIM Design Guidelines

The UIM interface and signals design is important for proper operation of C24 and the UIM card. Below are several design guidelines that must be followed to achieve a robust and stable design that meets the required standards and regulations.

• Two 100nF low ESR capacitors must be placed, in parallel, on the UIM_VCC signal line.

The capacitors should be located as near as possible to the UIM card tray contacts. The capacitors value may slightly change depending on the application design.

• A 56Ω series resistor must be placed on the UIM_DIO signal line.

The resistor value may slightly change depending on the application design.

• A 100Ω series resistor must be placed on the UIM_CLK signal line.

The resistor value may slightly change depending on the application design.

• It is recommended to design component placeholders (unpopulated) for capacitors on the

UIM_RST and UIM_DIO signal lines.

• The UIM card tray should be located, and its signals should be routed, away from any

possible EMI sources, such as the RF and digital switching signals.

• The UIM interface signals length should not exceed 100mm between the C24 interface

connector and the UIM tray.

• The UIM clock and data signals (UIM_CLK and UIM_DIO) should be routed separately on

the application board, and preferably isolated by a surrounding ground plane.

• In case that transient suppressors (zener diodes, etc.) are used by the application on the UIM

card signals, individual package components (not arrays) with low capacitance should be used.

• The C24 interface does not support UIM programming through the VPP signal. This signal

should not be connected to C24.

• Using the UIM detection signal (UIM_PD_N) is mandatory in case that the UIM card is

accessible to the user, and may be removed during C24 operation. To avoid damage to the UIM or C24, the UIM interface signals must be deactivated before the UIM card is mechanically removed from the UIM tray contacts. Therefore, the UIM_PD_N detection signal must be disabled before the UIM is removed from the tray.

Audio Interface

The C24 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 C24 supports the following audio devices:

• Two single-ended and biased analog microphone inputs for use in a variety of modes.

• Two differential analog speaker outputs for use in a variety of modes.

• A digital serial interface using PCM coding.

Figure 2-14 shows the audio interface topology.

Handset Microphone Port

The handset microphone port is the C24 power-up default active audio input for voice calls. It is located on pin 61 at the C24 interface connector, named MIC.

It is designed as a single-ended input and should be referenced to the C24 analog ground.

The microphone input includes all the necessary circuitry to support a direct connection to an external microphone device. It incorporates an internal bias voltage of 1.8V through a 2.2kΩ resistor, and has an impedance of 1kΩ.

December 15, 2008 C24 Module Hardware Description 27

Audio Interface

It is designed as a differential output with 32Ω impedance, but may also be used as a single-ended output referenced to the C24 analog ground.

The speaker output is used for both the handset and the headset audio paths.

Figure 2-17 shows a differential speaker circuit, Figure 2-18 shows a single-ended speaker circuit

and Table 2-8 gives the speaker specifications.

Important: For safety regulations it is important to place series resistors on the speaker output

lines, as illustrated in Figure 2-17. The resistors value should be R = 0

28 C24 Module Hardware Description December 15, 2008

Chapter 2: Hardware Interface Description

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. The resistor value depends on the speaker application:

- For a handset device, the resistor value should be R = 0

Ω at the design stage, but

may be changed to a different value during audio safety testing, in case speaker level limitation is required.

- For a headset device, safety regulations require the resistors value to be R > where R

is the speaker impedance (e.g. 32Ω).

For example, when using a 32Ω speaker the series resistance would be R > 64Ω.

Headset Detection

The C24 operates by default in the basic audio mode with the handset audio path, for DTMF tones and speech, and the alert loudspeaker port, for rings and alert tones.

The headset path is an alternate audio path in basic mode. It is designed for, but not limited to, a personal hands-free audio device, a headset, using the headset microphone input port and the speaker output port.

The HDST_INT_N signal is used to switch between handset and headset audio paths in basic audio mode. This signal is set high by default at power up. Asserting the HDST_INT_N signal low enables the headset audio path and disables the handset and alert paths. Setting this signal high will disable the headset path and enable the handset and alert audio paths.

The C24 supports dynamic switching between the handset and headset audio paths, during operation and call handling.

Important: The HDST_INT_N signal does not operate in advanced audio mode. This signal's

functionality is overridden by the AT+MAPATH command settings.

Alert Loudspeaker Port

The alert loudspeaker is the default C24 power-up ringer. It is used for, but not limited to, sounding the C24 alerts, melodies, and rings. It is located at pins 63 and 65 on the C24 interface connector, named ALRT_N and ALRT_P respectively.

It is designed with an internal amplifier supplied directly from VCC, which supplies 0.5W to the audio device. It may also be used as a single-ended output referenced to the C24 analog ground.

Digital Audio Interface

The C24 digital audio interface is a serial Pulse Code Modulation (PCM) bus, which uses linear 2's compliment coding. C24 is the PCM bus master, supplying the clock and sync signals to the application.

The C24 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.

The PCM bus signal's configuration is:

• PCM_CLK - 2048 kHz serial clock

• PCM_FS - 8 kHz bit-wide frame-sync

• PCM_DOUT - 13-bit linear audio data output

• PCM_DIN - 13-bit linear audio data input

The analog audio is sampled at an 8 kHz rate and converted to linear 13-bit serial PCM audio data. The serial data is transferred on the PCM bus in 16-bit word format, which includes 13 sampled data bits, and 3 added zero value bits.

The 16-bit serial data is transferred in both directions after each sync signal's falling edge. The sync signal pulse duration is one clock period, after which the serial data is transferred in both directions for 16 consecutive clock periods.

Following the 16-bit data transfer, the serial input and output data signals inactivate until the next sync pulse, which occurs every 125 µS (8 kHz). It is recommended the serial data signals will be High-Z during the inactive period.

Audio Design

The audio quality delivered by C24 is highly affected by the application audio design, particularly when using the analog audio interface. Therefore, special care must be taken when designing the C24 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 DC supply current, 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 C24's audio circuits through the microphone input signals and then are amplified by the C24's internal audio 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 & speaker circuits to the C24 AGND interface signal.

• Keep the audio circuits away from the antenna.

• Use RF filtering capacitors on the audio signals, as described in Table 2-3.

• 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.

36 C24 Module Hardware Description December 15, 2008

Chapter 2: Hardware Interface Description

Analog Ground

The C24 interface incorporates a dedicated analog ground contact, AGND pin 59, which is internally connected to the C24's ground. The AGND signal is intended to provide a separate ground connection for the application's external audio devices and circuits.

This signal provides an isolated ground connection directly from C24, which is separated from the noisy digital ground of the application. It is recommended to connect this signal to analog audio devices and circuits used by the application. Using a separate analog ground minimizes audio noises and improves the audio circuit's immunity from external interferences.

December 15, 2008 C24 Module Hardware Description 37

A/D Interface

The C24 includes 4 Analog to Digital Converter (ADC) signals with 8-bit resolution, for environmental and electrical measurements. The ADC signals measure an analog DC voltage level on their inputs which is converted to an 8-bit digital value for further processing by C24 or the user application.

The A/D signals operation and reporting mechanism is defined by the AT+MMAD command.

Table 2-16 below, lists the internal and external A/D signals provided by C24.

General Purpose A/D

The C24 provides 3 general purpose A/D (GPAD) signals for customer application use. Each A/D signal can monitor a separate external voltage and report its measured level independently to the application, through the AT command interface.

The GPAD signals measure a DC voltage level of 0.1 - 2.5 V, which is converted internally to a 8-bit digital value. The user application can monitor the A/D voltage level through the AT+MMAD command, which returns the measured DC level in Volts times 100.

For example, a measured analog DC level of 1.75 Volts will be presented as 175 by the MMAD command.

Reset

The RESET_N output signal indicates the C24's operating status. This signal is set high after power up, when C24 is operating. It is set low when C24 is powered off.

When the RESET_N signal is low, the C24 interface signals are disabled and do not represent any valid data or state. Furthermore, any input signals connected to the C24 interface must be disabled (tri-state) or set low when RESET_N is low.

VREF Reference Regulator

The C24 incorporates a regulated voltage output, VREF. The regulator provides a 2.8V output for use by the customer application. This regulator can source up to 150 mA of current to power any external digital circuits.

40 C24 Module Hardware Description December 15, 2008

Chapter 2: Hardware Interface Description

Important: The VREF regulator is powered from the C24's main power supply, and therefore

any current sourced through this regulator originates from the C24 VCC supply. The overall VCC current consumed by C24 is directly affected by the VREF operation. The C24 current consumption rises with respect to the current sourced through VREF.

Wakeup Out

Some applications incorporate their own power saving mode, in which they operate with minimal functionality, including disabling of interfaces and serial communications.

The wakeup-out (WKUPO_N) signal is an active low output, which is designed to support a low power mode feature in the host application. This signal is used by C24 to indicate that it requires to communicate with the host application through the serial interface, due to an incoming call or data, or an unsolicited event. Applications that incorporate a low power mode should use this

December 15, 2008 C24 Module Hardware Description 41

Controls and Indicators Interface

signal as an indication to switch from low power mode to normal operation, and activate the serial interface.

The wakeup-out mechanism, using the WKUPO_N signal, is controlled by 2 AT commands (see

Figure 2-24):

• ATS102 - Defines the delay time in milliseconds that C24 will wait, after asserting the

WKUPO_N signal low, before sending data on the serial interface. This delay is required to allow the application enough time to reactivate from low power mode and switch to normal mode. If ATS102=0, which is the default value, the WKUPO_N signal and mechanism is disabled. 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. The application may return to low power mode after the serial interface has been inactive for the duration set by ATS100. This duration is measured from the last data sent or received on the serial interface.

Figure 2-24: WKUPO_N Operation

The following guidelines apply to the wakeup-out mechanism:

• C24 will set the WKUPO_N signal low to indicate that in has data to send through the serial

interface.

• C24 will start sending the data to the application after the delay defined by ATS102.

• The WKUPO_N signal will remain low while data is being sent to the host application.

• The host application should keep its serial interface active, and not switch to low power

mode, while the WKUPO_N signal is low.

• C24 will set the WKUPO_N signal high when it has completed sending the data.

• The application serial interface must stay active, and not switch to low power mode, for the

duration set by ATS100, after WKUPO_N is set high.

• C24 will not set the WKUPO_N signal low if it needs to send additional data during the

ATS100 delay time.

• The application may switch to low power mode after the WKUPO_N signal is set high and

the serial interface has been inactive for the duration set by ATS100.

Chapter 2: Hardware Interface Description

Antenna Detection

The C24 incorporates an internal antenna detection circuit, which senses the physical connection and removal of an antenna or antenna circuit on the C24 antenna connector. The antenna detection state is reported to the application through the ANT_DET output signal, and may also be queried by the ATS97 command.

The detection circuit senses DC resistance to ground on the C24 antenna connector.

A DC resistance below 100kohm (+ ANT_DET output signal is set high.

10%) is defined as a valid antenna connection, and the

CDMA Network Indicator

The CDMA output signal indicates the network CDMA connection status. When C24 is connected to a CDMA network, this signal is enabled. When C24 is not connected to the CDMA network this signal is disabled.

Transmission Indicator

The TXEN_N output signal indicates when C24 is transmitting over the CDMA network. This signal is set low during transmission, and set high when no transmission is in progress.

General Purpose I/O

The C24 incorporates 8 general purpose IO signals for the user application. Each GPIO signal may be configured and controlled by AT command. These signals may be used to control or set external application circuits, or to receive indications from the external application.

GPS Interface

The C24's integrated GPS receiver can provide location and position information based on the Global Positioning System satellites.

The GPS interface supports the following modes of operation:

• Autonomous - In this mode the GPS receiver operates stand alone, regardless of CDMA

• Assisted - In this mode the C24 operates in conjunction with the CDMA network to search

network availability. The C24 searches and detects available satellites, and calculates the positioning information on its own.

for satellites and calculate the positioning data.

• MS Assisted - The calculation is performed by the network and the position is send to the

C24 device.

• MS Based - C24 receive initial satellites information form the network and calculatse the

position by itself.

Number of satellites

2D - When the GPS receiver is using three satellites to determine a position solution.

3D - When the GPS receiver is using four or more satellites to determine a position solution and the accurate time.

Serial Configuration

The C24 has two modes of data: Binary and NMEA.

Binary Mode is reported through UART1 or USB while the NMEA is through UART2 and USB.

Accuracy

The accuracy must be less than 50 meters 67% of the time, and 150 meters 95% of the time.

C24 Mounting

The C24 incorporates 2 mechanical holes for installing the module onto the application board. The holes are 2.4 millimeters in diameter, which accommodates several types of mechanical elements.

Several mechanical approaches may be applied to mount and fasten C24 to the application board. Using M2 screws with suitable washers to mount the module onto spacers, a bracket or chassis is a recommended design.

Special attention must be paid to the area surrounding the C24 mounting holes. A grounding pad of 4.4 milimeters in diameter surrounds these holes. The diameter and area of this pad must not be exceeded by any mechanical or electrical element. Several electrical components, which are not shielded, are located near the holes. These components must not be in contact with the mounting elements or with other parts of the application board, and care must be taken to avoid any damage.

Figure 4-6 depicts the C24 mounting area.

Figure 4-6: C24 Mounting Area

The holes are used for mechanical mounting of C24 to the application board but also for grounding support. Using conductive elements to install C24 significantly improves the overall grounding of the module and therefore improves the C24 performance and stability.

It is required to use screws or other mechanical elements to fasten C24 to the application board, but it is highly recommended to use conductive elements to improve the module's performance.

Testing a Standalone Unit

This section describes how to perform a C24 functionality test, whose purpose is to:

• Introduce the user to the C24

• Explain how to work with the C24 unit

• Describe how to evaluate basic C24 features

The test setup provides a wide platform through which a C24 unit can be evaluated. The specific test procedure described below covers only a few of the C24’s many features. Using this setup, you can perform several additional tests on the C24.

The test is performed using two modems, one of which is the C24. The modems communicate with each other through a single computer, which also controls their operation.

The test requires knowledge about the operation of the C24 Developer’s Kit, terminal applications and AT commands. Refer to relevant documentation for assistance.

To perform the test, you need the following:

• A C24 OEM cellular engine unit

• A C24 Developer's Kit

• A desktop or laptop computer, which includes: – A free serial communications port (RS232) – A connected and active line modem (internal or external) – A terminal application (such as HyperTerminal)

Test Setup

To Setup the C24 Test

Follow this procedure (Figure 5-1) to set up your equipment before performing the test:

1. Verify that the computer you intend to use for the test is equipped with a working

line modem

You can use a second C24 unit instead of the line modem. When doing so, you must repeat the setup procedure that follows for the additional C24.

2. Set up the C24 and the Developer Board as described in “Initial Setup” in

“Chapter 2: Developer Board and Interfaces Description” in the “C24 Developer’s Kit” (Motorola part no. 6802985C53)

3. Verify that the C24 has adequate reception from the local network

4. Connect the Developer Board’s RS232 port to the computer’s serial port

5. Open a terminal application window (such as HyperTerminal) and configure it to operate

• ati8—prompts the C24 software version

3. Make a CSD call from the C24 to the line modem or the reverse using the

commands in the appropriate window

4. Verify that a connection between the two modems is established

5. Select any file to transfer between the two modems

The file can be any existing file, or a new file created specifically for the test.

6. Send the file either from the C24, or to the C24, through the terminal application using the

terminal application’s send/receive file options

7. When the file transfer is complete, use the

ath command in any of the terminal windows to

terminate the call

This step completes the test. You can now continue to perform additional tests using the same setup, or change the setup as required.
