2.5.2 Regulatory Requirements

The Federal Communications Commission (FCC) requires application for certification of digital devices in accordance with Part 22 and Part 24. This includes Electromagnetic Energy Exposure (EME) testing. As the c18 modem is not a standalone transceiver but is an integrated module, the c18 cannot be tested by itself for EME certification. It is, however, the integrator’s responsibility to have the completed device tested for EME certification.

2.5.3 Regulatory Statement

The following safety precautions must be observed during all phases of the operation, usage, service or repair of any cellular terminal or mobile incorporating the c18 module. Manufacturers of the cellular terminal are advised to convey the following safety information to users and operating personnel, and to incorporate these guidelines into all manuals supplied with the product. 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.

1. The c18 must be operated at the voltages described in the technical documentation.

2. The c18 must not be mechanically nor electrically changed. Use of connectors should follow the guidance of the technical documentation.

10 98-08901C63-A

Introduction

3. Systems using the c18 are subject to mandatory EMC testing under directive 89/336/EEC. Other directives, such as the LVD directive 73/23/EE, may also apply to a system using the c18 module.

2.6 SAFETY PRECAUTIONS

c18 modules are not ESD protected. ESD preventive measures must be taken when handling the modules. Integrators should design ESD protection on all external interfaces.

Caution

When using the headset earpiece, verify the audio level as a safety precaution and limit the maximum voltage by the serial resistor. See “Headset Interface” on page 30.

Warning

2.6.1 User Operation

Do not operate your telephone 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. In addition, it may expose that person to RF energy in excess of that established by the FCC RF Exposure Guidelines.

The telephone must be installed in a manner that provides a minimum separation distance of 20 cm or more between the antenna and persons in order to satisfy FCC RF exposure requirements for mobile transmitting

Warning

devices.

To comply with the FCC RF exposure limits and satisfy the categorical exclusion requirements for mobile transmitters, the requirements described in this manual must be met.

2.6.2 Antenna Installation

Output power listed is conducted at antenna terminals. This OEM module transmitter operates with external vehicle-mounted antennas. OEM installers must follow the antenna installation instructions of the antenna manufacturer, and must meet transmitter operating conditions for satisfying RF exposure compliance. In addition, the following conditions must be met:

• The antenna installation must provide a minimum separation distance of 20 cm from users and nearby persons, and must not

be co-located or operated in conjunction with any other antenna or transmitter.

• The combined cable loss and antenna gain must not exceed +6.1 dBi. The total system output must not exceed 1.5 Watts ERP

(Cellular)/3.0 Watts EIRP (PCS) to qualify for the categorical exclusion requirements of 2.1091.

The RF block transmitter and receiver support 800/1900MHz CDMA and 800MHz AMPS. In addition, the E911 FCC requirement for Assisted GPS (aGPS) is also supported.

c18 module interfaces use the following three types of connectors:

• 70-pin, 0.5mm pitch, board-to-board connector

• 36-pin ZIF (Zero Insertion Force) connector

• 28-pin DIN connector

98-08901C63-A 13

Hardware Description

The RF output ports are MMCX-type, 50-ohm matched connectors, as follows:

• Cellular antenna connector for 800/1900 MHz and passive aGPS

• GPS antenna connector that supports an aGPS active antenna

19.2MHz

The receiver uses a superhetrodyne architecture, which down-converts to an IF frequency and then to the baseband. The received signal enters either the passive tri-band antenna, which supports cellular 800 MHz/1900 MHz and aGPS, or the active GPS antenna, which supplies the required bias voltage for the active antenna circuitry. The signal is directed via the appropriate duplexer to the programmable RFR3300 IC, where it undergoes preamplification (three LNAs, with one for each band) before being down-mixed to the IF frequency of 183.6MHz and filtered. From there, the signal enters the IFR3300 IC, where it is amplified to the required level with AGC circuitry, quadrature down-converted to baseband, filtered and sampled. The sampled signal is then fed to the DSP section.

3.1.2.2 Transmit Path

The transmitter also uses a superhetrodyne architecture in which the signal is up-converted from baseband to IF and then to the transmit frequency. The IQ baseband signals enter the RFT3100 IC, which quadrature up-converts to the IF frequency and then to the transmit frequency using a single side-band up-converter, in order to eliminate the need for expensive IF filtering circuitry. The signal is amplified to the required power level using the AGC circuitry. The signal is then fed into the power amplifiers via Tx cleanup filters, which preserve the spectral purity. From there, the signal passes to the appropriate duplexer. The signal then enters the power detection circuitry, which comprises a directional coupler and a detector. The power detection circuitry feeds voltage proportional to the transmitted signal power back to the logic circuitry, thereby enabling proper power control.

Hardware Description

3.1.2.3 Frequency Generation

There are three RF frequencies generated to enable frequency conversions within the radio:

• Front-end-down and Front-end-up Conversion LO Frequency: The frequency plan is designed so that the Rx front-end-down

conversion LO and the Tx front-end-up conversion LO are the same frequency, which is generated in the dual synthesizer IC. This LO is fed into the RFR3300 IC, where it drives the down-convert mixers and from where it is also redirected to the RFT3100 IC, where it drives the single sideband up-convert front-end mixers. The basic synthesizer frequency is around 2 GHz, which supports the 1.9GHz band. The internal divide-by-two circuitry within the RFR3300 is able to produce one-half the LO frequency to support the 800MHz band as well.

• The frequency required for the quadrature down-convert LO (translating the signal from IF to baseband) is generated from

the dual-synthesizer IC, as well as from an on-chip VCO in the IFR3300 IC.

• The quadrature up-convert LO (translating the signal from baseband to IF) is generated from an on-chip synthesizer on the

RFT3300 IC, as well as from an external VCO and loop filter circuitry.

All frequency generation uses a common 19.2MHz x-stall reference oscillator.

Hardware Description

3.1.2.4.1 Power Management

The power management block consists of the PM1000, which supplies most of the required regulated voltages, as well as a separate LDO that supplies the FLASH core.

3.1.2.4.2 Digital Processing

The MSM5100 block performs all digital processing for the c18 module. This block contains the following module peripherals:

• UART1

• UART2

• R-UIM

•Keypad

•USB

•CODEC

• General-purpose A/D converter

3.1.2.5 Memory Block

The memory block consists of SRAM and Flash components. The c18 module contains 2 MB of SRAM and 8 MB of flash memory. The module can accommodate an additional 8 MB flash, if required.

3.1.2.5.1 External Interfaces

The c18 module interfaces contain a USB transceiver, filters, an external interface connector (a 70-, 36- or 28-pin connector, depending on the model), audio circuitry and a harness IC, which provides the interface to the serial LCD modules and additional GPIOs.

3.2 POWER SUPPLY AND CURRENT CONSUMPTION

The c18 is designed to operate from a single voltage source. The module obtains its voltage supply via four VCC and four GND pins (models with a 70-pin or 36-pin interface connector), or via two VCC and two GND pins (models with a 28-pin connector). The source voltage must be between 3.6 V DC and 4.5 V DC (4.0 V nominal) on the c18 interface connector pins (across the VCC and GND pins). To be able to function at the lowest supply voltage, it is important to compensate for any losses in the power supply lines and user PCB. The voltage source must be capable of providing sufficient current to the module (approximately 1 A). If additional loads are driven by the voltage source (such as backlights, LCD, and so on.), an additional current load should be accommodated.

GND pins are used as power and signal ground pins. All signals, except audio signals, are referenced to GND. All single-ended audio signals are referenced to AGND. See “Audio Interfaces” on page 28.

16 98-08901C63-A

Hardware Description

3.2.1 Current Consumption

In order to correctly design the power supply or battery for the c18, integrators should take into account the current consumption of the c18 in its various operating modes. The c18 is a CDMA phone that transmits in continuous mode. Table 6 lists the maximum current for each mode supported by the c18 module.

Hardware Description

3.4 TURNING THE UNIT ON/OFF

This section describes the methods available to turn the c18 unit on and off.

3.4.1 On/Off Circuitry

The unit does not power-up automatically by connecting the power. There are two ways to turn on the c18 unit:

• Using the AUDIO_OUT_ONOFF pin

• Using the Ignition pin

It is recommended to use the AUDIO_OUT_ONOFF line to power-on or power-off the c18.

The module should not be turned off by removing the supply voltage. If the c18 is powered off by disconnecting the power to the unit, the c18 module does not shut down properly and does not complete the deregistration procedure

Caution

from the network.

3.4.2 Turning the Unit On/Off Using the AUDIO_OUT_ONOFF Pin

The c18 module can be turned on or off using the AUDIO_OUT_ONOFF line (pin #53 on the 70-pin connector, pin #14 on the 36-pin ZIF connector and pin #17 on the 28-pin DIN connector). The AUDIO_OUT_ONOFF line has dual functions, as follows:

• It serves as an audio output.

• It serves as an on/off signal.

It is internally pulled high, to approximately VCC -0.6V.

To turn the modem on, the AUDIO_OUT_ONOFF signal should be pulled to GND through a 4.7K resistor for a minimum of two seconds. The signal should then be released, and the module will begin the power-up sequence. During the next six to seven seconds, the module does not communicate (for example, it does not respond to AT commands if configured for RS232 communication). For a detailed description of UART signals at power-up, see “UART1” on page 24.

When using this signal as audio output, make sure to decouple the load with a capacitor. Connecting a load directly without the capacitor alters proper module functionality. For more details concerning the audio interface, see

Note

To turn the module off, the AUDIO_OUT_ONOFF signal should be pulled to GND through a 4.7K resistor for a minimum of two seconds. The signal should then be released. This initiates the power-down sequence, which includes deregistration from the network. The process takes approximately three to eight seconds (typically five seconds). After the module has powered down, the voltage supply can be disconnected from the module.

Caution

“Hands-free Audio (Auxiliary Audio) Interface” on page 30.

18 98-08901C63-A

The timing for these processes is shown in Figure 6 and Figure 7 below.

Hardware Description

Figure 6. Powering On the c18 Power Using the AUDIO_OUT_ONOFF Pin

Figure 7. Powering Off the c18 Using the AUDIO_OUT_ONOFF Pin

98-08901C63-A 19

Hardware Description

3.4.3 Turning the Unit On Using the Ignition Pin

An alternative way to power-up the module is to connect the Ignition line to a 12 V input (for example, a car battery). Releasing the Ignition line causes the module to power-down after a timeout period defined by flex, provided that the module is not in the midst of a call and that no keys have been pressed. If the module was involved in a call, the module turns off after a timeout period defined by flex, after the call ends.

The c18 module does not enter power-save modes when the Ignition line is asserted high.

Note

The Ignition line is used to turn on the c18 unit, and is primarily used for units connected to a mobile device, where current consumption is not a major concern. When the Ignition line rises, the unit turns on. The Ignition line is also used to turn the unit on when power is connected to the unit (for example, the Ignition line in a car kit).

For proper Ignition line functioning, c18 VCC must be 4.0V or higher. Proper Ignition line functioning is not guaranteed at less than 4.0V VCC.

Note

3.5 SLEEP MODE OPTIONS

This section describes c18 Sleep mode options.

3.5.1 c18 Awakens the DTE from Sleep Mode

In order to awaken the DTE from Sleep mode (or to block the DTE from entering Sleep mode), the c18 (DCE) changes its WAKE_OUT line state prior to sending data, thereby prompting the DTE to exit Sleep mode. The following compatibility issues apply:

• For g18 compatibility:

To wake up the DTE, the c18 changes the WAKE_UP line state to low for the time interval designated by the ATS102

command (the default is 30 ms). After that time, the WAKE_UP line changes its state back to IDLE (high). See Figure 8 for reference.

• Pin assignments:

• g18:

• In the g18, the WAKE_OUT and WAKE_IN functions are on the same physical line called WAKE_UP.

• On the 36-pin connector, the WAKE_UP pin is J10-15.

• On the 28-pin connector, the WAKE_UP pin is J11-9.

• On the 70-pin connector, WAKE_UP function goes to the WAKE_IN_N pin J1-16.

• On the 70-pin connector, WAKE_OUT_N pin J1-26 is not functional.

Hardware Description

Figure 8. Waking Up the DTE when the c18 Should Send Data

3.5.2 c18 Exiting from Sleep Mode

When the c18 senses communication activity on its Rx data line, it exits Sleep mode. Entering Sleep mode again depends on the activity of the network and the activity of the RS232 lines.

3.6 INTERFACES

c18 modules have one or two female MMCX RF connectors (J30 and J31) and an external interface connector. The external interface connector uses one of the following configurations, depending on the c18 model in use:

• 70-pin, 0.5mm pitch, board-to-board connector (J1)

• 36-pin ZIF connector (J10)

• 28-pin DIN connector (J11)

UART signals are low CMOS-level signals (0 to 2.8 V) that can be connected directly to the host UART. c18 input signals (such as TXD, RTS and DTR signals) are buffered, making them capable of receiving signal levels up to 5.0 V. Signals are referenced to the GND.

All unused UART input signals, or input signals that can become disconnected (such as those for cable removal), should be pulled down. The suggested pull-down resistor is a 100k

By setting this line to logical 1, the c18 indicates to the DTE that a connection has

been established with the other side, and that data can now be sent.

Hardware Description

UART1_RI Ring indicator

Using this line, the c18 indicates to the DTE (PC) that there is an incoming call.

Using this line, the c18 indicates to the DTE

UART1_DCD Data carrier detect

(PC) that it has received a carrier signal from the other end of the line.

For standard RS232 communications, such as that required when connecting to a PC, the UART signals must be driven through an RS232 transceiver.

In order to configure the c18 to communicate through UART1, RS232 mode or RS232 + USB mode should be selected by setting the configuration pins (OPT1, OPT2, AUDIO_IN and USB_VBUS). See “c18 OPERATING MODES” on page 17.

If the required mode of communication was set on power-up, the module does not respond to AT commands until the power-up sequence completes. This sequence can take six to seven seconds, and is indicated by the UART1_CTS signal being high. After power-up completes, the module asserts the UART1_CTS signal low, indicating that the module is ready to communicate and receive AT commands.

If the module has been powered up but not configured for RS232 mode, entering RS232 mode is fast. It is indicated by the UART1 CTS signal going low.

3.6.3 UART2

UART2 can support up to a four-wire interface. Two UART2 signals (RXD and CTS) are shared with R-UIM signals (UIM DATA and UIM CLK). For this reason, only one of these interfaces can be used at a time. Figure 12 shows the UART2 interface

UART2 is hardware supported.

3.6.4 USB

The c18 module operates as a full-speed USB device. The interface connector contains USB interface signals, for example, VBUS, D+ and D-. The module contains an integrated USB transceiver, thus eliminating the need for an external one. Integrators should only add an external “B” series receptacle to ensure proper connectivity.

After module power-up, the user should wait for six to seven seconds before attempting to establish USB communication, since the module is unable to communicate at that time.

The following operating systems are supported for USB communication: Windows 2000.

3.6.5 Removable-User Identity Module (R-UIM) Interface

The c18 has optional internal and external R-UIM interfaces. Two R-UIM signals (UIM DATA and UIM CLK) are shared with UART2 signals (RXD and CTS). For this reason, only one of these interfaces can be used at a time. The interface supports 3V cards.

R-UIM is hardware supported.

3.7 AUDIO INTERFACES

c18 has three analog audio interfaces, including:

• Handset interface

• Headset interface

• Hands-free (auxiliary) interface

These interfaces are internally muxed. Therefore, only one interface can be active at a time. The hands-free (auxiliary audio) interface is available for all three types of interface connectors. The handset and headset interfaces are supported only on c18 models that use the 70-pin connector.

The microphone bias source provides 1.8V DC bias (typical), 1 mA. MIC_IN lines should be routed together and kept as short as possible, in order to minimize noise pickup.

The output power for the differential earpiece output is typically 35 mW for a full-scale +3dBm0 sine wave into a 32Ω speaker. The integrator should connect the earpiece speaker through two resistors (with a value of R) for safety compliance, as shown in the figure above.

The resistors purpose is to limit the maximum sound level that can be created by the speaker. The value of R depends on the type of earpiece and its mounting. A value between 0 and tens of Ohms can be expected.

98-08901C63-A 29

Hardware Description

3.7.2 Headset Interface

This interface is single-ended, with both the input and output referenced to analog ground (AGND). The interface is intended for headsets with an active condenser microphone and a 32Ω speaker. The HEADSET_INT_N interrupt line should be used to detect that the headset is plugged in, and to ensure that the c18 selects the required audio path. HEADSET_INT_N is internally pulled up (27 K), and should therefore be shorted to the ground when the headset is connected to the module.

An optional (normally closed) switch can be used for answering/ending (SEND/END) an incoming call from the headset. The c18 monitors the HEADSET_MIC signal DC level, in order to define the state of the SEND/END switch. Be sure to pull down the microphone input when the headset is unplugged from the c18. Figure 15 shows the headset interface:

The output power for the single-ended headset earpiece output is typically 8.8 mW for a full-scale +3dBm0 sine wave into a 32Ω speaker. The integrator should prepare a resistor in series with the headset earpiece (on HEADSET_SP line), in order to provide a means for limiting the maximum output level and to ensure safety compliance.

3.7.3 Hands-free Audio (Auxiliary Audio) Interface

This single-ended interface is intended for car-kit-like applications. Because the audio output is used as an on/off signal (with DC bias on it), an external capacitor should be used (1µF or more), as shown in Figure 16.

All maximum hands-free audio levels specified in this document refer to the 1kH sine wave with a 10kΩ load on the AUDIO_OUT_ONOFF output and a volume set to audio level 3. This load represents input impedance of an amplifier typically used in a car kit. There is no significant change in the audio levels for loads with an impedance higher than 10 kΩ. The module is capable of driving lower impedances as well, down to 600 Ω, but at lower audio levels. For example, the output signal level under the same conditions, but with a 600Ω load is around 300 mVp-p (instead of 1.06 Vp-p with a 10kΩ load).

Muting the external audio circuitry connected to the AUDIO_OUT_ONOFF signal is suggested, in order to reduce "pops" from occurring due to the AUDIO_OUT_ONOFF transitions that occur when the ON/OFF switch is pressed or released. The simplified way to do this is shown in Figure 16.

3.8 ANTENNA

This section describes the available RF antenna connectors and their requirements.

3.8.1 RF Connectors

Description

Two female MMCX antenna connectors are provided for RF input/output in the c18 module:

• Cellular Bands Antenna Connector (J31)

• GPS Antenna Connector (J30)

Both RF connectors (J30 and J31) are 50-ohm connectors with VSWR less than 2:1. Figure 18 shows the c18 module’s antenna connectors.

There are three supported antenna port configurations, as follows:

• A single-port solution that supports CDMA1X/AMPS/GPS bands (with a passive antenna) using the J31 connector.

• A single-port solution that supports CDMA1X/AMPS bands only using the J31 connector.

• A dual-port solution in which the J31 connector is used to support CDMA1X/AMPS only, and the J30 connector is used to support the GPS band (with an active or passive antenna).

J31 covers two cellular bands, 800 MHz and 1900 MHz, as well as the GPS band, 1575 MHz, for passive aGPS.

3.8.1.2 GPS Antenna Connector

J30 is a GPS connector that provides the RF connection to the GPS receiver, as well as a user-defined DC voltage for an active GPS antenna, which may be required in some configurations to increase sensitivity.

The DC voltage is provided by the user on the GPS_ANT_PWR pin on any of the three interconnects, and is routed to J30 via an RF choke to decouple it from the RF signal.

3.9 DISPLAY INTERFACE

This section describes the c18 display interface and its requirements.

3.9.1 Serial LCD

The c18 has an interface for connecting a serial 96x64 LCD. The interface is available only on c18 models using the full-featured 70-pin interface connector. Table 13 describes the pin attributes for the LCD.

Table 13. LCD Pins

56 LCD_DATA

58 LCD_CLK LCD clock rate: 9.6 MHz.

54 LCD_CS_N Chip-select signal (active low).

60 LCD_RS

25 RESOUT_N Reset out from the modem MSM5100 (active low).

Data for serial LCD. Data comes from an 8-bit parallel-to-serial converter.

3.9.2 Backlights

3.9.2.1 KEYB_DRV

The KEYB_DRV output is intended to be a driver for backlight LEDs in handset-like applications. KEYB_DRV is an open drain output used to sink the current. Therefore, the backlight LEDs’ anode should be tied to VCC and the cathode to the c18 KEYB_DRV pin.

Note

By default, the c18 enables this driver on power-up.

This feature is available only on c18 models using a 70-pin interface connector.

An external driver should be implemented if higher drive currents are required.

3.9.2.2 BL_SINK

70 pin connector

Hardware Description

Vcc

Pin #70

KEYB_DRV

The c18 BL_SINK output is an open drain current sink. Therefore, the LEDs’ anode must be tied to VCC and the cathode to the c18 BL_SINK pin. The programmable current sink operates between 0 mA and 40 mA in 16 steps through the SBI register DRV_LCDSEL. The default current is set to 0 mA. These programmable currents are used to control the brightness of the LCD backlight.

Like the keyboard backlight driver, when the sink current is programmed for 0 mA (default), the open drain output is at a high impedance state.

This feature is available only on c18 models using a 70-pin interface connector.

An external driver should be implemented if higher drive currents are required.

Note

This driver is hardware supported.

Hardware Description

3.9.3 LCD_EL_EN

The c18 provides support for controlling an electro-luminescent (EL) lamp. The output enables four levels of intensity control.

3.9.4 Keypad

The keypad interface consists of eight pins, which can be used to connect a matrix keypad and other control buttons (such as volume up/down). Each pin asserts an interrupt if pulled low. All keypad lines have internal pull-ups.

3.9.5 General-purpose A/D Converter - GPADC

The c18 has two general-purpose ADC inputs, ADC1 and ADC2. The GPADC is located in the MSM5100 block. It is intended to digitize DC signals corresponding to analog parameters, such as battery voltage and temperature.

Table 14 lists the GPADC specifications.

I. HARDWARE REQUIREMENTS

FOR CDG2 AND FIELD TESTING

C.1 OVERVIEW

In order to obtain infrastructure approval, equipment containing c18 modules must pass CDG2 testing. The following capabilities must exist to accommodate such testing:

• Capability of sending logs over a second communication channel while the first communication channel is set for AT commands. For this purpose, the c18 supports USB+RS232 mode simultaneously (for supported modes of communication, see “c18 OPERATING MODES” on page 17).

• Integrators must supply the access points and have the ability to support these channels. This includes test points, test connectors and the signals for configuring the c18 in USB+RS232 mode.

C.2 c18 MODELS WITH 36-PIN OR 70-PIN INTERFACE CONNECTORS

In c18 models with 70-pin or 36-pin interface connectors, all pins are available on the interface connector. Integrators should prepare test points or test connectors for the following pins:

For Mode Configuration:

• AUDIO_IN: Must be pulled down with 10

• OPT1: Must be left open for USB+RS232 mode.

• USB_VBUS: Voltage (> 4 V) from the USB port must be present for configuring USB+RS232 mode.

If the c18 model is hardware configured for RS232 mode, you will have to remove R6203 (10K pull-down resistor). For R6203 location, refer to Figure 33.

Note

For Communication With The Logger:

Customers whose primary application communicates with the c18 via UART1 should use the following pins for communicating with the logger:

•USB_D+

•USB_D-

Customers whose primary application communicates with the c18 via USB should use the following pins for communicating with the logger:

• UART1_TXD

• UART1_RXD

• UART1_CTS

• UART1_RTS

To determine whether your specific c18 model is hardware cofigured for RS232 mode, please contact your local sales representative.

Hardware Requirements for CDG2 and Field Testing

C.3 c18 MODELS WITH A 28-PIN INTERFACE CONNECTOR

c18 models that have a 28-pin interface connector, may be supplied in two configurations:

• With hardware preset for RS232 communication mode

• Without hardware preset for RS232 communication mode

The second configuration enables communicating via USB.

Integrators should prepare test connectors or test points for the following pins:

For Configuration:

• AUDIO_IN: Must be pulled down with 10

• USB_VBUS: Voltage (> 4 V) from the USB port must be present for configuring USB+RS232 mode (for configuration and communication).

•OPT1: A 10kΩ pull-down resistor (R6203) on the c18 must be removed when using USB+RS232 mode. The location of the R6203 resistor is shown in Figure 33. R6203 is not installed on c18 models that are not hardware configured for RS232 mode.

Hardware Requirements for CDG2 and Field Testing

In order to use the setup described above for CDG2 testing, the customer must perform the following modification on the c18 module:

• Solder two 0402 size 0Ω chip resistors (R6801 and R6802) on the c18, at the places shown in Figure 35 below.

• Solder a wire from the USB_VBUS PAD (J10, pin #1) to the VBUS test point shown in Figure 34.

Hardware Requirements for CDG2 and Field Testing

Customer applications that have already been completed, which had not implemented the above preparations, will need to access relevant signals on their host boards (such as AUDIO_IN, which is available for the 28-pin connector), or directly on the c18 (using the USB_D+, USB D- and USB_VBUS pins). The location of relevant access points on the c18 is shown in Figure 36.
