There are two versions of the Nokia 12:
RX-2 dual-band GSM device supporting EDGE, GPRS, HSCSD, CSD, and SMS in EGSM 900/GSM 1800 MHz bands RX-9 dual band GSM device supporting EDGE, GPRS, CSD, SMS in GSM 850/GSM 1900 MHZ bands. The Nokia 12 can be used in several applications due to its three different operating modes. Simple I/O applications can be easily implemented using the Nokia 12 in the User control mode that offers message personalising, secure messaging, and timing functionality for SMS controlled I/O applications. Additional intelligence for I/O applications can easily be implemented with Java. In the AT command mode, the Nokia 12 can be used as a GSM modem that supports Java for creating extra intelligence. In modem use, all supported bearers are available, subject to network support. The Nokia 12 is compatible with the Nokia M2M Platform. In the M2M system mode, the Nokia 12 communicates with the server application through the Nokia M2M Gateway, and all the compatible features of the Nokia 12 are available for developing a wide range of M2M applications. In addition to these operating modes, the Nokia 12 has an integrated TCP/IP stack which enables direct GPRS or GSM data connection between a remote end application and a server application. Due to the integrated TCP/IP stack, the HTTP and Socket APIs of the Nokia 12 are available for application development. In addition to the bearers and operating modes listed above, the Nokia 12 supports several Java APIs, location service for external GPS module integration, reliability features like AutoPIN, GSM encryption and security codes, reset mechanism and Nokia M2M Platform authentication. Java technology support enables upgrading the application software over the air, and smart messaging makes the installation flexible. GSM phase 2+ supplementary services enable developing voice applications. Note that all data bearers as well as TCP/IP are dependent on network support. This document describes the main characteristics of the Nokia 12 and is intended to help the system integrator both integrate the Nokia 12 in an application and gain the correct approvals. Basic product information is available in Ref 1. 2. MECHANICAL INTEGRATION The Nokia 12 contains two holes for mounting screws. The screws can be used in mounting, but are not compulsory. The Nokia 12 has been tested according to the automotive standard DIN 72300-3. The module can be assembled to various applications without the screws. Copyright Nokia 2003-2004.

ELECTRICAL INTEGRATION 3.1 M2M SYSTEM CONNECTOR All signals are routed through the M2M system connector, except the antenna, which is routed through the MMCX RF connector. The M2M system connector is a 60-pin (2 rows, 30 per row) 1.27 mm pitch pin header connector. It has a frame that helps in the assembly and also holds the Nokia 12 firmly in position. The possible mating connector is described in Table 1. Supplier SAMTEC SAMTEC Part Number SFMC-130-02-S-D SFM-130-02-S-D Description Female connector. Board-to-board Female connector. Board-to-board.

All rights reserved. 11/26 3.2 GROUNDING There is only one common ground for the power supply and I/Os in the Nokia 12 GSM module. There are no separate analog/digital ground pins in the M2M system connector. All ground pins must be connected together at the application end. Grounding through screws is not allowed. The mounting screws must be isolated from the application ground. 3.3 POWER SUPPLY The Nokia 12 GSM module is powered by an application. The operating voltage must not fall below the specification limit under any circumstances. The recommended operation conditions are shown in Table 3. For example, at full power, the TX can be up to 2 A, when current drawn from the power supply. There are no capacitors on the power supply line of the Nokia 12, so the application must provide sufficient filtering. The power supply must be capable of supplying at least 3 W average power, but it is recommended that the power supply provides also the peak current. Otherwise a large capacitor bank is needed to compensate the voltage drop during transmit bursts. The Nokia 12 does not have protection for over-voltage of current, so the application must be equipped with one if there is a possibility for over-voltage. The application should at least include a fuse. The ripple on the operating voltage must not exceed 100 mV and the voltage must never drop below 3.6 V during operation. The application must also produce IO voltage. The logic levels of digital inputs and outputs correspond to this IO voltage. IO voltage can be supplied from a linear regulator. Figure 3 Example powering with simple DC/DC converter and linear regulator Copyright Nokia 2003-2004. All rights reserved. 12/26 3.4 SERIAL COMMUNICATION The Nokia 12 GSM module is accessible through three different asynchronous serial interfaces with different protocols. The pins provide one asynchronous channel with a simple handshaking capability. The first asynchronous channel is provided by PORT1. This port can be used with full 8 signal RS-
232 handshaking signals. The second asynchronous channel is provided by PORT2 with a simple handshaking capability
(only RTS and CTS). The third asynchronous channel is provided by PORT3 with no hardware handshakes. The usage of ports can be configured with the Nokia 12 Configurator software. Nokia 12 Configurator is downloadable at www.forum.nokia.com free of charge. Serial communication speeds for all serial ports can be selected between 9600 115 200 bps. 3.4.1 AT command mode PORT1 can be set to the AT command mode by setting a 68 kohm resistor between BSI (pin 37) and the ground. The Nokia 12 GSM module has to be re-started (power off/on) to identify the resistor. The Nokia 12 provides all signals for the industry standard DB9 RS-232C connection. An external level converter is required. The Nokia 12 is DCE (Data Communication Equipment) and the application is DTE (Data Terminal Equipment). One possible method of implementing the level conversions is to use MAX3237 or an equivalent level converter IC. If BSI (pin 37) is left floating in the application, all PORT1 handshaking pins can be used as a general I/O. 3.4.2 M2M system mode PORT2 uses the M2M system protocol. PORT3 can also be used by the JAVA Imlet as a serial port or as digital input and output pins. 3.5 SIM INTERFACE All leads from the M2M system connector to the SIM card reader must be shorter than 15 cm, because the voltage drop and increasing capacitance will affect timing. Only an external component besides the SIM card reader is a bypass capacitor in the VSIM line (100 n recommended, as close as possible to the reader). The leads between the Nokia 12 M2M system connector and the SIM card reader must be protected against interferences. The striplines must be placed to the interlayers, never to the PWB overlayer. A possible SIM card reader supplier is shown in Table 12. Copyright Nokia 2003-2004. All rights reserved. 13/26 Supplier Amphenol Part Number M-C707_10M006_522_2 Description SIM reader with lid open indication switch Table 12 Possible SIM card reader supplier DATA N C G ND 7 5 5 3 2 1 CLK RST VSIM Figure 4 SIM connections The Nokia 12 GSM module supports 1.8 V and 3 V SIM cards. The Nokia 12 automatically sets the correct voltage for the SIM card used. The SIM card reader must have a switch that indicates when the SIM card is being removed, so that it can be shut down correctly by the Nokia 12. The switch must open when the card is removed or the lid is open. The Nokia 12 has a pull-up in the SIM detection line, so the application must connect the other end of the switch to the ground. 3.6 AUDIO INTERFACE 3.6.1 Analog Audio The M2M system connector gives possibilities to build different kind of audio applications around the Nokia12. Copyright Nokia 2003-2004. All rights reserved. 14/26 The analog TX path (from the external application to the Nokia 12 GSM module) has a DC isolation inside the Nokia 12 with 100 nF capacitors, and these capacitors together with the microphone preamplifier input impedance form a 1st order high pass filter with 32 Hz roll off (-3 dB).

There are also other possibilities for using the Nokia 12 audio interface. The component values presented here are examples only; the customer can adjust the application-specific values to achieve the best performance for the application in use. Copyright Nokia 2003-2004. All rights reserved. 15/26 3.6.2 Analog audio example Analog TX path: Due to the small audio signal level of the electret microphone, it is recommended to use a pre-amplifier for the microphone before connecting it to the Nokia 12 GSM module. The differential connection is strongly recommended to protect against RF noise. A microphone pre-amplifier with 20 dB input gain is recommended for reasonable uplink audio levels. Microphone input: See Figure 5. R4 VANA

C2 C3 MicP MicN Figure 5 Single-ended microphone pre-amplifier Analog RX path: In voice applications, the Nokia 12 is able to drive an earphone application without external electronics. However, it is also possible to build a high volume loudspeaker application by using an external power amplifier with a high sensitivity loudspeaker. The following chapters show example circuits for both cases. Earphone application: An earphone can be connected to the Nokia 12 GSM module without external components. However, Figure 6 shows external components for EMC purposes to optimise audio quality and reliability. Copyright Nokia 2003-2004. All rights reserved. 16/26 R1 R2 L1 C1 C2 J1 J2 Figure 6 Earphone application circuit The recommended earphone type is dynamic. The maximum allowed load for this application is 32 ohm. In the example circuit, L1 is the common mode choke for the suppression of common mode disturbance in the earphone lines. J1 and J2 are surge protector gaps for ESD protection. These can be replaced with varistor or any other state-of-the-art ESD protection component. C1 and C2 are used for RF noise filtering. R1 and R2 are used as an attenuator if the signal level from the Nokia 12 is too high for the application. These resistors can be replaced with linear potentiometers and thus get adjustable volume control for the earphone application. The following component list gives example values for the circuit:
L1= 1000ohm@100MHz C1=C2=27pF R1=R2= Must be defined together with the sensitivity of the earphone External Audio Power amplifier: External audio power must be used if there is intent to drive low impedance load as loudspeaker. In Figure 7 an example connection circuit for differential audio boomer is shown. In this application only the connection interface to the Nokia 12 is presented. For more detailed information on the boomer connections and specification, see the boomer manufacturer application note. Copyright Nokia 2003-2004.

Also keep in mind the limitation of Vdd to avoid overdriving the Audio Boomer and thus distorting the output signal unnecessarily. 3.6.3 Acoustic Echo Because in a GSM voice call the uplink and downlink audios are activated at the same time, use common sense when evaluating a suitable distance between the loudspeaker and the microphone. The acoustic echo canceller inside the Nokia 12 is tuned so that the optimum result is achieved with 20 cm or longer distance between the microphone and the speaker. It is also advisable to locate the microphone and the loudspeaker so that they are pointed away from each other to achieve the best possible double-talk performance. 3.7 DIGITAL AUDIO There is a PCM codec interface in the Nokia 12 for digital audio support. The digital audio interface supports sign-extended 13-bit linear code (total 16 bits are transmitted). Copyright Nokia 2003-2004. All rights reserved. 18/26 3.7.1 Sign-Extended Linear Code PCM (Pulse Code Modulation) digital audio data transmission between the Nokia 12 and the application is handled with four signals: PCMDCLK, PCMSCLK, PCMTX, and PCMRX. The format of the data transmission is sign-extended 13-bit linear code. Total of 16 bits are transmitted, and higher order bits must be sign-extended. Transmission of data commences after frame sync
(PCMSCLK) rises high for one PCMDCLK clock cycle. After returning low, each data bit is transmitted on the falling edge of PCMDCLK. PCMDClk PCMSClk PCMTxData PCMRxData Figure 8 MSB Sign extended 15 14 13 12 11 10 Sign extended MSB LSB 0 LSB Both PCMDCLK and PCMSCLK must be provided by the application. PCMDCLK frequency is 512 kHz and PCMSCLK is repeated at 8 kHz, i.e. at every 64th clock cycle. All other but the 16 data bits following the frame sync are discarded. PCMDCLK has typical duty-cycle of 50 %; a variation of 5
% can be tolerated. For detailed timing, refer to Figure 9 and Table 15. Tcyc is the cycle time of the 512 kHz clock, that is 1.953 microseconds. The PCMSCLK rising edge must occur at the maximum of 8 ns after the PCMSCLK rising edge. The pulse width of the Frame Sync pulse should be one Data Clock cycle.

RF AND ANTENNA INTEGRATION There are two versions of the Nokia 12:
RX-2 dual-band GSM device supporting EDGE, GPRS, HSCSD, CSD, and SMS in EGSM 900/GSM 1800 MHz bands RX-9 dual band GSM device supporting EDGE, GPRS, CSD, SMS in GSM 850/GSM 1900 MHZ bands. RX-2 12 RF requirements follow the ETSI EGSM900/GSM1800 phase2+ specifications. RX-9 12 RF requirements follow the ETSI GSM850/GSM1900 phase2+ specifications. Parameter RF impedance RF power Value 50 ohm 2W (class 4) 1W (class 1) Description EGSM900 & GSM 850 GSM1800 & GSM 1900 Table 16 Nokia 12 RF specifications The RF signal from the Nokia 12 to an external antenna goes trough the MMCX connector. An adapter cable between the MMCX connector and the antenna may be needed. Suitable connectors and cables are available for example from Amphenol, TYCO, and IMS Connector Systems. The Nokia 12 GSM module is certified with a Smarteq dual-band antenna (art no: 1140.26 for 900/1800MHz and 1140.27 for 850/1900MHz). Suitable antennas are available for example from Smarteq and Hirschmann. See also 6.2.5 RF Exposure. 4.1 ANTENNA INSTALLATION The antenna must be placed to a good RF field; a location where the signal strength is adequate. A hand-portable phone can be used to check the best location for the antenna. Electronic devices can cause interference, which affects the performance of the Nokia 12. Do not place the antenna close to electric devices or other antennas. If an additional cable is needed between the antenna and the Nokia 12, use low-loss cables (for example RG-58. Amphenol, Suhner, etc.) and connectors. Every additional cable, adapter, and connector increases the loss of signal power. See also 6.2.5 RF Exposure. Copyright Nokia 2003-2004. All rights reserved. 20/26 When designing the application, it is important to take care of RF emissions. Do not place any sensitive components or striplines near the antenna or the antenna connector. 5.
