0 Introduction 

0.1 General 

The F35-XXL concept combines 32 bit CPU core, Dual Band GSM engine, 

12 channel GPS receiver, 2 audio interfaces (on the 120pin-connector), 8 

digital I/Os and 8 digital or analogue inputs. The 1 MB SRAM- and 1 MB 

Flash-memory (optional 2+2) on board allow the creation of a large variety 

of applications including extensive data logging. 

The eCos system software builds the basis for quick and easy development 

of your own application firmware using high level programming languages 

(GNU tools). The external access to the internal system bus can be used for 

debugging purposes as well as for your own hardware extensions. The 

ability to update your own application firmware over the air link reduces 

time and cost for field testing and after sales support providing very high 

flexibility in responding to the dynamic range of end user requirements. 

Thus the F35-XXL concept brings together powerful state-of-the art 

technologies (GSM, GPS, internet) and makes them available for quick and 

easy integration into a number of applications for the vertical and horizontal 

market. 

The table below shows the combination versions of the F35-XXL-basis.

1 Security 

IMPORTANT FOR THE EFFICIENT AND SAFE OPERATION OF 

YOUR GSM-MODEM, READ THIS INFORMATION BEFORE USE! 

Your cellular engine F35-XXL is one of the most exciting and innovative 

electronic products ever developed. With it you can stay in contact with 

your office, your home, emergency services and others, wherever service is 

provided. 

This chapter contains important information for the safe and reliable use of 

the F35-XXL. Please read this chapter carefully before starting to use the 

cellular engine F35-XXL. 

1.1 General information 

Your F35-XXL utilises the GSM standard for cellular technology. GSM is a 

newer radio frequency („RF“) technology than the current FM technology 

that has been used for radio communications for decades. The GSM 

standard has been established for use in the European community and 

elsewhere. 

Your modem is actually a low power radio transmitter and receiver. It sends 

out and receives radio frequency energy. When you use your modem, the 

cellular system handling your calls controls both the radio frequency and the 

power level of your cellular modem. 

1.2 Exposure to RF energy 

There has been some public concern about possible health effects of using 

GSM modem. Although research on health effects from RF energy has 

focused for many years on the current RF technology, scientists have begun 

research regarding newer radio technologies, such as GSM. After existing 

research had been reviewed, and after compliance to all applicable safety 

standards had been tested, it has been concluded that the product is fit for 

use. 

If you are concerned about exposure to RF energy there are things you can 

do to minimise exposure. Obviously, limiting the duration of your calls will 

reduce your exposure to RF energy. In addition, you can reduce RF 

exposure by operating your cellular modem efficiently by following the 

guidelines below. 

1.3 Efficient modem operation 

In order to operate your modem at the lowest power level, consistent with 

satisfactory call quality please take note of the following hints. 

If your modem has an extendible antenna, extend it fully. Some models 

allow you to place a call with the antenna retracted. However your modem 

operates more efficiently with the antenna fully extended. 

Do not hold the antenna when the modem is „IN USE“. Holding the antenna 

affects call quality and may cause the modem to operate at a higher power 

level than needed. 


Page 9


1.4 Antenna care and replacement 

Do not use the modem with a damaged antenna. If a damaged antenna 

comes into contact with the skin, a minor burn may result. Replace a 

damaged antenna immediately. Consult your manual to see if you may 

change the antenna yourself. If so, use only a manufacturer-approved 

antenna. Otherwise, have your antenna repaired by a qualified technician. 

Use only the supplied or approved antenna. Unauthorised antennas, 

modifications or attachments could damage the modem and may contravene 

local RF emission regulations or invalidate type approval. 

1.5 Driving 

Check the laws and regulations on the use of cellular devices in the area 

where you drive. Always obey them. Also, when using your modem while 

driving, please pay full attention to driving, pull off the road and park before 

making or answering a call if driving conditions so require. When 

applications are prepared for mobile use they should fulfil road-safety 

instructions of the current law! 

1.6 Electronic devices 

Most electronic equipment, for example in hospitals and motor vehicles is 

shielded from RF energy. However RF energy may affect some 

malfunctioning or improperly shielded electronic equipment. 

1.7 Vehicle electronic equipment 

Check your vehicle manufacturer's representative to determine if any on 

board electronic equipment is adequately shielded from RF energy. 

1.8 Medical electronic equipment 

Consult the manufacturer of any personal medical devices (such as 

pacemakers, hearing aids, etc.) to determine if they are adequately shielded 

from external RF energy. 

Turn your F35-XXL OFF in health care facilities when any regulations 

posted in the area instruct you to do so. Hospitals or health care facilities 

may be using RF monitoring equipment. 

1.9 Aircraft 

Turn your F35-XXL OFF before boarding any aircraft. 

Use it on the ground only with crew permission. Do not use it in the air. 

To prevent possible interference with aircraft systems, Federal Aviation 

Administration (FAA) regulations require you to have permission from a 

crew member to use your modem while the plane is on the ground. To 

prevent interference with cellular systems, local RF regulations prohibit 

using your modem whilst airborne. 


Page 10


1.10 Children 

Do not allow children to play with your F35-XXL. It is not a toy. Children 

could hurt themselves or others (by poking themselves or others in the eye 

with the antenna, for example). Children could damage the modem or make 

calls that increase your modem bills. 

1.11 Blasting areas 

To avoid interfering with blasting operations, turn your unit OFF when in a 

"blasting area" or in areas posted: „turn off two-way radio“. Construction 

crew often use remote control RF devices to set off explosives. 

1.12 Potentially explosive atmospheres 

Turn your F35-XXL OFF when in any area with a potentially explosive 

atmosphere. It is rare, but your modem or its accessories could generate 

sparks. Sparks in such areas could cause an explosion or fire resulting in 

bodily injury or even death. 

Areas with a potentially explosive atmosphere are often, but not always, 

clearly marked. They include fuelling areas such as petrol stations; below 

decks on boats; fuel or chemical transfer or storage facilities; and areas 

where the air contains chemicals or particles, such as grain, dust or metal 

powders. 

Do not transport or store flammable gas, liquid or explosives, in the 

compartment of your vehicle which contains your modem or accessories. 

Before using your modem in a vehicle powered by liquefied petroleum gas 

(such as propane or butane) ensure that the vehicle complies with the 

relevant fire and safety regulations of the country in which the vehicle is to 

be used. 

1.13 Non-ionising radiation 

As with other mobile radio transmitting equipment users are advised that for 

satisfactory operation and for the safety of personnel, it is recommended 

that no part of the human body be allowed to come too close to the antenna 

during operation of the equipment. 

The radio equipment shall be connected to the antenna via a non-radiating 

50 Ohm coaxial cable. 

The antenna shall be mounted in such a position that no part of the human 

body will normally rest close to any part of the antenna. It is also 

recommended to use the equipment not close to medical devices as for 

example hearing aids and pacemakers. 


Page 11


2 Safety standards 

The GSM core complies with all applicable RF safety standards. 

The embedded GMS modem meets the safety standards for RF receivers 

and the standards and recommendations for the protection of public 

exposure to RF electromagnetic energy established by government bodies 

and professional organizations, such as directives of the European 

Community, Directorate General V in matters of radio frequency 

electromagnetic energy.

5.2 Hardware interface 

5.2.1 Interface for external 3 V SIM card reader 

The F35-XXL has an integrated SIM interface compatible with the ISO 

7816-3 IC card standard. This is wired to the host interface in order to be 

adapted to an external SIM card holder. 

Six pins on the interface are reserved for the SIM interface. 

Note: The SIM should not be removed, while the module is under power. 

The SIM must only be removed when the F35-XXL is shut down. 

Only SIM card readers should be used in which the eject button 

contact is activated before the other contacts are released! 

Note: The line lengths must be less 15 cm and lower than 10pF , the line 

length is relevant to the approval procedure. 

Note: The unit is not designed for use of single 5 V SIM cards. These 

cards will generate an error which cannot be distinguished from a 

faulty SIM card (� error message the same as that for faulty SIM 

card). 

To take advantage of this feature, an appropriate contact is required on the 

card holder. For example, this is true for the model supplied by Ensure that 

the card holder on your application platform be wired to output a high signal 

when the SIM card is present.

PIN 94/96 

PIN 82/84 

PIN 70/72 

The F35-XXL engine comprises two audio interfaces, each with an analog 

microphone input and an analog earpiece output. 

All microphone inputs and outputs are balanced. 

To suit several types of equipment, there are six audio modes available 

which can be selected by the AT^SNFS command. For example, sending 

and receiving amplification, side tone paths, noise suppression etc. depend 

on the selected mode and can be set by AT commands. 

Detailed instructions on using AT commands are presented in the AT 

Command set of the MC39i, see chapter 0.3 (Related documents), item [2]. 

Figure 6: Audio interface of the F35-XXL 

5.2.3 Serial interface 

The MC39i module provides a full-featured serial interface designed to 

easily control the MC39i engine and to handle data transmission. It operates 

at CMOS level (2.65 V). 

Note: The MC39i is internal connected to the UART A (SER2) like a 

DCE:

For more details see chapter “ Ring- ”. 

The data interface is implemented as a serial asynchronous transmitter and 

receiver conforming to ITU-T RS232 Interchange Circuits DCE. It has fixed 

parameters of 8 data bits, no parity and 1 stop bit and can be selected in the 

range of 1.2 kbps up to 115 kbps for auto bauding and in the range of 300 

baud to 115 kbps for manual settings. Hardware handshake using signals 

RTS0/CTS0 and software flow control via XON/XOFF are supported. 

In addition, the modem control signals DTR *) , DSR and DCD are available. 

Different modes of operation can be handled by AT commands. 

For more information about signal levels of the serial interface see chapter 

4. 

5.2.4 Control signals 

*) The DTR signal will only be polled once per second from the 

internal firmware of MC39i! 

The following control signals are available (2.65 V CMOS level). 

5.2.4.1 Ring- MC39i 

The RING0- MC39i pin is connected to the RI-UART pin. 

The behaviour of the RING0 line depends on the type of the call received. 

- When a voice call comes in the RI line goes low for 1 s and high for 

another 4 s. Every 5 seconds the ring string is generated and sent over 

the RXD0 line. 

If there is a call in progress and call waiting is activated for a connected 

handset or hands free device, the RING0 witches to ground in order to 

generate acoustic signals that indicate the waiting call. 


Page 29


Figure 7: Incoming voice call 

- Likewise, when a fax or data call is received, RING0 goes low. 

However, in contrast to voice calls, the line remains low. Every 5 

seconds the ring string is generated and sent over the RXD0 line. 

Figure 8: Incoming data call 

- An incoming SMS can be indicated by an Unsolicited Result Code 

(URC) which causes the RI line to go low for 1 second only. Using the 

AT+CNMI command you can configure the engine whether or not to 

send URC’s upon the receipt of SMS. For instance, enter 

AT+CNMI=1,1 to activate URC’s for incoming short messages. For 

more details please refer to the “TC3x AT command set”.

5.2.4.2 SYNC to control a status LED 

The SYNC Pin of the MC39i is available on the 120 pin connector, see 

chapter 4 -Pin assignment and signal levels. 

As an alternative to generating the synchronization signal, the SYNC pin 

can be used to control a status LED on your application platform. 

To avail of this feature you need to set the SYNC pin to mode 1 by using the 

AT^SSYNC command. 

For details please see chapter 0.3 (Related documents), item [2]. 

When controlled from the SYNC pin the LED can display the following 

functions: 

LED mode Function 

Off *) MC39i is off, in SLEEP, Alarm or Charge-only mode. 

600 ms On/ 

600 ms Off *) 

75 ms On/

interactions). No call in progress. 

Depending on type of call: 

�Voice call: Connected to remote party. 

�Data call: Connected to remote party or exchange of 

parameters while setting up or disconnecting a call.

5.2.5 General propose input/output 

During and after system reset, high impedance is set at all GPIx and GPIOx 

pins. 

In order to connect a 5V external outputs to the 3.3V CMOS inputs of F35- 

XXL(-SI) module is to use a 10k upto 100k pull up resistors (R) to 3.3V 

line and an open drain or open collector output at the 5V side. See attached 

block diagram below. 

You can also use a common level shifter chip which shift the voltage level 

from a 5 V device level downwards to a 3.3 V . 

5.2.6 General pin configuration 

Pin 63 (GPIX1(USA) Power Good) 

The power good signal can be used to signalize the F35-XXL-SI a 

sufficient power supply on pin 115, 117, 119. It can be read by the NEC 

V850 on port 83 and is pulled up to 3.3V by 100 kOhm. The pin can be 

left disconnected or can be connected to an open collector or open drain 

output. A low level on this pin disables the low drop power regulator of 

the power supply of the MC39i GSM module. In this case the MC39i is 

connected straight to the VC5. This is important if the MC39i works in 

IDLE mode or power down mode, because the low drop regulator 

consumes power for itself. If the pin 63 GPIX1 (PWR_GOOD) is 

pulled down (i.e. the power is not good), you must not supply the F35- 

XXL-SI with 5V!!! The Voltage must not exceed 4.5V. The regulator is 

switched off in that case and cannot compensate the ripples of the MC- 

35 power supply. But if the MC39i is powered down, the regulator does 

not waste current. 

Pin 41 (IGNITION) 

The ignition pin is connected to the NEC V850 port 07. This pin can 

trigger a user interrupt. The suggested purpose is the detection of the 

car ignition voltage. Note that additional hardware is necessary for the 

connection to car voltage. 

Pin 15 (WakeUP) 

The wake-up-signal is connected to the NEC V850 port 80. It can be 

used for digital or analogue input or for digital output. The suggested 

purpose is to wake up the V850 from sub-clock mode. It can be left 

disconnected. (Note that disconnected CMOS ports must be 

programmed as pull up input or as output.) 


Page 32


Pin 43 (INTU) 

The INTU signal is connected to the NEC V850 port 06. It can trigger a 

user interrupt. (Note that disconnected CMOS ports must be 

programmed as pull up input or as output.) 

Pin 29 (EMODE) 

If the e-mode input pin is connected to GND (10 kOhm) the F35-XXL- 

SI boots from the external FLASH, otherwise it boots from the internal 

ROM. 

Pin 61 (NMI) 

The NMI pin is connected to the NEC V850 port 00. The NMI can 

wake up the V850 from the HALT mode. For programming the NMI 

refer to the NEC manual for the V850/SA1(UPD70F3017AY) 

hardware. 

Pin 106 (BootSel) 

For normal GPS functionality this pin has to be left open while the 

GPS-firmware is starting. After the start of the GPS-firmware the pin 

(106) can be connected to 3.3 V. In that case the first GPS-Port is 

switched to the pins (98, 100) on the 120-pin connector. In order to 

reprogram the FLASH of the GPS (e.g. updating a new firmware), this 

pin (106) has to be set to high (+3.3 V DC) before the internal GPSfirmware 

is started. 

Pin 101 (AVGND) 

In order to use the analogue inputs, the AVGND pin has to be 

connected to the reference voltage ground (usual the ground plane near 

the reference voltage source). 

To use the GPI1 to GPI8 for analogue input follow the instructions 

below: 

• Connect AVGND to the GND. 

• Connect AVDD to a voltage up to 4.6V. 

• Connect AVREF to a reference voltage up to AVDD (2.5V or 

2.56, recommended). 

• See "demo_port_io.c" for software. 

• Refer to the NEC manual for the V850/SA1(UPD70F3017AY) 

hardware. 

GPS (GPIO’s) 

As far as the GPS GPIO’s is concerned, there is no access from the 

NEC V850 processor. These pins are to be controlled by internal GPS 

firmware. Unfortunately, the present GPS firmware does not support 

these pins, but these are depended on the GPS firmware loaded into the 

GPS FLASH memory.

6.1 Technical data 

FEATURES 

- 12 channel GPS receiver 

- power consumption: 220 mW (continuous mode with Low Power 

chipset) 

60 mW (trickle power mode) 

- protocol: RXA/TXA: 

NMEA 4800 baud, Msg.: GLL, GGA, RMC, 

VTG, GSV, GSA, ZDA 

8 data bits, no parity, 1 stop bit 

RXB/TXB:

- Trickle power mode: The F35-XXL enters the trickle power mode 

corresponding to figure 11 as soon as valid 

GPS data are available. As a result the 

average power consumption is reduced by 

approximately 80 % (approximately 60 mW). 

The settings for the trickle power mode can 

be modified using the SiRFstar demo 

software. For example if the F35-XXL is 

configured to enter the OnTime mode each 

10 s for a duration of 200 ms the average 

power consumption can be reduced by 

approximately 95 % (approximately 15 mW, 

ca. 4,8 mA at Vcc=3.3 V).

EEPROM 

The Microchip Technology 32kB EEPROM 24LC32 with serial interface 

is integrated to store device configuration data. 

In order to get access the on board EEPROM into the F35-XXL(-SI), two 

functions are supported setenv() and getenv().To read the EPROM using 

the getenv() function, and to know more about its memory state as 

well as to remove any of the KEYS in order to free the EEPROM memory, 

the follow demo application, can be used. 

//* consider that the follow application is a demo for EEPROM 

environment access for the F35-XXL(-SI), only. 

#include 

#include 

#include 

#define dprintf diag_printf 

static char *my_env[] = {"TEST_KEY=test key value from my_env", 

"TEST=1234=5678", "TEST2=ABCDEFG", 

NULL}; 

static const char pszKey[]="TEST_KEY"; 

static const char pszIniValue[]="TEST KEY VALUE FROM EEPROM"; 

int main(void) 

{ 

char *p; 

dprintf("F35-XXL EEPROM access demo\n"); 

dprintf("set environment variable to \"my_env\"\n"); 

//if the environ variable points to an environment array, 

//the getenv() function reads this values. 

environ = (char **)&my_env; 

dprintf("reading key %s\n",pszKey); 

p = getenv(pszKey); 

if (p) { 

dprintf("%s=%s\n",pszKey,p); 

} 

else { 

dprintf("key %s not found...\n",pszKey); 

} 

dprintf("set environment variable to NULL\n"); 

// if the environ variable is NULL, then the environment 

//functions will work 

// with the F35-XXL(-SI)’s EEPROM.

The PCF8593 real time clock is a low-power clock/calendar with 2-wire 

serial bus connection to the NEC V850 controller. 

Reset/watch dog 

The supervisor chip MAX6366 realises the power on reset and watches 

dog functionality. After reset the watch dog is automatically triggered by 

the CPLD. After the first software trigger the watch dog is active and 

must be triggered 1 time per 500 ms or faster. 

The hardware watchdog chip MAX6366 is part of the F35-XXL(-SI).The 

timeout period is between 1 second and 2.25 seconds. 

Without a trigger signal the device performs a reset after this 

time. The watchdog is triggered by input or output on the address 

0x3FFFF8. 

The sequence for disabling the watchdog is: 

write-read-write-write-read-write-write-write 

(write the value 0xE5 to the address 0x3FFFF8 ) 

The next input or output on 0x3FFFF8 enables the watchdog. 

A watchdog device is available in eCos. 

Insert it with "ecosconfig add watchdog". 

#include // printf 

#include // cyg_thread_delay 

#include // watchdog class 

int main(){ 

int i; 

printf("starting watchdog\n"); 

Cyg_Watchdog::watchdog.start();

8 Getting started 

8.1 Determining the External Equipment Type 

Before you connect the F35-XXL(-SI) terminal (DCE unit) to external 

equipment, you need to determine if the external hardware serial ports are 

configured as DTE or DCE. 

The terms DTE (Data Terminal Equipment) and DCE (Data 

Communications Equipment) are typically used to describe serial ports on 

devices. Computers (PCs) generally use DTE connectors and 

communication devices such as modems and DSU/CSU devices generally 

use DCE connectors. As a general rule, DTE ports connect to DCE ports via 

straight through pinned cables. In other words, a DTE port never connects 

directly to another DTE port. Similarly, a DCE port never connects directly 

to another DCE port. The signaling definitions were written from the 

perspective of the DTE device; therefore, a Receive Data signal becomes an 

input to DTE but an output from DCE. 

The F35-XXL(-SI) is designed for use as a DCE unit. Based on the 

aforementioned conventions for DCE-DTE connections it communicates 

with the customer application (DTE) using the following signals: 

GSM Terminal (DCE) to Application (DTE)

14 Appendix 

14.1 How to put the F35-XXL(SI) into the Sleep Mode? 

In order to put to put the F35-XXL-SI into the sleep mode follow steps 

described below: 

• Turn off the GSM engine. 

• Turn off the GPS engine. 

• Set the ST16C654 UART into the power save mode 

• Mask all interrupts (except for wakeup) 

• Make sure, the code for execution during the sub-clock mode is 

placed in the internally RAM. (The external RAM goes into 

sleep mode without access.) 

• Finally, set the V850 into the desired power save mode. 

For additional information refer to the V850 hardware manual and the 

power demo application „demo_power.c“. 

14.2 How to communicate with extra external I2C devices? 

A eCos device driver is available for access to the I2C bus: 

.../packages/devs/wallclock/v85x/falxxl/current/src/v85x_v850_i2c.c 

Examples for access are likewise in this directory: 

.../packages/devs/wallclock/v85x/falxxl/current/src/v85x_v850_env.c 

.../packages/devs/wallclock/v85x/falxxl/current/src/wallclock_8593.cxx 

The reserved slave addresses of the internal I2C devices are: 

EEPROM 24LC32A - 0xa0/0xa1 

WALLCLOCK PCF8593 - 0xa2/0xa3 

14.3 How to update programmatically your software into the 

FLASH? 

A possible way for firmware upload is the transfer of the binary image into 

the RAM and to copy the RAM content into the FLASH. You can use the 

FLASH tools in „cyg/io/flash.h“. We haven't a complete software solution 

for this yet. 

14.4 How are the pins of 120-pin connector connected to the NEC 

V850?
