GENERAL DESCRIPTION OF THE RF TRANSMITTER The RF remote control system consists of a RF transmitter and a LF receiver mounted on a control unit. The RF transmitter is mechanically integrated in the head of the key. This transmitter is used to transmit information for locking or unlocking the vehicle by a unidirectional RF transmission line for normal remote operation by pressing a button. Also is implemented the function of the Immobilizer in the transmitter with a bidirectional LF – transmission (passive). In general the following functions are provided: - Lock the car - Unlock the car - Unlock the boot lid of the car - Approach light - Panic alarm - Immobilizer 2. POWER SUPPLY The transmitter is provided with 1 lithium battery (CR 2032) that gives a power supply of +3V. 3. BUTTONS There are five buttons with following functions: Action: Usage: Central locking Activation of Alarm system Pressing the lock button Deactivation of Panic Alarm Pressing the lock button for 1,5 sec. Comfort closing Central unlocking Deactivation of Alarm system Pressing the unlock button Deactivation of Panic Alarm Pressing the unlock button for 1,5 sec. Comfort opening Pressing the unlock button twice within 10 sec. Two-step unlocking De-/activation of Approach Light Deactivation of Panic Alarm Pressing the approach light button Pressing the approach light button for 1,5 sec. Unlocking of Boot lid Pressing the boot lid button Deactivation of Panic Alarm Activation of Panic Alarm Pressing the panic button for 3 sec or pressing it twice within 3 sec. Deactivation of Panic Alarm During activation, the button is forced to the ground via a “pull-up” within the microcontroller.

BLOCK DIAGRAM OF THE TRANSMITTER Circuit description: The central elements of the Transmitter are the controller and LF receiver IC PCF 7953ATJ and the synthesizer PLL – RF-Transmitter PCF7900 from Philips Controller PCF 7953 The PCF7953 is a high performance single chip Security Transponder, Keyless Entry and RISC Controller, ideally suited for automotive applications with combined vehicle Immobilization and Keyless Entry/Start functions. Unless other products, the device comes with a package integrated Transponder LF coil used in combination with the Security Transponder or and Keyless Entry function. The Security Transponder features secure contactless authentication, employing a Secret Key and a random number in order to cipher any communication between the device and the basestation. The basic transponder operation is emulated utilizing the on-chip RISC and may feature a customized operation or may use the built in Transponder Library functions, that offer HT2 compatible operation (e.g. PCF7936). Neither other external components nor an additional battery supply is needed. Keyless Entry operation incorporates a high sensitive 3D LF front-end that offers low power LF Wake-Up detection and LF data communication.

Device operation is controlled by a ROM or E-ROM programmable (FLASH like features) low power 8 Bit RISC controller. The RISC employs a 2 stage pipeline architecture in order to execute an instruction in a single clock cycle. Device timing is derived from an on-chip low tolerance RC Oscillator and programmable system clock, with a frequency up to 2 MHz. The system clock may also be derived from the transponder interface (LF Field clock) or an external clock source. 17 general purpose I/Os are provided for command buttons, LED, or control of an external RF transmitter/transceiver circuitry. Device authentication or rolling code generation may employ the hardwired Calculation Unit that can operate in standard HT2 (48 bit Secret Key) or HT2- Enhanced (64 bit Secret key) mode. In addition an AES compliant operation with a 128 bit Secret Key is provided. Depending on the operation mode, the RISC is powered from the external battery or derives its power supply by inductive coupling (transponder mode) to the LF Field generated by the basestation. The PCF7953ATJ incorporates an advanced power management that supports battery voltage measurement and optional battery charging from the LF Field. The device comes in a 36 pin Leaded Stick Package (LSP). The device is available as E-ROM (FLASH like Features) and in-circuit programming and debugging is supported.

FRANTIC is especially designed for use in the ISM frequency bands (315/434/868/915 MHz). Fine-tuning of the reference oscillator by means of fractional-N synthesis allows compensation of manufacturing tolerances of the crystal. The device also provides an adjustable output power. FRANTIC can be used for both ASK and FSK modulation with data rates up to 40 kBit/s. Due to the high le…

No 1.0 Declaration to Test reports T31116-01-00KJ and T31116-01-01KJ Herewith we declare that the Radio Frequency transmitter 5WK4 9243 fulfilled the requirements according to FCC Part 15 Subpart 15.231(a) and RSS210 Annex A1.1.1 “Signal deactivation”. The unit 5WK4 9243 is a manually operated transmitter. The requirement for this kind of equipment is: “when released the transmitter shall cease transmission within 5 seconds”. The unit 5WK3 9243 cease the transmission in 852ms (see plots at page 27 in Test report T31116-01-00KJ and page 26 in Test report T31116-01-01KJ ). So the requirements are fulfilled. The plots at page 28 in Test report T31116-01-00KJ and page 27 in Test report T31116-01-01KJ shows the automatically signal deactivation time when the button will not be released.
