SYSTEM OVERVIEW The RF remote control system consists of a RF transmitter and a RF receiver. 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 as also Trunk Lid/Approach Light/Panic/comfort open/Comfort Close operations by an unidirectional RF transmission line for normal remote operation by pressing a button. The information will be transmitted on the first channel and afterwards also on the second channel. 2. POWER SUPPLY The transmitter is provided with 1 Lithium battery (CR 2430) that gives a tension of feeding of +3V. The battery inversion is protected mechanically. 3. BUTTONS All buttons are on the top side of the key housing. They are arranged in the following way.

Annex No.7 Page 1 of 5 Block Diagram Functional description Key: 5WK4 9264 BLOCK DIAGRAMM 5WK49264 The block diagram below shows the main electronic units of the transmitter: EE PROMTransponder Power Management RISC Processor Power Supply RF STAGE Buttons 14,75MHz temperature sensor Functional description Remote Key (RK) The Remote Key system consists of the following functional blocks, which can be identified in the block diagram: • Power supply • Microcontroller • Contact less immobilizer interface • User interface (Buttons) • RF stage Power supply The Remote Key is supplied by a single lithium coin cell CR2430. Microcontroller The Philips PCF7945ATT microcontroller is based on an 8Bit Harward architecture RISC core and integrates, among others, these features: • Internal firmware ROM • Internal application Flash-ROM • Internal RAM • Immobilizer security transponder functionality • Internal RC oscillator for CPU clock • Internal temperature sensor Contact less immobilizer interface Immobilizer interface consists of an external tuned LC circuit connected to the microcontroller. User interface (Buttons) For user interaction, the RK is equipped with 5 mechanical buttons. Button signals are low active and are handled by the microcontroller. RF stage RF stage includes the RK's loop antenna. Main component is the Chipcon CC1070 transmitter IC. It is contains a programmable fractional N PLL synthesizer controlling transmission frequency. It integrates also the PLL reference oscillator to which an external high precision crystal is connected. Further the IC takes care of data encoding (e.g. MANCHESTER) and modulation according to the programmable parameters. Global functionality Immobilizer Transponder mode: The microcontroller in combination with the contact less interface circuitry acts as security transponder when coupled to a base station triggering this mode. No RF transmission is used in this operation mode. Remote Key Mode: Triggered from a button press initiated by a user, the microcontroller wakes from sleep mode and initialises the registers of the RF IC needed for operation. Information from internal sensor is used to compensate for temperature related frequency drift of PLL reference crystal. Button information is transmitted to the receiver unit on car side using a defined telegram structure. The Remote Key is a dual channel system and two frequencies within the same frequency band are used for transmission. The same button information is transmitted once per RF channel on short button presses. Longer button presses result in additional comfort telegrams being transmitted, alternating between RF channels, to inform the car about this fact.
