The transponder function is based on the Immo frontend inside the microcontroller and one of the external LF coils. The PASE function is part of the PEPS protocol (Passive Entry and Passive Start) that provides enhanced customer convenience and  security  via  a  customer  carried,  passively  or  actively  enabled  Passive  Key  (PK) communicating with the vehicle through an RF Receiver (RFM) to the BCM with an integrated PEPS microcontroller.      1.1  Variant Overview      Variant Description   Characteristic     FORD    Continental    K1BT-14K601-DA  A2C17105000 USA & Canada 3 Button variant (434MHz Multi channel) with ST Logo       1.2  Multichannel characteristic      Frequency channel 1: 434,251 MHz ±43 kHz   Frequency channel 2: 433,589 MHz ±43 kHz
  I BS R&D    3    11.06.2018                         2 Main components      2.1  UHF-Transmitter Token      The  Token  NCF29A1  is  an  extremely  single  chip  solution  that  incorporates  a  Security Transponder, UHF Transmitter RISC controller on the same chip. The device provides a fully integrated fractional-N phase locked loop (PLL) frequency synthesizer and a power amplifier to drive an external antenna. The Token is especially designed for use in the ISM frequency bands.          2.2  Microcontroller FXLS8962AF      The FXLS8962AF is a compact 3-axis MEMS accelerometer designed for use in a wide range of automotive (convenience and security), industrial, and medical IOT applications that require ultra-low-power wake-up on motion.   FXLS8962AF is available in a 2 mm x 2 mm x 0.95 mm 10-pin DFN package with 0.4 mm pitch  and  wettable  flanks.  The  device  is  qualified  to  AEC-Q100  and  operates  over  the extended –40 °C to +105 °C temperature range.   The  combination  of  sensor  performance,  system  power-saving  features  and  extended overtemperature-range performance makes FXLS8962AF an ideal accelerometer for motion sensing in the automotive industry.                  3 Functionality         3.1  Remote keyless entry       -  Lock, Unlock, Trunk unlock   -  Generating and transmitting an RF bit stream for remote entry functions         3.2  Transponder Start authentication      Communicating bi-directionally, LF/LF for authentication / remobilization if keyless vehicle not work due to flat battery.
  I BS R&D    4    11.06.2018                         3.3  Passive Entry and Passive Start   3.3.1  Passive Entry   Passive entry process is the authentication of the PK and BCM to enable unlocking and locking of the vehicle among other functions requiring a PK search on the interior of the vehicle.       The vehicle can be unlocked or locked as follows:   - Trunk open function: PK shall be on the outside rear of the vehicle   - Trunk close: No PK inside the trunk OR if there is a PK inside the trunk, the vehicle shall not be in the armed state.   - Right side entry/locking: PK shall be on the outside right of the vehicle   - Left side entry/locking: PK shall be on the outside left of the vehicle   3.3.2  Passive Start   The Passive Start process is the authentication of the PK and the BCM for enabling the power pack.   For the Passive Entry Passive Start, key authorization time must be less than or equal to 285ms from the initial customer start command to sending the authorization to the BCM   3.4  Mechanical key      Key blade is inside the key.      3.5  Remote Keyless Entry function      When a button is pressed, the microcontroller wakes up and calculates a unique telegram, which  is  sent  to  the  vehicle  by  modulating  an  RF  oscillator.  The  telegram  contains  the information, which button is pressed.   After transmitting (buttons released) the key returns into sleep mode to save battery power.      3.6  Transponder function      The transponder function is part of the immobilizer system and allows authenticating the key and starting the engine independent from the key battery voltage level.    For  that  the  key  will  be  inserted  in  the  ignition  lock  with  immobilizer  base  station.  The immobilizer  base  station  will  charge  the  transponder  with  an  LF  field  and  send  an authentication request. After having received sufficient energy the transponder will answer the request. This is recognized by the immobilizer base station and decoded. If the data stream transmitted by the transponder fits to the expected data stream the immobilizer base station will send a start engine message to the engine control.
