1 General Description
The FMC B479 SCU PK CGEA 1.3 key is remote unit with Transponder, PASE and Remote
Keyless Entry functionality. 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.

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
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.
FXLS8962AF
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.
