Introduction

This user's guide provides setup and usage instructions for the Car Access Reference System (CARS) featuring
Remote Keyless Entry (RKE), Passive Entry/Passive Start (PEPS), Ultra-Wideband (UWB) distance measurement
and vehicle Immobilizer (IMMO) functionality, based on the Microchip's GEN2 communication protocols. It offers a
complete car access system for various car access products and its evaluation. The reference designs are both
scalable and configurable through either the PC application or source code modifications, enabling adaptation of
the basic hardware and software building blocks to meet the most recent requirements for specialized systems. For
example, the UWB reference design board is not required if the UWB functionality is not being evaluated.

Features

Full Car Access System Capability:
– Vehicle IMMO
– Multichannel RF RKE
– LF PEPS
– Identifying relay attack with UWB distance measurement
Open System Software:
– Open Immobilizer Protocol (OIP) immobilizer stack using AES-128
– RKE RF rolling code using AES-128
– PEPS protocol with a high-precision 3D localization using AES-128
– Scalable and configurable
– PC Graphical User Interface (GUI) for system visualization and viewing data communication
