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.
