Passive entry passive start (PEPS)
Overview
Our integrated circuits and reference designs help you design passive entry passive start (PEPS) modules and key fobs that are secure and compact while reducing system power consumption and optimizing radio frequency (RF) and vehicle communication latencies.
Design requirements
PEPS automotive systems require:
- Optimized power and range.
- Secure relay attack prevention using Bluetooth Low Energy (BLE).
- Achieve accurate localization using BLE while minimizing the number of nodes.
