Tire Pressure Monitoring System

Overview

Renesas' tire pressure monitoring system monitors real-time air pressure and temperature, alerting drivers of improperly-inflated tires or other safety information immediately.

System Benefits:

  • SmartBond TINY™, the world’s smallest and lowest power Bluetooth® Low Energy (LE) system-on-chip (SoC), brings down the cost of adding Bluetooth LE in automotive systems.
  • Addresses BOM cost reduction through a PCB pattern antenna and a highly integrated low-power Bluetooth LE SoC.
  • No dedicated receiver is necessary in the vehicle infotainment system.
  • A flexible system power management IC (PMIC) can supply a wide range of multicore SoCs and integrates full power rail management with multiple sleep modes for an optimized system solution.
  • Reduces cost and development time using PMICs verified for R-Car SoCs.
  • Reference boards provide a quick and easy start to development.
