Automotive Sensor with CAN/LIN Interface

Overview

This system supports numerous automotive applications, including pressure monitoring (HVAC, oil) and position sensing (liquid levels). It offers a flexible, high-accuracy sensor system equipped with sensor signal conditioners (SSC), DC/DC, MCU, and LIN interface, ensuring reliable performance in diverse automotive environments.

System Benefits:

  • Simplifies SSC integration into car networks with CAN and LIN interfaces.
  • MCU extends SSC capabilities and reduces the processing load on the main ECU.
  • Features easy SSC setup using an existing communication board and user-friendly GUI software.
  • Offers a low-cost reference board add-on for the RL78/F1x Starter Kit.
  • Delivers enhanced system reliability and accuracy with high-precision SSCs.
