Instrument Panel for Light Electric Vehicles

Overview

This instrument panel for light electric vehicles (LEV) utilizes a highly integrated system-on-chip (SoC) that consists of a power management unit (PMU), a graphical processor (GPU), a Bluetooth® Low Energy (LE) radio, and an independent sensor block. With this setup, the panel seamlessly connects and supports a wide range of sensors.

System Benefits:

  • Highly integrated Bluetooth LE device
  • Power management unit with charger
  • Arm® Cortex®-M33
  • Sensor node controller (SNC)
  • I3C
  • 2D GPU
  • Optimize architecture for small form factor design
  • Voice activity detection and keyword detection for audio assistance
  • CAN bus support
  • USB charging support
