轻型电动车仪表盘

概述

这款用于轻型电动车（LEV）的仪表盘采用高度集成的系统级芯片（SoC），该 SoC 由电源管理单元（PMU）、图形处理器（GPU）、蓝牙®低功耗（LE）无线电和独立传感器模块组成。 通过这种配置，仪表盘能够无缝连接并支持多种传感器。

系统优势：

  • 高度集成的蓝牙 LE 设备
  • 带充电器的电源管理单元
  • Arm® Cortex®-M33
  • 传感器节点控制器（SNC）
  • I3C
  • 2D GPU
  • 优化的架构设计，适用于小型外形设计
  • 语音活动检测和关键字检测，用于音频助手
  • 支持 CAN 总线
  • 支持 USB 充电
