简介

基于 Arm® Cortex®-R4 实时微处理器(MPU)的 RZ/T1 系列与我们的高精度 32 通道 LED 背光驱动器相结合,能够控制用于最先进电视的大型矩阵 LED 背光系统。 集成驱动器反馈通道允许对 LED 电源的电压水平进行控制,以动态地将整体功耗最小化。 数字系统和接口电源由一个 处理器电源管理集成电路 (PMIC) 和高效降压转换器提供。 AT25QLxx 系列的 QSPI 闪存被用于软件和亮度映射存储。 传感器如 温度 有助于优化系统在不同条件下的性能。

系统优势:

  • 灵活的,基于 MPU的,软件控制的,大型矩阵亮度和色度控制
  • 用于将 LED 调节和视频内容之间的传播延迟降到最低,以最小化视频缓冲区大小的 RZ/T1 MPU
  • 动态 LED 电源电压调整,以最大限度地减少电能损耗
  • 高度集成且高效的系统 PMIC
  • 来自 LLC 的单一可变电压轨为 LED 和系统电源供电
  • 用于优化系统性能的温度和环境光传感器
