SJA1124是一个4通道本地互连网(LIN)主通道器件。4个通道中的每一个通道都包含一个LIN主控制器和带主终端的LIN收发器。LIN主帧通过LIN物理层传输到物理LIN总线。

SJA1124主要面向使用波特率高达20kBd的车载子网络，符合LIN 2.0、LIN 2.1、LIN 2.2、LIN 2.2A、ISO17987-4:2016 (12V LIN)和SAE J2602-1。

串行外设接口(SPI)和中断输出提供了SJA1124与微控制器之间的接口。

特性

一般特性

  • 4个LIN主通道：
    • LIN主控制器
    • LIN收发器
    • LIN主终端，由一个二极管和一个上拉电阻组成。
  • 低功耗模式下电流消耗非常低，通过SLP或LIN引脚唤醒
  • 通过INHN输出控制外部稳压器的选项
  • 总线信号整形优化，波特率高达20kBd
  • 适用于微控制器通信的串行外设接口(SPI)：
    • 用于配置、控制、诊断和LIN数据传输的SPI
    • SPI长度灵活，从3字节到18字节
    • 输出状态引脚表明SPI工作状态
  • 中断输出引脚：中断可单独配置
  • 促进多个SJA1124器件之间的同步LIN帧传输
  • VIO输入允许直接连接3.3V和5V微控制器

LIN主控制器

  • 每个LIN通道均独立：
    • 波特率
    • 工作模式
    • 状态和中断
  • 完整的LIN帧处理和传输
  • 每个LIN帧1个中断
  • 从器件响应超时检测
  • 中断长度可设置
  • 自动同步字段生成
  • 停止位长度可设置
  • 硬件奇偶校验生成
  • 硬件或软件校验和生成
  • 故障限制
  • 分数波特率发生器

保护

  • 卓越的电磁抗扰性(EMI)
  • 极高的ESD强韧性：LIN1至LIN4引脚和BAT引脚符合IEC61000-4-2的±6kV。
  • 在汽车环境中，对总线端子和电池引脚提供抗瞬态保护(ISO7637)
  • LIN主导超时功能
  • 热保护

标准/认证

  • LIN 2.0、LIN 2.1、LIN 2.2、LIN 2.2A
  • ISO17987-3:2016、ISO17987-4:2016 (12V LIN)
  • SAE J2602-1
