简介

客户通常希望在他们的实验室里通过几个传感器快速评估 ASi-5。ASi-5 板虽已存在,但缺少传感器,因此需要专用 I/F 来连接到适当的传感器。

他们通常还需要分离处理并卸载其主机 MCU,因此通常需要由传感器板上的专用 MCU 对传感器数据进行预评估。此外,通常还需要 3.3V 或 5V 的电源。

此设计在单一 PCB 上集成了多个传感器、接口、用于传感器数据预评估的专用 MCU 以及电源。

系统优势:

  • 一块板上有多个传感器,用于快速评估
    • 通过 DIP 开关或软件选择传感器
    • 附加的模拟输入
  • RA2A1 MCU 集成了强大、丰富的模拟功能,用于传感器数据预评估/计算
    • 适用于现有 ASi-5 板的 I/F
    • 8-/16-/24 位并行输出,用于简单的 ASi-5 从机
    • 适用于复杂 ASi-5 从机的 SPI
    • 额外的 PMOD I/F 也可连接到大多数瑞萨 MCU 板
  • 单个 3.3V 或 5V 输入,内部产生附加电源轨(3.3V+5V)
