瑞萨RH850/F1L系列车规级MCU在汽车电子领域应用广泛,32nm低功耗工艺是汽车电子的一个重要保障,其拥有丰富的车载CAN通讯、LIN通讯、以太网接口通道,以及常规的如SPI通讯,IIC通讯,UART通讯等资源,可用于对集成度要求较高的BCM,以及对通讯接口数量有要求的网关类产品中。


本文介绍瑞萨RH850/F1L系列,176pin的MCU:R7F7010323的SPI通讯设计经验。瑞萨RH850的SPI通讯接口在规格书中被命名为CSI,分为CSIG,CSIH两种,这两个模块并不冲突,CSIH通常被应用于较复杂的SPI通讯系统中,常见的SPI功能仅需要CSIG即可实现。R7F7010323支持2ch CSIG与4ch CSIH,共6路SPI模块。


以CSIG模块为例,介绍瑞萨CSIG模块的硬件设计。如下图1所示,CSIG模块与普通的SPI模块相同,所用到的引脚包括CSIGTSCK,CSIGTSI,CSIGTSO,CSIGTSSI,CSIGTRYI,CSIGTRYO 6个引脚。通常用到时钟脚CSIGTSCK,数据输入脚CSIGTSI,数据输出脚CSIGTSO,与从模式片选脚CSIGTSSI,这4个脚。

图1 瑞萨CSIG模块使用引脚


在设计电路时需要注意,与其它MCU所规定的MOSI,MISO引脚不同,瑞萨的输入输出脚不会随模式的选择而改变。即数据输入脚CSIGTSI,数据输出脚CSIGTSO,在主模式或者从模式时,不会更改其输入输出功能。CSIGTSI应该接对方的SPI输出引脚,CSIGTSO应该接对方MCU的输入引脚。而片选脚CSIGTSSI只有当该MCU被设置为slave时才有效,作为SPI模块的片选使能脚,建议电路如下图2所示:

图2 瑞萨CSIG模块引脚连接示意图


此外,瑞萨R7F7010323芯片CSIG模块在master模式下最高通讯速率可达10Mhz,从模式时可达5Mhz。支持包括仅发,仅收,收发同时三种传输模式。R7F7010323芯片CSIG模块支持handshake功能,通过CSIGTRYI,CSIGTRYO两个引脚来实现该功能,支持自检模式,通过设置内部寄存器将输入,输出脚内部短接进行自检功能。


综上所述,瑞萨RH850/F1L系列芯片R7F7010323支持CSIG,CSIH等多路SPI功能,且支持握手协议,自检功能。在硬件设计中无需考虑主从模式,只需要注意输入输出脚的设计即可,在从模式下,支持片选使用功能,符合SPI通讯需求。
