木牛 安全库 s32k14x 产品手册说明书
知从木牛SAFETYLIBRARY 恩智浦S32K14X产品手册知从®木牛基础软件平台功能安全库1功能概述S32K14x Safety Library用于帮助客户实现基于S32K14x平台的功能安全要求。
Safety Library具有高扩展性，可以根据不同的客户项目要求进行配置和再开发，最终满足客户的功能安全需求。
S32K14x Safety Library用于实现S32K14x平台的软件安全机制，包括MCU内部模块的测试和硬件安全机制的驱动。
2应用领域S32K14x Safety Library可应用于有功能安全等级需求的控制器。
例如：车身控制器电池管理系统(BMS)网关控制器车载娱乐模块胎压监控系统门控单元车灯控制单元电子驻车制动系统通过将Safety Library集成到基于S32K14x平台的控制器中，可达到ISO26262 ASIL-B的等级要求。
3配置环境4开发背景目前，汽车上的电子电气架构越来越复杂，对汽车电子的安全性要求也越来越高，为了满足汽车的安全性需求，汽车功能安全越来越受到重视。
提到功能安全，大家首先想到的是功能安全的标准ISO26262。
其中，ISO 26262-5(2011) Clause 8中介绍了2个度量：Single-point fault metric(单点故障度量)和Latent-fault metric(潜伏故障度量)。
根据不同的ASIL等级要求，单点故障度量和潜伏故障度量需要达到相应的等级。
对于微控制器(MCU，以下简称MCU)，在电子电气系统中，作为SEooC(safety element outof context)进行设计开发。
MCU为了满足以上提到的2个度量要求，需要实现相应的安全机制。
而安全机制可以分配到硬件和软件模块中。
MCU的Safety Library安全库就是实现分配到软件上的安全机制。
5功能描述5.1产品特点可作为复杂驱动集成到AUTOSAR中满足控制器ASIL-B需求可集成到非AUTOSAR软件架构中高扩展性：每个模块实现可配置性，满足不同的客户需求 Safety Library内部程序流监控5.2软件架构5.3配置工具为了满足客户的不同项目需求，提高Safety Library的扩展性，S32K14X Safety Library 实现了各个模块可配置性，并且实现了Safety Library的配置工具。

s32k144和ad7606接口设计与实现
电子技术Electronic Technology电子技术与软件工程Electronic Technology & Software Engineering S32K144和AD7606接□设计与实现文/唐鸿华•(株洲中车时代电气股份有限公司 湖南省株洲市412001 )摘 要：本文针对S32K144外接AD7606的AD 转换电路，采用FlexIO 接口方式进行连接。
本文描述了具体的设计和实现方法，并验 证了设计的正确性。
关键词：S32K144; FlexIO; AD7606; SPI;嵌入式1引言S32K 系列单片机是NXP 推出的汽车电子类单片机，适合高可 靠性设计中使用。
S32K 的软件开发可使用免费的S32DS 开发环境，该开发环境对应芯片的内部模块配置采用可视化模式，同时S32K的软件开发包提供内部模块的底层驱动。
设计人员在开发过程中只需关心具体应用，使用方便。
S32K144单片机由于内部AD 转换精度有限，当转换精度要求 高于1%时，通常采用外接AD 转换芯片方式。
使用串行通信可降低PCB 布线复杂度。
S32K144单片机包含有一个FlexIO 模块，这 个模块可根据需要配置成UART 、SPI 、I2C 等多种串行通信模式。
采用了带SPI 接口的AD7606芯片作为外部AD 转换芯片。
2硬件接口设计AD7606 通 过 SPI 接口与 S32K144 通信。
FlexIO 是 S32K144 系列芯片内的一个通信模块，可配置成SPI 通信模式。
FlexIO 模块的8个外部引脚任意一个均可配置成SPI 的4根通信信号线的任意一个，如在PCB 布局中发现布线交叉复杂时，可调整引脚布局简化PCB 布线。
S32K144与AD7606的硬件连接如图1。
AD7606芯片的通信方式选择(nPAR/SER/BYTE SEL)配置为高电平，表示使用SPI 方式通信。
S32K144发出启动转换信号(CONVSTA 、CONVSTB)到 AD7606, AD7606 开始数据转换，这时BUSY 信号为高电平；当BUSY 信号为低时，表示转换完成。
s32k芯片命名规则
s32k芯片命名规则
S32K芯片的命名规则一般包含以下信息：
1. S32K系列名称：该系列名称表示芯片所属的系列，例如S32K144等。
2. 数字部分：这部分表示芯片的型号和规格，包括芯片的位数、主频、封装等信息。
例如，数字部分为144，表示该芯片为32位MCU，并且主频为48MHz。
3. 后缀部分：该部分通常表示芯片的封装形式和温度范围。
例如，后缀为TQFP，表示该芯片采用TQFP封装；后缀为-40~105℃，表示该芯片的工作温度范围为-40℃~105℃。
综上所述，S32K芯片的命名规则可以帮助用户了解芯片的规格和特点，从而更好地选择和使用该芯片。
恩智浦半导体FlexIO模拟通信和定时外设应用笔记说明书
恩智浦半导体文档编号：AN12174 应用笔记第0版，2018年6月使用 FlexIO 模拟通信和定时外设1. 简介FlexIO 是用在 Kinetis 和 S32K 微控制器系列上的新外设模块。
它具有高度可配置性，能够模拟各种通信协议，例如本文档中提到的UART、I2C、SPI、I2S和LIN，以及其它一些通讯协议，像J1850、I3C、曼彻斯特。
FlexIO 作为微控制器的一个独立外设模块，并不能替代任何通信外设。
FlexIO 的主要特点是可以根据用户的需求来直接构建自己的外设。

S32K144之时钟配置
S32K144之时钟配置⼀般来说，时钟精度、稳定性取决于所采⽤的时钟源，就MCU S32K来说如内部振荡器SIRC，FIRC，128KLPO，外部晶振等，跟所使⽤的外设（FTM, LPIT，LPT，RTC等）和哪⼀路输出时钟（SYS_CLK，BUS_CLK，SPLLDVI1_CLK等）没有直接关系。
由于S32K144提供的时钟源和配置⽅法⽐较多，那么如何有效配置得到⾃⼰想要的时钟呢？下⾯以S32K144为例，从时钟定义图开始，逐步介绍如何寻找S32K144时钟（CORE_CLK, BUS_CLK,）合适的配置⽅法，并根据测试⽅法验证配置是否有效。
0. ⽬标输出⽬标clock clock= 80MHz（以下MHz简称M）bus clock=40MHz， Normal Mode（默认）注意：只有⽀持105℃的部分S32K144型号，core clock才能⽀持到最⾼112M（HSRUN），其他型号不论HSRUN模式，还是RUN模式，最⾼⽀持80M。
测试⼯具PCB: S32K144EVB-Q100IDE: S32DS for ARM 2018.R11.时钟定义配置时钟先从学会看时钟分配图开始，会看图了，配置就成功了⼀半。
因为能实现⽬标的路径可能有多种，这⾥先选中⼀条配置路径，再判断是否可⾏（蓝⾊箭头+框）。
时钟源选择外部晶振8M，即SOSC=8M => SPLL时钟源 SPLL_CLK_SOURCE = SOSC = 8M，2.确认内部时钟要求CORE_CLK/ SYS_CLK 最⾼⽀持112M(HSRUN) , 80M(RUN)，⽬标@80M符合要求。
不过，BUS_CLK最⾼⽀持56M(HSRUN), 48M(RUN)，⽬标@40M符合要求。
3.确认外部晶振 8M查看S32KEVB-Q100评估板原理图，知外部晶振8M => System PLL输⼊ SPLL_SOURCE=8M4.确认System PLL分频及倍频这⾥选择PREDIV=0, MULT=0b11000 (10进制： 24)VCO_CLK=8M/(0+1) X (24+16) = 320MHzSPLL_CLK=(VCO_CLK)/2 = 160MHz考虑：这⾥MULTI还可以>24 => 倍频因⼦>40，那么能不能配置VCO_CLK >320M，⽽最终CORE_CLK=80M呢？答案是不⾏，因为VCO_CLK最⾼⽀持到320M，可以参考S32K-RM。

S32K144例程源码
S32K144是一款高性能的微控制器，广泛应用于各种嵌入式系统。
以下是一个简单的S32K144例程源码，用于演示如何使用该微控制器的PWM功能。
在上面的代码中，我们首先包含了S32K144的头文件，然后定义了主函数。
在主函数中，我们首先初始化了PWM模块，然后在无限循环中设置了PWM周期为1秒，占空比为50%，并启动了PWM波形输出。
接着，我们等待一段时间，
然后停止PWM波形输出。
这个例程可以用来演示如何使用S32K144的PWM功能，并且可以通过修改PWM周期和占空比的值来改变PWM波形的输出。
