您好，
我正在评估铁路功能安全项目的 S32K344（双核）。我需要知道这种 MCU 是否可用于需要..：
EN 50128（铁路软件功能安全标准）
SIL 3/SIL 4 功能安全等级
另外：
恩智浦是否有支持 SIL 3/4 设计的指南或文档？
对于在关键任务和非关键任务中安全使用双核有什么建议？
提前感谢！
请注意，在圣诞假期期间，我们的支持响应时间可能会比平时长。在某些情况下，您的请求可能会在新年后得到处理。感谢您的理解。
S32K344 根据 ISO 26262 开发，支持 ASIL D，在功能安全完整性方面，ASIL D 与 SIL 3 大致相当。不过，恩智浦并未提供符合 EN 50128 或 SIL 4 标准的认证或声明。如果您的项目需要 EN 50128，则需要使用可用的功能安全文档（功能安全手册、FMEDA 等）自行进行功能安全评估和流程调整。
此致，
Lukas
