TM3与TM4芯片有什么区别?

公司以前用的是TM3现在用的是TM4,不知道两者有什么区别???谢谢

  • Hi tod jiang,

    两者内核不同,之前是Cortex-M3的内核,现在的TM4C为Cortex-M4F的内核,两者外设基本类似;

    另外,附件是从原来的M3到现在的M4的移植手册,可供参考:

    The StellarisWare software development platform has served TI’s Stellaris ARM Cortex-M3 and CortexM4F microcontrollers well since its introduction in 2006. With the expansion of TI's microcontroller offerings to now include multiple series of ARM Cortex-based parts that support different market segments and target applications, however, StellarisWare is becoming TivaWare.

  • 你好,谢谢你的回复。我的意思是TM3这款芯片原本有什么BUG吗,我记的是有部分数据存储不了,会丢失,还有什么问题吗?

  • 不知道您具体使用的哪款芯片,可否详细描述下在使用过程中遇到的问题?

  • LM3S系列的也是很稳定的产品了,如果有你所说的bug,应该早被提出来了,倾向于你操作不当造成的。另外,这款芯片都停产了,还是转向M4吧。
