意法半导体提供广泛的微控制器产品组合,这些产品基于Arm®的Cortex®-M 32位内核,并提供全面的外设选项。其广泛性确保设计工程师能够找到在性能、能效和安全性方面适合其应用需求的产品。

STM32微处理器 (MPU) 及其结合了Arm® Cortex®-A内核与Cortex®-M内核的异构架构的推出,为嵌入式系统工程师提供了新的设计可能性和访问开源Linux和Android平台的途径。STM32系列通用应用处理器可以从32位扩展到64位平台。

这种灵活的架构允许将先进的数字和模拟外设分配到任意一个内核,同时根据处理和实时执行需求实现理想的能效。为了帮助工程师缩短应用开发时间,意法半导体和第三方提供一个完全主线化的开源Linux发行版和新一代系统工具集,现在可用于STM32 MCU和MPU。




STM32和STM8 Finder移动应用

STM8 FinderSTM32 Finder将取代先前的ST MCU Finder移动应用,可提供稳健、便捷的用户体验。 

此类应用可访问意法半导体品类齐全的STM8 8位微控制器、STM32 32位Arm® Cortex®-M微控制器和STM32MP15 Cortex-A7微处理器,以及评估板、探索套件和Nucleo开发板。找到所需产品后,用户可搜索相关的辅助资料,如文档、项目文件和软件。

STM32 Finder应用还可订购作器件和开发板,让用户与Facebook™、Twitter™、STM32 YouTube™频道和ST社区等社交平台上的开发者社区进行互动。
