摘　　要：可变静态存储控制器(FSMC)是STM32系列中的一种存储器扩展方式,FSMC可以根据不同系统的设计应用需求,使其可以在外部连接不同类型的大容量静态存储器,依据外部存储器所独具的特色,满足不同的需求,例如静态随机访问存储器(SRAM),只读存储器(ROM),NOR Flash/NAND Flash,PSRAM等。文章从NOR Flash入手探究其与FSMC的连接通信。Variable static memory controller(FSMC) is a memory expansion mode in STM32 series. FSMC can connect different types of high-capacity static memory externally according to the design and application requirements of different systems, and meet different requirements according to the unique characteristics of external memory, such as static random access memory(SRAM), read only memory(ROM), NOR Flash/NAND Flash, PSRAM, etc. Starting with NOR Flash, this paper explores its connection and communication with FSMC.
