摘　　要：针对嵌入式微控制器内部自带RAM资源的不足,本文介绍了一种扩展外部SRAM数据存储空间的设计方案。系统采用飞思卡尔Kinetis平台的K60系列MCU,外部SRAM选择ISSI公司的IS61WV102416BLL高速CMOS存储芯片。并自行设计了一款低成本的高速反相器,通过Kinetis平台自带的FlexBus总线模块实现外部SRAM数据存储空间的内存映射,满足了一般高端嵌入式产品需求。Aiming at the lack of resources of internal RAM for embedded microcontroller, a design project of extending external SRAM data storage is introduced. The system adopts K60 series MCU based on Freescale Kinetis platform,and takes ISSI corporation＇s high- speed CMOS storage chip as the external SRAM. And the system designs a low-cost and high-speed inverter through the Kinetis platform with FlexBus module. It achieves memory mapped of external SRAM data storage space, and satisfies generally high-end embedded product requirement.
