：本文首先介绍了FRAM 的特点； 然后在分析了FRAM 配置及DSP的SPI通信模块的基础上

。给出了FM25L256与

TMS320F2812 DSP的接t：／电路的硬件设计。最后，文章给出了SPI模块初始化程序及DSP与FRAM之间接t：／程序设计。

关Illir, 3：FRAM；SPI；DSP系统：通信-: This article first introduces the characteristics of FRAM　then in the analysis of FRAM configurations and DSP-SPI communication module basis. FM25L256 with the TMS320F2812 DSP is given the access t:/circuit hardware design. Finally, the article gives the SPI module initialization procedures and the DSP and the FRAM indirect t:/programming.
