基于SPI总线接口的FRAM设计

Application of FRAM Based on the Connection Technology of SPI Bus

介绍了数字信号处理器DSP的SPI接口的特点,并设计了铁电存贮器FRAM与DSP器件TMS320LF2407的SPI接口硬件电路,在分析FRAM器件的工作原理基础上设计了基于SPI通信的DSP与FRAM之间的接口程序.

This paper first introduces the features of DSP SPI interfaces;it gives the detailed hardware design of the SPI interface between FRAM and TMS320LF2407 system. On the basis of analyzing the working principle of FRAM devices,it discusses the software design of SPI communication between DSP and FRAM.
