(: 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.
