ADSP-21573/ADSP-SC573 and external SRAM

Good day! I have simple question about ADSP-21573/ADSP-SC573. Can external memory controller of ADSP-21573 and ADSP-SC573 work with external SRAM? There is some SMC - this is what we need or it's for something else? We need an analog of AMI from 489 family. This is necessary for connecting NVSRAM as well as for communication with FPGA.

    Hi Mikhail,

    Yes, the static memory controller (SMC) of SC573 is a protocol converter and data transfer interface between the internal processor bus and the external L3 memory. It provides a glueless interface to various external memories and peripheral devices, including:
    SRAM
    ROM
    EPROM
    NOR flash memory
    FPGA/ASIC devices


    The SMC acts as an SCB slave. The processor SCB interconnect fabric arbitrates accesses to the SMC. On the chip boundary, the SMC connects to an address bus, a data bus, and signal pins for memory control (such as read, write, output enable, and memory select lines)

    For more information please refer the  chapter 10 Static Memory Controller (SMC) int he SC573 HRM, http://www.analog.com/media/en/dsp-documentation/processor-manuals/adsp-sc57x-2157x_hwr.pdf

    Best Regards,
