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.
