Can we use SRAM instead of SDRAM in RX72N design. RX72N Datasheet recommends for SDRAM. According to the datasheet Independent SDRAM area (128 Mbytes) and max. operating frequency of 80 MHz. We want to use RMWV6416A has max density of 64Mb with RX72N
Hello Prosun,
RX72N includes a specific area called External address space (CS area) dedicated to be used with memories such as SRAMs:
Υοu can download an app note with sample code (it has been designed for RX72M, but it can be used as reference for RX72N device) from the link below:
https://www.renesas.com/en/document/scd/rx-family-example-using-external-bus-rev100?r=1170206
Τhe sample code has been designed to be used with CY7C1061AV33-10ZXI SRAM model (1 M words x 16 bits).
