TMS570LC4357: Maximum SPI flash memory addressing capacity

Part Number: TMS570LC4357


Hi,

Is it possible to address a flash SPI memory of 4Gbit using the MbiSPI peripheral of the TMS570LC4357? What is the maximum capacity that could be addressed using this peripheral? 

Would you suggest any other options to control this size of SPI flash memory?

Best Regards.

    Hi Joel,

    There is no physical limitation. 

    You can read data from or write data to any size of memory connected to SPI interface. To communicate with big memory, more address bytes (defined by memory datasheet) following the Read or Write instruction are required to specify the memory location.
