11.1 EDK - Does EMC support burst mode with flash?


Keyword: EMC, flash, burst, IP

Does EMC support burst mode when connected to flash?


Burst read with flash from the hardware point of view is not documented in the EMC data sheet, but burst read in the flash device requires the Address Valid (AV) signal. Xilinx EMC does not support this AV signal, and there are no timing parameters associated with this signal as well. So, although the controller supports Burst operations with SRAM, it cannot handle the burst requirements with flash.

If you must use burst for your flash device, you might need to modify the existing EMC controller to support the burst requirements.
