Flash Memory

Automatic configuration of SDRAM is not optimized for any SCLK fre- quency. Table 1-3shows optimized configuration for the SDRAM registers using a 125 MHz and 133 MHz SCLK. Only the EBIU_SDRRC reg- ister needs to be modified in the user code to achieve maximum performance.

Flash Memory

The flash memory interface of the ADSP-BF538FEZ-KIT Lite can con- nect to an external 4 MB (2M x 16-bits) ST Micro M29W320EB device or the 1 MB internal flash memory. The size and connections of flash memory are controlled by the flash address range switch (SW6) and the flash chip enable (FCE) switch (SW14). See “Flash Enable Switch (SW6)” on page 2-11and “FCE Enable Switch (SW14)” on page 2-12.

The default for the SW6 switch is all positions ON, which allows the user to have access to the full 4 MB of the external flash memory. The default for the SW14 switch is all positions OFF, which allows the user to have access to the full 4 MB of the external flash memory. Each ~AMS signal accounts for 1 MB of flash memory. The amount of available flash memory decreases as ~AMS signals are turned OFF.
