Connection of SPI Flash in ADAU1452

Hi, ADI Support Team

 

I'd like to confirm how much size can connect SPI Flash in ADAU1452.
I find the following description in the datasheet (Page 41 of Rev.C).

----------------------------------------------------------------------------------

The slave EEPROM has 16- or 24-bit addressing, giving it a total memory size of between 4 kb and 64 Mb.

----------------------------------------------------------------------------------
From this description, I understand that 64Mbit (8MByte) is limit for ADAU1452.

Is it hardware limitation of ADAU1452?

 

However, I want to connect more bigger SPI Flash (e.g. 32MByte, 64MByte, etc.).

Do you have any solution for this?

 

Best regards, TomY
