Audio controller AK5374 that I use requires EEPROM with SPI. However, in the specs it is written, that it communicates with EEPROM via SPI I/F. Will normal EEPROM be compatible with this interface?

    \$\begingroup\$ You'll need an SPI storage device compatible with the commands that chip knows how to issue. Likely what you should do is find a working module or the docs for the eval board they offered, and either use the same SPI chip they used, or use one that seems to have a good match of data sheet details. Beware if they actually read the chip ID and act accordingly, something compatible but with a different chip ID may not work... Fortunately those parts tend to have compatible pinouts so you can try a few times until you find one that works. \$\endgroup\$ – Chris Stratton Apr 25 at 17:51
  • \$\begingroup\$ The official eval board uses an AK6508CT. One challenge you may face is that SPI storage devices are usually flash not EEPROM, while most EEPROMs are I2C. AK seems to have made their audio chip use their own less common (but probably not sole-source) idea of an SPI-interface-EEPROM. But at least there's one part you know works - or would have, as AK have discontinued it with no listed alternative: media.digikey.com/pdf/PCNs/AKM/PD_180406.pdf \$\endgroup\$ – Chris Stratton Apr 25 at 17:53
