Is it possible to program the ADAU1462 without an EEPROM?
Thread Summary
The user asked if the ADAU1462 can be programmed from a microcontroller without an on-board EEPROM. The support engineer confirmed that the DSP can be booted and programmed via the slave control port using I2C or SPI. The user found the provided wiki page with example code helpful.AI Generated Content
I'm getting started designing a board with the ADAU1462 and I'd like to avoid adding an EEPROM on board if possible and instead opt to program it from the microprocessor that acts as its I2C controller. Is this functionality supported or will I have to incorporate an EEPROM on board?
Hello YutongGu,
Yes, you can boot/program the DSP from an external controller and can control the parameters in real time. There are separate control ports for self boot EEPROM and uC control. You have to use the slave control port to program the DSP from a uC either by I2C or SPI.
If you want to know more about interfacing uC with sigmaDSP, then please visit this wiki page.

Got it, thank you so much. The Wiki page had a example code that proved to be helpful!
