ADAU1452 - Question on EEPROM Properties
Thread Summary
The user inquired about the compatibility and configuration of a WinBond W25Q80DVSNIG 8-Mbit SPI EEPROM with their ADU1452 DSP design. The Analog Devices support engineer confirmed that the EEPROM design is correct, the Sigma Studio EEPROM properties are appropriate, and the ADU1452 DSP supports 8-Mbit SPI EEPROMs due to its 24-bit addressing capability.AI Generated Content
We have designed an ADU1452 DSP into our new product. We based the Self Boot SPI EEPROM on the ADAU1452 EVK. This used:
Microchip 25AA1024 EEPROM 1M-bit (1048576 bits) 512 pages - 256 bytes each. Max clock 20 MHz. We chose a larger EEPROM device:
WinBond W25Q80DVSNIG, 8-Mbit (8,388,608 bits) 4096 pages - 256 bytes each. Max clock 104 MHz.
I have three questions:
1.) Could you review our DSP schematic attached to confirm the EEPROM design is correct?
2.) Are the Sigma Studio EEPROM Properties properties below correct for an 8-Mbit EEPROM?
2,) Does SigmaStudio 4.7 and the ADAU1452 DSP support 8M-bit SPI EEPROMs? (I could not find an answer to this in the datasheet.
Thanks for your support!

Hello jpierson,
1)The connection between your DSP and the EEPROM resembles our eval board design, so it's just fine to follow Eval board's design.
2)Yes, your properties window seems correct for this particular memory.
3) For SPI, since the master control port supports 24 bits addressing, so you can connect your 8Mbit memory with our DSP.

Harish
