ADAU1452: How to use the external delay

Question asked by Beni on May 28, 2015
Latest reply on Jul 9, 2015 by Beni


I try to use a Microchip 23LC1024 as external delay SPI RAM with the ADAU1452.

On the ADAU1452MINIZ evalboard i replaced the selfboot eeprom with the RAM chip.

When i look at the SPI signals it seems that the external delay algorithm addresses the SPI RAM with a 16 bit address (because the algorithm was designed for the 23K256 ).

The 23LC1024 chip needs a 24 bit address.

My question is:

How can the 23LC1024 be used as SPI RAM for the external delay block ?

How can the address width be set to 24 bits ?


Please help
