Audio delay (0-160ms) problem with ADAU1761

Dear All!

I would like to delay (0-160ms) on a differential sound line with ADAU1761. But when I tried to
set more than 86ms, the Sigmastudio says the RAM address exceeds:4096. I read
about it. I found that delay is the limit with built in data memory.
I would like to ask can I use external data memory for this DSP?
Could you give some idea how can I make a delay line and volume control on
differential line? I would like to make a simply and esy circuit and the Sigma
DSP looks like good, but problem with the memory.

Thanks your answers.
