I realize that this is an old thread, but I'm curious if you did go with the ISD1750? If so, I'd be interested in hearing how it went.

I'm also updating an old project that used a now obsolete Winbond chip. I thought I could simply pulse the FWD input to get to the desired recording, but the ISD chip responds too slowly that way. I'm going to pursue the SPI interface, next. If there's any interest, I'll post my results.

I'm new to this forum, so I'm not sure if I should post here or start a new thread dedicated to interfacing with the ISD chips. Anyone have a suggestion?
