Hello,

We are migrating our design from an S25FL132K part to the S25FL064L part. I'm using the same software for both parts, the latest Spansion SLLD. During initialization, the first thing I do is issue an 0xAB command to ensure its out of sleep, then I issue it again with a 4 byte read. On the S25FL132K part, I receive in MISO 0x00 0x15. On the S25FL064L part, MISO is hard zero. See attached Saleae outputs. I cannot find anywhere specifying why this may not work on the factory S25FL064L part. Please help!

Thanks,

Brent

Re: S25FL064L NAND flash not returning data for RDID command

Any ideas?
