Hi,
Since all SPI device are obselete... I found as a replacment the part AT25SF041. It sounds to fulfill the requirement of TI. But I don't know if TUSB9261 is using Write Status Register (05h) since new device require to send command Write Enable for Volatile Status Register (50h) prior to (05h).
or
Can the device work directly without external SPI device? Is there a default firmware into the TUSB9261?
If the answer is yes, which SATA pin swap is program into it?
Thanks,
