The Lexar controllers I have seen on Flash media always start with FC.

I am guessing this is a specific one for SSDs.

I suspect that the two pins at J2 are the "ROM mode" shorting points. Perhaps the identity of the controller will be visible in this mode.

Alternatively, try the Rx/Tx test points and see what you get via terminal.

The mystery is solved:

It's a Maxio controller:

Possibly  MAS0902.

[t...@desertdatarecovery.com]

Couldn’t that just be a stock image with Maxio photoshopped?

Both Maxio and Lexar might be buying these drives and rebranding them?

Just a thought.

Maxiotek were spun off from JMicron. They make their own flash controllers.

Perhaps you could try a JMicron loader?

ok shorted points and came ready...

says generic sata device

fw: 0

256 sectors.

FWIW (maybe nothing), there is an SSD tool at the HDD Oracle which purports to be able to dump the firmware of JMicron based SSDs. It can also report the ID of the NAND flash. I don't know if the tool is safe to use, but Google thinks that HDD Oracle is unsafe, so it deletes any post with a link in it.

thanks this look like a tool to talk to the ssd with mas902 chip

I think it needs the right sata board and serial interface.

needs some experimenting.

thanks!
