I am interested in finding the manufacturer of U3 on this SSD device: http://www.engadget.com/2007/02/19/the-do-it-yourself-ssd-adapter/ The device in question is on the underside of the PCB above the letters "25SD". It has a strange Logo that I do not recognize. See : http://akiba.ascii24.com/akiba/news/2006/11/16/imageview/images825461.jpg.html Regards, Richard.
Can anyone identify the manufacturer of this Chip ?

Couldn't start to identify the part with that image. Maybe it looks good on your monitor but I don't care to adjust my monitor settings and get the loop out to try and SEE the logo on that chip in the first place. Might I suggest a better macro lens?

Looks fuzzily-familiar to a Cypress logo. If you tell us the part number we can pin it down.

And the second photo appears to be a woman's hand, which while not incompossible with the name "Richard" is at least unusual.

Looking at the PCB vs the functionality, I'm having trouble understanding why you'd need half the crap on there just to interface 4 SD cards to IDE... and looking at the asking price it would appear that the marketing division have as little clue as the engineering division...

You can do all that in a single CPLD... Regards, -- Mark McDougall, Engineer Virtual Logic Pty Ltd, <http://www.vl.com.au> 21-25 King St, Rockdale, 2216 Ph: +612-9599-3255 Fax: +612-9599-3266

If you say that an FULL ATA compliant high speed multi SD in parallel optimized interface can be done "cost effectivly" in simple CPLD, then this is something that I would say is not so. OR if you are able to implement it, then I should maybe buy an hat. (so that I can take it off, should I meet you). the PCB as on picture sure is using an overkill of components, but replacing them with and small CPLD is also not possible. However an 3USD FPGA maybe already be able todo the task. Antti

I personally would instantly buy this IP (IDE-SD interface that can fit into CPLD), but it is a little more than "simple PLD" to achive this, so I dont expect this to be available. Antti PS, hm just recalled, I have made a MMC (MMC mode, not SPI) mode IP core that can configure FPGA from MMC card, this IP core does take 21 Macrocells (coolrunner-2), other technologies 22 MC. So I think I know what function takes what resources in CPLD/FPGA. A high performance standard compliant IDE-SD interface is not fittable into CPLD (standard CPLD, not counting the cross-over products like machXO/MAX- II to CPLD's)
