TUSB6250:Looking for firmware that supports UltraDMA-4

Hi,

We will review this question internally and then provide our response.

Thanks

Hi Noboru,

Yes, there is.  It is available on the product page under software development.  It is called "SLLC444 — CompactFlash Firmware".  Are you having any issues getting it to work?  TUSB6250 data sheet, product information and support | TI.com

As you have said, section 13.5.1 of the datasheet states our CompactFlash firmware supports True-IDE mode. "CompactFlash storage cards are required to support all three types of interface protocols".  Those are PC card memory mode, PC card I/O mode, and True-IDE mode.   

According to section 2.3 of the datasheet the ATA/ATPI controller is a "High-performance DMA engine supports all PIO, multiword DMA, and UDMA transfer modes up to UDMA mode 4 (UDMA-66 or ATA-66)"

Let me know if you have any questions.

Regards,

Nicholaus

Please make note of section 13.4.2.3 in the datasheet:

"To ensure correct functionality, better signal integrity is desired for faster ultra-DMA modes. The optional 80-conductor cable assembly is specified for use with the original 40 connectors. Use of this cable assembly is mandatory for systems operating at ultra-DMA modes greater than 2"
