Hi,

8 bit micros can not handle full traffic of ide interface.16F84 even can't handle usb traffic! It is too slow to do it :)

What about C8051F321 (www.cygnal.com)?

It's a 25MIPS 8051 CPU with USB 2.0 Function Controller.

The Cygnal part is not a USB 2.0 Function controller !
It is only compatiple with the 2.0 spec (like almost all USB 1.1 devices.

It can only handle 12 MBit and 1.5 MBit datarates .

Hi dainis,

you mean Cypress can send me samples of this chip?
I can't find any info about requesting samples on the site...
Can you please show me how to do it?

I also wrote a letter to www.smsc.com they have a pretty good
USB to ATA bridge too, but they did not answered... :(

I would like to get a sample USB to ATA chip to test with my
MP3 project.

Can anyone help me?

Thanks,
Zedman

Look:
http://www.elektroda.pl/eboard/viewtopic.php?t=29525

Cypress is sampling the ISD-300LP(TM) (CY7C68310) low-power mass-storage controller. Compatible with all industry-standard ATA/ATAPI devices, the ISD-300LP enables portable computer users to take their mass-storage subsystems with them without the need to plug into wall outlets.

But it looks like you can only order Programmable System-on-Chip (PSoC) devices.
Yupp, and now iam sad... :cry:

Even microchip is discontinued shipping samples here...
Now I should burn down 2-3 expensive chips to get a thing work, and
than buy one that will be in the project... damn :)

Thanks,
Zed
