USB 2.0 chip recommendation?

G

Georgi Beloev 21 years ago

Hi group,

I need a USB 2.0 high speed (480Mbps) controller recommendation. It should meet most of the following criteria:

- USB 2.0 @ 480 Mbps

- sustained data rate > 20MB/s; preferably > 30 MB/s

- parallel 8-bit or 16-bit interface

- SPI and I2C (in hardware or software)

- general-purpose I/O pins (8 or more)

- easy to use - minimal or no firmware required - drivers available for Windows and/or Linux - high-level API to talk to the drivers - good documentation and example applications

- single-chip solution; small package

- available in small quantities from major distributors

I've used the FT2232C but unfortunately it is not a high-speed device.

Thanks,

-- Georgi

Not many have single chip, small, 480Mbps solutions :

Cypress EZ-USB FX2LP (new), or older EZ-USB FX2 series. They claim 53Mbytes/Sec

I've used the older FX2. It has 8/16 bit FIFO interface and you can use those pins also as GPI0. However, if I remember correcty, you can't have both at the same time(?) Otherwise it seems to match your wishlist quite well...

Depends on the package of the FX...
